Digital learning tools and laboratory simulations have been an area of great interest not only due to the advancements of at-home learning but also by allowing students and institutions access to experiences they would not have otherwise due to the high cost of commercial instrumentation. The need for online learning tools became especially…

The study aimed to investigate the effect of computer simulation and animation-integrated instruction on preservice science teacher trainees' conceptual understanding and retention of acid-base chemistry and stoichiometry. A quantitative approach with a pretest-posttest-delayed test quasi-experimental design was used. In the study area, there were…

One of the critical goals of teaching chemistry is to enable learners to gain conceptual understanding. Traditional instruction has often been associated with rote memorisation, resulting in learners failing to explain observed chemical phenomena, make predictions based on acquired concepts, advance convincing arguments, and engage in meaningful…

Background: Blended mathematical sensemaking in science ("MSS") involves deep conceptual understanding of quantitative relationships describing scientific phenomena. Previously we developed the cognitive framework describing proficiency in MSS across STEM disciplines, and specifically Physical Science. The framework was validated with…

Theoretical and practical foundations of basic electrochemical concepts of heterogeneous charge transfer reactions that underline electrochemical processes are presented for their detailed study by undergraduate and postgraduate students. Several simple methods for calculating key variables, such as the half-wave potential, limiting current, and…

This study, titled "The Effect of Computer Simulation on Grade 11 Learners' Conceptualisation of Stoichiometric Chemistry," was carried out at a school in the Frances Baard District of the Northern Cape province of South Africa. Poor conceptualisation of stoichiometric chemistry by learners in Grades 10-12 in South Africa and, hence,…

While augmented reality (AR) technology has shown the potential to facilitate students' hands-on activities, few studies have explored its effectiveness in acoustic topics. This paper introduces an AR-based application for learning about the Doppler effect and investigates its educational effectiveness on students' learning achievement, interest,…

From the experiential learning perspective, this study investigates middle and high school students (n = 1009) who used an online module to learn about wildfire hazards, risks, and impacts through computational simulations of wildfire phenomena. These students were taught by 18 teachers in urban, rural, and suburban schools across the United…

This mixed methods study explored how the making of animated models affected year 11 students' understanding of the effect of temperature on the equilibrium of an exothermic or endothermic reaction. The students' perspectives and the role of the activity in facilitating a metacognitive process were also examined. Teacher perspectives were also…

In recent years, chemistry educators are increasingly adopting immersive virtual reality (IVR) technology to help learners visualise molecular interactions. However, educational studies on IVR mostly investigated its usability and user perceptions leaving out its impact on improving conceptual understanding. If they evaluated students' knowledge…

The purpose of this study is to analyze the mental model of improvement and changes on light wave concepts with Conceptual Change based on Virtual Media (CC-VM) x POE strategy. The method used is mixed methods with embedded design. The sample consisted of 30 students (with an age range of 16-17 years) in one of the schools in Subang, Indonesia.…

When thinking about measurement uncertainty in a laboratory experiment that features quantum mechanical effects, it is important to consider both the physical principles of underlying quantum theory (e.g., the uncertainty due to quantum mechanical superposition states) as well as the limitations of the measurement (e.g., the spread in outcomes due…

Augmented reality (AR) provides students with visual, auditory, and concrete learning understandings that facilitate their understanding of abstract concepts, leading to positive experiences in the learning process. Positive experiences increase students' motivation and interest in learning. This study examined the effects of using AR technology…

Even though physical experiments are mandatory in science education, there has been an increasing demand for virtual experiments. This research aimed to investigate the impact of virtual experiments compared to physical experiments on students' conceptual understanding of chemical kinetics concepts. To achieve this, a two-phase explanatory…

This article describes the design and evaluation of a simulation environment for special relativity (SR) education at the secondary level. In recent years, SR has become increasingly popular in secondary school curricula worldwide. Because the key concepts in SR are very remote from everyday experience, they are difficult for students to learn.…
