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…

The purpose of this study was to explore instructional designs for promoting inquiry practices in secondary school textbooks. Three criteria were employed to select the textbooks: (1) approved by the Ministry of Education in Singapore and the Ministry of Education and Culture in Indonesia, (2) used in secondary schools, and (3) included content…

The activity proposed in this study aims to investigate the equilibrium between the liquid and vapor phases in a mixture of water and acetic acid, both of which are volatile substances. High school students can easily determine the composition of the liquid phase and its corresponding vapor phase at equilibrium using a simple and conceptually…

Models that illustrate renal fluid dynamics are scarce within the secondary and postsecondary landscape. This work summarizes the efforts to build a rudimentary model renal corpuscle (MRC) that can be employed in a problem-based learning exercise or demonstration to teach basic principles of renal physiology to secondary students or…

Recent solar eclipses provide relevant real-world contexts for learning about the scientific phenomena of the lunar phases. News coverage of the phenomenon may have raised questions such as, "Why does the Moon look different at different times, and sometimes as if it is not there?," and "What patterns can be found in the lunar…

The aim of this research was to provide preschool children with context-based science and nature activities and basic process skills. The research was carried out with 11 children aged 48-60 months in the second term of the 2019-2020 academic years. The research was designed according to action research, one of the qualitative research designs. In…

Climate change caused predominately by carbon dioxide (CO2) from fossil fuel use is a critical issue for our future. It is incumbent on science educators to learn about it and teach it in ways that illustrate the power of science to understand climatic changes and model past, present, and possible climate futures. It is equally important for…

This study used a case study, one of the qualitative research methods, with the aim of developing guidance materials based on the argumentation-based science learning (ABSL) approach for concepts in the 6th grade unit "Sound and Its Properties" and to examine students' argumentation levels and conceptual understanding. The activity…

This study analyzed Bahraini primary school science textbooks and workbooks from grades 1 to 6 in terms of their coverage of the five essential features of scientific inquiry. These features include the following: feature 1, engaging learners in scientifically oriented questions; feature 2, making learners give priority to evidence in responding…

New approaches to microbiology education are needed to ensure equitable representation in microbiology and to build literacy in microbiology and science broadly. To address this goal, we developed a course held at the collegiate level that uniquely integrated microbiology, Indigenous studies, science and technology studies, and arts and…

This study explored the views of 63 Taiwanese pre-service teachers who had participated in a workshop about the value of integrating drama-based approaches in their practical science learning. It was primarily designed to investigate the pedagogical approach of Heathcote and other founders of process drama. In addition, it examined specific claims…

In this in-class activity, organic chemistry undergraduates try to place an assortment of molecules in chronological order from oldest to most recently synthesized. In the students' first attempt, they use their knowledge of reactions and synthesis to analyze the organic compounds for their structural complexity. Before a second attempt, the names…

Design activities are gaining interest as rich contexts for learning science, technology, engineering, and mathematics (STEM) subjects. STEM teachers may find this challenging however, as designing requires support that they are not used to providing. In a subject like chemistry, teachers would have to balance creativity and responsibility for the…

Taking on an agentic perspective, this study employed a digital ethnographic approach to examine a science teacher's emotional experiences in an online graduate science education course during the COVID-19 pandemic. Veronika, the teacher, revealed her feelings of grievance and loss to the graduate course cohort at the advent of large-scale school…

Escape rooms are making their way into the chemistry classroom as a learning tool. However, escape rooms require a large amount of preparation and setup, and they are only novel and exciting for a single play-through. For escape room games to be incorporated into multiple class periods, they must be streamlined for reuse. In this work, I introduce…
