Medicinal chemistry is an integrated discipline that primarily concerns the design, discovery, synthesis, identification, and interpretation of biologically active compounds at the molecular level. To assist undergraduates in understanding the core subjects of medicinal chemistry, we introduced a closed-loop education mode combining fundamentals…

High-performance liquid chromatography (HPLC) experiments are an important part of the undergraduate analytical instrumentation laboratory courses and usually use commercial C18 silica-packed reversed-phase columns. In this experiment, a simple method of preparing SiO[subscript 2] core-shell packed columns was developed to enable students to…

High school students and students in the first years of college have difficulties in understanding the topic of stoichiometry and, in particular, the concept of limiting reactant. Proposals aimed at overcoming these learning obstacles tend to focus on analogies, and there are few sequences that approach teaching from an experimental perspective.…

Why should our life science colleagues adopt, adapt, and implement fractal thinking into their research and teaching paradigms? While numerous articles and books have been written about the utility, power, and insight that can be gained by using fractal analysis of data and developing fractal models, other than just appreciating the beauty of…

The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

No scientific concept in the twenty-first century has garnered more attention from scholars outside the scientific community than the Anthropocene. Despite the official rejection by the geological community in March 2024 of the proposal for an Anthropocene Epoch as a formal unit of the Geological Time Scale, it is expected to remain an invaluable…

Background: Collaborative learning offers benefits, but its potential is often undermined by motivational challenges. This study uses the situated expectancy-value theory to explore how students' expectancies for success relate to group-level regulation of learning during collaborative interactions. The study considers success expectancies both as…

The ability to extract structural information from a drawing of a molecule is key to being successful in organic chemistry. One source of difficulty for novices in interpreting structures is that hydrogens bound to carbon are represented implicitly in the often-used line-angle structures. Other representations that explicitly show hydrogens, such…

STEAM (Science, Technology, Engineering, Arts, Mathematics) learning is designed to contextualize the abstract concepts of science in chemistry learning. Integration STEAM in chemistry learning needs a learning model to help students understand real-world problems. For this reason, STEAM-PBL (Project Based Learning) was employed. This paper…

This study aims to uncover the prompts most frequently repeated by pre-service teachers when using the Copilot technique, as well as their reflections on its use in preparing and planning science lessons for fourth graders. The qualitative research methodology with an exploratory case-study design was conducted on a purposeful sample of 20…

This study employed a qualitative interpretative case study methodology, involving two teachers and one class of learners from two selected schools. The researcher used observation to address a critical question: How does the application of the Tshivenda scientific language register shape meaningful learning? The findings reveal that the…

Understanding the photosynthesis concepts is challenging due to its abstract nature, often leading to student misconceptions. This study aims to identify and analyze misconceptions among science and social studies students using the image analysis method. A total of 78 students (32 science, 46 social studies) participated, selected through a…

This study analyses the effectiveness of directed vs. minimally directed inquiry-based instructional approaches in improving students' attitudes toward physics. It specifically compares the impacts of cognitively guided instructional strategy (CGIS) and Cubing instructional strategy (CIS) on student attitudes. Using a pretest--post-test…

Recently, our course team transformed a large-enrollment introductory genetics course from being predominantly lecture based to active learning based. During class sessions, students engaged in problem solving, which occurs when a student attempts to solve a problem without knowing the path to complete it. We designed class activities…

Inquiry-based science instruction fosters critical thinking, problem-solving, and scientific literacy by engaging students in exploration, questioning, and reflective learning. However, implementing inquiry-based practices presents significant challenges for elementary teachers, who often balance multiple subjects and may feel less confident…
