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…

The main purpose of the study was to investigate the effect of Jigsaw-4 problem-solving instruction on preservice physics teachers' (PSPT) problem-solving skills in the college of teacher education in the Southern nation nationality region of Ethiopia. The study involves 136 first-year PSPTs who are attending their preservice teacher education…

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…

This study aimed to uncover the ontological orientations of educators' sense of the atom of Kotebe Metropolitan University (KMU), Ethiopia. Thus, an interpretative case study design was employed, with the analytic approach of grounded theory, due to the importance of atomic ontology as a case and the need for an in-depth analysis of their thinking…

The study aimed to assess the effectiveness of the Predict-Explain-Enact-Observe-Reflect (PEEOR) instructional strategy on general science students' conceptual understanding and motivation in the topic of motion and force. The research employed a pre-test post-test quasi-experimental design. The sample consisted of 107 general science summer, year…

The study assessed the influences of science teachers' sex and teaching experiences on their gender-responsive pedagogy (GRP) practices of general secondary schools of North Wollo Zone, Ethiopia. It used a case study design and considered science department heads and school principals, and students as data sources comprehensively and purposively,…

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…

In this study, we explored undergraduate chemistry education at Kotebe University of Education (KUE) in terms of the ontological orientations, patterns and source domains of educators' and undergraduate students' sense of the atom. Due to the ambiguity and controversy regarding atomic ontology as a case of interest and the requirement for a…

The study aimed to investigate the effect of computer simulation and animation-integrated instruction on preservice science teacher trainees' conceptual understanding and retention of acid-base chemistry and stoichiometry. A quantitative approach with a pretest-posttest-delayed test quasi-experimental design was used. In the study area, there were…

This case study presents the analysis of teacher-student interaction in physics classrooms. The participants of the study were three physics teachers and 131 students from three upper primary schools (Grades 7 and 8) of Ethiopia. Data for the study were collected through observation of eight video recorded physics lessons. The analysis of videos…

The impacts of a technology-integrated formative assessment technique on students' conceptual and procedural knowledge in studying chemical equilibrium are studied in this study. To attain the purpose, a quasi-experimental pretest-posttest strategy nested with a qualitative study method was adopted. The study has three groups: two experimental and…

In physics education, assessments address various forms of scientific knowledge. Most of the existing test instruments emphasise the assessment of content knowledge. These tests fail to measure the epistemic aspects of science. Thus, assessing epistemic knowledge is a theme that demands investigation. This study applies Rasch analysis to help…

The main purpose of this study was to examine teachers' self-perceived practices of context-based science teaching and learning in science classrooms. To achieve this purpose, a cross-sectional survey design was employed. The data were collected from 360 upper primary science teachers in East Gojjam Administrative Zone, Ethiopia. A multistage…

Jigsaw-IV Problem-solving method is innovative active learning instruction used to improve college student's learning. The main purpose of the study was to investigate the effect of Jigsaw-IV problem-solving instruction on preservice physics teachers' (PSPT) procedural knowledge in college of teacher education in the Southern nation nationality…

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.…
