Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

This paper focuses on one method used to introduce model design and creation using StarLogo to a group of high school teachers. Teachers with model-building skills can easily customize modeling environments for their classes. More importantly, model building can enable teachers to approach their curricula from a more holistic perspective, as well…

Describes the use of a simulated learning environment (SLE) as an instructional aid in teaching multivariate statistics, particularly inferential statistics. A prototype microcomputer-based SLE called MVWORLD developed at Drexel University for upper level statistics courses is explained, and implementing a statistics laboratory for multivariate…

Description of computer-based simulations focuses on the instructional functions of simulations and phases in the learning processes that should be activated by educational simulations. Highlights include a general model for simulation design; degree of learner control; complexity of the content; the role of the learner; and motivational…

Discusses the development of an abstract model for hypermedia test guides. The model uses an object-oriented approach and is built on the declarative foundation of first-order logic. This method produces a model that is easy to construct and extends to cover new media technology. (Contains 27 references.) (JLB)

Discussion of how to teach thinking and problem-solving skills focuses on a study of seventh graders that attempted to convey expertlike behavior using LEGOLogo to explain how a washing machine operates. Topics addressed include concept representation and mental models; cognitive apprenticeship; and LEGOTClogo as a learning environment. (Contains…

A text production model is considered as an instrument for researching the writing strategies of abstractors. Within this framework, abstracting is a subtype of the writer's activities, which are described in terms of text actions. A computer system can be constructed that evaluates and/or supports human text production. (Author/AEF)

Describes a computer-based simulation model that can be used for the training of higher education administrators. Simulation games as instructional and training models are discussed; weighted alternatives used in the model are explained; validation is discussed; and the architecture of the computer simulation is described. (10 references) (LRW)

Develops a new model for a process that generates Lotka's Law. Topics include measuring scientific productivity through the number of publications; rate of production; career duration; randomness; Poisson distribution; computer simulations; goodness-of-fit; theoretical support for the model; and future research. (Author/LRW)

Although computer modelling is widely advocated as a way to offer students a deeper understanding of complex phenomena, the process of modelling is rather complex itself and needs scaffolding. In order to offer adequate support, a thorough understanding of the reasoning processes students employ and of difficulties they encounter during a…

Despite a long tradition, conventional anatomy education based on dissection is declining. This study tested a new virtual reality (VR) technique for anatomy learning based on virtual contrast injection. The aim was to assess whether students value this new three-dimensional (3D) visualization method as a learning tool and what value they gain…

In social studies classes, there is a longstanding interest in how societies evolve and change over time. However, as stories of the past unfold, it is often difficult to identify a direct link between causes and effects, so students are forced to accept at face value the interpretations of economists, political scientists, historians,…

The XX IDEA annual conference has been focused and reflected on different ways and means of meeting various kinds of methodological challenges, new technologies and multi-media developments, newly emerging partnerships and collaboration between emerging sectors on one hand and between the institutions functioning with similar objectives and…

Computational science includes the use of computer-based modeling and simulation to define and test theories about scientific phenomena. The challenge for educators is to develop techniques for implementing computational science in the classroom. This paper reviews some previous work on the use of simulation alone (without modeling), modeling…

Arguing that what sets the computer apart from all other teaching devices is its potential for interactivity, this paper examines the concept of interactivity and explores ways in which its power can be harnessed and put to work. A discussion of interactivity in human-to-human communication sets a context within which to view human/computer…
