The collaborative learning approach as a universal teaching strategy is widely used in online learning. It is proven that the group leader has an important impact on group collaborative knowledge construction in online collaborative learning (OCL). However, limited research is available on how leadership styles influence a group universal teaching strategy is widely used in online learning this study, the authors adopted lag sequential analysis, epistemic network analysis, and social network analysis to explore the influence of divergent and convergent leadership styles on cognitive engagement in OCL groups. Compared with convergent leadership, divergent leadership strengthened online collaborative cognitive engagement through significant organizer and manager roles, triggered high-quality cognitive behavior transformation within the group, and promoted the balanced development of learners' cognitive structure.

This study aimed to examine the teachers' humanistic role in terms of integrity, dignity, and freedom in online classes, and its effect on mathematics learning achievement. The cross-sectional survey design was carried out by taking 2260 students from school to tertiary levels in Nepal during the COVID-19 pandemic. T-test, ANOVA, and hierarchical regressions were the major statistical techniques used to yield the results in the research. The results showed that access to the internet, grades/levels, and availability of digital devices are significant in the practice of the humanistic role of teachers and students' learning achievement. Additionally, many factors such as teachers' equality and fair treatment, expression of negative emotions, and displaying energy and enthusiasm in teaching-learning activities, interest in students' well-being, extended moral support, positive attitude, and understanding of pressures and limitations of students are significant predictors in the achievement of mathematics.

Massive open on-line courses (MOOCs) are effective and flexible resources to educate, train, and empower populations. Peer assessment (PA) provides a powerful pedagogical strategy to support educational activities and foster learners' success, also where a huge number of learners is involved. Item response theory (IRT) can model students' features, such as the skill to accomplish a task, and the capability to mark tasks. In this paper the authors investigate the applicability of IRT models to PA, in the learning environments of MOOCs. The main goal is to evaluate the relationships between some students' IRT parameters (ability, strictness) and some PA parameters (number of graders per task, and rating scale). The authors use a data-set simulating a large class (1,000 peers), built by a Gaussian distribution of the students' skill, to accomplish a task. The IRT analysis of the PA data allow to say that the best estimate for peers' ability is when 15 raters per task are used, with a [1,10] rating scale.

The current study aims to analyse school leaders' understanding and expectation of, and support for, online teaching and learning during and after the outbreak of the COVID-19 pandemic. Based on the theory of reasoned action (TRA) framework, the authors designed a questionnaire and collected 319 responses from school principals about their views on online teaching and learning. Structural equation modelling revealed that principals' understanding was significantly associated with their expectations and support. Together with a thematic analysis, this study indicated that school principals understood online teaching and learning. The most expected item was students' ownership and access to a suitable device for online learning. Principals were willing to support students' self-regulated learning through online teaching. They appealed for more support for the infrastructure needed to ensure teachers' and students' privacy and security in online teaching and learning. They had suggestions for teacher development to tackle learner diversity in the online mode.

Massive open online courses (MOOCs) could have been leveraged to bridge the education accessibility inequality gap in many developing countries, however many of the MOOCs platforms are developed to work in areas with good internet connections and high bandwidth leaving many rural areas excluded. The goal of this study was to develop a MOOCs model for areas with low bandwidth in developing countries. Literature search of technology implementation factors was carried out from which a conceptual model was designed. Using design science approach, the conceptual model was based on to developed an artifact of MOOCs platform that could be used in areas of low bandwidth. The artifact was evaluated using data collected from learners of tertiary institutions in South Africa. Results indicated that the developed artifact is suitable for use in areas of low bandwidth and that the model is a good guideline to the implementation of MOOCs platforms.

This paper reports on usage and impact on learning achievements of a dashboard developed to help monitor self-regulated learning behaviours in an online professional development path. The design of the path as well as of the dashboard were grounded on a pre-existing conceptual framework distinguishing between four different types of self-regulated learning behaviours taking place in professional learning networks and underpinning professional practice sharing. One of the objectives of the path was to promote such behaviours among participants, and the dashboard was designed to support their self-monitoring. Data were collected through usage log files analysis, a survey, and pretest and posttest. The results shed light on participants' actual usage of the dashboard, their opinion regarding its usefulness in relation of its capability to measure and support their SRL processes, and the dashboard's actual impact on their learning achievements. Moreover, some limitations in the current configuration of the dashboard emerged, which can guide further development.

Gamification becomes an important and widely used instrument in online learning, and it affects users' experience. However, recent research on the interaction between a user and technology, in the online learning platform, tends to study gamification separately. This paper aims to overcome the research gap, exploring the relationships between user engagement, platform affordances, and gamification in online learning. An online survey was conducted among the participants (N=375) studying with Skyeng (commercial online platform for learning English). The data was analysed with factor and regression analysis. The results demonstrated four major platform affordances: technology credibility and usability, adaptability of course tasks, phasing and intermittence and external reward. Among the four, technology credibility and usability was found to be the most influential predictor of user engagement in online learning. External reward, as an affordance, drawn from gamification elements, has the smallest contribution to user engagement. However, the study proves the suitability of perceiving gamified elements as affordances by platform users. The research provides conceptual and empirical grounds for studying gamification elements as one of the affordances in online learning and outlines further directions to explore these connections.

The breakout of the coronavirus disease has brought about a seismic shift in the daily lives of people worldwide. Educational institutions have been temporarily closed, and different types of lockdowns and social distancing approaches have been applied in countries around the world to delay the spread of the disease. This study investigates the determinants influencing university student intentions and use of electronic learning during the pandemic. Data were collected online from 229 respondents in different academic disciplines at various Saudi Arabian universities. The findings revealed that two factors positively affected students' behavioral intention to utilize electronic learning: trust and performance expectancy. Moreover, the findings showed the significance of facilitating conditions and behavioral intention on students' use of electronic learning during the lockdown. The study findings provide some important practical insights on how curriculum and pedagogy should be modified by adjusting learning standards and assessment tools.

As a supplement to face-to-face teaching, small private online courses (SPOCs) have become increasingly popular in higher education. Nevertheless, there is a lack of research on behavioral patterns in the university SPOC. This empirical study investigates the behavioral patterns of 306 undergraduate students taking a degree course partially taught through a university learning platform. Results suggested that task-oriented behaviors accounted for most of the online learning processes. The login behavior was the most significantly correlated with learning outcomes, followed by student engagement with learning activities. The authors found that students' engagement levels had a statistically significant impact on their learning outcomes. Additionally, the high-achieving group demonstrated higher activity levels in performance- and objective-driven activities. The low-achieving group encountered some difficulties in self-regulated learning.

This article describes the design and application of a computer-based system for simultaneously teaching Korean, English and Japanese languages in a classroom setting using knowledge visualization techniques to show the relationships between vocabularies, grammars and meanings. The system consists of a knowledge database of Korean, English, and Japanese which is then uploaded into the teaching module. Visualizations of this information in the form of knowledge maps based upon generally accepted rules of knowledge map can then be displayed and contrasted using the system interface to enter user queries. The system is then tested in a blended classroom of native Korean speakers. Data on student learning experiences are then gathered by means of a questionnaire and analyzed in order to assess the overall success of knowledge acquisition in this setting. Our findings show that this system evokes a personal initiative in the learning process, facilitates communication between teachers and learners, and supports the rapid acquisition of multilingual knowledge.
