The essence of Genetics lies in the understanding of the concepts of Central Dogma of Molecular Biology. Although these ideas are fundamental to the field, they are notoriously difficult to understand and visualize. While simulation-based instructional materials are found to improve the teaching-learning process in science education, little has…

Background: A multimedia software designed as a Computer-Assisted Scaffolding system was used to teach gas behavior on the submicroscopic level using Physics Education Technology Project (PhET) simulation. PhET is a set of interactive, research-based science and mathematics online simulations (https://phet. colorado.edu/). Purpose: The purpose was…

The study aimed to determine the most effective of three pedagogies to improve Grade 12 learners' understanding of the photoelectric effect when the teaching was done using chalk and talk, guided learning with computer simulations (CS) as a demonstration tool and semi-autonomous learning where the learners used the CS individually with limited…

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…

In schools, learning spatial geometry is usually dependent upon a student's ability to visualize three dimensional geometric configurations from two dimensional drawings. Such a process, however, often creates visual obstacles which are unique to spatial geometry. Useful software programs which realistically depict three dimensional geometric…

Contemporary instructional approaches expect students to be active producers of knowledge. This leads to the need for creation of instructional tools and tasks that can offer students opportunities for active learning. This study examines the effect of a computational experiment as an instructional tool-for Grade 12 students, using a computer…
