This paper presents both the design and the pilot formative evaluation study of a computer-based problem-solving environment (named LECGO: Learning Environment for programming using C using Geometrical Objects) for the learning of computer programming using C by beginners. In its design, constructivist and social learning theories were taken into…

The aim of various approaches implemented, whether the classical "three Ps" (presentation, practice, and production) or communicative language teaching (CLT), is to achieve communicative competence. Although a lot of software developed for teaching spoken English is dressed up to raise interaction, its methodology is largely rooted in tradition.…

Information technology (IT) has the potential to improve the clinical learning environment. The extent to which IT enhances or detracts from healthcare professionals' role performance can be expected to affect both student learning and patient outcomes. This study evaluated nursing students' satisfaction with a novel compartmental Picture…

This paper investigates the uses of various kinds of hypermedia format for history learning, which specifically emphasizes on the role of causal reasoning about history accounts. Three different groups in the last school year of Secondary Education (aged 16) studied the same materials about the Discovery of America in three different formats: (a)…

Trainers interested in enhancing computer-assisted instruction with graphics should ask (1) What are the training objectives? (2) What technologies serve these purposes? and (3) What is the most cost-effective alternative? (SK)

A description of two devices that "could provide computer-assisted input and output in graphic form, could supply several types of recording and storage, and could be operated at a distance." (Author/AK)

Discusses the importance of accurate graphic presentation and describes graphs available on "LabQuest" computer software. Highlights include graphing conventions; prerequisites for computer graphing; bar graphs; pie graphs; stacked bar graphs; line graphs; x/y graphs; scatter graphs; box plots; stem and leaf graphs; best fit graphs; and…

This research aims to explore the role of physical representations in young children's numerical learning then identify the benefits of using a graphical interface in order to understand the potential for developing interactive technologies in this domain. Three studies are reported that examined the effect of using physical representations…

This paper reports on a case-study design experiment in the domain of fraction as number-measure. We designed and implemented a set of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. Two groups of 12-year-old students worked collaboratively using paper and pencil as well as a specially…

This research describes preservice teachers' perceptions of the use of applets in solving mathematical problems. It examines such perceptions regarding the role and functions that applets have in the problem solving context, the difficulties they encounter when using applets in this context and the necessity or need of their use. I attempt to…

Three examples of how the computer terminal can be used to provide the kind of "pictorial" information that makes graphs such a valuable aid in the teaching of quantitatively oriented subjects are presented. In the first example the graph is part of the "frame" of information presented to a student in a tutorial which reviews…

This article examines three important facets of the incorporation of new technologies into educational practice, focusing on emergent usages of the mathematical tools of computer algebra and dynamic geometry. First, it illustrates the interpretative flexibility of these tools, highlighting important differences in ways of conceptualizing and…

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…

An experimental study involving 30 undergraduates (mean age = 20.5 years) in mental rotation (MR) training was conducted in an interactive Desktop Mental Rotation Trainer (iDeMRT). Stratified random sampling assigned students into one experimental group and one control group. The former trained in iDeMRT and the latter trained in conventional…
