A simple experiment was developed to introduce students to the sustainable procurement of water through fog harvesting that can be used for drinking or irrigation purposes. Access to clean water and sanitation is problematic particularly within dry regions such as in areas of Peru, although there is a significant amount of fog in the mountainous…

This project engaged Ghanaian secondary pupils in authentic science and engineering activities by using model biodigesters that reduce organic waste and produce biogas and fertiliser. The pupils' activities paralleled scientists' activities, such as asking research questions and designing experiments. Our study included two cohorts of Ghanaian…

In Vietnamese secondary education, traditional science teaching that focuses on theory over practical application presents a challenge to developing students' scientific competence, a key priority of the national curriculum. Scientific competence is broadly defined as the ability to explain phenomena, conduct investigations, and apply knowledge in…

Small-group activities play a crucial role in biology education, fostering active learning, teamwork, and critical thinking. While their benefits are well-documented, there is a need for innovative classroom exercises that provide students with a real-world perspective on biotechnology and pharmaceutical industries. This paper introduces a…

Moments of inertia (MOIs) are usually derived via substantial integration and may intimidate undergraduates without prior backgrounds in calculus. This paper presents an intuitive geometric operation, termed "squashing," that transforms an object into an equivalent one with a reduced dimension, whose MOI is simpler to determine. The…

Background and purpose: Most studies have agreed on the benefits of students' participation in discussing socio-scientific issues (SSIs), but few have focused on the serial behaviors through which students declare their positions. Design and method: This study analyzed the serial behaviors of university students when participating in the…

Electronic student worksheets (e-worksheet) are needed as alternative teaching materials in learning. This study aims to produce teaching materials in the form of e-worksheet based on Search Solve Create and Share (SSCS) Islamic context to improve science process skills on class XI excretory system material that is worthy of the results of…

As part of its STEM programming initiatives, Community Boating, Inc., the nation's oldest public sailing organization introduced an "Introduction to Microscopy" course merging principles of scientific investigation with analytical techniques using compound light microscopes. Boston's Charles River provided the environmental setting for…

With the rapidly increasing demand for STEM skills, many scientists, mathematicians, engineers, and technology professionals encourage students to pursue STEM careers. However, communicating science to lay audiences is challenging due to complex scientific terminology. This qualitative research aimed to demonstrate how an exemplary scientist, Dr.…

The COVID-19 pandemic demonstrates how understanding science in context is not a luxury but a necessity in our times. In order to make sense of a complex issue such as a pandemic, pupils need to understand not only how scientists do science but also how science relates to other school subjects. By drawing on findings from funded research projects…

This article describes a straightforward approach to deliver an enzyme assay and kinetics laboratory via online delivery methods in the time of COVID-19.

The purpose of this study was to examine "pre-service science teachers'" (PSTs) development of multiple levels of representation and written arguments using an immersive approach to argument, the "science writing heuristic," in general chemistry laboratory I and II courses. Fifty PSTs participated the study, 20 experiments were…

Laboratory classes are a central element of all biochemistry and molecular biology programs. These play a role in developing students' hands-on and technical skills and also offer much more. The design of laboratory classes depends on many factors including the programs the students are enrolled in, the level they are at, employment destinations,…

The aim of this study was to investigate the effectiveness of scenario-based multiple-choice questions to assess students' science process skills. To achieve this objective, a test with 32 scenario-based multiple-choice questions evaluating students' skills in formulating hypotheses and identifying variables was prepared and administered to 370…

Assessment instruments that generate quantitative data on attributes (cognitive, affective, behavioral, "etc.") of participants are commonly used in the chemistry education community to draw conclusions in research studies or inform practice. Recently, articles and editorials have stressed the importance of providing evidence for the…
