Over the past decades, researchers have investigated the effects of multimedia design principles to enhance learning. These evidence-based principles are known to enable students to learn from multimedia resources and support cognitive processing. However, it is unclear if and which of these multimedia design principles are implemented in…

One of the main goals of lower division "service" mathematics courses is to provide STEM-intending students with opportunities to engage in activities and contexts that can support their efforts to apply the mathematical ideas they are learning to successive major courses. The Mathematics Association of America has supported many…

The conical pendulum is a topic theoretically approached in physics literature, but with little experimental activity developed due to the difficulty of reproducing the conical motion in ideal experimental conditions. This work consisted of studying the motion of a rigid conical pendulum using video analysis. The experimental results were used as…

This study investigated the impact of the flipped classroom on grade six students' academic achievements and perceptions in science class. Participants (n = 39) were assigned to a control group (using traditional instruction) or an experimental group (using flipped instruction). Data analysis was done using Statistical Package for the Social…

This article provides rich insights into the process of data generation for discourse analysis from three separate studies of the video recordings of a single science classroom in action. The central claim is that multimodal transcription can contribute to developments in discourse theory. A three-stage reflective heuristic is developed and used…

Digital video has become a dominant form of student learning in and beyond the classroom, and thus its pervasive nature in contemporary learning environments commands scholarly inquiry. In this paper we explore a participatory design-based research approach to the integration of video hook technology in the post-primary science classroom (students…

The infrared camera, or thermal imaging camera, can be used to complement the teaching of a number of topics in high school science. Here, we provide seven examples of its application in teaching physics, chemistry and biology concepts at high school level. We also discuss its strengths for such applications and provide some pointers for science…

A vacuum cleaner is used to isolate over twelve harmonics in a corrugated toy whistling tube. The toy tube is first taped along a horizontal surface. Then a vacuum cleaner with a hose diameter approximately the same as that for the toy tube is turned on. As the vacuum cleaner hose approaches one end of the corrugated tube, individual higher…

While expository texts are an efficient and dominant genre used by science teachers in the United States, they generally lack justification for their claims and fail to reflect science as practice. In contrast, epistemically considerate texts detail specific scientific experiments, providing the reader insight into the methods and data of a…

Learning to teach is a culturally situated activity. As teachers learn, it is important to understand not only what teachers learn, but how they learn. This article describes a qualitative case study of a subset of four teachers' learning during a professional development surrounding a plate tectonics curriculum. Using qualitative methods, this…

Geographic context is important for Earth Science education but different places have different geological complexities and effectively establishing geoscientific context can be difficult. Well-designed videos can help geoscience educators introduce geologically significant places to undergraduate geoscience students. However, there is no…

Schools operated mostly in online mode in the last two years because of the COVID-19 pandemic and many teachers are now using digital tools in physical classrooms after the reopening of schools. We conducted an experiment on how smartphones can be used to reinforce biology lessons of seventh standard students (mean age = 12.22 years) in a private…

This project report highlights a simple yet effective outreach lab benefiting the community partner, specifically the Alameda Point Collaborative (APC) youth program and Saint Mary's College students in a general science course. Building on a partnership focused on reciprocity, a portable lab experiment (Mattson Microscale Gas Chemistry lab) was…

Teaching a field experience course during a pandemic resulted in unique challenges because preservice teachers could not visit classrooms like they would in a traditional field experience. This article is a self-study exploration of the tensions experienced by a doctoral student teaching an elementary math and science field experience in a fully…

Ability to adequately analyze educational situations is essential not only for (pre-service) teachers' occupational decisions, but also for their own professional development. This study represents an evaluation of the observation practice aimed at pre-service chemistry teachers' (N = 12) professional vision development. They attended chemistry…
