Purpose: This study reports on the effectiveness of using animated computer graphics to teach submicroscopic level science to secondary school (Form One) students. Method: A total of fifty-three secondary school (Form One) students of average spatial ability were selected to participate in this study. Three topics involving concepts at the…

The low achievement of chemistry students in Nigerian Colleges of Education has been attributed to a number of factors including a lack of indigenous computer software for enhancing course teaching. This study therefore sought to develop and validate an instructional computer package on organic chemistry for Colleges of Education in Nigeria. The…

In this study, we investigated the optimal placement of animations and practice and feedback exercises with respect to each other and to static text and graphics in an online DNA replication module. We randomly assigned students in a first-semester introductory biology course for freshmen biology majors and nonmajors to one of four online modules…

The research study sought to determine the effect of tailored animated motion sequences on teaching, performance and visual literacy in Biology learners. The animations were developed as per the Grade 8 Biology syllabus hence referring to the term 'tailored motion graphic's' using the ADDIE design model. This mixed-methods study included a series…

The authors have developed a computer-based learning module on the unit cell of various types of crystal. The module has two components: the virtual unit cell (VUC) part and the subsequent unit cell hunter part. The VUC is a virtual reality simulation for students to actively arrive at the unit cell from exploring, from a broad view, the crystal…

This study is part of an ongoing research project examining middle school girls' attention to and interpretation of visual representations of DNA replication. Specifically, this research examined differences between two different versions of a multimedia presentation on DNA, where the second version of the presentation was redesigned as a result…

The purpose of this study was to develop a framework for analyzing and evaluating student-constructed models of physical phenomena and monitoring the progress of these models. Moreover, we aimed to examine whether this framework could capture differences between models created using different computer-based modeling tools; namely, computer-based…

The present investigation was designed to determine if the learning benefits of metaphors and graphics could be combined into one instructional device--a metaphorical graphic--to aid in the acquisition of difficult concepts of chemistry. The authors further sought to determine if metaphorical graphics could foster greater retention of the basic…

Within the framework of cognitive learning theories, instructional design manipulations have primarily been investigated under tightly controlled laboratory conditions. We carried out two experiments, where the first experiment was conducted in a restricted system-paced setting and is therefore in line with the majority of empirical studies in the…

Changing practices in schools is a very complex endeavor. This paper is about new practices we prompted to foster collaboration and critical reasoning in science classrooms: the presentation of pictures representing different perspectives, small group synchronous argumentation, and moderation of synchronous argumentation. A CSCL tool helped in…

A simple interface between VPython and Microsoft (MS) Office products such as Word and Excel, controlled by Visual Basic for Applications, is described. The interface allows the preparation of content-rich, interactive learning environments by taking advantage of the three-dimensional (3D) visualization capabilities of VPython and the GUI…

Our main goal in this study was to determine whether the use of computer animation and illustration activities in high school can contribute to student achievement in molecular genetics. Three comparable groups of eleventh- and twelfth-grade students participated: the control group (116 students) was taught in the traditional lecture format,…

This paper is a study on the interaction patterns of distance learners enrolled in the Mathematics and Physics programmes of Universiti Sains Malaysia in the videoconferencing learning environment (VCLE). Interaction patterns are analysed in six randomly chosen videoconferencing sessions within one academic year. The findings show there are more…

The increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables…

Learning embryology remains difficult, since it requires understanding of many complex phenomena. The temporal evolution of developmental events has classically been illustrated using cartoons, which create difficulty in linking spatial and temporal aspects, such correlation being the keystone of descriptive embryology. We synthesized the…
