2. Literature Review
“Distance education” is meant to include synchronous and asynchronous educational environments which presuppose the extended use of technological means, such as efficient internet services and personal devices, along with experienced teachers and specially designed teaching and learning sequences, in order for the lack of physical communication to be moderated. “Online learning” offers real time communication and interaction, although students and teachers are connected from different places, usually their homes. A digital platform is usually the educational environment, in which teachers develop their teaching activities and call students for participation. Appropriate teaching practices, along with adequate infrastructure, enhances students’ participation and makes online education effective [
4].
The literature on distance education is very rich. Students’ engagement in the learning process and interaction between each other is a component highly demonstrated by many researchers [
5,
6,
7,
8]. Students’ active involvement, relationships between students, relationships between students and teachers, and students’ motivation are often underlined as important components of effective distance learning environments [
4,
8,
9].
In the last two years, there is an increased interest in science education researchconcerning the implementation conditions of distance learning due to the COVID-19 pandemic. Some research revealed problems with internet access and lack of infrastructure [
1,
10,
11,
12,
13], others revealed the importance of the conditions existing in home environment [
14,
15,
16], others recorded the difficulties faced by students in terms of communication, self-discipline, and motivation [
17,
18,
19], and others examined students’ readiness to learn online and also teachers’ readiness to teach online [
20,
21,
22]. Moreover, an increase of inequalities in learning opportunities during the COVID-19 pandemic was recorded by several researchers [
2,
23,
24,
25].
OECD examined the responses of 98 countries to the disruption of school-based education for several months. In the report, several aspects of online education were investigated, such as schools’ and teachers’ preparedness, the adequacy and availability of technology, students’ access to the digital world, and students’ access to a quiet place in their homes [
22]. The report indicated that several countries like Greece suffer from lack of most prerequisites that could support science distance education. For example, in Greece, the percentage of students in schools whose principal agreed that the school has sufficient qualified technical assistant staff is the second lowest among 98 countries. Moreover, on average across OECD countries, there is almost one computer available at school for every 15-year-old student for educational purposes. In Greece, the corresponding ratio is just 0.25, which means that there is only one computer for every four students.
A similar report coming from the European Union sounds alarm on both the short- and long-term consequences of COVID-19 in education. According to the report, the educational loss by the change from school-based to remote schooling education is taken for granted. Educational institutions all over the world have acknowledged problems such as lack of student–student and student–teacher communication, increased stress, and lack of motivation [

In Greece, Anastasiades [
26] described in detail the implementation of distance education during the COVID-19 pandemic emphasizing the pedagogical dimension and the opportunity “of transition to the open school of inquiry-based learning”. Karadimou and Tsioumis [
27] described the general impact of the COVID-19 pandemic on the Greek educational community and focused on official instructions derived from the Ministry of Education. Geropoulos et al. [
28] have taken 43 secondary head teachers’ interviews and showed “the inadequate level of readiness of the state mechanism to cope with the educational requirements arising from the crisis” (p. 60).
However, research on the distance teaching of specific teaching subjects during the COVID-19 pandemic is relatively limited. A few studies concerning primary and secondary education in various countries have tried to reveal the features of science teaching during the COVID-19 pandemic.
In the USA, Macias et al. [
29] conducted a study on the impact of the COVID-19 pandemic on science teaching and science teachers of the eighth grade. The answers of 515 teachers ascertained much less student engagement in remote learning, less time spent on science lessons, and little implementation of the instructional methods aligned with NGSS like investigations, group work, or analyzing data. In contrast, watching videos and using online simulations and reading material emerge as the most used practices (p. 4).
In Canada, McPherson and Pearce [
30] investigated tensions and contradictions of practices that science teachers faced during the COVID-19 pandemic through professional development of ten secondary science teachers. Teachers reported “frustrations with student engagement during online lessons” (p. 8) attributing this behavior to less opportunities to interact with experiments, demonstrations, or modeling. Moreover, teachers struggled with students’ fair evaluation and with the need to shift their own professional practices.
In Indonesia, Wisanti et al. [
12] recorded 177 secondary science teachers’ difficulties and challenges regarding science teaching during the COVID-19 pandemic. Findings concerned three main factors: technology, students, and teachers. Concerning technology, most teachers (77.5%) had difficulties with management of online learning especially with internet access. Students showed low motivation, lack of discipline, and lack of communication equipment. The greatest challenge that teachers faced was concept explanation without practical work implementation. Half of the teachers tried to change practical work with another task, 20% skipped it completely, and only 3% used a virtual laboratory to replace practical work. Moreover, a significant 36% declared a lack of application operating skills (p. 8).
In UAE, Al Darayseh [
31] investigated the impact of the COVID-19 pandemic on the modes of teaching of 62 secondary science teachers. According to 46% of the surveyed teachers, the main challenge of the online learning environment used during the pandemic was the lack of hands-on activities and experiments. Another problem was limited interaction in the online classroom accompanied by teachers’ difficulties with fostering interaction between students and teachers. The management of students’ behavior and the management of technical issues were recorded to a lesser extent. These findings probably explain teachers’ preference to teach science via a traditional classroom (46%), while 32% would prefer blended teaching, and 22% virtual teaching (p. 114).
In Turkey, Avsar Erumit et al. [
32] explored 37 science teachers of fifth through eighth grade and their adaptations to online teaching. Teachers found it very difficult to motivate their students; this is the reason they looked for fun ways to keep students engaged as well as interactive tools “such as web 2.0 tools, virtual labs, interactive games, and videos” (p. 44). In another study, six elementary teachers’ transition to remote teaching was explored with emphasis on inquiry-based teaching practices [
33]. Teachers admitted that the nature of the activities in remote teaching “did not match inquiry-based instruction” (p. 74), even if they used models or online videos. In contrast, when parents were asked to judge remote teaching, they found that “videos used during science instruction were arresting” [
34] (p. 1902), but they complained about insufficient corrective feedback, short lesson duration, the absence of experiments, and the lack of students’ active participation and social interaction between students (p. 1906).
In the UK, Leonardi et al. [
35] have taken in mind the impact of the COVID-19 pandemic on primary science education in the annual report of the Wellcome Trust CFE Research 2021. Via this project, data on the way science is taught across the UK, including time spent and attitudes towards science, are annually reported. In 2021, a sample of 2823 primary teachers focused on the use of Explorify, a free digital resource for science teaching. The majority of teachers agree that science teaching was affected by the pandemic, meaning that less science was taught remotely, the curriculum was not fully covered, they couldn’t work scientifically, and more adaptations than in other subjects were needed to teach science at a distance [
35] (p. 3). In particular, teachers declared that they have taught less science (56%) and have used fewer investigations (80%) (p. 22). Gaps in students’ knowledge and investigation skills were reported by 67% of teachers (p. 38). Teachers found it difficult to differentiate science lessons (82%) and felt unable to assess students’ progress (62%) (p. 23). Moreover, fundamental science activities, such as observation, recording, and analyzing data decreased in remote teaching (p. 40), while sharing videos in online class and at home increased (p. 46). In conclusion, 72% of teachers find it difficult to teach science remotely and 54% agree that is easier to teach other subjects remotely (p. 23).
In Greece, Stefanidou et al. [
36] investigated secondary students’ views on distance physics teaching during the COVID-19 pandemic revealing positive and negative aspects of online education. In a similar way, Mandrikas et al. [
37] investigated primary students’ views on distance science teaching during the COVID-19 pandemic demonstrating several problems and poor knowledge results. Both studies highlight students’ views on distance teaching and learning, which is very important as students are the receivers of any change made in education during the COVID-19 pandemic. Moreover, they refer to science, a particular subject with laboratory requirements for in-class teaching.
Nevertheless, research on the differences between science distance teaching in primary and secondary education in the same country is missing. In the present study, the views of students in Y6 and Y10 on science distance teaching in Greece are compared, so as to reach conclusions concerning science distance teaching during the COVID-19 pandemic throughout the system of compulsory education in Greece. We consider this overview interesting, because it could provide the possibility of locating deeper insights about science teaching regardless of the pandemic. Genuine interest, provision of experimental equipment, teaching methods, science practices, time spent, amount of knowledge provided, type of skills cultivated, and students’ response to science teaching are some of the issues that determine the reception of science in school at any educational level. Therefore, emerging similarities, differences, discontinuities, difficulties, requirements, and recommendations could be useful to science teachers, stakeholders, and science curriculum designers. Moreover, according to the findings, some practical implications depending on the age of the students could be suggested for more effective science teaching in any teaching circumstances. Finally, the results could be compared with those of other countries and contribute to a further discussion on science education.
3. Methodology
3.1. Research Question
The research question of this study is as follows: What are primary and secondary Greek students’ views about the distance teaching of science during the COVID-19 pandemic regarding (a) students’ interest in science, (b) students’ communication with teachers and classmates, (c) changes in teaching practices, (d) concentration and understanding of science concepts, and(e) students’ overall evaluation of science teaching at a distance.
3.2. Sample
The sample of the present study consists of 378 primary students (students in Y6, 12 years old, 165 male and 213 female) and 197 secondary students (students in Y10, 16 years old, 80 male and 117 female), who voluntarily participated in the research. These students attended public schools in Attica (Greece), 24 elementary and 20 secondary schools, which derived from all district areas of Athens and Piraeus representing every social and economic background.
As part of the national strategy for the confrontation of the pandemic, all students in Greece attended distance teaching during almost the last two school years. Specifically, during the previous year (2019–2020) schools were normally open from September to March, when the World Health Organization (WHO) declared COVID-19 a pandemic. Therefore, students continued science education remotely until June and in-person again for just 15 days before the end of the school year in June 2020. Regarding the next school year (2020–2021), schools opened for just one month at the beginning of the school period and went to distance education for the rest of the school year.
3.3. Data Collection
Two similar questionnaires, appropriate for each educational stage, were created and used for data collection. The questionnaires consisted of twenty-three (23) Likert scale, either 1–5 or 1–3, closed-ended questions and two (2) open-ended questions to shed light to the qualitative characteristics, and particularly to map students’ views on what they liked most and least in science teaching by distance. The questions were organized in five categories, according to the previously mentioned aspects which the research question is analyzing. These categories were formed based on corresponding classifications in similar studies [
1,
5,
8,
20,
22].
The validity of the research tools was supported due to the correspondence of the questions’ content to students’ views on distance education (content validity) and vice versa, the questionnaires included all aspects of science teaching at a distance, as they were organized in the five groups mentioned above. Moreover, the questionnaires were thoroughly tested by two expert, experienced teachers at each stage of education, to adjust the language in primary and secondary students’ levels. Clear instructions and explanations were given to students in order to complete the questionnaire.
The questionnaires were transformed in digital form and distributed electronically, attached to a cover letter for parents and students. Finally, they were answered anonymously outside of school hours.
3.4. Data Analysis
Closed-ended questions were categorized according to the pre-defined response grades and are presented in tables.
For the analysis of open-ended questions, an inductive approach for qualitative data analysis was used [
38]. Students’ answers were indexed and categorized according to their content by the first author who grouped similar answers creating codes. The second author repeated the inductive process. The level of agreement between the two authors (coders) was depicted to Cohen’s kappa 0.8. A third coder helped with the points of disagreement. Descriptive statistics were used to quantify the findings and provide a clearer picture of the similarities and differences between primary and secondary students’ views on distance science education. An independent t-test was used to determine whether there was a statistically significant difference between the results of the two groups. An alpha level of 0.05 for all statistical tests was used.
Quality criteria for supporting trustworthiness were implemented. Credibility was established by peer debriefing. Particularly, an expert in the field thoroughly explored the methodology followed, and the data acquisition and analysis, as well as the formation of the findings. He served as a critical reviewer, asking questions and making recommendations. Transferability is enhanced by the fact that the authors describe in detail the research, from its context to its results, informing interested researchers about the possible repeatability to further situations. What follows is a comparative presentation of the findings of the two different groups (primary and secondary students).
5. Conclusions
This study aimed at mapping the similarities and differences between the views of students in Y6 and students in Y10 on science distance education during its implementation due to the COVID-19 pandemic in the school year 2020–2021 in Greece. The findings revealed that both primary and secondary students had mainly negative views on science distance teaching. Their views seemed to be negatively influenced by the technical issues such as poor network connection, the limited student–student and student–teacher interactions, and by the limited or complete lack of laboratory activities. However, a limited number of students pointed out some positive experiences from the prolonged period of distance education. Such positive aspects are the increased and effective spread of audiovisual material, such as selected software, animations, and videos. This kind of material helped in the conceptualization of the content under consideration and are recommended to be adopted in science teaching more broadly, and not only in the context of distance education. Regarding the comparison between the stages, it seems that more technical problems were reported by primary education students, while secondary education students reported more profound worries and difficulties related to teaching practices.
Students’ answers can be used for the appropriate planning of successful science distance education at both stages. For example, the use of audiovisual material and applications (simulations, ppt, video experiments, etc.) can improve students’ understanding of concepts. In contrast, elements that should be avoided are technical problems, limited communication, and lack of experiments. These results are consistent with relevant research on distance education both during closure due to the COVID-19 pandemic [
13] and earlier [
41].
Limitations arise from a limited and convenient sample and do not allow trustworthy generalizations. Τhe greatest risk of bias is that students who had good access to an internet connection and equipment may have responded to our survey and students with less facilities may not to have responded.
Findings call for further research, including science teachers’ perspectives on distance education, and particularly, the pedagogical, didactical, and institutional aspects that distance education affects. Moreover, different socio-cultural backgrounds need to be investigated. This is in line with the OECD report for Greece, which reveals poor availability of technology and technical assistant staff in schools [
26]. Students’ opinions could be checked by mapping teachers’ corresponding opinions [
42,
43,
44,
45,
46] as teachers were the persons who undertook and implemented the unprepared transition to distance education during the COVID-19 pandemic. Finally, the present study asks for further research so as to raise the quality of science teaching material for online settings, along with teachers’ training in both digital technologies and distance education, in order for distance teaching to become more effective not only in fighting of the pandemic but in other circumstances as well.
