Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

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…

The basics of organic chemistry nomenclature were introduced in a laboratory organized in a nonformal environment such as a science festival. The laboratory, divided into three distinct but interconnected activities, was aimed not only at secondary school students but also at lay people. The intent was to explain the importance of associating a…

Poor performance of students in chemistry shows that they are having difficulties in learning, mastering the content, and applying what they have learned in examinations. The purpose of this study was to find out the difference in (a) retention of information by students taught nuclear chemistry using the culturo-techno-contextual approach (CTCA)…

As part of the current UK GCSE science curriculum, pupils need to use their understanding of science to answer questions about a series of core experiments. Problem-solving and applying knowledge to new situations is fundamental in enabling students to progress in science; however, many learners struggle to develop these skills. This can lead to…

The current study ascertained the influence an instructional module had on enhancing students' understanding of chemical reactions and acid-base topics. The sample size for this study consisted of 197 students, including 101 in an "experimental" group and 96 in a "control" group, selected from schools in two Districts…

In this research, it was aimed to determine the effect of Simulation-Supported Prediction Observation Explanation (SSPOE) activities related to solid and liquid pressure on the conceptions of learning physics of 10th grade students. In the research, a quasi-experimental design with pretest-posttest control group, which is one of the quantitative…

Despite its intellectual and philosophical significance, cosmology and general relativity (GR) remain largely inaccessible to high-school physics teaching because of the advanced conceptual and mathematical prerequisites to master these topics. Integrating them into upper secondary physics teaching, outside specialized courses, poses a significant…

This case study examines students' perception, motivation, and learning gain of a teaching unit featuring wireless sensors as tools to collect scientific data in the classroom. Students analyze data using the corresponding cellphone app, communicate findings to the class, and learn about a changing environment. Wireless sensors are produced for…

Argumentation is fundamental to science education, both as a prominent feature of scientific reasoning and as an effective mode of learning--a perspective reflected in contemporary frameworks and standards. The successful implementation of argumentation in school science, however, requires a paradigm shift in science assessment from the…

This article focuses on the learning of the Lewis representation at the transition from high school to university, in France. Indeed, this notion is taught both in high school and in the first year of higher education but with different methods, which seems to hinder the learners. In this work, we observe 11th grade and higher education classes…

Learner-centered instructional practices, such as the metacognitive strategies scaffolding the problem-solving method for Biology instruction, have been shown to promote students' autonomy and self-direction, significantly enhancing their understanding of scientific concepts. Thus, this study aimed to elucidate the importance and procedures of…
