This cross-sectional, observational study examined how school-level academic performance and enrollment in the physical sciences (Earth science, chemistry, and physics) mediate the predictive value of socioeconomic status on graduation rate in U.S. high schools. Data were collected from N = 555 schools (475,539 students) that reported enrollment…

Improving student achievement is one of the most important components of learning, and it is influenced by several variables, including academic resilience, self-regulation, and students' perceptions. This study examined how high school academic resilience, self-regulation, and students' perceptions affect their academic achievement in chemistry…

Chemistry education in Rwandan secondary schools faces challenges, especially after the adoption of a competence-based curriculum that prioritizes student-centered learning. Traditional teacher-centered approaches often result in poor student performance. This study investigates the impact of structured group discussions on chemistry achievement…

Noticing the inconsistency in previous studies of gender differences in learning physics, it was determined to check whether a gender gap exists in a relatively large sample of competitors (N = 12,966) from Serbia. The aim of the research presented here was to analyze the achievements of male and female lower secondary school students, competitors…

A didactic sequence is proposed using an infrared puzzle and a didactic questionnaire for the teaching-learning of infrared spectroscopy at the upper secondary level. The didactic sequence that was designed was implemented in person in the subject of Chemistry IV at the high school level, corresponding to the sixth semester of the curriculum of…

A new generation of science curriculum materials is being developed and made widely available across K-12. These materials, along with their associated professional learning, are expected to play a pivotal role in transforming science instruction to meet the vision of A Framework for K-12 Science Education and the performance expectations of the…

Student perceptions toward homework assigned in general chemistry courses was investigated in this study. The study participants were required to complete homework assignments using two different online systems, ALEKS (adaptive-responsive system) and Sapling (traditional-responsive system). An online survey investigating their general perceptions…

This research integrates context-based learning and modelling. It presents a teaching-learning sequence (TLS) about the dissolution of gases in liquids using carbonated drinks as the context. The impact of the TLS is analysed in a longitudinal short-term study involving two groups of learners aged 13-14 years old (n=53). The results led us to…

Science education is essential for sustainability and prosperity. However, students from rural communities, arguably the future custodians of our environment and significant drivers of our economies, underperform in science education. In Australia, rural students generally lag behind metropolitan students in science achievement and engagement.…

This study investigated Chemistry students' performance and retention (knowledge and understanding, knowledge and application, perception and attitude) in Organic Chemistry in three Senior High Schools (SHSs) within Tamale Metropolis in Ghana. Collaborative learning models were employed as intervention strategies. Quasi-experimental design was…

The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

The aim of the study is to examine the relationship between the learning styles of classroom students in the force and energy unit and their scientific process skills. In the study, pre-test and post-test weak experimental design without a control group was used. The research was carried out in 2 different secondary schools in the central district…

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…

Educators have struggled with maintaining student engagement in science, especially as students transition from primary to middle school and upper grades (Vedder-Weiss & Fortus, 2012). A recent push in science education has been the adoption of the Next Generation Science Standards (NGSS), released in 2013, whose development was guided by…
