In summary, this introduction, drawn from insights by various authors, underscores the transformative journey of education into the digital realm, shaped by unforeseen global events and ongoing scholarly discourse.
It is essential to underscore the significance of analysing the specific context of Slovakia and Hungary in our study. The limited existing evidence necessitates a closer examination of the unique circumstances in these regions, making these two countries the exclusive focus of our research.
This study aims to address this gap by providing a detailed analysis of the IT usage habits of university students in Mosonmagyaróvár, Komárom, and Košice. Our objectives include elucidating the impact of online education on these students, understanding the sustainability implications, and contributing valuable insights to the existing body of knowledge.
Literature Review
Online education exists in many forms, and its widespread use (and occasionally even its upgrading or expansion) was forced by COVID-19.
According to studies by Dag and Gecer [
8], the most popular digital learning forms in many countries in the world include e-learning, Internet learning, distribution learning, network learning, telelearning, virtual learning and PC-controlled learning. Although online education can take place in many ways—frontal, feedback, face-to-face, or as an opportunity for self-research or self-learning—in the view of some researchers, it seems less effective than classroom or onsite education.
Based on the surveys by Zapata-Cuervo et al. [
9] in the United States, South Korea, and Columbia, online education was, overall, less effective. However, students’ self-efficiency and anxiety have significantly influenced their commitment to online, influencing their online learning results.
Online education has different modalities, including synchronous and asynchronous learning. Synchronous learning involves real-time interaction between instructors and students, fostering immediate engagement. This mode, often facilitated through live lectures, webinars, or virtual classrooms, enhances students’ sense of connection and community. On the other hand, asynchronous learning unfolds without real-time interaction, providing flexibility for students to access learning materials and complete tasks at their own pace. Discussion forums, pre-recorded lectures, and self-paced modules characterize asynchronous learning. These modalities have been explored by various researchers, including Lee et al. [
10], Razami and Ibrahim [
2], and Tam [
11], who have discussed ways to enhance the efficiency of online learning with a focus on interaction, application, and self-managed learning [
2,
10,
11]. Lee et al. [
10] examined how to make online learning more efficient with questionnaires. They discussed three main topics: interaction, application and self-managed learning. Razami and Ibrahim [
2] highlighted interaction, motivation and concentration in a similar survey. Tam [
11] claims that taking exams from home improved students’ constructive attitudes. They learned more actively, reviewed their notes more frequently, and asked for information and feedback.
Also, the attitude of teachers plays a vital role in the effectiveness of online education. Studies by Kross et al. [
12] were conducted among 2260 people in the United States, and Hung et al. [
13] also measured the online learning ability in Taiwan with a confirmation factor analysis. Five dimensions were considered in the surveys: self-directed learning, learning motivation, computer/Internet self-efficiency, student control, and online communication self-efficiency. The results have shown that teachers play a significant role in developing two dimensions: self-directed learning and learning control skills. They can help students develop their time and information management. In addition, students with less self-confidence should be encouraged in online communication. Hoang and Hoang [
14] had the same opinion in their surveys in Vietnam. Han and Geng [
15] also highlighted the same issue in their examination in China. In addition, they noted that, for more efficient learning, teachers should clarify the goals and the course guidelines before the lecture, offer high-quality online materials and immediately respond to students’ questions through messaging interfaces. Five dimensions of self-efficiency have been identified by Shen et al. [
16] (the same in serial numbering as above): (1) self-efficiency in completing the online course, (2) self-efficiency with classmates, (3) self-efficiency in device management. (4) self-efficiency of interactions with instructors, (5) self-efficiency of communication with students for study purposes.
The efficiency of online learning is significantly influenced by students’ using habits of IT devices, the degree of their orientation in online space, and their preparedness. The survey by Akuratiya and Meddage [
17], conducted among 130 first- and second-year medical students, is also worth mentioning. According to its findings, switching to online education was much more complicated in Sri Lanka because 62% of higher education students had little or no experience with IT devices. About 54.7% of students preferred printed literature to digital. Smartphones were used mainly during the lectures (43.8%); 37.5% of the students preferred the laptop, while 1.6% used tablets in this activity. A total of 17.1% of students used their laptops and smartphones in the same proportion during their online work. However, after lifting the restrictions, 82.9% of respondents said they could imagine continuing this type of distance education.
Hermanto and Srimulyani [
18] received similar results for preferred IT devices in online education. A total of 108 lecturers and 386 students participated in their Indonesian survey. A total of 34.8% of the students preferred the smartphone, while 26.68% preferred the computer, laptop, or a combination of the two. The Internet was mainly used for receiving information during online education, but many people also preferred TV and smart boards.
A survey conducted by Deés [
4] at the Edutus University in Hungary established that students who had previously worked less on online interfaces or preferred IT devices in their studies to a lesser extent were uncertain about this new type of assignment. In this case, this was a problem because they enjoyed the greater independence to complete their studies more responsibly. The author points to the fact that, in 2018, it was noticeable that students neglected learning from books. The students opted to browse the Internet to expand their knowledge. She also stated that students who attended an Engineering Programme were more satisfied with the quality of online education than students with a major in Economics.
Sarfraz et al. [
3] found that medical students’ higher results in online learning were related to their preparedness for online learning on behalf of students and lecturers. Kang’s studies at the University of Medicine also showed that higher-grade students used their online space more routinely, spending more time on learning and research than lower-grade students.
Furthermore, the motivation and satisfaction of students play a crucial role in the success of online education. Studies by Brahmasrene and Lee [
19], Martin et al. [
20], and Dymek et al. [
21] highlighted the impact of students’ preparedness, satisfaction, and intention to use online learning in the future. Students’ satisfaction can lead to the successful application of online education in the future, as suggested by research findings by Chamdani et al. [
22] in Indonesia. Several surveys were conducted after the pandemic. The research findings by Chamdani et al. [
22] in Indonesia show that 50% of students were satisfied with online education, and learning motivation did not influence their views on online lectures.
Online education during the COVID-19 pandemic, various techniques and programmes were used by universities to provide lectures. Students were optimistic about the following online techniques, devices and methods: semi-directional communication, SPADA, Google Meet, WhatsApp interface, study videos, video conferences, theme of lectures, lecture style, and method of presentation. Susila et al. [
23] found that Indonesian students preferred visual presentations to auditive methods. The authors’ survey revealed that, in the case of lectures, the visual method seemed more preferred than the auditive method. Overall, students had very different opinions about online education. Surveys conducted in several countries have confirmed that students are satisfied with this method of education; therefore, they will participate in online education in the future.
The advantages and disadvantages of online education were studied in many ways by researchers. In Deés’ [
4] survey, 50% of students’ opinions suggest that they were comfortable attending lectures from home to save travel costs and make their time more flexible. The lecturers were maximally helpful, preparing their lessons creatively. In addition, a decrease in stress due to the exam was observed. As a disadvantage, students mentioned the lack of personal contact, some lecturers’ insufficient grounding in online education, technical problems, and the adverse effects of all-day sedentary work on health.
Online education significantly contributes to sustainability by minimizing the need for travel to educational institutions, thereby reducing greenhouse gas emissions. Additionally, it saves valuable time and alleviates the traffic congestion, fuel wastage, and noise pollution associated with traditional commuting. Particularly significant savings can be made if students only leave home to take an exam. These examinations can be quickly and easily carried out from home.
Song et al. [
24] examined the participants in two groups: those who were satisfied with online education and those who were not. In both groups, it was stated that students liked the evolution of the course. Both groups were satisfied with the comfort of the technology. However, it was more problematic to manage time and keep students motivated. The students’ opinions were similar in a similar study by Kazainé Ónódi [
25]. She presented her results on a five-grade Likert scale, with a value of 4.5 for satisfaction of seminars. The students positively experienced that the online lessons were convenient, and that new students were in contact with each other and friendships were formed. Peimani and Kamalipour [
26] found that eye contact was important for students during online seminars. However, they considered it more important to see their teachers and their companions than to be visible themselves. It was also found that participants preferred online seminars to pre-recorded seminars. Han et al. [
27] grouped 317 participants according to their preference for content-oriented or practice-oriented learning. The survey revealed that the practice-oriented strategy was less effective in terms of results and, overall, the students were less satisfied with online education. In a study by Riaz et al. [
28] in Saudi Arabia, students were very positive about their home learning. People returning to universities after the closures complained about fatigue (77% of survey participants), demotivation, and unhappiness (63%). Most of the students thought they could study more conveniently in online lessons, were more alert, and had higher exam scores. Also, Nikou [
29] stated in a survey that students had a favourable opinion of online education opportunities. A total of 159 students, when asked by Giovannella [
30] (95% women), also made the same statement—however, the interaction between lecturers and groupmates needed to remain continuous. Almuraqab [
31] included 133 students in his survey in Dubai. The gender distribution of this study comprised 53% female and 47% male participants aged between 18 and 24 years. A total of 62% of the respondents were satisfied with the opportunities offered by online education. A total of 73% of them thought they could do their job much more efficiently because of the flexibility of working from home. The students mentioned that they could save time by not having to devote time to travel. Looking at the negative and positive aspects, 55% of students liked distance education, while 45% did not. Overall, however, only 25% of them would completely stop online education, while others would continue to use the opportunities offered by online education, either in full or in a hybrid method. Frederick et al. [
32] obtained the same result. It is clear from their studies that during both online and hybrid education, young people considered flexibility, autonomy and the diversity of curriculum as positives. However, most of the respondents preferred hybrid education. Almahasees et al. [
33] reported the same opinions from their surveys in Jordan, and so did Hegde et al. [
34]. Bali and Liu [
35] also achieved similar results, as students preferred traditional lectures, but they quickly discovered the potential and positive side of online education (autonomy, time-saving, cost-effectiveness). Van et al. [
36] found that online education was positively judged by students. Therefore, they suggest that teacher training colleges should specialize in preparing trainers online, allowing for the opportunity to continue online lectures. A survey by Saeed and Almende [
37] in Saudi Arabia concluded that, among the 2030 students surveyed, female respondents had a higher preference for online education than their male counterparts. In addition, lower-year pharmaceutical students found personal lectures more favourable. They seem to be less prepared for online education and have less autonomy in learning. Among the disadvantages of online learning, students mentioned technical problems, an uncomfortable environment at home, and demotivation.
Surveys by Huang et al. [
38] in southern China also show the reduced motivation of students, although there were significant differences in students’ online learning skills. Gross and Uppsäll [
39] obtained similar results in Sweden in the case of IT students. Students were less motivated; it was harder for them to concentrate and maintain their self-discipline.
In addition, in higher-education institutions, students could take exams from home. This option was generally experienced by the students as positive. Luo and Hiang [
6] also emphasised that it was important for lecturers to create a motivating online learning environment and service systems for home learning and change students’ views on online education. Su et al. [
40] believe that this should be formed according to students’ needs, which are influenced by their social origin.
Saving energy is a significant concern: universities use lighting, heating, computers, and air conditioning most of the day. Students can control their energy use at home, significantly reducing unnecessary energy use.
In some regions, online education was clearly rejected by students. Hilaria et al. [
41] found in their examinations that 62% of students negatively assessed the shift to online education. Students said the interaction was limited or exhibited misunderstandings about the written texts. Nevertheless, they did not experience demotivation or a decline in academic results. Jamil and Tasir [
42] also highlighted the importance of lecturers in terms of students’ interactions with each other. A survey by Dindar [
43] in Turkey supported the same view by pointing out that students are more likely to attend face-to-face seminars than online lectures.
Thus, in the countries mentioned above, online education was carried out relatively smoothly during the pandemic. It should be noted, however, that closures were also imposed in developing countries. In these states, there were many more challenges for both students and lecturers in switching to digital education. [
44]
Surahman and Sujarwanto [
45] found that students preferred hybrid learning at the University of Siliwang in Indonesia, because of the slow Internet connection. Wang et al. [
46] highlighted the need to develop online education platforms. In Malaysia, online education is also in its infancy, which causes a high level of dropout in higher education. Students were asked about enforced home learning because of the COVID-19 pandemic. They evaluated this form of education positively. Therefore, Tan et al. [
7] consider improving the quality of this domain. Harefa és Sihombin [
47] also mentioned, in their studies, that students living in the countryside faced more difficulties in participating in online education for technical reasons. The lecturers also needed to adapt to this situation.
In a survey, Susila et al. [
23] found that although 100% of students had a mobile phone, and 86.8% had access to the Internet, only 52.6% had continuous Internet service, and others were stuck. For this reason, 84.2% of the students do not want online education in the future.
The health effects of online education could primarily be examined during the pandemic. In the Hungarian survey by Szemes et al. [
48], the impact of epidemiological measures was examined among students aged between 18 and 25 years during the first period of the pandemic. A total of 54% of them mentioned a reduction in personal relationships in terms of learning, and mentioned working at home as a discommodity. However, 65% believed that their leisure activities did not change during the pandemic. In terms of health, it is a disadvantage that smoking increased by 1.6% during this period, and alcohol consumption by 11.8%. Nevertheless, it can be stated that there was no change in health and risk behaviour. It should be noted that both women and men found a way to complete some sports activities. Women accessed live-streaming workouts and exercises on videos posted on sharing sites. Adverse effects, such as weight gain or increased alcohol consumption, were more common in the case of men. In addition to physical activity, people’s psychological status changed a lot during the period of online education and curfew. Rozali et al. [
49], in their survey of 127 technical students in Malaysia, investigated the impact of the pandemic on health, looking at gender differences. A study with a quantitative research plan showed that there was no significant difference in psychological well-being related to gender.
E-learning contributes to reducing the food waste and expenses associated with impulse purchases, as students often buy food on campus or on-the-go that goes uneaten. Additionally, home-based learning helps minimize the consumption of single-use PET bottled beverages, promoting cost savings, and address ongoing concerns about PET bottle recycling.
Hayat et al. [
50] and Howcroft and Mercer [
5] found similar problems with students’ mental health at the University of Waterloo Ethics Office. Studies by Puiu et al. [
51] in Romania show that the stress experienced by the students stems from additional factors, as well as the lack of social relationships. Students experienced more stress when communication problems occurred during online education. Lecturers played a significant role in reducing stress levels. The following tools were used: brainstorming, games, and quizzes. In addition to communication problems, technical problems also increased students’ stress levels. Studies conducted by Lim et al. [
52] and Khumya et al. [
53] in the Philippines drew attention to the importance of higher-education institutions preserving the mental health of students and meeting their social needs. As a result of the sudden transition to online education, a large number of students experienced depression, anxiety, stress, and fatigue.
Based on the previous literature review, the authors of this study considered it essential to survey two Central European countries, namely Slovakia and Hungary.
The following research questions were defined:
How do students’ preferences for the devices used in studying and leisure activities in Hungary and Slovakia compare to studies in other (non-European) countries, and what role does their overall experience with IT devices play?
What are the commonalities and differences in students’ perceptions of online learning, including advantages, disadvantages, and changes in habits during the pandemic, and how do these align with the existing literature?
How do correlations between IT device usage, time spent on activities, and perceptions of digital learning materials differ between institutions, and what key factors contribute to the variation in experiences?
