This article presents the results of a 7th-grade classroom teaching experiment that supported students' understanding of integer addition and subtraction. The experiment was conducted to test and revise a hypothetical learning trajectory so as to propose a potential instructional theory for integer addition and subtraction. The instructional…

For the forty-fourth time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented online and onsite during the annual AECT Convention. Volume 1 contains papers dealing primarily with research and development topics. Papers dealing with…

Graphical representations (GRs) of the learning content are often used for instruction (Ainsworth, 2006). When used in learning technology, GRs can be especially useful since they allow for interactions across representations that are physically impossible, for instance by dragging and dropping symbolic statements into a chart that automatically…

Describes an instructional model, Strategies Program for Effective Learning/Thinking (SPELT), that was developed to translate cognitive psychological theory and research into a practical instructional program. The extent to which SPELT conforms to current instructional design principles is examined, and macro versus micro instructional sequencing…

In this paper the design of a workflow support tool for competence based distance learning in a group setting is discussed. The design is based on a stakeholder analysis and crash-tested in an actual course setting. Preliminary findings suggest that some well-known problems have been solved, but further more in depth research is needed to assess…

Discusses the nature and sequencing of decisions involved in designing a game, simulation, or workshop from the theoretical perspective of course and curriculum design. A model for design is presented that incorporates objectives, teaching/learning methods, content, and assessment/evaluation, and other models are also discussed. (Author/LRW)

Discussion of control over sequence of instruction in computer-assisted instruction (CAI) focuses on a follow-up study that examined the effects of the breadth and depth of menus and the meaningfulness of menu category names on the learning and attitudes of college students. Posttests are described, and results are analyzed. (16 references) (LRW)

Description of a study which formulated a model of the cognitive processes involved in learning statistics material via computer assisted learning (CAL) focuses on mode of presentation (aural or visual), sequence of the material, and previous mathematical experience. Textual analysis is discussed and implications of the results for design of CAL…
