When the Past Teaches the Future: Earthquake and Tsunami Risk Reduction through Episodes of Situated Learning (ESL)

: The past offers important lessons with regard to facing the future with greater awareness. In this context, school plays a key role in spreading knowledge of natural phenomena and in promoting behavior change. Together with researchers, teachers can be strong allies to build more resilient future citizens. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) school training activities provide tools to prepare for the next earthquake and/or tsunami. Approximately 5000 students, from both middle schools (ISCED 2) and high schools (ISCED 3), were involved in active learning activities based on a flipped-up approach during specific online scientific events during the pandemic. Online lab activities were conducted during European Researchers’ Night (“ Earthquakes: history teaches us the future: researchers for a day with experimentation in didactics for ESL ”) and during both World Water Day 2021 and World Earth Day 2021 (“ Tsunamis: history teaches us the future researchers for a day with experimentation in didactics for ESL ”). These two Episodes of Situated Learning (ESL) experiences triggered students’ interest, favoring remote learning, developing life skills, and focusing on historical seismic studies of both past earthquakes and tsunamis.


Introduction
As Thucydides taught as early as the 5th century B.C., "One must know the past in order to understand the present and affect the future".The "past teaches the future" concept stands at the basis of Uniformitarianism, formulated by the geologists James Hutton and Charles Lyell, who summarized their understandings with the well-known slogan, "the present is the key to the past".More recently, Carl Sagan famously wrote, "You have to know the past to understand the present".The past and the future are not very different, and this concept is even truer concerning natural hazards.Indeed, if an area has been affected in the past by significant natural events (earthquakes, tsunamis, floods), similar events will certainly occur again in the future, because every natural past event has causes that continue to work in the same way.Likewise, each past event has implications for future ones, and, when a disaster event takes place, society is deeply transformed.As such, for a better understanding of the future, we must study the past with a critical approach.
The designed educational activities described in this paper have two main aims: (1) to demonstrate that a careful study of past earthquakes and tsunamis, on the basis of modern concepts, can offer a present-day understanding in order to infer events that may happen in the future; (2) to trigger critical thinking, stimulating reflection and increasing preparedness in response to earthquakes and tsunamis and thus strengthening resilience [1].
According to the "Hyogo Framework for Action 2005-2015: Building the Resilience of Nations and Communities to Disasters, International Strategy for Disaster Reduction and to the Chart of the Sendai Framework for Disaster Risk Reduction (2015-2030)", particularly in relation to Priority 1 (Understanding Disaster Risk), we aimed to substantially reduce the disaster risk and loss of lives for a more resilient society (UNISDR, 2015; https://www.preventionweb.net/files/44983_sendaiframeworkchart.pdf,accessed on 12 December 2023).The INGV activity addressed to schools was focused on the prevention of future natural events, favoring the reduction of hazard exposure and the vulnerability to disaster.
Since the introduction of the Episodes of Situated Learning (ESL) method in Italy by Prof. Rivoltella [2,3], the INGV has applied it to its research topics, in order to involve students by using technology at school [4].
Following the ESL methodology, complex scientific concepts are "divided" into small pieces of fundamental knowledge that students can acquire in order to transfer key concepts to their peers.Students' communication products, e.g., digital posters, are the creative results of their personal learning processes.ESL is structured in three phases: preparatory, operative and debriefing, and implementing the principles of flipped lessons [5].Researchers are not mere "dispensers of knowledge", but they are tutors in an assisted laboratory, acquiring significant observations and considerations through shared research and the reworking of learning by doing activities.
The need to design engaging and educational distance learning activities to support students and teachers during the COVID-19 pandemic led us to test the online use of this innovative digital teaching method, previously used only in person [6,7].
On the occasions of European Research Night 2020 and on both World Water and World Earth Day 2021, the distance lab activities "Earthquakes: history teaches us the future" and "Tsunamis: history teaches us the future" were performed by the INGV.The first ESL was tested within the NET Science Together project, and the second one was tested both within the European Interreg Italy-Croatia project called PMO-GATE and within the project Future Responsible Citizens (FCR)-Educational Paths of Civil and Environmental Responsibility, in collaboration with the Italian Associazione per lo Sviluppo Sostenibile e Centro di Educazione Ambientale (ASSOCEA Messina APS).
Approximately 2200 students from middle school third-year classes (13-year-old students) and from all classes of high school (14-to-18-year-old students) took part in our ESL experimentation.After the INGV researchers' explanatory lesson on past earthquakes and tsunamis, students became "researchers for a day" and prepared, independently, 150 creative digital artifacts describing some of the most important historical events in their region.Researchers' knowledge was at the service of the school, using a curiosity-driven approach in order to help homebound teachers and students during the pandemic.The activities were designed to increase the awareness of the risks related to earthquakes and tsunamis through the study of past events, bringing students closer to the world of research and encouraging them to independently develop content after a discussion with the experts.The main purpose was for them to understand how the past is an important key to reducing the impact of future events.At the end of this experiment, some students reported their experience in "Noi Magazine", the insert in Gazzetta del Sud dedicated to education.
At the end of each scientific event, different satisfaction questionnaires were distributed to both teachers and students.The feedback was very useful in assessing the perceptions and appreciation of our educational learning activities, and they encouraged us in the design of new ESLs.In addition, every teacher, every student, and all classes were handed a certificate of participation for the event.

Episodes of Situated Learning (ESL)
This paper intends to present a new didactic model based on the ESL method.ESL works on the minimum didactic unit, i.e., the barycenter from which the teacher's didactic action is developed.The structure of an ESL consists of a natural ternary that is related to the school setting's management [8].Each phase can be considered a stage in the learning process that corresponds to a type of teaching logic, as schematized in Figure 1.
action is developed.The structure of an ESL consists of a natural ternary that is related to the school setting's management [8].Each phase can be considered a stage in the learning process that corresponds to a type of teaching logic, as schematized in Figure 1.The three fundamental steps are always presented in sequence, but they are related to each other: (1) the anticipatory moment, which consists of a stimulus situation (conceptual framework, video, image, experience, document, testimony); (2) the operative moment, consisting of a micro-production activity (analysis/creation of a text starting from a problem to be solved); (3) the debriefing moment, which consists of restructuring what has been realized in the previous two steps [9].
Students design a communication product in a context that challenges their knowledge, skills, attitudes, and competences; on the other hand, teachers enforce learning and, thanks to this method, can evaluate all three phases of ESL activity to achieve a formative assessment.Indeed, the students' evaluation is, at the same time, evolutionary (it verifies the development of competences), comprehensive of the in itinere evaluation moments, and coherent with the actions carried out [10,11].
The ESL method has its origins in mobile learning and it has been widespread since the introduction of tablets in schools.It should be considered as an integrated approach to teaching.This model entails the radical redefinition of all three macro-actions into which teaching is divided: (1) planning, which is rethought in modular terms [12]; (2) communication, where the concept of "frontal lessons vs. active didactics" is overcome, focusing on problem solving and making and sharing new digital products, and ending with a collective reflection; (3) assessment, evolving towards the concept of new assessment, with particular attention to embedded and cumulative tasks [13].
The design of an ESL requires some fundamentals: selecting the microcontents, providing scaffolding, determining and supporting the role of the teacher, and assessing situated learning.This implies careful design work [14] rather than planning, with a perspective that could be defined as "assembling cultural objects" [15,16].
The didactics for ESL consist of finding simple solutions to complex phenomena, as exemplified by problem solving in a complex situated context.Applying a "simplex" strategy means striving for very advanced solutions, reducing the effort required to manage them.The "simplexity" neologism reflects a possible complementary relationship between complexity and simplicity, looking for simplicity through design [17,18].Thanks to Berthoz's theory of simplexity, the ESL method is found to be a significant learning experience with a strong cognitive transferability.Classrooms using the ESL method apply the The three fundamental steps are always presented in sequence, but they are related to each other: (1) the anticipatory moment, which consists of a stimulus situation (conceptual framework, video, image, experience, document, testimony); (2) the operative moment, consisting of a micro-production activity (analysis/creation of a text starting from a problem to be solved); (3) the debriefing moment, which consists of restructuring what has been realized in the previous two steps [9].

The ESL has a flipped-up teaching approach (at home, students obtain information; at school, they learn), which is quite different from a traditional lesson (at school, students learn concepts; at home, they study).Homework is for learning and the acquisition of new skills, while classwork is for reworking and understanding [20].
In the ESL method, the flipped classroom is integrated with cooperative learning, allowing one to reach the highest levels of Bloom's taxonomy, which, starting with the basis of Bloom's pyramid, is structured in the following way: - Students following the ESL method must progress through all the steps to be able to design a communication product that can explain to others the micro-content that they have reworked.
According to the European Commission's Recommendation 2006/962/CE regarding the Key Competences for Lifelong Learning, ESL is a methodological proposal for a "smart school" that trains students to be able to optimize their resources by developing problemsolving skills [22].The development of critical thinking is favored by the reflection necessary to carry out the assignment.Good critical thinkers are able to split a broad idea into many parts: they can examine each part, question biases, and come to a reasonable conclusion [23].

Experiments in Innovative Geosciences Education through ESL as Interactive Teaching Tools for Modern School
Applying the ESL methodology to geosciences requires an innovative system to involve both students and teachers in a new approach to teaching and learning, using simple digital tools to learn even complex concepts.This method is also very successful in activities addressed to schools, aimed at reducing natural hazards and teaching good practices for civil protection purposes.Our first ESL experiment produced comics on safe behavior in the case of natural events.Then, within the framework of the KnowRisk (Know your city, Reduce seISmic risKthrough non-structural elements) project, the ESL's final digital outputs were creative products dedicated to non-structural seismic risk reduction [24][25][26][27][28]. Another ESL, titled "A nuoto tra i vulcani Italiani" ("Swimming among the Italian volcanoes"), developed to raise awareness of the ESL method among teachers, was designed to explain Italian seamounts using interactive maps.This latter ESL was also used on the occasion of the European Researchers' Night 2019, held in person in Pisa within the framework of the Bright project.
On the basis of our previous experience, during the COVID-19 pandemic, we created some ESLs whose final products were interactive maps to be discussed online during the debriefing phase via distance learning.Moreover, since topics related to macroseismic studies had to be dealt with, producing interactive maps as a digital output was the most suitable tool to approach this type of research.
In order to teach students that the past is fundamental to understand the present for a better future, not only in history but also in geophysics, we developed a learning activity that involves encouraging them to work as geophysicists.We therefore used the study of past seismic and tsunamigenic events to engage students in a self-made exercise in which they were involved directly, working in groups, experimenting with new digital techniques, and presenting their results to others as researchers do at scientific conferences [29][30][31]  The first ESL designed during the COVID-19 pandemic was "Earthquakes: history teaches us the future", addressed to students from middle school third-year classes (ISCDE2) and from all classes of high school (ISCDE3).Within the framework of the NET Science Together project (a Marie Curie project funded by the European Commission), the ESL activity was performed during a special edition of the European Researchers' Night 2020, held exclusively online for schools, in the week of 23-27 November during the COVID-19 pandemic.
The "Earthquakes: history teaches us the future-researchers for a day with experimentation in didactics for ESL" special event was structured into two live streaming sessions.During the first one, which occurred on 23 November, the INGV researchers explained the method to the students and teachers and they conducted a short preparatory lesson on the key concepts of earthquakes.In particular, this covered the definition of earthquakes and seismic waves, the distinction between microseismology and macroseismology, the difference between magnitude and intensity, and the tools and safe behaviors to adopt for risk prevention and self-protection.The researchers also underlined the importance of knowing about past earthquakes and they explained how scientists work to reconstruct their effects.This was a fundamental step because the students' task was to choose a historical earthquake of their interest and to study it as if they were true researchers.The students were asked to create an effective communication product addressed to their peers.To steer students in their work, they were provided with video stimulus, a list of earthquakes to choose from, a link to the CPTI15 historical seismicity database [32], and the Mercalli macroseismic scale.These students, working in cooperative learning, were divided into different groups in each class.The researcher selected, for each region, a list of the most significant earthquakes from the CFTI15 database.Each group of students, after choosing an earthquake from the list, searched for additional detailed information about the event, assigning a macroseismic intensity value to each locality involved.As a final product, they had to prepare a digital interactive intensity map of the chosen earthquake with linked multimedia files.They had also to provide the seismic history of the studied region, starting from the list of earthquakes supplied by the researchers and integrating it with the data extracted from the CFTI15 database (see Figure 2).This event was attended by a total of 464 students and 18 teachers from 23 classrooms throughout Italy.In particular, 204 students were from 10 middle school classes, producing 20 macroseismic interactive digital maps, while 260 high school students from 13 classes produced 38 interactive digital macroseismic maps.In one day, the researchers corrected the 58 interactive products, realized by using the ThingLink free app (see Table 1).Over the following two days, the INGV researchers supported the classes during their creative work phase.

The Earthquakes: history teaches us the future ESL is summarized in Table 2. Students from third class of middle school (ISCED 3) and first to fifth classes of high school (ISCED 4), dealing with the study of earthquakes

Skills that the ESL aimed to develop in students
Control and adaptability/complex dimensions/transferability Ability to represent identified relationships Ability to use groups of information for a personal representation of the topic Ability to use digital tools to visualize the distribution of tsunami effects on the coast Ability to produce information Ability to use technology in a goal-oriented way Ability to produce a creative cultural object (interactive map) What will the student be able to do at the end of this ESL?
The aim was to bring young people closer to the world of research, fostering the personal investigation of the topics discussed with the experts and enabling an understanding of how the past is an important key to reduce the impacts of future earthquakes.Through this experience, the students could understand that macroseismic study is fundamental in seismology and to reconstruct the seismic history of an area is a very complex task.The knowledge of the seismic and tsunamigenic history of a place is the result of meticulous and in-depth work, including the analysis of catalogues and historical documents.The ESL was performed at the end of the learning unit on seismic risk.Starting from basic geological-geophysical knowledge (notions of earthquakes, differences between magnitude and intensity, seismic hazards, macroseismic maps), the students learned that earthquakes are not predictable and the past can teach us about the future.

PHASES DESIGN
App TIMES -what earthquakes are and why we study historical ones; -the strongest earthquakes in Italy; -the difference between magnitude and intensity; -intensity assessment; -macroseismic maps.
Students studied these notions.
The aim was to elicit students' curiosity and enthusiasm about the historical seismology of our country, developing an awareness that the Italian territory has high seismicity and that earthquakes recur cyclically.Create with ThingLink an interactive intensity map (macroseismic map) of the chosen earthquake, with any geographical base.Consult the CFTI15 catalogue to obtain the information needed to construct the map.Enrich the digital map with additional information on the chosen earthquake (parts of original texts with damage descriptions, historical images, maps, etc.) (you can use the Internet for material).
(The final product was realized by small groups of 4-5 students, in order to have, at the end, a collection of interactive maps representative of the Italian territory.They could underline the importance of macroseismic studies to be emphasized in the debriefing).Each group of students placed the final product into a folder in Dropbox/Drive so that the shared document allowed for the immediate discussion of the results.

Assessment and Discussion
The teacher critically analyzed the output of the students, selecting a few intensity maps and asking the students to present them and explain the reasons for their choices; the teacher corrected the final products, made suggestions, and actively participated in the collective discussion, clarifying the appropriate conclusions, highlighting what is most important, and clarifying misconceptions about earthquakes.
The students analyzed the results and they reflected on their own final products and those of their peers, making observations.Metacognitive thinking was developed, resulting from the discussion with others about their final products and the way in which they were carried out.

Output
Corrected digital works could be shared and posted in the Dropbox/Drive folder.Each ESL must be supplemented by an assessment rubric, which is a summary of statements describing a competence, indicating the degree of achievement of the fixed objectives; in addition, a declination of competences grid helps teachers in evaluating the students involved in the ESL activities.In our case, both the assessment rubric and the declination of competences grid were the same for both the "Earthquakes: history teaches us the future" and the "Tsunamis: history teaches us the future" ESLs (see Tables 3 and 4).A further area in which we experimented in the "Earthquakes: history teaches us the future-researchers for a day with experimentation in didactics for ESL" event was a Path for Transversal Skills and Orientation (PTSO) pathway in a Scientific Lyceum in Pavia, within the framework of "Taramelli's Year".The project involved 34 students, from the fourth and fifth classes, who were divided into eight working groups, participating with great interest.Six 2-h online meetings with the students were held by INGV researchers in collaboration with the University of Pavia.Regarding the other ESLs, during the first meeting, the method was explained and the key concepts of earthquakes were introduced.Each group chose an event to be studied and had to produce a digital macroseismic map of the selected earthquake.The other online meetings were used to check the state of the art of the activity and to clarify students' doubts.Meanwhile, since the COVID-19 pandemic restrictions had been reduced, it was decided that each working group would present the results of their work to students of other classes in their school, during a ceremony held in person in the Lyceum's auditorium in May 2022.

Declination of competences grid
Another initiative was carried out within the framework of the "Taramellian Year", organized by the University of Pavia in collaboration with the INGV.In this activity, the learners were teachers, attending a 10-h training course titled "Teaching for ESL-Earthquake: history teaches us".The course was developed in four meetings held online from April to May 2022, and a specific lecture on the ESL method was held by Prof. Rivoltella.

Tsunamis: History Teaches Us the Future-Researchers for a Day with Experimentation in Didactics for ESL
The enthusiastic feedback received from both the teachers and students participating in "Earthquakes: history teaches us the future-researchers for a day with experimentation in didactics for ESL" led us to design a similar ESL dealing with tsunamis: "Tsunamis: history teaches us the future-researchers for a day with experimentation in didactics for ESL".This online learning activity was aimed at reconstructing past tsunamis within the framework of the PMO-GATE project, in which the INGV is involved in the study of tsunamis and meteotsunamis for the prevention of natural hazards, and within the framework of the FCR project, in which the INGV is involved in CON.I.RI.(CONvivere con I Rischi naturali-Living with natural hazards).This latter collaboration led to an interaction with the daily newspaper La Gazzetta del Sud-in particular, with its supplement, Noi Magazine, edited by high school students from Calabria and Sicily.This is why we decided to involve only middle and high schools from Sicily and Calabria in this ESL experiment.
On the basis of our experience in the ESL on historical earthquakes, we gave students more time to design their digital maps, exploiting the opportunities provided by two important events: World Water Day (22nd March) and World Earth Day (22nd April).The first live streaming session was held by the INGV researchers on the occasion of World Water Day 2021, to explain the ESL method and to raise awareness about tsunamis, a natural phenomenon whose risk on the Italian coast is very often underestimated.At the same time, during the lesson, the fundamentals of tsunamis were introduced: the definition of tsunamis, why and how past tsunamis are studied, the tsunami intensity scale, and the most relevant tsunamis in the Mediterranean Sea and, particularly, along the Italian coast.In addition, it was explained how to reconstruct the tsunamigenic history of a locality/area of interest.
The ESL activity was focused on the tsunami following the 1908 Messina (Sicily, Italy) earthquake, the strongest that has ever occurred in Italy.For this event, the students had to reconstruct the effects produced in the territory near their school.
"Tsunamis: history teaches us the future-researchers for a day with experimentation in didactics for ESL" was attended by a total of 1707 students and 43 teachers from 107 classrooms in Sicily and Calabria.In particular, approximately 900 students were from 60 classes in middle school, producing 75 macroseismic interactive digital maps, while, among all high school classes, approximately 800 students from 47 classes produced 90 interactive digital macroseismic maps (see Figure 3).

The Tsunamis: history teaches us the future ESL scheme is summarized in Table 6.Due to the large number of participants in the special event concerning the earthquake ESL described in Section 2.2.1, it was difficult to manage the timing of the final live debriefing day.Indeed, it was necessary to give voice to all 58 groups of students who had presented their products to their peers and discussed them with the researchers.Students from third class of middle school (ISCED 3) and first to fifth classes of high school (ISCED 4), dealing with the study of tsunamis Skills that the ESL aims to develop in students Control and adaptability/complex dimensions/transferability Ability to represent identified relationships Ability to use groups of information for a personal representation of the topic Ability to use digital tools to visualize the distribution of a tsunami's effects on the coast Ability to produce information Ability to use technology in a goal-oriented way Ability to produce a creative cultural object (interactive map) What will the student be able to do at the end of this EAS?
The aim was to bring young people closer to the world of research, fostering a personal investigation of the topics discussed with the experts and enabling an understanding of how the past is an important key to reduce the impacts of future tsunamis.Through this experience, the students could understand that tsunamis are closely related to earthquakes and that, even for tsunamis, events that occurred in the past can be repeated in the future with similar characteristics.Reconstructing the effects of tsunamis is often difficult because tsunami damage is added to that caused by the generating earthquake.The knowledge of the seismic and tsunamigenic history of a place is the result of meticulous and in-depth work, including the analysis of catalogues and historical documents.In particular, the case study of the tsunami associated with the Messina earthquake of 1908 was analyzed.The ESL was performed at the end of the learning unit on tsunami risk.Starting from basic geological-geophysical knowledge (notions of earthquakes and tsunamis, seismic and tsunami hazard maps, tsunami intensity assessment), the students learned that, even for tsunamis, the past can teach us about the future and that tsunami warning systems exist for risk reduction.

Framework
At school, the teacher described the key concepts of tsunamis with a Powerpoint presentation: -what tsunamis are and why we study historical ones; -the strongest tsunamis in the world and in Italy; -the Messina tsunami of 1908; -tsunami intensity assessment; -a map with the distribution of tsunami effects.Students studied these notions.
The aim was to teach students that, even in our country, tsunamis represent a real, often underestimated risk for coastlines.Visualize, for the chosen locations, the tsunamigenic history, redrawing it and inserting it into your map, correlated with the relevant information obtained from the tsunami intensity scale provided.
(The final product was realized by small groups of 4-5 students, in order to have, at the end, a collection of interactive maps representative of the entire Sicilian and Calabrian coast.They could underline the importance of the tsunami phenomenon in the area, to be emphasized in the debriefing).Each group of students placed the final product into a folder in Drive so that the shared document allowed for the immediate discussion of the results.
ThingLink (for interactive maps) Word processor (for the tsunamigenic history diagram) DRIVE (for the final product) 60 ′ 15 ′

DEBRIEFING PHASE Assessment and Discussion
The teacher critically analyzed the output of the students, selecting a few tsunamigenic maps and asking the students to present them, explaining the reasons for their choices; the teacher corrected the final products, made suggestions, and actively participated in the collective discussion, clarifying the appropriate conclusions, highlighting what was most important, and clarifying misconceptions about tsunamis.
The students analyzed the results and they reflected on their own final products and those of their peers, making observations on the different products.
Metacognitive thinking was developed, resulting from the discussion with others about their final products and the way in which it was carried out.

Output
Corrected digital works could be shared and posted in the Drive folder.
Notepad (to write conclusions) DRIVE (to archive the final report) 30' In response to the huge number of participants in the tsunami ESL, the number of sessions for the second live streaming event on the occasion of World Earth Day 2021 was doubled, separating the students from the 60 middle school classes and the students from the 47 high school classes.Therefore, the INGV researchers conducted two second live streaming events dedicated to the debriefing phase on 22nd April 2021, in which the researchers and students discussed the results obtained for a constructive comparison and exchange of experiences among the participating classes.

Results
In the context of fast socio-cultural transformation, teaching must adapt, embracing the new educational needs through new means of engagement and learning towards a positive outcome.This need was particularly evident during the COVID-19 pandemic, when it was necessary to combine the traditional in-person classroom method with e-learning [33].Some activities that usually took place in the classroom were performed online by means of mobile systems (smartphones, tablets).Indeed, technology played a very important role, not only in supporting in-person lessons but also in favoring interaction remotely and in providing online resources [34].In this particular historical period, it was necessary to explore new means of using digital teaching methodologies, such as ESL.This method, based on the flipped class model, has a teaching approach that focuses on emotional, cognitive, and behavioral components.The students autonomously acquire new information at home; then, with their teachers and schoolmates, they rework, share, and discuss their assignments [35].Our experience in using the ESL method applied to geosciences at schools highlighted that this approach is an effective tool to enhance motivation and learning, developing positive emotions and favoring higher levels of self-efficacy [36,37].This is an opportunity to train students' skills in an active and participative environment.The low level of perceived anxiety in students also improves their learning [38].Indeed, this method works in a real-life context, in which learning occurs in everyday situations and not only in dedicated teaching environments.The didactic becomes more experiential and reflective, providing meaningful learning.This context improves the teacher-student relationship and grants teachers the necessary conditions to achieve an effective and authentic assessment, observing students during all three phases of ESL [39].
To celebrate 10 years of the method, the Catholic University of Brescia organized the "ESL Day", titled "Gli EAS tra didattica e pedagogia di scuola-10 anni di metodo" ("ESL between didactic and school pedagogy-10 years of the method").On this occasion, we were invited by Prof. Rivoltella to present a lecture on our ESL experiments in the earth science disciplines, as we were pioneers in the application of the method in teaching geosciences and geophysics.
The sharing of the experiences of students from across Italy, during a period in which the entire population was homebound due to the COVID-19 pandemic, was the main strength of the activity.
Concerning "Earthquakes: history teaches us the future-researchers for a day with experimentation in didactics for ESL", we collected many warm and enthusiastic comments of gratitude from the students as they felt part of a community, able to learn in an active and cooperative manner.Among the many testimonies of satisfaction, the most notable ones from high school students were as follows.
"An interesting and useful project on a subject about which people are often misinformed and underestimate the risks.It gave us the opportunity to learn how to reduce natural hazards".
"We were able to learn new and interesting topics, and at the same time we learnt how to work together in the most effective and efficient way".
"This activity allowed us to know earthquakes in a different way from the scholastic one, certainly more engaging, giving us a creative stimulus.I was fascinated to learn how a historical seismologist works".
"This project was really interesting both because it was different from all the others, and because of its practical approach.We used new digital tools to manage earthquake data working in teams.It was fun and made the work less burdensome, even dealing with a very delicate subject.I hope to do similar activities soon".
In addition, numerous appreciative e-mails were received from the teachers involved in the activity.Similarly, this positive trend was highlighted by the answers to the questionnaires distributed to the students and teachers after the learning activity.
Moreover, regarding "Tsunamis: history teaches us the future-researchers for a day with experimentation in didactics for ESL", we collected many very appreciative posts from the participating schools and reports in Noi Magazine, a supplement of La Gazzetta del Sud dedicated to education.In the related TGweb, the students reported about their experiences like "little journalists".The following are two of the most significant comments received from teachers: "It was a stimulating and engaging initiative that let the students be protagonists and induced them to ask questions and look for answers, as researchers do".
"A fruitful and exciting activity that puts students at the center of their learning process, making them the protagonists of their own education.An opportunity to experience a conscious and responsible use of new technologies".
At the end of each ESL activity, a survey was conducted by providing a satisfaction questionnaire, which was different for teachers and students.The feedback was very useful in assessing the perceptions and appreciation of our educational proposal and they guided us in the design of new learning activities.The answers received, in fact, confirmed the appreciation and interest of both students and teachers.The following figures (Figures 4-9) show the results of the satisfaction questionnaires administered.Concerning the importance of the collaboration between schools and researchers, in general, the teachers answered the questionnaire with a higher degree of positivity than the students.The students seemed to be less impressed by the projects than the teachers, but if we combine the answers describing the initiatives as "very interesting" with those describing them as "interesting", this accounts for 87 percent of the respondents.Nonetheless, twenty years of experience with this type of initiative in schools has shown that students generally do not enjoy completing satisfaction questionnaires at the end of an activity.In fact, much less feedback is typically collected compared to the number of participating students.
The ESLs tested during the COVID-19 pandemic allowed us to reach a very high number of students and teachers simultaneously connected on the internet, improving the interaction between schools and researchers during this difficult period.The encouraging feedback received on the satisfaction questionnaires from all participants proves the educational efficacy of the designed ESLs.

Within the framework of the 90th Congress of the Italian Geological Society "Geology Without Borders", held online in September 2021, a talk titled "Experiments of e-learning: ESL (Episodes of Situated Learning) during the Pandemic" was presented.As a result of this presentation, the University of Pavia permitted us to experiment with didactics for ESL within the Path for Transversal Skills and Orientation (PTSO).The activity was conducted through distance learning during the first two phases, while the debriefing phase was held in person.The resulting blended (or hybrid) learning was an integrated teacher (in this case, researcher)/learner approach strategy in a combination of different learning environments [40].
Future developments include the design of new ESLs on scientific topics, both in the field of earth sciences and geophysics and in environmental issues, such as one realized by request for the Geothermix 2023 conference.This ESL dealt with geothermics in Italy and a ThingLink interactive map was presented within the keynote speech titled "Experiments in innovative Geosciences Education through Episodes of Situated Learning (EAS) as interactive teaching tools for modern School: the case of Geothermal and Geo-resources", presented at the Geothermix 2023 conference held in Pisa in November 2023.

Discussion
An ESL is a "simplex" strategy, creating connections between real life and didactics, helping students to find simple tools to aid their learning and cope with complexity and to develop students' skills by means of devices [41].The term "simplexity" originates from the biological strategies through which living species adapt themselves to the surrounding complexity.The solutions to deal with different situations consider past experiences and anticipate future ones; these are new means of addressing problems so that actions may be taken quickly and efficiently [42].The philosophy behind ESL is "say a lot in a few words and, if possible, make people think more than they say" [43], triggering a process to simplify various principles for a complex world.
According to Howard Gardner's theory of multiple intelligences [44,45], humans do not have only one intellectual capacity, but they have many types of intelligence that fulfill eight criteria: visual-spatial, linguistic-verbal, logical-mathematical, body-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic.Many teachers use multiple intelligences in their teaching to integrate Gardner's theory into the classroom.In relation to this, one of the strengths of the ESL method is the development of active learning in which students are free to express all their abilities [46].Another of the most relevant benefits of the ESL method is that it allows the student to use his/her own intelligence with respect for all identities [47].Each student might demonstrate specific strengths and abilities, so that, in a classroom, a wide range of different talents is available [48].These are the reasons for which ESL is an appealing didactic method that could be performed worldwide to favor a modern school approach.
ESL is a methodology that is particularly suitable for the study of natural hazards in order to promote the spread of good practices, fostering the development of emotional intelligence, which is key to well-being, when the right and left parts of the brain are in equilibrium.Daniel Goleman describes emotional intelligence as an ability to understand and manage one's own emotions and influence the emotions of others [49].Examining the interpersonal and intrapersonal aspects, human intelligence is deeply linked to the social and affective dimensions of human life.ESL is a didactic methodology that is able to put into practice this creativity found between rational and emotional thinking.Thanks to this creativity, students can learn spontaneously in a friendly environment.The advantages of flipping are to promote peer interaction and collaboration skills, to make learning central rather than teaching, to foster independent learning, to encourage stronger student engagement, and to provide increased individualized attention [50].
The ESLs developed during online meetings with the INGV researchers (informal learning) focused on microlearning activities to achieve self-production, starting from real life (knowing the seismological setting of the student's own area, which is a crucial factor in seismic hazard reduction).This is placed within the context of gathering together knowledge, skills, attitudes, and competences.Students learn more effectively if they start from situations of daily life or in their territory, in which they can focus their attention, acting based on microcontent and developing their thinking skills, problem solving, and reflective learning [51].The situated education action as a minimum but significant unit is a clear example of how it is possible for teachers to work with ESL in the virtual classroom with students at home, connected by the internet and not only in person [52].

Conclusions
ESL proposes an innovative means of studying with the use of new technologies, as a new method of teaching and learning.Our experience with ESL with 13-18-year-old students shows that a good lesson plan for this method can foster the development of critical thinking.The activities are designed to support authentic language use and to develop a type of thinking that involves making fair, careful judgements and evaluations based on evidence, reason, reflection, and open-mindedness.In brief, ESL involves teaching learners to analyze complex settings [53].Students have to understand the core problem and suggest solutions through the creative assembly of cultural objects [54].In order to create a digital communication product for their peers, the students must acquire the ability to focus on the key concepts of the studied topic, reworking and understanding them in a more comprehensive manner.An example is the ESL named "Earthquakes: history teaches us the future: researchers for a day with experimentation in didactics for ESL", in which the students discovered the differences between microseismology (analysis of seismic signals) and macroseismology (damage estimation).Under the guidance of the researchers, the students understood how multi-faceted seismologists' work is: it can deal with different branches of seismology, studying the various aspects of earthquakes for a greater understanding of the Earth system as a whole.During the second phase of the ESL, to enrich the final macroseismic map with further information about the chosen earthquake, the students searched the internet and analyzed parts of original texts describing the earthquake's effects, as well as images and historical maps.In this way, they were able to identify themselves in the work of the historical seismologist, performing an engaging educational activity.
The ESL model leads to higher levels of scholastic engagement in students and reduces their levels of perceived anxiety.Moreover, this method facilitates embedded assessment activities, thanks to assignments and exercises focused on a particular learning outcome.Indeed, the evaluation is formative: it is not only a score for the students' final digital creative product, but it is the result of the teacher's observation during all three ESL phases.The assessment encompasses the behavior of the student, who, independently and in groups, works on a project and then presents its product to others.The teacher can evaluate the student's work, using an assessment rubric, designed as an ad hoc summary statement describing their competences and indicating the degree of achievement of the set objects.The synthetic outlines of the declination of competences grid provide a further detailed evaluative tool that forms an objective evaluation criterion, pointing out which parameters are to be considered in the evaluation.This type of evaluation allows teachers to identify students' skills within a particular domain (e.g., social, academic), favoring future lesson plans to support each student's progress [55].Moreover, it enables them to discover whether the designed learning activity is effective.ESL needs a carefully designed lesson plan to create situated and meaningful learning experiences, leading students to realize digital artifacts and fostering the personal appropriation of content.The effort of finding suitable video stimuli and learning trigger activities requires a lot of time and sometimes discourages teachers, who have to search the internet to design creative activities through free apps, addressing students' self-production activities [56].Therefore, teachers particularly appreciate the availability of ready-to-use ESLs on topics of their interest to implement in their classes.In this case, the teachers do not need to have extensive knowledge of the method or particular expertise to apply it.They only have to follow the exercise step by step.
The ESL experiments of the series "History teaches us the future: researchers for a day with experimentation in didactics for ESL" are two examples of the digital teaching of geoscience, created to help students and teachers during the COVID-19 pandemic.They are perfectly aligned with the INGV's mission to distribute geophysics research results.This activity is not merely dissemination and communication: it is education [57].It is also a means to bring future responsible citizens closer to researchers' work and to make students aware that public research is at the service of society.Researchers and schools can achieve a great deal together, focusing on protection, knowledge, and awareness of natural disaster prevention, and they can encourage good practices and safe and sustainable behavior [58][59][60].This is a means to build resilience at school, involving students, teachers, school leaders, and families too, because children can be a valuable vehicle by which to increase awareness among adults [61].
