Many physics learners take the specific mathematical representations they are using as part of their learning and doing physics for granted. The paper addresses this problem by highlighting two goals. The first is to show how a historical investigation from history of science can be transformed into a concrete lesson plan in physics, in a physics…

There is a growing body of research that suggests better course outcomes for instructors that incorporate active learning into their curriculum. Laboratory exercises can be used to promote active learning. The objective of this study was to develop and assess the efficacy of a gluten-free bread laboratory exercise for an undergraduate course…

We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…

Bacteria, viruses, and other invisible creatures are, in brief, microorganisms. Especially with the onset of the COVID-19 pandemic, the features of microorganisms, their density, and relevant precautions have grown in importance. Knowing the density of microorganisms at school will cause our cleaning habits to change. In this study, efforts were…

A laboratory project to introduce upper-level undergraduates to Pd-catalyzed C-N [sigma]-bond forming reactions is described. The exercise involves evaluation of monodentate phosphine ligands and solvents for the Buchwald-Hartwig coupling of 4-chloro-or 4-bromo-anisole with morpholine. Students gain experience in the synthesis of a biarylphosphine…

In this laboratory experiment, students explore the aquatic photochemical fate of ranitidine and cimetidine, two common pharmaceutical pollutants found in wastewater. It provides an engaging environmental context for students to develop knowledge of reaction kinetics and photochemistry as well as skill in using analytical instrumentation. This…

Water is a meaningful context for children to engage in inquiry, and to acquire and use science and engineering practices, such as developing spatial thinking and early concepts of water dynamics. This book shows teachers how to provide children with opportunities to engineer water movement through pouring and filling containers of various kinds…

The aim of this research was to assess students' ability to explain scientific phenomena by means of a POE pedagogical tool. To achieve this aim, we conducted home experiments in a digital environment. In this qualitative and transversal ex-post-facto research, 775 pupils (aged 13-18 years) enrolled in compulsory secondary education from the…

Research Findings: This study explores how Chinese preschool teachers' enactment of Concept Development (CD) strategies, as measured by the Classroom Assessment Scoring System (CLASS), might effectively elicit children's higher-order thinking during whole-group science teaching. Participants included 25 Chinese preschool teachers and 800 young…

This integrated STEM activity on the design of a vertical farming system has biology as the lead discipline and relates to the concept of photosynthesis. Students investigated the optimal design of vertical farms that will deliver appropriate amounts of water, sunlight and carbon dioxide to plants such that there will be optimal yield. Through…

This study aims to examine the moderating effect of participation in informal science activities on the associations among students' awareness of environmental issues and their attitudes toward science and epistemological beliefs. The data set included 9841 15-year-old students from four Chinese provinces (Beijing, Shanghai, Jiangsu, and…

This study aims to investigate the impact of laboratory activities prepared based on STEM-based learning on the competence perceptions in 21st-century skills (learning and innovation skills, life and career, information, media, and technology skills) and STEM awareness. The sample group consisted of 53 pre-service science teachers studying in year…

Measuring the factors affecting the implementation process are critical steps for understanding how, why, and under what circumstances integrated STEM curriculum innovations work. The overarching goal of this National Science Foundation (NSF) funded project was to design, field-test, implement, and evaluate contextualized integrated STEM learning…

Student engagement in math and science courses decreases starting in middle school and continues throughout high school (Museus, et al., 2011). This lack of engagement results in students taking only the required math and science coursework and not advanced coursework that would help prepare them for future careers in science, technology,…

The main purpose of this study is to determine what teachers and academicians think about the process of designing and implementing science activities in informal settings and make suggestions as to how to teach more effectively in them. This study is a cross-sectional survey study and divided the teachers constituting the sample group into…
