We report a research-based proposal on electromagnetic induction within the theoretical framework of the Model of Educational Reconstruction. The proposal is based on a sequence of inquiry-based experimental activities centered on hands-on materials and "Real-Time" quantitative experiments, through which students explore the…

Physics education research is replete with observations and proposed explanations for gender disparities in physics. In this work, we operationalize a definition for equity as everyone has access to the learning environment and everyone's voice is heard (adapted from previous definitions). We review prior research that observed inequities in…

Using smartphones in experimental physics teaching offers many advantages in terms of engagement, pedagogy and flexibility. But it presents drawbacks such as possibly endangering the device and also facing the heterogeneity of available sensors on different smartphones. We present a low-cost alternative that preserves the advantages of…

The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work-energy theorem.…

The capstone course for many Earth Science programs is a field course. To increase accessibility and to create a substitute in light of the cancellation of in-person courses due to the COVID-19 pandemic, we developed an online introductory field geology course. The course consisted of six different modules. The first was a virtual reality room,…

This paper describes the development of a fully remote upper-class biochemistry lab course. The sudden change to online teaching in the middle of spring semester 2020 had a primarily negative impact on laboratory teaching. These effects were mitigated because the students had done many of the basic hands-on procedures before the switch. A true…

This study measures the effect of productive failure instruction in a digital inquiry environment on developing deep understanding and achievement of organic chemistry among Saudi Arabian secondary school students. The study adopted the experimental design of control and experimental groups with pre- and post-measurements. The sample comprised 66…

The American Chemical Society holds supporting diverse student populations engaging in chemistry as a core value. We analyzed chemical concept inventory scores from 4,612 students across 12 institutions to determine what inequities in content knowledge existed before and after introductory college chemistry courses. We interpreted our findings…

Drawing from intersectional feminist scholarship, we communicate how Salina and Marelis, both women of color, teach science for social justice in the face of significant institutional challenges. Theorizing from their experiences and practices, we articulate a feminist praxis for school science, which includes (1) building community and…

The present work is the report of an intern, who through the theme: "Drugs" shows the importance of the use of didactic sequence in the teaching of chemistry for the construction of concepts. The content was applied in classes of the 3rd year of high school, in a public school, in the city of Apucarana - PR. In this sense, the main types…

Written scientific argumentation is a common practice among scientists, yet it is relatively absent from science K-12 classrooms (Applebee & Langer, 2013). However, recent research shows that opportunities to engage in collaborative discourse and argumentation provide students enhanced conceptual understanding and reasoning. Since one of the…

Games are fully accepted by students, as they stimulate memory, activate reasoning capacities in brain, improve the knowledge and keep out the stress. Our innovation teaching group is interested in using games for teaching Biochemistry of the Chemistry degree. Most of the individual games found in Internet are classified in numerical games…

Interactive simulations allow students to discover the underlying principles of a scientific phenomenon through their own exploration. Unfortunately, students often struggle to learn effectively in these environments. Classifying students' interaction data in the simulations based on their expected performance has the potential to enable adaptive…

In collaborative problem solving (CPS), people's actions are interactive, interdependent, and temporal. However, it is unclear how actions temporally relate to each other and what are the temporal similarities and differences between successful vs. unsuccessful CPS processes. As such, we apply a temporal analysis approach, Multilevel Vector…

Integration of content areas allows students to deepen and transfer knowledge. An area that allows for an organic integration of STEM content is through combining mathematics with science instruction. This paper describes how we integrated a lesson coupling flower structure with data representation in a Year 3 classroom. The lesson occurred over…
