Adding illustrations to texts might improve students' science achievement. This meta-analysis of 121 effect sizes from 63 studies of 7,621 students across five decades determines both the overall effect and moderators that account for differences across studies. Our random-effects model shows a positive effect of adding illustrations to texts on…

The low outcome of IPA ("Ilmu Pengetahuan Alam"/Science) learning in the Ecosystem topic is a problem in this research so that the use of the STEM learning model is expected to improve IPA learning outcomes. The population in this study was SD Negeri 2 Kotabunan sampled using a cluster random sampling technique and 20 students in Grade…

Science education is crucial for students as it fosters critical thinking, problem-solving skills and a deeper understanding of the natural world. The present study explored factors beyond the classroom that impact students' science academic performance (SSAP) at secondary schools. Based on research questions and literature, three hypotheses were…

Gross anatomy is a challenging pre-clinical course in medical school. A lab combined with lecture adds extra pressure, especially if students do not have prior anatomy exposure. One possible strategy to alleviate academic stress within anatomy is to designate table leaders. Some universities implement a rotating leader over the course of the…

The present research is an examination of Augmented Reality (AR) applications in Science Education using the Multi-complementary Approach (McA). This incorporates multiple analyses: i) Pre-complementary: meta-analysis and meta-thematic analysis, ii) Post-complementary: an experimental design with a pre- and post-test control group and iii)…

Students' performance in introductory physics at a university in Ghana was assessed over three academic years. The study covered two physics courses delivered to first-year students at the university. Two factors--access to tutorial sessions delivered outside of lecture times by teaching assistants and access to a formula sheet during the…

This research presents a meta-analysis of studies examining the relationship between recreational physical activity and children's performance in STEM (Science, Technology, Engineering, and Mathematics) subjects, with a specific focus on math and science. While previous research has established a positive correlation between physical activity and…

Women, especially Black and Latina women, are marginalized in physics, including in high school classrooms. Recognition is one of the ways women and girls experience marginalization in physics. This dissertation is comprised of three distinct but related studies examining how students experience recognition in an AP Physics 1 classroom. The first…

This study surveyed 19 chemistry teachers' stoichiometry pedagogical content knowledge (SPCK) in Ijebu Ode local government area of Ogun state, Nigeria using Malcolm's Physical Science Teachers' SPCK test. The qualitative data were transformed to scores, which revealed the level of chemistry teachers' knowledge of students' prior knowledge,…

The ability to extract structural information from a drawing of a molecule is key to being successful in organic chemistry. One source of difficulty for novices in interpreting structures is that hydrogens bound to carbon are represented implicitly in the often-used line-angle structures. Other representations that explicitly show hydrogens, such…

Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

Chemistry is an essential subject for most science-based undergraduate courses in universities; as such, it is a basic requirement for secondary school students aspiring to study science-related courses in universities. However, the subject has historically been linked to high failure rates and underperformance of students in secondary school…

Introduction: As technology progresses, individuals will be increasingly expected to solve digital tasks. At the same time, many worry that a high use of connected devices will reduce young people's ability to perform with accuracy long cognitively challenging tasks online. Methods: We examine whether 15-year-old students' ability to accurately…

Even though virtual labs help students learn science content, little is known about how well students can later apply this learning to other contexts or tasks when compared to students who performed physical labs. The goal of this study was to understand how students who perform physical versus virtual labs were able to later apply what they learn…

The Instrumental Analytical Chemistry course, taught in the fifth semester across several programs at the Faculty of Exact Sciences of the National University of La Plata, places a significant emphasis on high-performance liquid chromatography (HPLC). This versatile analytical technique is essential for the separation, identification, and…
