Critiques Aptitude-Treatment Interactions (ATI) as a major theoretical foundation for individualized instruction and argues that Content-Treatment Analysis (CTI), which assumes that no one learning treatment is appropriate for all subject content, is more appropriate. It is concluded that CTI should be given a greater role in instructional…

The holistic-discriminability model of object-space perception recognizes various classes of stimuli having different task requirements, with few assumptions. The alternative analytic model, contrary to Dykes and Cooper, is inadequate; it involves many assumptions, predicts only a limited set of data and makes some incorrect predictions.…

Defines courseware engineering (CE) and discusses how it differs from software engineering. Topics addressed include the goals of courseware engineering; a classification of tasks; costs; aspects of knowledge representation; the structure of knowledge in CE; processes in knowledge acquisition; and knowledge base validation. (Contains 48…

A review is offered of various bilingual memory studies that have been carried out during the past quarter century. Most of the studies have employed lexical items as the investigative tool, tested outside of a grammatical or semantic context. (Contains 58 references.) (JL)

Describes a method for trainers to identify critical job requirements or critical behaviors important in doing a job effectively or ineffectively. Suggests ways of recording/describing incidents and presents questions that must be addressed. Reviews steps in the critical incidents process. (CSS)

Mental abilities can be analyzed at four levels: composite tasks, subtasks, components, and metacomponents. Each level of analysis reveals something about the structure and content of mental abilities responsible for intelligent performance. (Author/WI)

Reviews studies on the relationship between task performance and information searching by end-users, focusing on information searching in electronic environments and information retrieval systems. Topics include task analysis; task characteristics; search goals; modeling information searching; modeling search goals; information seeking behavior;…

Presents a process definition of task analysis and discusses how various techniques of analysis--breaking the task into its constituent elements, determining the relationship between these elements, and restructuring for performance and instruction--relate to this perspective. Two decision tables, a master design chart, and 28 references are…

In this report we present the methodology used in a study that investigated the tacit-explicit dynamic in learning processes. We have analyzed an episode related to a discussion about the difference between plane figures and spatial figures promoted by the teacher in her mathematics classroom (the students are aged 11 to 12). The data analysis was…

The authors explore federal learning disabilities (LD) guidelines, Wisconsin LD guidelines, and current educational research relating to approaches for teaching LD students. Two approaches are considered--the process-deficit approach and the task-analytic approach. (SBH)

Examines the functional characteristics of intelligent computer-assisted instruction (ICAI), proposes a structural model that defines expertise requirements for the development of an ICAI system, and discusses the requirements of a multidisciplinary cooperative effort for its development. Knowledge acquisition, learning needs, and instructional…

Reports on a study that investigated metacognitive strategy use by a pair of students working with a computer database. Strategies are inferred from analysis of the discourse, and features of a metacognitive environment are discussed. (13 references) (GLR)

Describes differences in formative evaluation techniques between instructional designers and subject matter experts. Content analysis based on think-aloud data focusing on differences in task interpretation, problem identification and revision statements, and review strategies is discussed; use of instructional systems design models by…

Discussion of expert systems focuses on knowledge acquisition methodologies and their potential application to cognitive science research and the development of instructional materials. Topics discussed include subject matter experts; types of knowledge; structured interviews; task analysis; intelligent computer assisted instruction (ICAI);…
