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…

Over the last 20 years, virtual microscopy has become the predominant modus of teaching the structural organization of cells, tissues, and organs, replacing the use of optical microscopes and glass slides in a traditional histology or pathology laboratory setting. Although virtual microscopy image files can easily be duplicated, creating them…

In an attempt to evaluate the impact of the use of a simulation on the learning concepts of relative dating, a study was carried out with first year students at the Technical High School of the city of Taza (Morocco). The method of the study was semi-experimental research design with pre-test and post-test. The study used two groups including the…

This work presents a three-dimensional (3D) modeling exercise for undergraduate students in chemistry and health sciences disciplines, focusing on a protein-group linked to immune system regulation. Specifically, the exercise involves molecular modeling and structural analysis of tumor necrosis factor (TNF) proteins, both wild type and mutant. The…

Species TOPOS is a free software package for generating three-dimensional (3-D) topographic surfaces ("topos") for acid-base equilibrium studies. This upgrade adds 3-D species distribution topos to earlier surfaces that showed pH and buffer capacity behavior during titration and dilution procedures. It constructs topos by plotting…

The QuVis Quantum Mechanics Visualization Project provides freely available research-based interactive simulations with accompanying activities for the teaching and learning of quantum mechanics across a wide range of topics and levels. This article gives an overview of some of the simulations and describes their use in an introductory physical…

Indonesia and many other developing countries have a vast youth population, yet limited facilities for physics learning. The major purposes of this study are to develop low-cost, technology-enhanced physical and virtual laboratories and to investigate their effects on various learning objectives, including conceptual understanding, inquiry…

The concept of "seeing by feeling" as a way to circumvent limitations on sight is universal on the macroscopic scale--reading Braille, feeling one's way around a dark room, etc. The development of the atomic force microscope (AFM) in 1986 extended this concept to imaging in the nanoscale. While there are classroom demonstrations that use…

Cruise planning may seem like an ordinary task for oceanographers, but it actually involves logical and strategic thinking, collaboration, and multidisciplinary work. The "Challenger" expedition, led by Charles Wyville Thomson from 1872 to 1876, was the first to be fully dedicated to understanding oceans (Rice et al. 1999) and was…

This article outlines a study that compared an online virtual laboratory with a face-to-face laboratory. The main objective of the study was to evaluate the effectiveness of a virtual method of instruction for a general studies, physical science laboratory course. Using a pretest-posttest only design with nonequivalent control groups, differences…

The use of simulators and customized applications for educational use opens new possibilities in the teaching and learning process of the most varied disciplines through computer-mediated interactions. In this context, teachers are developing digital material considering this powerful tool. And the use of educational apps and simulators has…

The goals of the study were (a) to compare the instructional effectiveness of immersive virtual reality (VR) versus a desktop slideshow as media for teaching scientific knowledge, and (b) to examine the efficacy of adding a generative learning strategy to a VR lesson. In Experiment 1, college students viewed a biology lesson about how the human…

Mutation, diversity, natural selection and the biology of human pathogens (including antibiotic resistance) are key features of the biosciences curriculum at A Level and undergraduate study. Few resources exist to allow students to engage with these topics in an interactive manner. This paper describes an interactive, online simulation of mutation…

Laboratories studying the anisotropic rotational diffusion of bromobenzene using nuclear spin relaxation and molecular dynamics simulations are described. For many undergraduates, visualizing molecular motion is challenging. Undergraduates rarely encounter laboratories that directly assess molecular motion, and so the concept remains an…

As students increasingly use online chemistry animations and simulations, it is becoming more important to understand how students independently engage with such materials and to develop a set of best practices for students' use of these resources outside of the classroom. Most of the literature examining students' use of animations and…
