Virtual Archaeology is defined as ‘the scientific discipline that seeks to research and develop ways of using computer-based visualizations for the comprehensive management of archaeological heritage’. In essence, it involves the creation of virtual models of various types whose purpose is to represent elements of the past based on historical data obtained from research. It is a discipline that has experienced a boom in recent years, thanks to the democratization of both technology and training, and has become one of the most fruitful branches of what is known as Digital Humanities. However, despite its name, it has applications beyond the field of archaeology, notably in Art History. In this sense, it allows recovering the original likeness of lost or altered works, the formulation of research hypotheses, or the generation of resources with great didactic and dissemination potential. This study aims to offer an overview of the fundamentals of the discipline and explore the possibilities it offers to Medieval Art History. Furthermore, this study serves as a starting point for new projects. Full article

Salvation through Refinement (liandu 鍊度) is a distinctive Daoist rite aimed at rescuing the souls of the deceased from hell, enabling their rebirth, and ultimately facilitating their transcendence. The Golden Writings on the Great Achievement of Deliverance by the Numinous Treasure of Highest Clarity (Shangqing Lingbao Jidu Dacheng Jinshu 上清靈寶濟度大成金書), compiled by Zhou Side 周思得 (1359–1451), preserves a wealth of material related to Salvation through Refinement. This content can be divided into two parts: the ritual procedures of Salvation through Refinement and the associated internal practices (neishi 内事). Zhou explicitly stated that the Salvation through Refinement ritual originated from the Golden Book of Salvation according to the Lingbao Tradition (Lingbao Lingjiao Jidu Jinshu 靈寶領教濟度金書), compiled by Lin Lingzhen 林靈真 (1239–1302), whereas the internal practices are not attributed to any specific source. Comparative analysis confirms that the section on internal practices derives from the Brief Discussions of Inner Method of Taiji for Sacrificing to and Sublimating [the Souls of the Deceased] (Taiji Jilian Neifa Yilüe 太極祭鍊內法議略), compiled by Zheng Sixiao 鄭思肖 (1241–1318). Zheng Sixiao’s Salvation through Refinement method centers on Visualization and Actualization (cunxiang 存想), with the entire process taking place internally within the ritual master’s body. Building upon this foundation, Zhou Side incorporated additional ritualized actions and recitations, striving to integrate external ritual with internal practice. In doing so, he constructed a model of Salvation through Refinement characterized by the union of inner methods and outer rites. Inner Sublimation emerged during the Southern Song period, likely influenced in both principle and method by the then-prevalent School of the Mind (xinxue 心學). It sought to counter the increasing complexity of ritual practices at that time. Meanwhile, the continued practice of traditional forms of Retreats (zhai 齋) and Offerings (jiao 醮) reflected the Ming (1368–1644) rulers’ emphasis on the didactic function of such rituals. In his compilation, Zhou cited the views and materials of others under the name of Tian Sizhen 田思真 (fl. early 12th century) to articulate the inner meanings and core doctrines of the Numinous Treasure (lingbao 靈寶) rites. By positioning Tian Sizhen as an intermediary, Zhou not only established a line of transmission between the rites he compiled and the orthodox Numinous Treasure lineage represented by Lu Xiujing 陸修靜 (406–477) but also affirmed his conscious identification with the Daoist ritual tradition and his stance regarding its lineage.

The growth in the number of students in higher education institutions (HEIs) in Latin America reached 33.5 million in 2021 and more than 220 million worldwide, increasing the number of data volumes in academic management systems. Some of the difficulties that universities face are providing high-quality education to students and developing systems to evaluate the performance of teachers, which encourages offering a better quality of teaching in universities; in this sense, machine learning emerges with great potential in education. This literature review aims to analyze the factors, machine learning algorithms, challenges, and limitations most used to evaluate the quality of teaching based on performance. The methodology used is PRISMA, which considers analyzing literature produced between 2014 and 2024 on factors, prediction algorithms, challenges, and limitations to predict the quality of teaching. Here, 54 articles from journals indexed in the Web of Science and Scopus databases were selected, and 111 factors were identified and categorized into five dimensions: teacher attitude, teaching method, didactic content, teaching effect, and teacher achievements. Regarding the advances in machine learning in predicting teacher teaching quality, 30 ML algorithms were identified, the most used being the Back Propagation (BP) neural network and support vector machines (SVM). The challenges and limitations identified in 14 studies related to HEIs are managing the large volume of data and how to use it to improve the quality of education. Full article

Citizen science resources have had great relevance in community educational intervention, fostering interest in ecological research projects. This study investigated the influence of the application of multimedia didactic resources focused on citizen science and analysis of sociodemographic variables to improve the levels of ecological knowledge about mosquito-borne diseases. For this, a probabilistic sample of 172 participants from an urban sector in southwestern Colombia was selected. A multimedia didactic material was designed for the educational intervention and evaluated by means of pretest and posttest. To assess whether the educational intervention was statistically significant, the data were processed with statistical inference to determine the influence of various variables (gender, age, marital status, schooling, and occupation) on each person’s ecological knowledge. The findings showed a significant increase in the knowledge levels of the participants. The marital status variable (married and cohabiting) significantly influenced ecological knowledge. These participants are more likely to obtain high knowledge, associated with the prevention of their family environment. This study demonstrated that multimedia didactic strategies are an important factor to take into account in the structuring of environmental education and citizen science projects. For future research, it is suggested to deepen the relationship between sociodemographic variables and ecological knowledge. Full article

Extended reality, which encompasses virtual, augmented, and mixed reality, emerges as an important didactic resource, offering great potential to bring heritage closer to the educational environment. Heritage education is a challenge for today’s society, contributing to cultural and social development. Therefore, the aim of this systematic review is to analyze documents related to heritage in education through extended reality. The search was conducted using Scopus and Web of Sciences databases, allowing for an international search. We excluded any document that was not a scientific article published in a journal. A total of 52 documents were analyzed, all of which were open-access articles. Preliminary results indicate that virtual reality and augmented reality are utilized in education to work with architectural, historical, archaeological, and musical heritage. Extended reality has been applied in all the stages of the education system, and in formal and non-formal settings, thereby demonstrating its versatility. These experiences increase motivation and academic performance in comparison to less innovative methodologies, which is in line with other studies on this topic. In conclusion, extended reality has the potential to make a significant impact on education, particularly when combined with heritage. The creation of multidisciplinary groups will enhance research in the near future. Full article

The approach to the personal experiences and previous ideas about physical education of future primary education teachers is a starting point of great interest for the teaching of the subject of physical education didactics. The aim of the study is to investigate these prior beliefs and to verify to what extent this initial perception changes after taking the “Didactics of Physical Education” course. A concurrent mixed-methods study was conducted, which included two data collection procedures: (1) a pre-experimental design with a single group featuring a pre-test and post-test; (2) the analysis of students’ autobiographical accounts of their experiences with physical education in school. The participants were students enrolled in the Bachelor’s degree program in primary education at the University of Santiago de Compostela (USC) who undertook the course in 2022–2023. The results obtained reveal that after taking the Didactics of Physical Education course, students gave greater value to more positive concepts of learning, socializing, participating, and playing, among others. Similarly, in the post-test, the assessment of concepts such as competitiveness and physical fatigue diminished. In their autobiographical accounts, students associated good memories with relationships with classmates and the playful socializing nature of the subject; among the bad memories, they highlight the content related to physical performance, competitiveness, and lack of attention to the diversity of students and their individual characteristics.

Mediterranean areas contain a great diversity of flora and phytocenosis, due to the different substrates and the special Mediterranean climate, and it is in the Iberian Peninsula where the greatest diversity is concentrated. The need for didactic techniques that generate awareness and good learning results is considered of great relevance in order to obtain well-trained environmental managers. We proceed to the research on different phytosociological groups. The one with the largest number of associations or plant communities is the one located in nitrified environments near urban areas; the group of communities dominated by Poa bulbosa is of great interest for sheep farming, while, for equine and bovine farming, the communities rich in grasses and legumes that are located in rural environments rich in organic matter are of interest. The latter communities are also interesting because they act as a sink for CO₂. Due to the serious alterations in Mediterranean grasslands, we propose cultural, socio-educational, and socio-economic strategies to increase family income, thus avoiding the south–north migratory flow, as well as combining exploitation and conservation, and promoting sustainable development.

The rapid evolution of university education is accompanied by a multitude of very specific, but rarely interrelated, research. The importance of socialization, informal learning, virtuality, flexible furniture, and learning by doing are recurrent themes, but they are often analyzed in isolation. The great potential for understanding these concepts lies in the value of their gradients, thresholds, interstices, interconnections, and the multiple relationships between them. Interrelating the existing analyses defines the learning ecosystem where thresholds acquire didactic prominence. Since the beginning of this century, radical changes have been taking place in the way learning is understood and are accompanied by regulatory changes (e.g., the Bologna Plan), methodological shifts, and spatial changes. Teaching innovation and spatial innovation mutually enhance each other in the search for teaching quality. In this research work, the state of the art is organized and classified into five assumptions, each with a graphic analysis, so that different architectural styles, geographical locations, and periods are represented, all with didactic potentials. The result comprises five design criteria proposed to build the different gradients of each hybridization. Full article

Heritage plays a significant role in understanding historical societies, particularly intangible heritage, as a legacy kept “alive” solely by the action of communities. Therefore, it holds great education potential in the context of critical citizenship education. This action research aims to investigate the perceptions of primary education teachers about intangible heritage and its didactic potential in critical citizenship education. In addition, this paper analyses the changes and continuities that occur in student teachers’ perceptions after carrying out a didactic project focused on relevant social problems linked to the Way of Saint James. This case study is proposed for primary teachers in initial training at the University of A Coruña (Galicia, Spain). The study was conducted during three academic years (2020–2023), with the participation of 160 student teachers. The questionnaire, the interview, and the focus group were used as research instruments. Students learned to give more importance to understanding intangible heritage and reconsidered it as an educational resource for critical citizenship education. However, many aspects of a traditional heritage education remain, where what matters is to respect and care for what is inherited without questioning its current value or its suitability for transmission to future generations.

Geoheritage constitutes a natural resource that promotes sustainable rural tourism by creating employment and activities that allow population settlement in unpopulated areas with great natural heritage. The objective of this work is to value the singularity and variety of the geosites, which show a wide geodiversity, with lithological, geomorphological, tectonic and natural process diversity (fluvial, coastal, sedimentary, etc.). In the “Arosa estuary” (Galicia, Spain), seven Geosites have been identified, described and valued, determining their scientific, educational and tourist-recreational potential and obtaining values between 565 and 660 points. The state of conservation and risk of degradation is analyzed in order to proceed with their geoconservation, promoting sustainable geo-tourism. The values of degradation susceptibility range between 0.03 and 3 points, and anthropic degradation between 0.33 and 1.73 points. A 3D virtual itinerary is made using Google Earth, implementing descriptive sheets, interpreted diagrams and photographs, and analysis of the geological processes. An interactive virtual flight is presented for academic and tourist purposes to promote geotourism. The virtual tour also has geomatic didactic elements: geoapp and georeferenced thematic cartographies. These resources are helpful for the unknown geoheritage of the population that lives or visits the “Arosa estuary”, favoring sustainable development and fostering attitudes and skills of respect for nature.

Miracle tales are didactic stories related to Buddhist figures, objects, and places that describe supernormal occurrences brought about by acts of great piety and fervent devotion. They present the audience with concrete examples of the workings of karma, while simultaneously setting verifiable historical precedents in a bid to prove the religious efficacy of Buddhism in China. These were also historiographical works, providing a wealth of detail regarding not only religious life and belief in China, but also local lore, politics, architectural trends, and much more. This paper will focus on a text called the Ji shenzhou sanbao gantong lu 集神州三寶感通錄 (T2106), a collection of miracle tales compiled by the seventh-century scholar-monk, Daoxuan 道宣 (596–667 CE). This text is a collection of narratives drawn from literary and epigraphy sources, as well as orally transmitted stories. As a Buddhist figurehead and as the author of many seminal historiographical works, Daoxuan played a central role in the overall localization of this tradition in China. Bearing this in mind, this paper seeks to interpret the “collective images” presented in Daoxuan’s collection of miracle tales, those representations of the miraculous and the supernormal.

The International Commission for the Study and Improvement of Mathematical Education (1950) was interested in updating and developing teaching resources to address the pedagogical problems of mathematics teaching in the mid-1950s. As a result of this concern, the First International Exhibition of Mathematical Teaching Material was held in Spain in 1957, an event that had great international repercussions. This work is situated in the field of the history of mathematics education, so the research method used is historical. The aim is to study those mathematical didactic models which, due to their dynamic and multipurpose nature, stood out at the Exhibition. The results show that these materials contributed favorably to the teaching of mathematics, as they made it possible to work on a wide variety of topics and provided numerous advantages over traditional material. The use of these models meant that the mathematical notions or ideas generally arose from the action that the child carried out with the material; they also made the student the main protagonist of their learning.

Virtual Reality (VR) provides great opportunities for police officers to train decision-making and acting (DMA) in cognitively demanding and stressful situations. This paper presents a summary of findings from a three-year project, including requirements collected from experienced police trainers and industry experts, and quantitative and qualitative results of human factor studies and field trials. Findings include advantages of VR training such as the possibility to safely train high-risk situations in controllable and reproducible training environments, include a variety of avatars that would be difficult to use in real-life training (e.g., vulnerable populations or animals) and handle dangerous equipment (e.g., explosives) but also highlight challenges such as tracking, locomotion and intelligent virtual agents. The importance of strong alignment between training didactics and technical possibilities is highlighted and potential solutions presented. Furthermore training outcomes are transferable to real-world police duties and may apply to other domains that would benefit from simulation-based training. Full article

In mathematics teaching, great efforts are made, and diverse teaching strategies are employed in order to facilitate students’ learning process. Informal environments have proven to be conducive and motivating spaces for science learning. In particular, science museums can be used as a complement and collaborate in order to leverage each of their strengths to motivate mathematics learning. Educational models give a global explanation to the learning process. Taking into account all these aspects and considering van Hiele’s model as didactic reference, we propose the design of a general workshop that has among its objectives the learning of mathematics. To do this, we start from the three main elements and processes set forth in van Hiele’s model: insight, reasoning levels and learning phases. The insight or student’s competence are formulated through Hoffer’s abilities, and for the development of the activities of the learning phases, the STEAM (science, technology, engineering, art and maths) strategy. Once the general proposal has been made, we use it to design a scientific workshop for learning mathematics about cryptography. Our greatest challenge was in generating activities adapted to the established requirements. It would be interesting, for future works, to design research to evaluate the effectiveness of the proposal presented. Moreover, it would be interesting to develop a proposal for assessing student learning. Full article

Early detection of melanoma remains a daily challenge due to the increasing number of cases and the lack of dermatologists. Thus, AI-assisted diagnosis is considered as a possible solution for this issue. Despite the great advances brought by deep learning and especially convolutional neural networks (CNNs), computer-aided diagnosis (CAD) systems are still not used in clinical practice. This may be explained by the dermatologist’s fear of being misled by a false negative and the assimilation of CNNs to a “black box”, making their decision process difficult to understand by a non-expert. Decision theory, especially game theory, is a potential solution as it focuses on identifying the best decision option that maximizes the decision-maker’s expected utility. This study presents a new framework for automated melanoma diagnosis. Pursuing the goal of improving the performance of existing systems, our approach also attempts to bring more transparency in the decision process. The proposed framework includes a multi-class CNN and six binary CNNs assimilated to players. The players’ strategies is to first cluster the pigmented lesions (melanoma, nevus, and benign keratosis), using the introduced method of evaluating the confidence of the predictions, into confidence level (confident, medium, uncertain). Then, a subset of players has the strategy to refine the diagnosis for difficult lesions with medium and uncertain prediction. We used EfficientNetB5 as the backbone of our networks and evaluated our approach on the public ISIC dataset consisting of 8917 lesions: melanoma (1113), nevi (6705) and benign keratosis (1099). The proposed framework achieved an area under the receiver operating curve (AUROC) of 0.93 for melanoma, 0.96 for nevus and 0.97 for benign keratosis. Furthermore, our approach outperformed existing methods in this task, improving the balanced accuracy (BACC) of the best compared method from 77% to 86%. These results suggest that our framework provides an effective and explainable decision-making strategy. This approach could help dermatologists in their clinical practice for patients with atypical and difficult-to-diagnose pigmented lesions. We also believe that our system could serve as a didactic tool for less experienced dermatologists. Full article
