Redox reaction is a core chemical concept. However, its abstract nature makes it very difficult for students. Students' conceptual structure reflects their mastery of concepts, which helps teachers implement targeted educational strategies. This study aimed to explore the conceptual structures of redox reaction held by students (grades 10 to 12)…

The COVID-19 epidemic adversely impacted chemical engineering experiments(CEEs). Students underwent online learning, i.e., software simulation of the CEE course, instead of laboratory learning. A questionnaire survey revealed that students exhibited low enthusiasm for online learning, showing that online courses cannot ensure learning quality.…

This paper describes and compares primary school students' perceptions of science learning skills in a teacher-centered approach (TCA) and in inquiry-based science fieldwork (IBSF). This comparison was prompted by primary school students' perceptions of science learning skills, which has recently gained momentum, and the Namibian primary schools'…

This study examines learners' issues in learning the preparation and qualitative analysis of salts topic from Malaysian chemistry teachers' perspectives. The researchers adopted a qualitative design and conducted semi-structured interviews with sixteen informants who have experience of teaching chemistry for more than five years. They were…

This study investigates if collaboration and the level of heterogeneity between collaborating partners' problem-solving scripts can influence the extent to which pre-service teachers engage in evidence-based reasoning when analyzing and solving pedagogical problem cases. We operationalized evidence-based reasoning through its content and process…

This study used three previously validated instruments, namely Science Academic Hardiness (SAH), Students' Conceptions of Learning Science (COLS) and Science Learning Self-Efficacy (SLSE) on 431 Singaporean students. Using structural equation modeling, results showed that the SAH commitment dimension a positive predictor explaining both the…

Out-of-school labs (OSLs) aim to foster students' interest in and knowledge about scientific ways of thinking and working by engaging them in authentic activities that emulate processes of scientific inquiry. However, research has not yet focused on investigating whether students perceive those activities as authentic and whether students'…

Today science teachers are expected to understand the nature of environmental education, and be competent in skills, methods, and procedures relevant to a science discipline. The purpose of this research was to explore pre-service science teachers' views with regard to environmental education, investigation conducted during a freshwater ecosystem…

The aim of this study is to investigate the effects of science, technology, mathematics, engineering (STEM) applications and STEM based teaching on 8th grade students' environmental attitudes, scientific creativity, problem solving skills and science achievement and to get students' opinions about STEM practices. Two groups were used in the…

To effectively employ inquiry-based learning to enhance students' inquiry practices and encourage them to think and act like scientists, science teachers must have a deeper understanding of the factors that influence scientific research and attitudes about scientist practice. This research contains the experience of two postdoctoral researchers in…

Active participation in project-based learning (PBL) could develop students` knowledge and crucial learning skills across various disciplines. However, the implementation of PBL in the K-12 classroom is usually impeded by the stepby-step PBL cycle. Micro project-based learning (MPBL), which advocates and adheres to the learning principles and…

This was second year's research in developing a biology learning module of ecosystem material that promotes mobile android-based local region potentials, after first year conducted a field examination on android e-module and limited testing in East Lombok Regency, West Nusa Tenggara and Sleman Regency, D.I. Yogyakarta. The second-year research…

The general aim of this action research was to offer ways of making science and technology education more effective and solving problems in the related field. The specific purpose was to determine how inquiry-based learning supported by instructional technologies improves students' achievement and develops their scientific inquiry skills. Taking…

The professional profiles of future scientists need to undergo a deep and rapid change to address recent advances in biomedical sciences and the social and environmental contexts in which we currently live. For instance, they have to be trained to be able to develop innovative and creative strategies for solving complex problems under a…

Chemistry self-efficacy (CSE) was identified as a critical affective construct to predict student success in chemistry classrooms. We surveyed students at the beginning and toward the end of a semester to measure students' CSE beliefs in introductory and general chemistry courses at a Hispanic-serving institution in the United States. First, the…
