This study investigates the challenges faced by grade 10 teachers in Engineering Graphics and Design (EGD) classrooms and their impact on learners' performance, particularly related to poor outcomes on the National Senior Certificate (NSC) examination. The study used convenience sampling to select five EGD teachers from two schools offering the…

Interactive Web Environments and multimedia tools are very common in engineering studies. However, these resources are very limited when graphical resolution is needed during the learning process. A learning environment that combines video and self-assessment Computer-Aided Design (CAD) tools was developed to analyse this problem and to determine…

Augmented reality (AR) applications can be used in almost all education and training environments. In this study, it reveals the relationship between perceived usefulness, utility and attitudes regarding the use of AR applications in educational environments as well as the relationship between attitude levels and academic achievements. It also…

This study analyses some published interactive materials for the learning of Spanish as a f?irst language and English as a Foreign Language (EFL) commonly used in primary and secondary education in Spain. The present investigation looks into the relationships between text and image on the interface of Interactive Digital Material (IDM) to develop…

The rapid development of computer graphics technology has made possible an easy integration of dynamic visualizations into computer-based learning environments. This study examines the relative effectiveness of dynamic visualizations, compared either to sequentially or simultaneously presented static visualizations. Moreover, the degree of realism…

A multiple baseline design investigated the effects of computer graphic organizers on the persuasive composition writing skills of four Hispanic students with specific learning disabilities. Participants reviewed the elements of persuasive writing and then developed compositions using a word processing program. Baseline planning was done with a…

Instructions are given for building physical scale models of ordered structures of B-form DNA, protein [alpha]-helix, and parallel and antiparallel protein [beta]-pleated sheets made from colored computer printouts designed for transparency film sheets. Cut-outs from these sheets are easily assembled. Conventional color coding for atoms are used…

This study explored computer animation vignettes as a replacement for live-action video scenarios of classroom behavior situations previously used as an instructional resource in teacher education courses in classroom management strategies. The focus of the research was to determine if the embedded behavioral information perceived in a live-action…

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…

Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how…

The number of experimentally derived structures of cellular components is rapidly expanding, and this phenomenon is accompanied by the development of a new semiotic system for teaching. The infographic approach is shifting from a schematic toward a more realistic representation of cellular components. By realistic we mean artist-prepared or…

A technique is described for the generation of perspective views of three-dimensional models using computer graphics. The technique is applied to models of familiar thermodynamic phase diagrams and the results are presented for the ideal gas and van der Waals equations of state as well as the properties of liquid water and steam from the Steam…

This report describes the operation of a computer monitor called MYCROFT, a system which can debug elementary programs for drawing pictures. The basic skills which are fundamental to debugging skill (description, plan, linearity, insertions, global knowledge, and imperative semantics) are examined. These programs are written for LOGO turtles.…

A study was made of the extent and ways different types of educational software allow young children to manipulate their own actions and, more specifically, to engage in reversible activity. Part 1 of the study consisted of an analysis of the types of reversible actions two kindergarten children engaged in and the actions they wanted to engage in…

Focuses on use of computer-drawn faces to explore visualization in learning and for presenting multivariate data. Prior and new research are reviewed and future applications are discussed. "Autocorrelation-face," a graphics representation created from mathematical analysis of voice input, and its potential as a learning aid for the deaf are…
