        <p>During the pandemic, education faced challenges coupled with a quick shift to remote learning and mandatory use of online teaching tools, requiring students to manage new technologies and alter their lifestyles. Digital resilience refers to an individual's ability to adapt and cope with digital disruptions, which became crucial in this period. This study examines the post-pandemic condition of digital resilience of the students who attend the Faculty of Technical Sciences in Čačak. A survey was conducted among the undergraduate and graduate students including those who experienced the pandemic during their higher education and secondary school studying. The data on digital resilience elements, such as cyber-security features and communication behaviour, were gathered by the survey. The analysis of the responses provided the deeper insights into the evolution of the students' digital resilience during the global health crisis. It showed up that the students tend to solve the problems on their own and that those who experienced online learning in high school expressed a higher level of resilience. The implications of the study can serve as a guide for further research and practice. Digital resilience, online learning, pandemic</p>

      <title>1. Introduction</title>
      <p>
        The term digital resilience has come into focus recently due to a series of crises which disrupted the
everyday life of millions of people. The earthquakes, military conflicts and the pandemic initiated a
digital shift for many workers and students and their companies and institutions. Working and
teaching/learning online become prevalent. Moreover, such a trend did not stop once the pandemic was
over. The remote work concept proved to be efficient for many companies which kept this model or
moved to a hybrid one. The similar happened to universities. The flexibility and learners' opportunities
emerging from the necessity are likely to shift the expectations of students and educators, eliminating
further the border between classroom-based instruction and virtual learning [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ].
      </p>
      <p>
        There are numerous ways for things to turn wrong and jeopardize business or academic operations
now that the use of digital technologies has become so intensive. There are technical disruptions such
as cyber-attacks, power outages, hardware malfunctions; physical disruptions (eye strain,
videoconference fatigue) and social issues such as inappropriate behaviour (spamming, cyber-bullying,
disclosing private data) or spreading fake news on social media. Digital resilience is the ability to adapt
and cope with such digital disruptions. It is a personal trait that one needs to develop. An individual can
be considered digitally resilient if they possess the capacity to handle the disruption and remain
operative in the digital world. Cyber-security and digital resilience go hand in hand. However, the need
is recognized to shift from traditional cyber security principles (evaluating risks and applying security
measures) to critical digital literacy, digital citizenship practices and socio-emotional learning [

        Arguably the most influential event leading to the wide digitalization of the learning/teaching
process is the COVID-19 pandemic. World Health Organization (WHO) declared the pandemic on
March 11th 2020. Three years later WHO stated that the global emergency was over [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. Universities
and schools all over the world switched to online learning [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. The Faculty of Technical Sciences in
Čačak moved almost entirely to online learning, keeping only freshmen in small face-to-face groups.
During the pandemic, several platforms were activated. The important point was that many students
and professors had already used Moodle and MS Teams for various asynchronous activities. Therefore,
the shift was not too stressful. The teachers who had not previously been familiar with these platforms
started using them and both teachers and students started using video-lectures. After the pandemic was
stated as "not emergent", most teachers and students kept using the platforms for asynchronous learning
and senior undergraduates and graduates were kept in hybrid mode.
      </p>
      <p>This paper investigates how the COVID-19 pandemic and the shift to online learning affected
students' digital resilience. We supposed that there might be a connection between the shift to online
learning (when/how long students were using it) and their digital resilience. Therefore, we conducted
research to gather more insights into digital resilience among our students. Firstly, the related research
is analyzed and the methodology is further presented. Finally, the obtained results are interpreted and
discussed in the conclusion and suggestions for further research are presented.</p>

        Weller et al. proposed a framework for digital resilience in higher education, using the resilience
metaphor from ecology. It proved to be a reliable qualitative tool, useful for detecting areas of concern
and establishing intervention priorities [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ].
      </p>
      <p>
        Measuring digital resilience is a challenge, as this is a complex personal trait. In [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ] authors analyzed
current research in this field. It is concluded that there is an urge to further agree with the digital
resilience conceptualization. Also, it is advised to further engage in longitudinal studies on this topic.
      </p>
      <p>
        Researchers explored how students reacted to COVID-19 in Asia and Australia [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ], regarding their
digital resilience. They used a large sample of students in five countries. The results showed a
significant level of digital resilience and increased digital competencies. However, there are various
recommendations set up in the conclusion, such as the need for providing more interactivity and teacher
training.
      </p>
      <p>
        Sun et al. designed a study to clarify the concept of digital resilience among
students in a school education context, describing antecedents and consequences and
suggesting a conceptual model for health educators [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. This model is circular and it is constructed to
help develop intervention measures for students, acting in an early phase of need for support.
      </p>
      <p>
        Ang et al. developed a digital resilience training program based on theory, evidence, and contextual
information [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. The training was well accepted by the students and both resilience and meta-cognitive
self-regulation scores significantly improved after the training program.

      <title>3. Research Methodology</title>
      <p>This research aims to determine potential differences among the students in the improvement of
digital skills (based on their self-assessment) depending on the duration of online classes at faculty or
secondary school. Also, one of the objectives is to explore in how students used technology for online
teaching and learning during the pandemic.</p>
      <p>Quantitative analysis was conducted to collect data. For this purpose, a questionnaire was developed.
The first part of the questionnaire includes the questions about the study year, study programs, and the
duration of the online classes. The second part of the questionnaire contains the questions about used
platforms, antivirus programs, passwords, the causes of the problems with platforms, how students
solved the situations, such as losing the data for studying, etc. The third part of the questionnaire is
related to behavior in case of unpleasant situations in communication with others, help-seeking, and
improvement of the digital skills. The study was conducted at the end of the summer semester (July
2023).

      <title>Research questions</title>
      <p>Based on the main research aim, the following research questions can be identified:
• Are there any differences among the students who attended online classes over a shorter or
longer period in the estimation of the improvement of digital skills?
• Which platforms did the students mainly use during the online classes?
• How did they use technology and how did they solve technical and other problems during
online teaching and learning?

      <title>Sample</title>
      <p>A sample consisted of 64 Faculty of Technical Sciences in Čačak students (University of
Kragujevac). Most of them were in the first year of study (28%), 25% of them attended the second year,
while the percentage of the students attending the third year was 12%. There were 15% of students
attending the fourth year and only 3% of the students were in the fifth year of studies. The total number
of Information Technology students was 77.6% while the rest of them were the students of other study
programs in the technical field.</p>
      <p>To determine whether the students attended online classes, they were asked to declare how long (in
the number of semesters or school years) they were in an online teaching mode. Due to the differences
in the duration of the studies, some students had the online classes either only in the secondary school
or only at Faculty, or both. (Table 1 and Table 2).</p>
      <p>The results of the research are presented according to three research questions. To determine whether
there are differences in the estimation of improvement in digital skills between students who attended
online classes over a shorter or longer period, ANOVA analyses were conducted. The results of
descriptive statistics are presented in Table 3 and Table 4.</p>

        <p>There are no statistical differences among the groups of students who did not attend online classes
at the Faculty and the other groups of students (more than 4 semesters, 2-4 semesters, one semester), F
(3,60) = 0.663, p = 0.578. However, there are significant differences in the estimation of improvement
of digital skills among the students who attended online classes for more than one school year and the
students who did not attend classes in online teaching mode during secondary education (F (3,60) =
3.981, p = 0.012). A longer period of online teaching during secondary school education resulted in
higher estimations of improvement in digital skills (M = 4). Such findings have been expected regarding
the fact that the students at the Faculty have more experience with technology, especially due to their
fields of study.</p>
        <p>However, because of the small number of students in different groups, these results cannot be
generalized. They can be used as an initial insight into students’ evaluation of improvement in digital
skills after a period of online learning and teaching.</p>
        <p>The students were asked to select which platforms they used during online teaching mode. The
results are shown in the following table (Table 5).</p>
        <p>As shown in Table 5, more than half of the students used Microsoft Teams for asynchronous and
synchronous communication. It means that the teachers used the platform for sharing files, and
communicating via chat, as well as for real-time classes. LMS Moodle was also frequently used. Based
on the frequency, it can be concluded that online teaching was organized in different ways and
supported by various platforms.</p>
        <p>On the five-point scale, students assessed how often they had technical obstacles during online
classes (Table 6).
N = 64</p>
        <p>According to the result, the main problem was weak internet connection. However, we can conclude
that there are three problems whose estimates are below 3. This indicates that students did not have
technical obstacles during online teaching and learning which was expected regarding to students’ field
of study.</p>
        <p>The students were also asked (on a five-point scale) to estimate in which way they would solve
potential problems (Table 7).</p>
        <p>The students prefer to solve problems on their own by searching for solutions on the internet rather
than seeking help from the others (M=3.89). It would be interesting to explore possible reasons why the
students prefer to search for solutions independently. It can be either because of their developed digital
skills or a poorly developed skill for communicating and seeking help.</p>
        <p>As many as 34.4% of students declared that they lost data (documents) for study or school in some way.
The causes were different (Table 8).</p>
        <p>The results indicate that around one third of students lost their documents for study, and most of
them (about 14%) are not sure about the reason for losing the data. About 11% declared that the file
was deleted by mistake.</p>
        <p>In case they lost the documents for studying (project, document, etc.), the students were asked to
choose how they solved the situation (Table 9).</p>
        <p>According to the results, the students mainly prefer to try to finish their tasks again. Therefore, we
can conclude that the students do not give up the task in case they lose the documents.</p>

        <p>Most students back up their data in some way (75%). They did not have problems with computer
viruses or similar malicious programs during online teaching (only 9.5%). Only 4.7% of students state
that the virus caused problems during online classes or finishing tasks.</p>
        <p>To determine how the students protect their devices from the viruses, they were asked whether they
have installed an antivirus software. The students mainly use the embedded antivirus software by
Windows OS (56.3%). About 40% of students use other programs such as Kaspersky, Avast, etc. Only
3.1% of students are not sure about the installed software.</p>
        <p>Additionally, it was also interesting to explore how the students generally use passwords (Table 10).</p>

        <title>Using passwords</title>
      </sec>
      <sec id="sec-6-9">

      </sec>
      <sec id="sec-6-10">

      </sec>
      <sec id="sec-6-11">

        <p>for less important I use simple passwords.</p>
      </sec>
      <sec id="sec-6-12">
        <title>I use the same, strong password for most systems.</title>
      </sec>
      <sec id="sec-6-13">
        <title>I use the same, simple password for most systems. N = 64 Frequency 9</title>
        <p>It seems that the students are aware of the importance of properly used passwords. As many as 42.2%
of them use strong passwords for important systems while they use simple passwords for less important
ones. Only 4.7% of students use simple passwords for most systems.</p>
        <p>On the other hand, one of the research questions is related to seeking help from others and behaviour
in general in unpleasant situations on the internet (spamming, insulting, sharing personal data, etc.).
The results are presented in the following table (Table 11).</p>

        <p>Related to other patterns of behaviour in case of problems on the internet, students were asked which
strategies they would apply to solve the situation (on a five-point scale) (Table 12).</p>
        <p>The highest estimated statements are related to blocking the contact and ignoring the situation which

      <title>5. Conclusions and future work</title>
      <p>This research confirmed several authors' assumptions regarding the use of technology in the previous
period, particularly in the pandemic period. A great majority of students used online learning either in
secondary school or at the faculty and became familiar with a wide scale of digital tools and platforms.
The results have shown that the students' digital resilience reached a significant level. The students who
spend more time learning online in secondary school tend to perceive higher digital skills and therefore,
can be more digitally resilient.</p>
      <p>This research also showed that the students mostly decide to rely on their own when it comes to
various disruptions of their digital operations. As one pillar of digital resilience is actually seeking help,
this finding is drawing our attention. It is important to build institutional help and provide procedures
and guidelines for students facing various digital challenges. Also, peer help and building a community
of trust, comprising both students and faculty staff, should be promoted.</p>
      <p>Digital resilience is a complex trait and cannot be easily measured. It heavily relies on the subjects'
properties. Therefore, it is important to improve the data collection tools and eventually adapt the
questions trying to acquire a better image of participants' behaviour and digital practice. For example,
75% of students said they regularly performed a backup which represents quite an indicative and
significant number. It is questionable if all participants are actually familiar with details of what is
considered a real backup and if all the systems being used are actually taking care of keeping the backup
automatically.</p>
      <p>For future work, it is advisable to improve the questionnaire and further tackle the issue of help, or
in other words investigate what kind of assistance would be preferable for students. Also, carefully
constructing the aggregate variable representing digital resilience could probably expose additional
insights into digital resilience structure.</p>
