Assessing students' participation in science practices presents several challenges, especially when aiming to differentiate meaningful (vs. rote) forms of participation. In this study, we sought to use machine learning (ML) for a novel purpose in science assessment: developing a construct map for students' "consideration of generality,"…

Learning to create, use, and evaluate models is a central element of becoming a scientist. In physics, we often begin an analysis of a complicated system with highly simplified or toy models. In introductory physics classes, we tend to use them without comment or motivation. Some students infer that physics is irrelevant to their understanding of…

In this study, it is aimed to calibrate an LDR-Lux meter with a calibration setup which includes a light bulb whose brightness can be changed by using a dimmer circuit, a data acquisition card, a smartphone and a lux meter application. In order to make the measurements more accurate and to prevent errors in the measurements, a smartphone and a…

We developed new teaching materials, electrical resistors and capacitors, using carbon nanotube (CNT) paper and carbon fibre (CF) paper to foster students' creative thinking, thereby deepening and extending learning. Using a CNT-paper electrical resistor, it is possible to elucidate the dependence of the resistance value on the length and width.…

Peer learning programs have been developed to support many introductory science courses by providing additional instruction and engagement. These programs are beneficial to both learners and instructors, providing content learning and confidence and attitudinal gains. There is evidence that the benefits of peer learning are higher when students…

In science learning, the experiment is an essential activity to facilitate students to discover and develop knowledge as well as to enhance scientific process skills and self-confidence. This study aims to create a simple experimental apparatus related to the principle of fluid continuity that can be made and conducted by the teacher and student…

The importance of using dialogue as a pedagogical tool to enhance student learning in science has been widely recognised in research literature. Effective classroom dialogue is dependent upon teaching which successfully engages students in critical thinking and deep learning, requiring many teachers to think and work differently in science…

On 12 Mar. 2020 Dickinson State University moved all classes to distance delivery (DD) in response to COVID-19. Faculty had only a brief opportunity to plan, as the turn-around to DD was very rapid. Meaningful laboratory exercises were needed for SOIL 210--Introduction to Soil Science. The senior author learned about the Science of Agriculture…

This study investigated the introduction of the second law of thermodynamics using the Legitimation Code Theory (LCT) (semantic waves) among first year chemistry students. The aim of the study was to investigate the extent LTC (semantic waves) reduce the entropy concept's complexity and abstractness when introducing the second law of…

Technology-enhanced collaborative inquiry learning has gained a firm position in curricula across disciplines and educational settings and has become particularly pervasive in science classrooms. However, understanding of the teacher's role in this context is limited. This study addresses the real-time shifts in focus and distribution of teachers'…

Most of the research on student understanding of evolution by natural selection has focused on undergraduate biology courses for science majors. However, the majority of undergraduates in the United States will not enroll in a biology course for majors. In this study, we identify the extent of natural selection understanding that students acquire…

Digital badges are credentials earned via a digital presentation to demonstrate the mastery of a technique. They have been utilized in General Chemistry laboratory courses as an assessment tool and to document students' development of a skill. A digital badge assignment was developed for thin layer chromatography (TLC) and integrated into a…

In 2014, evolution through natural selection was introduced to the primary science National Curriculum in England for year 6 (ages 10-11). As teachers had little prior experience of teaching this concept, it provided a rare opportunity to study the effectiveness of different approaches. A study was developed to investigate the impact of…

This undergraduate dissertation project was designed to enhance organic and analytical chemistry skills of final year forensic science students. A modified Birch reaction method was employed to synthesize amphetamine from ephedrine and detect the most known byproduct of clandestine manufacture of amphetamines, e.g.,…

The COVID-19 pandemic has swiftly forced a change in learning strategies across educational institutions, from extensively relying on in-person activities toward online teaching. It is particularly difficult to adapt courses that depend on physical equipment to be now carried out remotely. This is the case for bioinformatics, which typically…
