The goal of this study was to assess students' level of conceptual understanding of chemical kinetics and equilibrium using topic-specific pedagogical content knowledge (TSPCK)-based instruction in chemistry grade 11 students. The research was a mixed approach that involved 159 grade 11 chemistry class students from Addis Ababa administrative…

The aim of this study was to compare the analytical thinking skills of the 8th grade students who received emergency distance and face-to-face education in a science course and to get student ideas concerning emergency distance education. An unequal control group model from the quasi-experimental models was used in the study. The study group…

Students' socioeconomic status (SES), school climate, and students' attitudes stand out as important factors that determine academic achievement. The current study investigated the relationship among SES, attitude toward science, school climate, and academic achievement comparatively in terms of countries. Trends in International Mathematics and…

Scientific literacy (SL) has been recognized as the main goal of science curricula documents around the world; however, comparative international curriculum research is limited, especially with Western and African countries. To fill this gap, this study aimed to compare the coverage of SL competencies with the components of knowledge, attitudes,…

In this quasi-experimental research, the effect of the inquiry-based 5E instruction on students' learning of the topic of the main subatomic particles forming the atom as well as on their level of motivation was examined. The sample for the study comprised 45 ninth grade students enrolled in two randomly selected classes at a public high school…

The purpose of the study was to determine the perceptions that senior high school (SHS) chemistry students, and teachers have about organic chemistry as well as to compare organic chemistry topics that are difficult for students and teachers. Simple random sampling (lottery) and purposive sampling methods were used to select a sample of 100 SHS…

The study examined the effect of context-based learning (CBL) and gender influence on chemistry students' acquisition of integrated science process skills (ISPS). Two research questions guided the study. This study used a quasi-experimental research design with a sample of 192 participants who had an average age of 15. Three instruments were used…

Ecological knowledge is one of the components of environmental literacy that refers to the ability of people to understand and apply acquired knowledge about ecology to achieve a grasp of how nature works and their interactions with the social system. This study aimed to determine pre-service science teachers' level of ecological knowledge in Cebu…

The learning characteristics of each student are different. Differentiated instruction considers individual differences, as such guides the learning journey rather than seeing these differences as a challenge. The purpose of this research was to compare the effects of differentiated instruction and 5E learning cycle in physics classes on the…

The study investigated the effects of graphic organizer (GO) and experiential learning (EL) with feedback on the mean achievement and students' critical thinking in Jos North Local Government Area of the Plateau State of Nigeria. A pre-test post-test quasi-experimental design was used. A sample of 75 students was drawn from the population of 1950…

Computational thinking (CT) is a problem-solving process and argued to be one of the more important skills for the 21st century. This study aimed to identify the effectiveness of the Science Module on achievement in science subjects. A quasi-experimental research design was used that involved 67 students in the first form in secondary schools…

We report on our experience with the implementation of project-based teamwork on nuclear energy with 14 ninth-grade students from a lower secondary model school and its assessment using two written questionnaires, which were answered by the students after the completion of the project. The first questionnaire elicited students' opinions about the…

Previous studies identified a learning progression on the concept of carbon cycling that was typically followed by American students when they progress from elementary to high school. This study examines the validity of this previously identified learning progression for a different group of learners--Chinese students. The results indicate that…

This study examined the effect of Programmed Instruction on students' attitude towards Structure of the Atom and the Periodic Table (SAPT) among mixed (co-educational) secondary schools of Butere district, Kakamega county, Kenya. The quasi-experimental research design was adopted, using the nonrandomized Solomon four-group as a model. The sample…

The main goal of environmental education is to improve environmental literacy, including not just more knowledge but also a better attitude toward the environment and a higher prevalence of pro-environmental behaviours. The Eco-School Program is considered the world largest environmental education program for schools, but it keeps growing without…
