Graduate teaching assistants (GTAs) are key partners in the education of undergraduates. Given the potentially large impact GTAs can have on undergraduate student learning, it is important to provide them with appropriate preparation for teaching. But GTAs are students themselves, and not all of them desire to pursue an academic career. Fully…

The COVID-19 pandemic presented several challenges to both teachers and students. The rapid shift to an online learning environment demanded the development of effective teaching strategies to support student learning. This work describes teaching strategies developed to teach physics during the COVID-19 period. The strategies included posting…

Pregraduate students often have low success expectations toward their thermodynamics courses, which are often considered too abstract and remarkably difficult to understand. For this reason, they may not even try to reach any level of comprehension while settling for reproducing mathematical calculations and memorizing definitions to pass the…

The Ball Bearing High Voltage generator is a fairly simple and transparent apparatus that can serve as a tool to motivate conceptual descriptions and calculations in electrostatics that are normally presented to our students in a rather dry and matter-of-fact fashion. For example, instead of posing a problem in the typical textbook form of…

This brief review provides insights into the recent advances made by the Unity game engine into education and the ways that learning resources can be used to teach novice bioscience students to use the VR/AR affordances of the platform. We present our own practises for implementation of a novel gamification task for final-year bioscience students…

The present study analyses the impact of negotiation processes on activating argumentative resources for decision-making in a socioscientific issue (SSI) in biology classes. The research focuses on the potential of group-based negotiation processes to activate the use of relevant argumentative resources without any prescribed or explicit…

In quantum mechanics courses, students are often asked to solve bound and scattering state problems. The use of an ordinary differential equation is a standard technique to solve these questions. Here, we investigated students' problem-solving processes for two typical problems of a single particle in one spatial dimension: a bound state problem…

This study presents an experimental method that illustrates and quantifies the Doppler-effect phenomenon. Two stages of the experimental process were carried out. First, a simplified ripple tank was used to depict the Doppler effect, and the whole experiment was recorded by a digital camera. Second, video analyses of the recorded experiment were…

There are three aspects of science: (1) scientific knowledge: what we know about the natural world, which would include crosscutting concepts; (2) scientific practices: skills and knowledge necessary for building scientific knowledge; and (3) nature of science (NOS): how science works (Bell et al. 2003). Most science instruction emphasizes the…

In times of the explosion of distance learning, because of emergency due to the pandemic, smartphone sensors and cameras are extremely valuable for teachers as they allow students to perform significant experimental activities in their own homes. The open-source software Tracker can be used in combination with the smartphone camera to perform…

The drag effect on a falling ball caused by air is a conventional subject in the most well-known textbooks of classical mechanics and fluid dynamics. Further, there are some papers that employ video analysis to track objects movements in the air making it possible to obtain position data as a function of time and its graphs. However, none of them…

The aim of this study is to examine prospective science teachers' (PSTs) mental models and meanings for the concept of chemical reaction. For this purpose, this study adopted a phenomenological research design including 48 PSTs. To determine the mental modeling about chemical reactions, PSTs were given an interview card showing the reaction…

The aim of this study was investigated of prospective science teachers' understandings on ergastic substances with the semantic mappings. This study was phenomenological research method. 38 prospective science teachers in the science teaching department of a public university participated in the research. The prospective science teachers were…

The law of conservation of momentum can be applied to a wide range of processes whether it is the collision of subatomic particles, rocket propulsion, or the recoil of a cannon. In this experiment two technologies, the Arduino microcontroller and a PASCO smart cart, are used to create a movable rubber band launcher. The Arduino microcontroller is…

In this guided-inquiry lesson, students were tasked with determining the efficacy of an at-home drinking water filter at removing lead (Pb) from tap water using graphite furnace atomic absorption spectroscopy by determining the concentration of lead before and after filtration. The lesson was structured to allow students to choose and perform…
