Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…

This is the second of 2 reports that look at the results of TIMSS 2023 and Australia's performance. This report, Volume II, presents the results from the contextual questionnaires, and examines the home, school, and classroom contexts in which learning and achievement occur, as well as student attitudes. Each chapter focuses on different…

This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

This study explores how gamification enriched learning activities affect science learning in terms of achievement, attitudes and science learning skills. Fourty-three 6th grade students participated in the study which employed a quasi-experimental design that included an experimental group receiving science education through gamification…

This research aims to examine the self-regulation of students with different achievement levels toward science learning based on Zimmerman's model including three phases: forethought, performance, and self-reflection. The research was conducted based on the case study from the qualitative research method. The study group consisted of 12 students…

The ultimate aim of this research was to explore the contribution of teacher preparedness or readiness (in terms of their academic background, confidence in teaching science and career satisfaction) towards the achievement in science among Malaysian and Singaporean eighth-graders. The TIMSS 2011 international assessment of student achievement at…

Game-based learning has attracted great interest in science education as an effective way to increase student achievement. Most studies in this field have focused on digital or non-digital games. In the literature, some studies generally compare educational games with traditional teaching methods. More studies need to be conducted to compare the…

In this study, the effect of internet-based applications on the academic achievement, motivation, and awareness of Web 2.0 tools of 6th grade middle school students on "Matter and Heat" was examined. The study group consisted of 73 (experimental: 50, control: 23) 6th grade students from a public school in Istanbul, Turkey. The study was…

Ninth-grade students with learning difficulties typically underperform those without learning difficulties, particularly in an integrated geoscience course. Despite the growing demand for STEM careers, science remains challenging to understand and inaccessible to many, especially those with learning difficulties (Vavougios et al., 2016).…

This study aimed to investigate the effects of the argumentation-based inquiry (ABI) approach on the analytical thinking skills and academic achievement of seventh-grade students using a mixed method. It was conducted in a secondary school in the Western Black Sea region of Turkey with seventh-grade students from two classes during the fall…

Student' achievement in science can be affected by teacher subject matter knowledge, ineffective instructional methods, and lack of student engagement. Although all schools provide professional development opportunities, not all teachers choose to engage in a program that provides teaching and learning through experiential techniques for the…

This study developed and validated the Science Practice Scale (SPS) and investigated the implementation of scientific teaching practices by Grade 8 science teachers in Jordan. The responses of 235 8th grade science teachers who participated in the Trends in International Mathematics and Science Study [TIMSS] of 2019 were analysed using the Rasch…

This study examined the effect of using critical reading in scientific texts on students' academic achievement, sci-ence performance level and creativity. The study was conducted with 5th grade students in Eregli, Zonguldak during the 2017-2018 academic year. The study group consisted of a total of 34 students, 17 in the experimental group and 17…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science…

Teachers' professional development (PD) is considered to be a topic of interest in science education. This study examines the impact of professional development in science pedagogy (PD in PED) on students' achievement and how it influences teachers' instruction based on the Trends in International Mathematics and Science (TIMSS) 2019. The sample…
