This quantitative study using cross-sectional survey design was conducted to establish the prediction effect of locus of control on academic attitudes among secondary school science teacher trainees at a public university in Uganda. Data were collected from a census of 203 students using structured questionnaires comprising a biodata section, Locus of Control Scale and Academic Attitudes Scale. Analysis was done using SPSS, and information was presented in tables and later described. Results showed that the trainees used mainly external locus of control and had generally moderately negative academic attitudes. Locus of control significantly predicted academic attitudes (t = -2.595, p = .010). Further analysis revealed that there was a statistically significant difference in academic attitudes between students originating from rural areas and those from urban areas. It was concluded that the use of external locus of control shifted responsibility of academic issues from the students to other external causes which likely resulted in counterproductive view the science and hence negative academic attitudes among the students.It is recommended that trainees need to be educated before and during pre-service training to appreciate teaching as a noble profession, and that trainees with the right disposition should be selected at entry to preservice training so as to foster the needed changes in science and technology education for national socioeconomic transformation.

Many researchers have discussed this challenge toward adopting an appropriate approach to teach physics in the institution. Therefore, the study reviews the research articles towards multimedia in improving the knowledge delivery system of physics published in various standard databases/indexes. The study conducts a literature review based on five-stage methodology comprising of: (1) research article collection from the databases, (2) research article inclusion/exclusion norms, (3) reviewing the processed research articles, (4) analyzing the research articles to extract the information, and (5) inferring the extracted information to derive at the future research direction. The paper contributes to reviewing thirty-three research articles specific to the usage of multimedia towards improving the methodologies involved in teaching and learning physics. The core idea of this study is to extract the research gaps on the usage of multimedia in the current knowledge delivery system of the physics domain to provide future research directions. Further, a bibliometric analysis comprises co-occurrence of keywords, citation, and co-citation using VOSviewer software. It is followed by content analysis to analyze the research method and multimedia tool used. The study outcome shows that most of the existing work found is Quasi-experimental design-based or qualitative design-based. The study outcome also highlights various themes of accepted papers and research gaps on the usage of multimedia in the knowledge delivery system of the physics domain.

This study used a quasiexperimental, pretestpost-test control group design with PBL instruction as a teaching intervention. The participants of this study were 239 physics students from 19 secondary schools in Western Uganda. We analyzed data with SPSS v.23.0 using repeated two-way analysis of variance tests. We found that unlike the superposition of mechanical waves concepts, PBL effectively improves students' understanding of propagation, reflection, and standing waves more than the usual or traditional teaching method. Teachers were recommended to teach with PBL to assess students' difficulties to remedy them and uplift their understanding.

However, while the positive effects of diversity on students are apparent, few studies have examined possible negative challenges that diversity might have on students. Where most subject matter is taught via classroom lectures and the lecture material is presented by a speaker with a different accent than the student is used to hearing, does it make the material harder for the student to understand? On the other hand, could it increase the focus and engagement required by the students in the classroom, and in the process increase their understanding? In this vein, our research sought understand whether students’ learning of the subject matter hindered when they are taught material by a teacher with a different accent. To this end, we designed a simple experiment with a small group of u...

Design/methodology/approach – Using a mixed research methodology, this research documented CSR activities of 16 companies operating in Uganda. Data collection was guided by quantitative and qualitative methodologies (semi-structured interviews with CSR managers, plus non-participant observation of CSR activities and projects linked with MDGs). Triangulation was used to ensure credibility and validity of the results. For data analysis, the authors followed a three-stepwise process, which helped to develop a framework within which the collected data could be analyzed. For generalization of the findings, the authors were guided by the “adaptive theory approach”. Findings – Uganda will not realize any MDGs by 2015. However, CSR activities have the potential to contribute to a cross-section of various MDGs that are more important and relevant to Uganda when supported by the government. If this happens, realization of the MDGs is likely to be stepped up. CSR&#39;s potential contributions to the MDGs were found to be hindered by corruption and cost of doing business. Lastly, MDG 8 and MDG 3 were perceived to be too ambiguous to be integrated into company CSR interventions, and to a certain extent were perceived to be carrying political intentions which conflict with the primary business intentions of profit maximization. Practical implications – Governments in developing countries that are still grappling with the MDGs can use this research when devising collaborations with private-sector companies. These documented CSR activities that contribute directly to specific MDGs can be factored into the priority public-private partnership arrangements. Private companies can also use these findings to frame their stakeholder engagement, especially with the government and also when setting CSR priorities that significantly contribute to sustainable development. Originality value – This research advances the “Post-2015 MDG Development Agenda” suggested during the United Nations MDG Summit in 2010, which called for academic and innovative contributions on how MDGs can be realized even after 2015.
