Despite being a fundamental concept in biology, evolution continues to be one of the most challenging topics to teach in science education. Ideas of evolution emphasising anatomical or behavioural features of individuals, as opposed to the interplay between genetics and the environment, are reinforced through language and culture, making them…

During the COVID-19 pandemic, preexisting soil science laboratories were redesigned for self-guided learning (SGL). The SGL laboratories occurred on-campus during the fall 2020 semester in two introductory soil science courses at the University of Tennessee at Martin and Virginia Polytechnic Institute and State University. Students carried out the…

A straightforward protocol for the preparation of the colorful and air-stable diphenyl ditelluride is described. In one laboratory session, students isolate their product and characterize it via melting point determination, mass spectrometry, and NMR spectroscopy ([superscript 1]H, [superscript 13]C­{[superscript 1]H}, and [superscript…

Contextualized chemistry curricula have been shown to positively impact academic outcomes, especially in middle and secondary school levels. However, only a limited number of investigations on the impact of real-world contextualized curricula on students' learning outcomes in chemistry lecture courses in postsecondary education have been reported.…

The design and operation of an inverted cone, scalable vapor condenser, drawing cooling air from beyond the boundary layer and optionally working as a part of a gastight setup, are described and discussed. Besides its main use as a reflux condenser, it can also be used in one-plate distillations.

National reform documents all around the world issue an urgent need for the development of integrated STEM (Science, Technology, Engineering, and Mathematics) curricula. With the emphasis on the development of STEM curricula, there is also a need for improving teachers' and future teachers' conceptions of the integrated STEM approach. This study…

This paper introduces a scientific activity named "Pythagorean Cup of Justice" for teacher candidates to discuss values by integrating moral and ethical dimensions into science education, offering crucial insights into the cup's historical significance, enhancing fluid dynamics understanding, and engaging STEM-based activity. The study…

Racial biases, which harm marginalized and excluded communities, may be combatted by clarifying misconceptions about race during biology lessons. We developed a human genetics laboratory activity that challenges the misconception that race is biological (biological essentialism). We assessed the relationship between this activity and student…

The Joint Educational Project's (JEP) STEM Education Programs at the University of Southern California (USC) present an elementary-level curriculum centered on the science of stem cells in partnership with Dr. Adam MacLean, an Assistant Professor of Quantitative and Computational Biology at USC for the broader impacts of a National Science…

Existing research primarily examines the impact of structured, credit-bearing service learning in undergraduate chemistry, leaving the potential contributions of co-curricular service learning and its lasting influence on chemistry graduates underexplored. Therefore, this mixed-methods study aimed to assess the lasting impact of co-curricular…

This study explored the impact of interactive e-books on the viewing behaviors of children in science demonstrations at museums. To conduct this study, an interactive e-book on a pendulum experiment was developed and integrated into a physical science demonstration at a museum. Two scientific demonstrations were conducted in this study. The first…

The scientific community continues to give conflicting impressions about the contribution of laboratory activities to science learning and yet ignores the views of students who are the focus of learning. In this paper, we reviewed postsecondary school students' experiences in the science laboratories. Students were most concerned about the impact…

We provide an update on the "electrochemistry designette" in relation to its pedagogical effectiveness to students and experiential learning. We have previously proposed that the designette be applied as an assessment tool to measure the students' competence on electrochemical principles through a series of objective metrics. Based on…

In science education, there is a now established focus on fostering students' meaning making through/as multimodal representations as part of their induction into the epistemic practices of the discipline. Increasingly, this agenda is aligned with an emphasis on nurturing students' creative reasoning, as researchers move to enrich theories of…

We present two simple classroom exercises designed to explain challenging concepts in conformation for students beginning organic chemistry. These macroscopic demonstrations serve as analogies to bridge students' understanding of flat two-dimensional drawings to real three-dimensional molecules. In the first demonstration, an apple is drawn from…
