Discusses three phases of instructional design (ID)--definition of instructional parameters, analysis and synthesis of instructional alternatives, and implementation of instructional plan--and presents a 15-step ID model. Included for each step are a descriptive name, boxed example, and rationale and (as applicable) current state of technology for…

Cognitive activity of children from 1.5 to 5 years of age participating in problem solving and in spontaneous play was analyzed in terms of the successive coordination of existing patterns and the incorporation of new mental components. Analysis identified a series of developmental levels. (Author/RH)

This is the concluding part of an article published in the August 1983 edition. A number of arguments are developed to demonstrate the inadequacy of behaviorally defined objectives as a basis for curriculum planning. (SSH)

We present in this paper five case studies of instrumental genesis of number-theoretic concepts and techniques involving multiples, divisors, and numerical decomposition. The pupils, who were 12 to 15 years old, used the multi-line screen display of the graphing calculator to explore numerical tasks related to the "Five steps to zero"…

This paper summarizes the thinking of 84 middle school mathematics students' about variability in three stochastics tasks that involve repeated trial. Differences in students' acknowledgment of variability were found, depending on whether the task was from a sampling environment, or a probability environment. Students tended to neglect variability…

Considering a behaviorist's viewpoint focusing on specifics regarding learning and knowledge, this document discusses the psychology of learning and how it provides the reading/language arts teacher with a basis for making sound decisions in lesson and unit construction. It provides two examples of objectives for pupil achievement pertaining to…

Evidence-centered assessment design (ECD) is an approach to constructing educational assessments in terms of evidentiary arguments. This paper provides an introduction to the basic ideas of ECD, including some of the terminology and models that have been developed to implement the approach. In particular, it presents the high-level models of …

The present study is based on a form of task analysis that explicates in detail the hypothesized solution behavior of skilled performers of the task. (Authors)

Researchers suggest major changes in health care to spur efficiency and job mobility. (Editor)

An outline of 44 evaluator tasks is discussed in terms of its usefulness in defining, evaluating, and improving the position of "educational evaluator ; in adapting the position to the needs of particular institutions; and in designing appropriate evaluator training programs. (JES)

The task classification scheme suggests that motor skills be categorized as the processing demands placed on a learner, feedback availability, and pacing conditions. Potential learning strategies were identified and defined in relation to the classification scheme. (JN)

Recounts the use of the industrial engineering technique known as "operational audit" to determine the staffing needs of a U.S. Air Force technical library. The methodology and evaluative techniques employed during an operational audit are discussed. Two tables and a reference list accompany the text. (JL)
