Purpose: The purpose of this study was to determine the impact of perceived usability and students' personality traits on their learning gain in an e-learning context at the university level. Design/methodology/approach: The factors examined are related to individual characteristics such as students' personality traits, as well as to perceptual characteristics such as the perceived usability of the platform used. A total of 110 undergraduate students participated in the study. A one-group pretest-posttest research design was adopted. Big 5 personality test, System Usability Scale (SUS) and a general knowledge assessment questionnaire were used. Findings: Perceived usability of Zoom platform is statistically significantly correlated with students' learning gain (r = 0.294, p = 0.002, s). Concerning learning effectiveness in the current e-learning scenario, students' final performance was found to be statistically significantly higher than the initial (p = 0.000, s). A hierarchical regression analysis (R[superscript 2] = 0.146) unveiled that Zoom's perceived usability and personality traits are significant predictors for learning gain (p = 0.011, s). Research limitations/implications: The findings of this research provide important implications regarding the design of lessons in an e-learning context. Social implications: A substantial fraction of the educational process is going online, especially in higher education. Thus, a thorough understanding of the factors which influence learning gain in an e-learning context is of significance. Originality/value: The main contribution of this study is that it quantifies the variance of the learning gain explained by two factors, namely, SUS and personality.

Purpose: The purpose of this paper is to investigate the impact of personality traits on the perceived usability evaluation of e-learning platforms. In specific, perceived usability levels of the educational platforms and tools used in primary and secondary education in Greece are demonstrated. The impact which personality traits and other individual-related factors have on the perceived usability were also examined. Design/methodology/approach: In total, 2,239 Greek primary and secondary education teachers participated in the study through an online survey. The system usability scale (SUS) and Big 5 personality test questionnaires were adopted, as well as a demographics questionnaire and nine platforms were examined: e-me, eclass, Google Classroom, Microsoft Teams, Cisco Webex, Edmodo, Padlet, Skype and Zoom. Findings: Most platforms were rated as satisfactory in terms of perceived usability as measured by SUS. SUS scores were not found to be significantly related with participants' age, gender, private/public school, working relationship. Furthermore, openness to new experience and extraversion demonstrated the strongest positive correlation with perceived usability evaluation. Research limitations/implications: The current study used a sample of Greek teachers as participants, so the generalizability of results without considering cultural or organizational issues is of questionable validity. The Big 5 personality test is widely adopted; however, it seems that it does not capture comprehensively all possible dimensions of personality. Practical implications: Acknowledging the correlations between personality traits and perceived usability for each platform, teachers may now choose the most user-friendly one depending on the personality traits. Designers can adapt their systems to meet users' needs accordingly. Moreover, the reported results provide a frame of reference for the respective organizations and companies to compare the quality of user experience of their products and services. Thus, development costs of an e-learning platform/tool can be reduced accordingly. Social implications: Text. Originality/value: Perceived usability of a technological system affects the way users interact with it and consequently the whole learning experience. Thus, factors which may affect perceived usability and, in turn, the learning outcomes are of paramount importance and should be exhaustively examined. Giving that personality affects or is related to, other parameters related with technology (technology adoption, perceived and actual use, acceptance, interaction, perceived ease of use), this study addresses a significant research gap and sheds light to the before-mentioned issues.

Perceived usability affects greatly student's learning effectiveness and overall learning experience, and thus is an important requirement of educational software. The System Usability Scale (SUS) is a well-researched and widely used questionnaire for perceived usability evaluation. However, surprisingly few studies have used SUS to evaluate the perceived usability of learning management systems (LMSs). This paper presents an empirical evaluation of the SUS questionnaire in the context of LMSs' perceived usability evaluation. Eleven studies involving 769 students were conducted, in which participants evaluated the usability of two LMSs (eClass and Moodle) used within courses of their curriculum. It was found that the perceived usability of the evaluated LMSs is at a satisfactory level (mean SUS score 76.27). Analysis of the results also demonstrated the validity and reliability of SUS for LMSs' evaluation, and that it remains robust even for small sample sizes. Moreover, the following SUS attributes were investigated in the context of LMSs evaluation: gender, age, prior experience with the LMS, Internet self-efficacy, attitude towards the Internet and usage frequency of the LMS.

The present article examines the relationship between student personality, use of social media and their academic performance and engagement. Specifically, this article examines the relationship of students' Facebook (FB) use and personality characteristics using the Big Five Personality Test. This is focused on (a) student engagement; (b) time spent preparing for class; (c) time spent in co-curricular activities; and (d) academic performance. 204 higher education students participated in the study. Results illustrate that FB time was significantly positively correlated to student engagement and time spent preparing for class. Sharing links activity was positively correlated with student engagement and playing FB games with time spent preparing for class. However, sending private messages and status updates were significantly negatively correlated with student engagement and time spent preparing for class. Also, viewing videos was negatively correlated with time spent in co-curricular activities. Chatting on FB and viewing photos found to be the most popular activities. Moreover, students' extraversion, conscientiousness, openness to experience were positively correlated to student engagement. In addition, extraversion had a positive relationship with time spent in co-curricular activities, although agreeableness had a negative relationship. Implications of the study for the instructors and the students are also discussed.

The influence of students' non-cognitive characteristics on their learning performance constitutes a significant but rather unexplored topic. The goal of the research presented in this article, is to examine the relation between the students' personality characteristics (as measured using the Big Five Personality Test) and their learning outcome in the context of four framed wiki-based learning activities. 368 university students participated in the studies. Meta-analysis of results indicates that learning gain was significant negatively correlated with one of the five basic personality dimensions, namely Extraversion. Also, agreeableness was significant positively correlated with learning gain. Moreover, conscientiousness and emotionally stability were significant positively correlated with logged wiki edits that students made in this activity. It is argued, and discussed, that results from such studies can lead to useful conclusions regarding the design of appropriate activities and the creation of more effective collaborative teams in the context of wiki-based web activities.

A considerable interest in using Web 2.0 technologies such as wikis in education has been observed recently. Despite the advantages of the wiki technology, a number of questions concerning design of appropriate activities and their learning effectiveness remain open. In this paper, we present the results of three activities involving first-year university students using wikis to learn basic concepts related to information technology. Three activities of different classes were designed and delivered to the students using the framework proposed by West and West (2009). In all studies, a one-group pretest-posttest design was adopted. Results illustrated significant improvement in learning outcomes, particularly for students with low initial performance. The average students' questionnaire score jumped from 39.0/100 to 57.3/100. No significant effect of both students' role in the activity and their school stream on learning gain was observed. Finally, regardless of the activity's class and learning goal, a persistent pattern of high learning gain was observed.

Usefulness and ease of use proved to be key determinants of the acceptance and usage of e-learning. On the contrary, little is known about students' perceptions in a blended learning setting. In this paper, the Technology Acceptance Model (TAM) was utilised, in order to investigate Greek university students' attitudes toward blended learning. The goal of the study was twofold. First, to investigate whether the students' perceptions in a blended learning setting were comparable with other studies reporting perceptions in the context of distant learning. Second, to investigate variation in students' perceptions before and after actual system use. A sample of 130 students before actual system use and 102 students after the end of the semester was used. As derived from the model analysis using partial least squares, the e-learning system was well accepted and the majority of our hypotheses were confirmed. The most notable difference between pre- and post- use scenario was that perceived usefulness did not prove to have a significant effect on behavioral intention before system use, whereas, in the end, it appeared to be significant. The results are compared with similar studies focused on e-learning acceptance. The implications, both for the designer of a blended learning course as well as for the educational community, are also discussed. (Contains 8 tables and 2 figures.)

Digital storytelling is an advantageous practice for older adults. Although researchers have widely studied the effects of various recording media on users, including even their feelings of loneliness, to the best of our knowledge, there is no study that distinguishes and compares those effects within the digital storytelling process. In this exploratory case study, we tried to gain further insights into older adults' technology-mediated storytelling, the interactions, and the outcomes that different kinds of recording media have on users. Therefore, three storytelling components (paper notebook, voice recorder, and web platform) were used to probe their usability and emotional outcomes on five pensioners in Greece. Semi-structured interviews and questionnaires, among others, were implemented for data collection. According to the results, there was a variety of benefits and shortcomings for each tool. However, the web platform had a clear effect on decreasing users' loneliness. Implications and future work on digital storytelling are discussed. [ABSTRACT FROM AUTHOR]
