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…

Differences in performance with various stimulus-response mappings are among the most prevalent findings for binary choice reaction tasks. The authors show that perceptual or conceptual similarity is not necessary to obtain mapping effects; a type of structural similarity is sufficient. Specifically, stimulus and response alternatives are coded as…

This article proposes a theory- and practice-based model for adapting physical activities. The ecological frame of reference includes Dynamic and Action System Theory, World Health Organization International Classification of Function and Disability, and Adaptation Theory. A systematic model is presented addressing (a) the task objective, (b) task…

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…

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…

The instructional model presented describes a system which is now being implemented by the United States Navy, but can be generalized to educational program development in other areas. (Author)

The contrasting approaches of differential psychology and cognitive psychology to the same individual differences data are outlined. Using data from the Clark and Chase sentence-picture verification task, four loci of conflict between these two disciplines are identified: (1) theory versus measurement; (2) meaningfulness versus reliability; (3)…

Discussed are the relative merits of two currently popular models of assessing children--the ability assessment and task analysis models. (CL)

Presents a situation by response model that enables trainers to organize and simplify the planning, training, and application of making appropriate response choices. The discussion covers the possible uses of the model and the necessary steps involved in the creation of the model. (CLB)
