Explainable recommendation, which provides an explanation about why a quiz is recommended, helps to improve transparency, persuasiveness, and trustworthiness. However, little research examined the effectiveness of the explainable recommender, especially on academic performance. To survey its effectiveness, the authors evaluate the math academic performance among middle school students (n=115) by giving pre- and post-test questions based evaluation techniques. During the pre- and post-test periods, students were encouraged to use the Bayesian Knowledge Tracing model based explainable recommendation system. To evaluate how well the students were able to do what they could not do, the authors defined growth rate and found recommended quiz clicked counts had a positive effect on the total number of solved quizzes (R=0.343, P=0.005) and growth rate (R=0.297, P=0.017) despite no correlation between the total number of solved quizzes and growth rate. The results suggest that the use of an explainable recommendation system that learns efficiently will enable students to do what they could not do before.

This study substantiates the feasibility of implementing Web 2.0 services in practical educational activities and classifies the main types of Web 2.0 services adaptive to educational goals. A survey of 58 teachers from the First Moscow State Medical University, Kuban State Technological University, the Herzen State Pedagogical University of Russia, and Yelabuga Institute of Kazan (Volga Region) Federal University was conducted; their pedagogical experiences interacting with Web 2.0 services were considered in order to provide effective technological support for educational interactions in the context of distance learning in the era of COVID-19. The survey results showed that the most popular Web 2.0 services teachers use in distance learning include social networking services and virtual meeting and conference services. The study confirmed that using Web 2.0 services in educational processes can ensure high-quality digital pedagogy.

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.
