Details a three-dimensional model developed by Control Data Education Services which provides for analysis of project needs, staffing project personnel, and tracking project tasks. Document support for implementing the model and staffing considerations are defined. (RAO)

The model stresses interactions among specific combinations of cognitive task requirements, learner characteristics, and instructional treatment properties, in a manner analogous to the aptitude-treatment interaction (ATI) model. "Supplantation" is the provision of overt assistance to learners in performing a specific process required 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);…

Describes a model of information processing that could be helpful in teaching students to interpret information. Four stages of information processing are discussed: judging suitability, understanding/comprehending, evaluating, and extracting. Examples based on task analysis and observations of students' work are included. (three references) (MES)

Schwa epenthesis and schwa deletion are two types of phonological variation that occur frequently in Dutch. In this study, a series of picture-naming experiments investigated whether schwa epenthesis and schwa deletion are arbitrary processes or whether they are contextually driven and take place in speech-planning process. Findings are discussed…

Magnitude is assumed to be represented along a holistic mental number line in adults. However, the authors recently observed a unit-decade compatibility effect for 2-digit numbers that is inconsistent with this "holisticness" assumption (H.-C. Nuerk, U. Weger, & K. Willmes, 2001). This study used the compatibility effect to examine whether the…

A number of experimental data have shown that naming latency increases with length for pseudo-words but not for frequent real words. Different interpretations have been proposed by current models of reading to account for such a length effect. The aim of the present study was to assess the impact of lexicality on length effect in both the reading…

Cognitive task analysis grew out of efforts by cognitive psychologists to understand problem-solving in a lab setting. It has proved a useful tool for describing expert performance in complex problem solving domains. This review considers two general models of cognitive task analysis and examines the procedures and results of analyses in three…

A review of the literature related to methods for analyzing content or tasks prior to instructional development is presented. The review classifies methods according to a two-dimensional matrix. The first dimension differentiates phases of analysis, each dealing with content and tasks of a particular scope and each generating certain…

The learning machine described in this paper acquires concepts representable as conjunctive forms of the predicate calculus and behaviors representable as productions (antecedent-consequent pairs of such conjunctive forms): these concepts and behavior rules are inferred from sequentially presented pairs of examples by an algorithm that is probably…

The training requirements analysis model (TRAMOD) described in this report represents an important portion of the larger effort called the Digital Avionics Information System (DAIS) Life Cycle Cost (LCC) Study. TRAMOD is the second of three models that comprise an LCC impact modeling system for use in the early stages of system development. As…

A procedure for using Guilford's structure of the intellect as the theoretical basis for a task analysis model is presented. It is reasoned that such a model would furnish a bridge between task analysis and test selection, and also a bridge between test selection and test validation. Such a mechanism might answer some of the Equal Employment…

This paper reports a project where school guidance staff themselves develop and use instrumentation in order to measure derived behavioral objectives. The task analysis is to provide objective data on the actual use of counselor's time; allow comparison between counselors; provide objective data upon which can be based improvement and change…

This paper analyzes a typical school spelling task in terms of an information processing model of spelling performance. Based on principles embodied in a computer simulation program previously reported (SPEL by Simon and Simon) the model proposed here has been expanded to try to account for many more kinds of student error than were possible with…
