<p style="text-align: justify;">Guided by the analytical framework in the current literature, whereby ten nature of science (NOS) aspects were targeted, this study aims at assessing the extent to which the three physics textbooks for Cycle 4 of Fundamental Schools in Burundi represent the NOS aspects. The quantitative embedded research design which combines the qualitative and quantitative to both the representations of text and images were applied to collect and analyses data. Three physics textbooks used in this study as textbooks I, II and III (grade 7 textbook, grade 8 textbook and grade 9 textbook) were purposively selected. 65 physics lessons were analyzed in three steps including exploring representations of NOS aspects, representations of NOS teaching approaches and accuracy and completeness of NOS aspects. Data were collected using a guide document analysis and a rubric of NOS scoring and were analysed descriptively. The findings found a considerable deficit of NOS aspects in the physics textbooks. The findings also revealed the critical situation where the few lessons poorly represent the NOS aspects and the majority of them do not include the aspects of NOS. Furthermore, this study suggests the in-charge of quality assurance to evaluate and deliberate on the accuracy and completeness of physics textbooks for Cycle 4 of Fundamental Education in Burundi.</p>

This study sought to establish the effectiveness of Computer-Supported Collaborative Learning in improving student’s electricity conceptions among secondary schools in Arusha City through the exploratory research design. The study employed the electricity conceptual achievement tests (pre-test and post-test) within 196 sampled Form Two students. Data was analysed descriptively. The pre-test mean and standard deviation were 38.082 and 16.75719 respectively while the post-test mean scores and standard deviation results were 59.745 and 17.39898, respectively. The study detected deficiency in the understanding of concepts in the non-participatory teaching methods used before the intervention. After the intervention through the CSCL approach, the variations were detected in that students' understanding of concepts in electricity improved. This means that when technology is incorporated, students’ conceptual understanding is enhanced. The study recommends teachers to use digital pedagogical approaches such as CSCL to bring about better learning results.
