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,…

In the 11th-grade Vietnamese Mathematics Curriculum, students learn about parallel relations between planes in space. This is cognitively challenging for many students. Studies have shown difficulties relating to limited spatial imagination and drawing representations. The teacher's approach also causes difficulties for some students; for example,…

The research reported here examined the outcome of using interactive simulation technology (IST) as a guided-inquiry approach to enhance learners' conceptual knowledge of electrostatics in physics. Participants were Grade 11 physical sciences learners (n = 60) and a teacher from a rural school in South Africa. Learners were randomly assigned to an…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

This study was conducted to determine the effectiveness of virtual laboratory based on semi second life (s-SL) on higher order thinking skills of general senior secondary school in chemistry learning process. The research design was adopted posttest only design approach to a quasi-experimental. This study was conducted in the one of public general…

Students nowadays grow up with electronic devices and are adept at navigating the virtual world. Practical activities may be more of a novelty for them than simulations. Using the topic of electric circuits as a context, we examined the ways in which Grade 11 students perceived and learned from practical work and simulations, respectively. In this…

Simulations and virtual or remote laboratories are increasingly used in schools. The extent to which individual experimental skills can be acquired when experimenting in digital applications is, however, questionable. This paper focuses on finding multimedia features for digital experiments to support the transfer of measured values from the…

Teachers use different pedagogies to improve learners' performance. The study explored the effect of Computer Simulations (CS) on Grade 11 learners' performance when taught Plants Biodiversity. A Solomon FourGroup design was used to cater for internal and external validity. Sixty-six learners were assigned to two Control Groups (CG) taught using…

Physics is a tough and challenging topic. Facilitating the learning of physics requires an innovative and constructivist view of teaching that promotes an active learning environment and an effective implementation of educational technology. The purpose of the study is to investigate whether the use of computer simulations combined with hands-on…

Virtual reality environments are becoming increasingly popular as educational tools, but it remains unclear when these environments enhance learning or when they are a distraction from the learning process. We compared two different methods for teaching ecological concepts about the rocky intertidal zone by comparing an experimental (virtual)…

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with…

The current research aims to explore the effects of a haptic augmented simulation on students' achievement and their attitudes towards Physics in an immersive virtual reality environment (VRE). A quasi-experimental post-test design was employed utilizing experiment and control groups. The participants were 215 students from a K-12 school in…

Students in 4 Canadian high school physics classes completed instructional sequences in two key physics topics related to motion--Straight Line Motion and Newton's First Law. Different sequences of laboratory investigation, teacher explanation (lecture) and the use of computer-based scientific visualizations (animations and simulations) were…
