When preschool teachers attempt to initiate play-responsive science teaching, opportunities arise to develop or challenge the play further, for example, by introducing or focusing on science content. The aim of this article is to generate knowledge about how projected images and videos can be used in attempted play-responsive science teaching and…

This study focuses on how science teachers' Pedagogical content knowledge (PCK) can be captured and developed with the support of Content representation (CoRe) in combination with video-based reflection when they plan, teach, and reflect on their teaching in sustainable development (SD). The theoretical framework is based on PCK, and the Refined…

Oblique angle collisions of two penny coins on a smooth, horizontal surface were filmed with a video camera to investigate the physics of the collision process. If one of the coins is initially at rest, then the two coins emerge approximately at right angles, as commonly observed in billiard ball collisions and in puck collisions on an air table.…

Measurements and calculations are presented showing how the trajectory of an object sliding across an inclined plane varies with the launch and incline angles. The trajectory depends on the magnitude and direction of the sliding friction force. The experiment is easy to set up, can be analysed using a video camera, and would be suitable for a…

This randomized controlled trial assessed the comparative effectiveness of a biochemistry education program delivered through an immersive virtual reality (iVR) experience and traditional video-based instruction. Undergraduate students enrolled in three nutrition courses from a large R1 American university participated (n = 95). Students were…

The accurate and precise transport of the small amounts of the liquid by the syringe pump is widely used in many fields. In this paper, an Arduino-based syringe pump is fabricated using the computer DVD (digital versatile disc) drive. For the fabrication of the syringe pump, low-cost electronic components such as an Arduino microcontroller, a…

The aim of this research was to provide preschool children with context-based science and nature activities and basic process skills. The research was carried out with 11 children aged 48-60 months in the second term of the 2019-2020 academic years. The research was designed according to action research, one of the qualitative research designs. In…

Background: Effective science teaching requires a specialised body of knowledge. Researchers have recognised the importance of understanding the incoming knowledge that pre-service science teachers (PSTs) bring to their initial teacher education. However, although many studies have focused on PSTs' declarative knowledge or the knowledge that…

Atomic-level visualizations serve as pivotal instructional tools in chemistry education, providing insights into the particulate level of matter, a dimension fundamental, yet typically invisible, in the study of chemistry. This research investigates how students' engagement with these visualizations influences their conceptual understanding of…

The aim of this study is to investigate the effects of the flipped classroom model on the academic success and 21st century skills of middle school students in the unit of systems in our body. The study was conducted with 6th grade students studying in a state school in Istanbul. In the study, an applied study was conducted with two experimental…

Taking the "practice turn" in K-12 science classrooms requires students to engage in processes of knowledge building, constructing explanatory accounts of natural phenomena. To support students in these sensemaking opportunities, a significant departure is needed from how science is typically taught in many classrooms. Teachers will need…

Points near the top end of a falling rod hinged at its bottom end can fall faster than g. If a rod falls on a frictionless surface then the bottom end slides backwards and the centre of mass falls vertically with acceleration less than g. The effect was simulated by mounting a rod on wheels and filming the result with a video camera. The…

Clear, detailed instructional procedures have an important role to play in laboratory teaching to not only produce consistent results but also ensure safe practices. Student success in using these procedures can be strengthened through the use of video resources. However, not all video content will have the same impact. Videos must have sufficient…

Guided by the 5E framework (Engage, Explore, Explain, Elaborate, Evaluate), a buffer solution courseware was designed using "Articulate Rise," a content authoring tool. It was deployed in a freshman general chemistry course in the April semesters of 2022 and 2023. The courseware was a supplementary resource to support instructor-created…

This mixed-methods study examines how pre-service teachers select instructional videos on YouTube for physics teaching. The study focuses on the role of surface features that YouTube provides (e.g., likes, views, thumbnails) and the comments underneath the videos in the decision-making process using videos on quantum physics topics as an example.…
