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…

Wave optics is a mandatory part of Croatian secondary school physics curriculum for students in the final year of secondary school (age 18-19). Many physics education research studies have shown that it is a difficult physics topic for both university and secondary school students. An inquiry-based teaching sequence on wave optics, designed for…

The laboratory plays a crucial role in science education. However, teacher education for pre-service teachers' design performance in the laboratory is still challenging. This study paved the way for redesigning traditional laboratory teaching into a student-centered approach: inquiry-based design thinking (IBDT). To investigate the impact of the…

The blended synchronous classroom fosters equitable and balanced educational development; however, challenges persist, including low motivation and suboptimal effects on the deep learning of remote students. This study employs a student-centered learning approach and incorporates the process-oriented guided inquiry learning (POGIL) strategy into…

Metabolism is always a challenging topic in biochemistry. In our project, a courseware called "Metabolism Metro" was developed. "Metabolism Metro" is a self-learning tool which aims to facilitate students learning of metabolic pathways in an interactive and easy-to-understand manner. The courseware includes both pre-class and…

We designed and evaluated a student laboratory workshop on plant-based vaccines against the SARS-CoV-2 virus. The workshop focused on hands-on laboratory techniques, including DNA extraction from rice seeds, where the recombinant protein was produced, detection of the transgene, and basic concepts on how vaccines work in the human body to offer…

Artificial intelligence (AI) technologies continue to revolutionize various sectors, including their incorporation into education, particularly in K-12 science education, which has become evidently significant. This paper presents a bibliometric analysis and systematic review that examines the incorporation of AI technologies in K-12 science…

In an effort to further develop critical thinking and problem solving skills, a guided-inquiry-based, multioutcome organic chemistry synthesis and characterization experiment was developed. Students were provided with the protocol for a time-saving microwave-assisted acetanilide synthesis reaction from acetic anhydride and an unknown primary aryl…

This study examined the impact of a project-based learning module on young children's scientific practices in urban and Indigenous areas. The module was developed by drawing upon early science standards and research on scientific practices and project-based teaching approaches. Ninety-eight children from northern Taiwan participated. Their average…

This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

The use of digital technologies as teaching and learning materials supports and enhances science learning, encouraging students to develop valuable inquiry skills and knowledge. In response, this paper seeks to explore digital inquiry-based learning as a useful aid for teaching the elementary school science curriculum on plants in Malaysia. There…

Background: Scientific thinking is an essential learning goal of science education and it can be fostered by inquiry learning. One important prerequisite for scientific thinking is procedural understanding. Procedural understanding is the knowledge about specific steps in scientific inquiry (e.g. formulating hypotheses, measuring dependent and…

This study was an action research self-study that examined my role as a teacher educator supporting a resident teacher in learning how to design inquiry-based culturally responsive science lessons. I explored my own growth in understanding how to act as a teacher educator to provide appropriately scaffolded support to promote learning for a…

Teachers lack effective curriculum-based instruments to assess their students' scientific competence that would provide information for modifying their inquiry instruction. The main purpose of this study was to develop and validate a Curriculum-Based Scientific Competence (CBSC) test to assess students' scientific competence in a 1-semester Grade…

Intrinsic motivation plays a unique mediating role in student academic performance. An inquiry-based learning (IBL) physics practical is studied in terms of effects on secondary school students' intrinsic motivation towards performing science practicals. After performing IBL experiments on ionizing radiation, 38 secondary school physics students…
