Discusses the increased emphasis on problem solving and problem-based learning in instructional design and the need for new methods for task analysis and models for designing instruction. Defines the rationale and means for analyzing, organizing, and presenting stories to support problem solving by case-based reasoning. (Author/LRW)

Discussion of instructional systems development (ISD) focuses on recent developments in cognitive task analysis and describes the Integrated Task Analysis Model, a framework for integrating cognitive and behavioral task analysis methods within the ISD model. Three components of expertise are analyzed: skills, knowledge, and mental models. (96…

ACT-R is a theory of cognition that is capable of learning the relative usefulness of alternative rules. A model using this implicit procedural learning mechanism is described that explains results from a concept formation task created by McDonald and MacWhinney (1991), a role assignment created by Blackwell (1995), and a new role assignment…

One of the author's main goals as a teacher is to impart the skills necessary for students to be successful in science, and that means teaching them how to think and write like scientists. At times, though, it seemed as though the author had exhausted all avenues without ever reaching this goal. At the beginning of each year, she starts her…

In this paper, the term 'intelligence current' is further explained and the problems found in relationships between (among) creativity, intelligence, attitude and environmental factors are discussed, according to the systematic model of creativity previously developed by the author. In this model, the performance of an individual's creativity is…

This study presents results from sentence-completion and grammaticality-judgment tasks with 7 German-speaking agrammatic aphasics and 7 age-matched control subjects examining tense and subject-verb agreement marking. For both experimental tasks, we found that the aphasics achieved high correctness scores for agreement, while tense marking was…

The teaching of human anatomy has had to respond to significant changes in medical curricula, and it behooves anatomists to devise alternative strategies to effectively facilitate learning of the discipline by medical students in an integrated, applied, relevant, and contextual framework. In many medical schools, the lack of cadaver dissection as…

Overview: Behavioural data reveal an inverted U-shaped function in the efficiency of prospective memory from childhood to young adulthood to later adulthood. However, prior research has not directly compared processes contributing to age-related variation in prospective memory across the lifespan, hence it is unclear whether the same factors…

Student motivation within the classrooms is a widely recognized problem and will remain so in the foreseeable future. Literature suggests that students' motivation for learning and performance can be enhanced by creating an appropriate classroom environment, which is again determined by the design of various structural characteristics of a course,…

Event-based prospective memory involves remembering to perform an action in response to a particular future event. Normal younger and older adults performed event-based prospective memory tasks in 2 experiments. The authors applied a formal multinomial processing tree model of prospective memory (Smith & Bayen, 2004) to disentangle age differences…

Using the Luck and Vogel change detection paradigm, we sought to investigate the capacity of visual working memory in 5-, 7-, and 10-year-olds. We found that performance on the task improved significantly with age and also obtained evidence that the capacity of visual working memory approximately doubles between 5 and 10 years of age, where it…

This resource guide for the use of job aids ("how-to-do-it" guidance) for activities identified in the first phase of the Instructional Systems Development Model (ISD) contains an introduction to the use of job aids, as well as descriptive authoring flowcharts for Blocks I.2 through I.5. The introduction includes definitions;…

This paper provides an overview of the cognitive process analysis of tasks used to measure aptitude and intelligence. As an illustration of this approach, performance on inductive reasoning tasks such as series extrapolation and analogy problems is considered in terms of the factors that contribute to item difficulty and individual differences in…

A new, more specific language for describing work activities, based upon the duty module (clusters of tasks that tend to go together occupationally and organizationally in meaningful ways) is being designed for the Army. The purpose is to improve communications between resource and requirement planners and program operators. The paper proposes two…

This study presents a set of hierarchically structured elementary mathematics objectives and delineates the four major steps that lead to the development of the hierarchy. The first is the identification of the major unifying themes that identify the mathematics that will underlie and pervade the rest of the curriculum. The second step is the…
