The study examined the effectiveness of concept mapping in improving students' academic performance using an embedded mixed-methods design. It involved Srinka Secondary School's grade 10 biology teacher, students, and department head in the study and gathered data from them by using biology achievement tests, interviews, and focus group…

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…

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 determined how chemistry instruction using technology affected student achievement and retention. To achieve the goal of the study, Solomon's four-group quasi-experimental research design was used. The one-way analysis of variance (ANOVA) and independent sample t-test were used to statistically examine the data. A one-way ANOVA analysis…

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…

Purpose: The purpose of this study was to investigate the impact of using a jigsaw learning strategy integrated with computer simulation (JLSICS) on the academic achievement and attitudes of students, along with exploring the relationships between them in the process of learning about acids and bases. Design/methodology/approach: The research…

Learner-centered instructional practices, such as the metacognitive strategies scaffolding the problem-solving method for Biology instruction, have been shown to promote students' autonomy and self-direction, significantly enhancing their understanding of scientific concepts. Thus, this study aimed to elucidate the importance and procedures of…

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 purpose of this study was to examine whether a simulation-integrated context-based 7E instructional strategy (SICBIS) could increase students' achievement in the chemistry of oxides, acids, bases, and salts (COABS) when compared to context-based 7E instructional strategy (CBIS), simulation-integrated conventional teaching approach (SICTA), and…

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…

This study examines how students' conceptual and procedural knowledge of chemical equilibrium is affected by technology-supported formative assessment (TSFA) strategies. This study's embedded/nested mixed method research design was used to achieve the study's objective. A random sampling method was used to choose the sample of two intact classes…

This study was aimed to investigate the effect of simulated analogical reasoning blended with group discussion method on secondary school students' physics achievement. A total of 120 grade 10th students from three different high schools found in Debre Tabor Town, Ethiopia was selected and assigned as three experimental groups randomly to be…

The purpose of this study was to explore grade eight students' views in terms of different scientific reasoning progress levels. To explore students' views, phenomenographic study was used. The qualitative analysis of students' interviews elicited three major themes of students' views about scientific reasoning progress levels: naïve, mixed, and…

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…
