This study investigated the effect of immersive virtual reality (VR) on 11th-grade students' creative thinking disposition (CTD) and academic achievement in chemistry. A quasi-experimental pretest-posttest non-equivalent control group design was employed, involving 86 students (36 males and 50 females) aged 16-18 years from a public senior high…

The image of free-falling bar has been recorded to study the effect of the motion on its observed length. This moving bar image is analysed using the Tracker software to determine its length and the end bar's position. An elongated appearance of the bar has been observed with movement. This effect relies on the speed and the exposure time during…

In this article we present a simple experimental set-up to determine the band gap of germanium and silicon using the "ExpEYES-17" kit. The experiment is based on the temperature dependence of the reverse current through germanium and silicon diodes at different temperatures. The experimental values are found to agree well with accepted…

Herein, two simulated electrochemistry experiments, namely, the (i) electrochemical series, using an electronic half-cell module, and (ii) citrus fruit battery series are demonstrated for undergraduate chemistry students. The demonstration can be performed for in-person and remote students by connecting the electronic half-cell module to a…

Circulatory system is a challenging subject for middle school students to learn and understand conceptual relationships. To address these challenges, this study developed plugged (computational thinking activities using computer) and unplugged (computational thinking activities without using computer) teaching modules that integrated computational…

In the post-COVID-19 era, information education with highly interactive teaching methods has become increasingly common. In particular, the metaverse and virtual reality (VR) technology can be used in novel learning methods to leverage the intuitiveness, immersivity, and interactivity of VR. For example, students could use VR to simulate…

Air pollution is one of our day's significant reasons for human health problems and affects every community throughout the world. Monitoring air pollution is a key aspect of raising awareness and pollution mitigation approaches followed by different nations. This paper targets to develop a low-cost Internet of things-based embedded system to…

As I approach my 70th year in physics, let me tell my younger colleagues about my adventures with computation. When I was 14, my father gave me a slide rule because I appeared to be headed toward a career in physics. Since then, I have had experience with many other calculating devices.

Electricity, especially the flow of current, is a challenging topic for students of all ages. This study conceptualizes students' explanation of electric current as a cluster of knowledge elements. These clusters, in turn, represent students' mental models of electric circuits. Thus, this study aims to identify and characterize students' mental…

Synthesis and diffusion of a pigment molecule can be simulated using deterministic equations in computer software. These lesson materials describe how tiger stripes emerge from manipulations in this code, and how students can engage in mathematical inquiry by exploring these reaction-diffusion equations.

Interest in virtual laboratory simulations as a pedagogical tool continues to grow, given the advantages of flexibility, scalability, technology integration, and interactive visualizations. We developed a laboratory model that integrates virtual lab simulations (VLS) and traditional in-person (IP) lab experiences for targeted skill development. In…

Many technological applications (apps) purport to help children learn academic material. Building on research in developmental and educational psychology, we developed and tested an app to teach biological and physical science content to preschool children. There were 21 children in the control condition (M[subscript age] = 50.30 months, SD =…

This study explores multilingual study guidance (MSG) teachers design for learning and the potential of immersive and interactive Virtual Reality (VR) technology to support students' development of disciplinary knowledge through multilingual conceptual learning. Part of a co-design research project, the study draws on two teachers' didactical…

In this work, we report the development of a low-cost Arduino-controlled device for didactic activities in light polarization. The main body of the prototype was designed and produced using laser-cut medium density fibreboard parts, including gears and pulleys. As a light source and detector, a 532 nm laser pointer and a light dependent resistor…

Physics classes with computation integrated into the curriculum are a fitting setting for investigating computational thinking. In this paper, we present a framework for exploring this topic in introductory physics courses. The framework, which was developed by reviewing relevant literature and acquiring video data from high school classrooms,…
