The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

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…

Ludic-didactic material has systematically been proven to be a useful tool that enhances teaching and learning processes, at practically any educational level by reducing the stress level of students and creating a feeling of team spirit and trust. In chemistry courses, significant efforts have been made to improve the learning of intermolecular…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

It has been shown that many people do not understand how scientific knowledge is built and accepted, even after scientific education. One way to deal with this problem is through teaching about the Nature of Science (NOS). NOS can be understood as a pedagogical construct aiming to foster the understanding of the main characteristics of scientific…

Model-based inquiry (MBI) is an instructional framework designed around the construction, revision, and testing of models by students to make sense of and explain a phenomenon (Windschitl et al. 2008). Focusing on explaining natural phenomena provides a specific context for students to learn and apply scientific understandings to and can help…

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…

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'…

A new perspective on chemistry learning could be the optimal learning moment of view based on flow theory. Optimal learning moments (OLMs) that occur when students experience high levels of interest, challenge, and skill at the same time were investigated in this study. Participants of the study were 47 pre-service science teachers. Data were…

This study examined the impact of a practice-based approach to in-service science teacher education, using small-group discussions about photovoltaic (PV) science to support teachers' instruction on sustainable energy transitions in response to climate change risks. Ultimately, we aimed to promote teachers' PV science comprehension as well as…

This study investigates the perspectives of physical sciences teachers regarding implementing learning style-based instructional strategies [LSBIS] in science classrooms in South Africa. The aim is to identify the challenges and opportunities associated with integrating these strategies into teaching practices. Research on learning styles and…

This study investigated meaning-making of arrows in a representation of the greenhouse effect among 14-year-old secondary school students. Data was generated during Biology lessons where 74 students discussed how they interpreted a representation from the Swedish Society for Nature Conservation, which is an NGO that produce school material. The…

Students with religious beliefs often find it difficult to accept the theory of evolution. It is important that educators feel comfortable addressing student questions on the compatibility of evolution and religion. We designed an online professional development course that taught the foundational principles of both evolution and religion in order…

Web-based discussion tools have emerged as valuable platforms in teaching and learning chemistry. Despite the increasing use of web-based discussion tools, their effectiveness in enhancing cognitive, social, and teaching aspects of organic chemistry remains underexplored. Therefore, this review aims to address the gap by synthesizing relevant…

With teachers continuing to report challenges in classroom management and difficulties in implementing scientific inquiry, the current manner in which science practical work is conducted in schools suggests the need for added teacher support. In this regard, we can leverage computer vision to provide instructional support by relieving teachers of…
