The purpose of this study is to explore the relationship between life sciences teachers' understanding of indigenous knowledge (IK) and their views of integrating Indigenous Knowledge in their teaching practice. A qualitative case study research approach was adopted, and purposive sampling strategy was used to select eight Grades 10-12 life…

The present study has aimed to develop and validate a protein concept inventory (PCI) consisting of 25 multiple-choice (MC) questions to assess students' understanding of protein, which is a fundamental concept across different biology disciplines. The development process of the PCI involved a literature review to identify protein-related content,…

This study aims to develop, implement, and evaluate an instructional design model to enhance the pedagogical content knowledge (PCK) of physics student teachers. Model development is accomplished in five stages over two years: 1) problem identification, 2) preliminary identification of the product and design concepts, 3) preliminary theories and…

Protein translation is a fundamental biological process taught in introductory general biology classes at the undergraduate level. This core scientific topic is often hard for students to understand as it involves several key players and piecing together of information learned in multiple lectures. The current study examines the effectiveness of…

The goal of the study is to create Visual Basic and MATHCAD apps to create programs that show the core force using physical forces as an example. The research subjects are high school teachers and students; the inherent context is high school STEM courses. Programs for computer visualization have been developed, and theoretical investigations have…

The teaching of conceptual understanding is a key objective in the field of science education. But students, on average, do not adequately understand the concepts in a large number of science subjects. This is the case with Ethiopia's students as well. Additionally, conventional instruction is the primary method used by Ethiopian school teachers.…

Concept-heavy courses such as Biochemistry in life and physical science curricula are challenging for many college-aged students. It is easy for students to disengage in a lecture and not learn the subject matter while in class. To improve student learning and participation, we employed a flipped format for the first half of the course and…

The study aimed to assess the effectiveness of the Predict-Explain-Enact-Observe-Reflect (PEEOR) instructional strategy on general science students' conceptual understanding and motivation in the topic of motion and force. The research employed a pre-test post-test quasi-experimental design. The sample consisted of 107 general science summer, year…

Informal science activities occurring at various non-traditional learning sites present a pivotal model for involving youths in the science learning process. The dynamic landscape of emerging technologies has prompted the exploration of innovative methodologies to bolster and refine informal science education. However, the expanse of this field…

This study utilized the SEC (Survey of Enacted Curriculum) method to examine the alignment between Chinese high school chemistry curriculum standards (HSCCS) and the assessment of 'Chemical Reaction Principles' in the National College Entrance Examinations (NCEEs). The HSCCS and NCEEs were coded into two-dimensional matrices separately using SPSS,…

Although integrating the history of science (HOS) into teaching has long been recommended in science education research, studies have revealed conflicting results on its effectiveness. These are mainly due to the need for more studies in this context. Therefore, this research aimed to explore the impact of HOS teaching on science process skills,…

A balanced interrelation between theory and practice is still often missing out in many (language) teacher education programs (Esteve, 2018; Lantolf & Esteve, 2019). Hence the need to critically analyze teacher educators' professional practice and rethink it. This paper presents a deep reflection upon the difficulties and the possibilities of…

This paper consists of a systematic review of the literature on ChatGPT's application in science education, drawing from studies conducted between January and September 2023, examining the current landscape, challenges, and implications of integrating ChatGPT into science classrooms. Analysis revealed a predominant emphasis on physics and…

Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…
