The purpose of this study is to investigate students’ intention to use ICT and use behaviour for learning and research by extending the UTAUT model with Health Issues and satisfaction as mediating variables between ergonomics factors and intention to use ICT relationship. This study employed a survey, which used a questionnaire to elicit data from university students and quantitative approaches to address the study's objective. A total of 1500 questionnaires were sent out, 972 responses were received, and 955 of them were useful. To examine students' ICT usage, the researchers used partial least squares structural equation modelling. The findings suggest that performance expectancy, effort expectancy, social influence and health issues significantly influence students’ behavioural intentions to use ICTs. However, ergonomics factors negatively influence health issues. Finally, students ICT use behaviour was strongly influenced by behavioural intentions. The model explained 50.3% of students’ behavioural intention to use ICT for learning

This article presents the perception of 611 students from public universities in Mexico about online classes in pandemic times. Exploratory factor analysis was conducted. Vygotsky's contributions are taken, especially those related to emotional manifestations. It is concluded that the most important factor in this change is the emotions that are identified as an impulse to act during online classes, given the didactic and pedagogical components, resources, and supports for students that promote learning. This proposes a framework for considering the emotional aspects of positive engagement in students learning online. There is evidence of some balance between the advantages and disadvantages of online education. It also suggests that women perceive more negative emotions such as disappointment and frustration in the online education experience. The teacher, being a vicarious learning model, can innovate in education by promoting peripheral participation with other playful activities that involve abstract, applied, and situated learning.

Rapid development and adoption of mobile technologies including Mobile Instant Messaging (MIM) platforms have transformed teaching and learning practices over the past decade. This paper presents an analysis of how students used WhatsApp as an example of a MIM platform to organise their learning activities. Drawing on Rhizomatic Learning Theory (RLT), the study showed that WhatsApp supported students to navigate through a complex network of learning where knowledge was generated beyond the confines of the formal learning context. WhatsApp supported learners during the transition to remote learning that was introduced during the lockdown due to the Covid-19 pandemic. Further, WhatsApp use supported learners to cope well with new learning experiences and practices. The study offers insights into the perspective of learners on the use of technology during challenging and uncertain times. The insights can be useful for lecturers when developing technology strategies and teaching best practices during uncertain times.

An active learning group work course at “A” university in Japan is characterized by two-way interactions between students as well as between teachers and students. The spread of COVID-19 prompted a shift from in-person lessons to online synchronous lessons in 2020 and 2021. This mixed methods study analyzes data from a combined structured and open-ended questionnaire completed by 5,268 students. The results showed that online lessons were significantly more highly evaluated than face-to-face lessons in terms of enhancing students' understanding of student life, sense of belonging, expressing one's opinions and listening to those of others, and self-regulation of attendance and gaining an in-depth understanding of the course material. However, face-to-face lessons were preferred for small class sizes, interactions with students who have different ideas, and group learning activities. Open-ended responses indicated that conducting online classes via Zoom improved students' perceptions of group learning and interaction in this setting.

As a foundational approach in inferential statistics, hypothesis testing (HT) is considered as one of the most challenging topics for teaching and learning. A promising approach is through the consideration of students’ learning modalities, as demonstrated in vast applications; however, contentions that surround the use of learning modality in education exist in recent debates. The cause of this unrest is the lack of robust empirical evidence on the efficacy of learning modalities in education. Thus, this work attempts to contribute to this debate and investigates whether sensory modality does influence learning. It develops an approach for teaching HT to college students via learning modality. Results show that learning modalities have a positive impact on students’ performance on competencies in learning HT. Furthermore, it was found out that some learning modalities work together on learning specific competencies. Lastly, the task-dependency of learning modalities was observed in the results of the experiment.

The programming domain is a challenging field of study for most novice programmers. Novices have to learn different skills in the Programming 1 course at the same time. This study prepared and introduced a chatbot in the course. The chatbot emphasizes syntax and semantics, problem solving strategies, course details, and common programming syntax and semantics errors. The influence of the chatbot on students' learning in the Programming 1 course was determined by performing a survey and analyzing the final grades of the course. The survey results reveal that the chatbot approach was appreciated by both female and male students in the Programming 1 course. The chatbot helped novices in comprehending the fundamental programming concepts and understanding common syntax and semantic errors. The analysis of final grades shows that female students perform well in the medium and low achiever categories, and male students show better performance in the high achiever category.

The purpose of this study is to explore how social networks impact learners’ knowledge sharing in the context of a learning community. The findings indicate that the various networks collaboratively support learners’ knowledge sharing in a local community. A better social position gives rise to more networks and correspondingly more knowledge accessible to learners. The between-group ties such as residential committees are crucial for knowledge exchange through connecting various social networks. Social isolation impacts learners’ interactions with others. However, more networks do not necessarily lead to more advanced knowledge acquisition. Accessing social networks cannot guarantee that learners will successfully access substantial knowledge in other fields. Social networks targeting learners’ need influence learners’ interest in social networks.

Higher education (HE) in Kuwait suffers from high dropout rates, and one of the leading causes of this desertion is a lack of academic advising. Effective academic advising systems must fulfill its user’s needs and provide a positive user experience (UX), which allows users to successfully and effectively fulfill their goals. This study used quantitative and qualitative approaches to evaluate an electronic advising system (e-Advisor) used by the Public Authority for Applied Education and Training (PAAET). Survey data from 1,095 PAAET students were analyzed to determine students' perceptions and evaluate their experience using e-Adviser. The findings indicated that students were aware of the features and advantages of e-Advisor. Overall, the participants had a moderately positive impression of e-Advisor’s UX. The system’s attractiveness, efficiency, and perspicuity were rated slightly higher than its dependability, stimulation, and novelty. Moreover, female students’ perceptions of e-Advisors UX were significantly more favorable than their male counterparts.
