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…

When visualization tools utilized in computer programming education have been evaluated empirically, the results have remained controversial. To address this problem, we have developed a model of short-term effects of program animation, and used it in a series of experiments. In the current experiment, we varied visual representation of an…

This article is a review of the pedagogical experience obtained with systems for algorithmic animation. Algorithms consist of a sequence of operations whose effect on data structures can be visualized using a computer. Students learn algorithms by stepping the animation through the different individual operations, possibly reversing their effect.…

One of the psychological states that can be monitored and influenced during learning in order to improve its various aspects is the state of anxiety, and one possible index of this state is frontal EEG beta. However, frontal EEG beta has also been associated with mental activities. This may imply that frontal EEG beta would not be a reliable index…

Pathfinder is a graphic theoretic technique used to analyze proximity data. This study evaluates its validity: (1) for representing and comparing individuals' navigation through a computer-based hypermedia environment; and (2) for generating an empirically-derived path that represents a set of individual navigational paths during computer-assisted…

The purpose of this study was to compare the relative effectiveness of live (SERT) and computer-based (iSTART) reading strategy training. Prior to and after training, participants read scientific texts and self-explained after each sentence. They also answered comprehension questions. Students showed improvement in the quality of their…

Reviews research on uses of computer sound and suggests how sound might be used effectively by instructional and interface designers. Topics include principles of interface design; the perception of sound; earcons, both symbolic and iconic; sound in data analysis; sound in virtual environments; and guidelines for using sound. (70 references) (LRW)

Provides a meta-analysis on the effect of computer-assisted instruction (CAI) over a range of study features with a focus on the effectiveness debate. Suggests that what accounts for the typical learning advantage of CAI is the better quality instruction provided by CAI materials. (Author/AEF)

Suggests a set of cumulative standards for assessing the use of nonprint media and electronic technologies in elementary, middle, and high school classrooms. Discusses technology integration across the curriculum; standards for technology integration; and the development of nonprint literacy performance standards. (Contains 15 references.)…

This article discusses the effectiveness of a theoretical-based integrated learning environment (ILE) for training non-traditional learners to perform the skills required to be successful in entry-level jobs. The ILE places instruction in a real-world, workplace context with realistic settings, characters, and storylines. The multimedia interface…

The most recent advances in information technology have brought wireless communication and mobile devices to education. The wireless technology enhanced classroom (WiTEC) integrates a wireless local area network, mobile learning devices, and client-server architecture to support instruction and learning activities. This article introduces a…

Examines changes which have occurred in the development and evaluation of intelligent tutoring systems (ITSs), speculates on future directions, and proposes a conceptual model for the development of ITSs. Topics discussed include the effectiveness of ITSs; the need for multidisciplinary efforts; and internal and external evaluation. (Contains 78…

Describes the West Virginia K-12 RuralNet project which provides inservice teacher training to public school teachers on the use of Internet resources and presents a summary of quantitative and qualitative evaluation. Explains the validation of two instruments, the Level of Use of Internet and the Personal Internet Teaching Efficacy Beliefs Scale.…

Course management systems (CMSs), such as Blackboard, Desire2Learn, or WebCT, have become a common resource at universities, colleges, and distance learning organizations. Research into how these systems are used for learning is in an early state. Currently, this research focuses on technical features in a CMS more than research about how people…

This study investigated factors affecting second/foreign language (L2) reading comprehension in a hypermedia environment within the theoretical framework of dual coding and cognitive load theories, and interactive models of L2 reading. The independent variables were reading ability, topic interest, prior topical knowledge, and the number of times…
