Development of Design Principles of Group Awareness Tool for Facilitating Computer-supported Collaborative Argumentation

As one of the forms of collaborative learning, collaborative argumentation can improve students’ argumentation skills, promote effective content learning and cultivate critical thinking. Especially in the field of Computer-supported Collaborative Learning (CSCL), such as conflicts between group members, free-riding behavior, and unequal participation occur frequently. At the same time, in the CSCL environment, it is difficult to coordinate one’s actions with other group members’ actions. These problems are mainly caused by learners who cannot obtain group awareness information about accompanying learners and the current group. Therefore, this study according to the previous research, the initial design principles and initial specific guidelines for the group awareness tool were identified. After that, three educational technology experts reviewed the initial design principles and guidelines. The modified specific guidelines were applied to the two-week classroom teaching of 45 first-year students in a class. In addition, a learners’ response survey was conducted on the students who actually participated in the computer-supported collaborative argumentation activities. Finally, the results of questionnaire surveys (n=45) and interviews (n=5) were analyzed, and the final specific guidelines were developed. According to the research results, collaborative argumentation based on group awareness tool solves the problem that general collaborative argumentation activities can’t obtain timely information on the cognitive, behavioral, and social awareness of accompanying learners and the current group study situation. It can continuously maintain their study motivation and promote interaction among learners to improve the quality of computer-supported collaborative learning.

Context-relevant strategies for ICT integration in teaching and learning science subjects in Tanzania secondary schools

Information and Communication Technology (ICT) can improve science teaching and learning. However, understanding the contexts in which ICT is intended to be integrated for its effectiveness is limited. Therefore, the current study explored context-relevant strategies and challenges for ICT integration in the teaching and learning science subjects in secondary schools in Tanzania. Exploratory sequential design under mixed methods guided the study's conduct. 52 participants (45 science teachers, six heads of schools and one municipal education officer) were purposefully and conveniently involved. Data were collected in two phases: 1st phase was qualitative data through in-depth interviews, 2nd phase was quantitative data through a questionnaire. Thematic analysis guided qualitative data analysis where MS Excel in the form of pivotal charts were used to present the frequency of the responses. SPSS version 27 guided the quantitative data analysis, presenting the output descriptively. Participants presented various context-relevant strategies, including capacity building for teachers, building and equipping computer labs with ICT facilities, maintaining and repairing defective computers, deploying educational technology experts, and making ICT compulsory at all levels of education. On the other hand, participants identified a lack of ICT facilities, limited ICT training opportunities, and digital content as context-relevant challenges for ICT integration in science teaching and learning. The study recommends rigorous pre-service and in-service teacher training programmes on ICT pedagogical integration for science teaching and learning based on these findings. Again, we recommend the improvement of ICT infrastructure in schools to enhance the availability, access, and use of science teaching and learning. The study concludes that if sufficient infrastructures are available and science teachers are equipped with ICT knowledge, teaching and learning of science subjects will be effective.
