Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

A comprehensive teaching experiment plan tailored forthird-yearundergraduates has been developed. Initially, instructors synthesize(E)-2-(4-((4-(2-hydroxyethoxy)-3-methylphenyl)­diazenyl)­phenoxy)-ethan-1-ol­(M-Azo-2)monomer as part of the preclass preparation. Subsequently, studentsperform an acylation reaction experiment to prepare an…

This paper investigated the effect of outdoor teaching activities on secondary school students' acquisition of science process skills in science. Two research questions and two null hypotheses guided this study. This study adopted a single-group pre-test post-test quasi-experimental design. This study was conducted in the Mangalore North cluster…

Most students enter college without any exposure to polymer science, which leads to the poor understanding and slow implementation of plastic recycling programs in the United States. To address the knowledge gap in chemical recycling, we introduce a 2-part laboratory experiment that was conducted in multiple high schools and public outreach events…

The galvanic cell is a typical interdisciplinary topic, which is primarily taught in chemistry but its underpinning is closely related to physics. Student learning in galvanic cell has been extensively studied in chemistry education, which has revealed a large number of misconceptions that are difficult to change through traditional instruction. A…

Physiology concepts, such as acid-base balance, may be difficult for students to understand. Systems modeling, a cognitive tool, allows students to visualize their mental model of the problem space to enhance learning and retention. We performed a within-subjects three-period randomized control comparison of systems modeling versus written…

This mixed-methods research study aimed to observe the changes in relational conceptual changes and achievement in photosynthesis and cellular respiration in 15 seventh-grade students using the variation theory of learning, a framework for contextual distinctions, and supports the Common Knowledge Construction Model (CKCM) for science education.…

We investigate learning difficulties among second-year students in electromagnetism courses when they apply Ampère-Maxwell's law. Using phenomenography, we analyzed written answers from 65 undergraduate physics students to four questions on Ampère's and Ampère-Maxwell's laws. We complemented our research by interviewing 12 students. To design the…

We present two studies to investigate the extent to which attending a planetarium presentation increases secondary school students' understanding of the apparent motion of the Sun and stars. In the first study, we used the Apparent Motion of Sun and Stars (AMoSS) test in a pretest/post-test/retention test setting to measure learning gains and…

Resonance is a crucial concept in Organic Chemistry that enables both deriving chemical properties from molecular structures and predicting reactions by considering electron density distribution. Despite its importance for problem-solving and learning success, learners encounter various difficulties with this concept. Although prior research…

This study presents a practical developed for an undergraduate geotechnical engineering course. The practical was designed to reduce systematic issues so that students could focus on cognitive and conceptual issues rather than practical minutiae. Compression tests were carried out on dry halite, enabling consistent specimen densities to be…

Do children think of genetic inheritance as deterministic or probabilistic? In two novel tasks, children viewed the eye colors of animal parents and judged and selected possible phenotypes of offspring. Across three studies (N = 353, 162 girls, 172 boys, 2 non-binary; 17 did not report gender) with predominantly White U.S. participants collected…

This study aims to determine those topics and concepts that biology and science teacher candidates find most challenging to learn in biology lessons. A qualitative case study research method was used to this end. A total of 132 science and biology teacher candidates studying at a state university were asked to write down the ten subjects or…

Single-molecule localization microscopy (SMLM) has revolutionized our ability to visualize cellular structures, offering unprecedented detail. However, the intricate biophysical principles that underlie SMLM can be daunting for newcomers, particularly undergraduate and graduate students. To address this challenge, we introduce the fundamental…

Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…
