The objective of this study was to examine the effectiveness of blended physics laboratory experimentation on pre-service physics teachers' (PSPTs') understanding of the nature of science (NOS) during an electricity and magnetism laboratory course. The study used a non-equivalent comparison group using a pre-test-post-test quasi-experimental…

This study evaluates the experimental tasks of the Ethiopian grade 12 chemistry textbook vis-à-vis coverage of the essential components of science process skills (SPSs) using content analysis. All the procedures in an experiment were analyzed using rubrics of the inquiry-based task analysis inventory (ITAI) instrument. This instrument was based on…

This study examined the effect of blended laboratory experiments on pre-service physics teachers' (PSPTs') attitudes toward physics laboratories. The research design was a quasi-experimental pre-test and post-test comparing groups. Participants were 63 2nd-year PSPTs' enrolled in a physics diploma program from three colleges of teacher education.…

Accidents occur in laboratories due to a lack of proper knowledge regarding laboratory safety measures, perilous attitudes, and unacceptable laboratory practices. This study assessed the chemistry laboratory safety knowledge, attitude, and practice (KAP) of teachers and laboratory technicians in secondary schools of South Wollo, Ethiopia. The…

Although laboratory work is considered a significant factor in helping students develop their science process skills and cultivate alternative knowledge construction, there are still gaps in the selection, integration, and implementation of the basic elements in physics laboratories. In this study, three modified guided discovery and conventional…

The present study assessed the challenges to implement laboratory teaching in selected Preparatory Schools, North Shewa Zone. The result of this study showed that although laboratories for each subjects were present (100%) in all districts, lack of professional skills (50% in biology, 64.5% in chemistry and 61.5% physics), lack of materials (78.6%…

The impact of Physics laboratory on students was carried out among senior secondary school students offering Physics in Ethiope West Local Government Area of Delta State using descriptive survey. Five public schools were random-even samplying technique was adopted for precision. Fifty questionnaires were distributed to students in each school,…

There is a rising trend to provide low-cost laptops to children in developing countries. Notwithstanding strong claims about the educational effectiveness of these programs, there is very little systematic evidence. Given the level of modernization and the teacher-led learning environment in developing countries, the usage of laptops in such…
