This project engaged Ghanaian secondary pupils in authentic science and engineering activities by using model biodigesters that reduce organic waste and produce biogas and fertiliser. The pupils' activities paralleled scientists' activities, such as asking research questions and designing experiments. Our study included two cohorts of Ghanaian…

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…

Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

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…

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…

This action research case study explored the ability of three high school chemistry students to grow in their understanding of nature of science (NOS) during its explicit-reflective inclusion in two unit chapters on bonding (ionic compounds followed by covalent molecules). Students completed a pre, post and delayed Views of Nature of Science Form…

Every three years, the Organisation for European Cooperation and Development evaluates the scientific competence of European students. Recent results have demonstrated that scientific competence in Spain is somewhat underdeveloped, which underscores the need to apply educational methodologies that favour the development of said competence. This…

This study aimed to: 1) assess the impact of a STEAM education learning package on grade 10 students' science process skills, 2) evaluate its effect on their learning achievement concerning the physical properties of materials, and 3) gauge the students' satisfaction with the learning package. The participants were 13 grade 10 students from a…

Concept inventories are widely used in physics education research, yet numerous studies show that concept inventories measure dramatically different learning gains in different demographic groups. Prior studies show that the performance gaps between demographic groups are already present in their preinstruction responses, suggesting that the…

This study investigated whether the Key Concepts in Science Project influenced the pedagogical development of Natural Science teachers. Grounded in social constructivism, emphasising collaborative learning and hands-on interaction, the study employed qualitative methods to collect empirical data. Through photographic evidence, field notes, and…

In this quantitative study, we explored learners' intrinsic motivation towards three different experimental physics educational activities offered by our department to upper-grade high school students. The inspected activities were lecture demonstrations, a science show, and hands-on practical work. The respondents were Czech high school students…

Herein we describe an accessible and safe at-home experiment to separate lycopene from tomatoes via liquid-liquid extraction. As a qualitative experiment, it is a canonically elementary instance for high school students to digest the conception of miscibility, immiscibility, and density difference of the two solvents. This experiment was performed…

Integrating virtual laboratories (VLs) with science education promotes inquiry-based learning by providing an interactive, dynamic environment in which students actively engage with scientific concepts. While previous research highlights the effectiveness of VLs as tools in the IBL process, few studies have embedded the entire inquiry process…

In science education, educators frequently encounter the challenges of inadequate resources, equipment, and pedagogical strategies when planning and executing science projects in classrooms. To address this pervasive issue, forty-one science teachers participated in a training workshop to acquire expertise using Arduino microcontrollers and…

Organic chemistry is a cognitively demanding subject with persistently low student achievement. This review aimed to identify instructional strategies and educational technologies used to improve learning outcomes in organic chemistry across educational levels and learning environments. A systematic review of 40 experimental studies (2014-2023)…
