The general objective of a research program on adaptive testing was to identify several sources of potential error in test scores, and to study adaptive testing as a means for reducing these errors. Errors can result from the mismatch of item difficulty to the individual's ability; the psychological effects of testing and the test environment; the…

To what degree testing can become adaptive is considered in three ways: from a formal methodological perspective; from a human process, stability, perspective; and from a sub-system or component view within an adaptive instructional system (AIS). With the advent of large computer-based training systems, the opportunity to broadly implement…

An investigation was conducted to determine whether the Parental Attitude and Behavior Inventory (PABI) Form III, a lengthy self-report instrument (577 items each for both parents) for assessing parents' attitudes and behavior toward their children and each other, could be shortened to a more feasible length. This terminal report summarizes the…

Gives examples of major sources of unreliability in multiple choice items in health professions classroom achievement tests (clues to response combinations, mutually exclusive alternatives, implausible distractors) and offers some suggestions for eliminating them when writing such tests. (MF)

A study was undertaken to improve the measurement of small team performance within the Army. A provisional taxonomy of team-level performance functions was field-validated; criteria and measures of the functions were developed; and their reliability was examined. The provisional taxonomy, used for observing Army field training exercises, was used…

Latent trait theory supposes that, in testing situations, examinee performance on a test can be predicted (or explained) by defining examinee characteristics, referred to as traits, estimating scores for examinees on these traits and using the scores to predict or explain test performance (Lord and Novick, 1968). In view of the breakthroughs in…

Four forms of a 36-item adaptation of the Stanford Achievement Test were administered to 484 fourth graders. External factors potentially influencing test performance were examined, namely: (1) item order (easy-to-difficult vs. uniform); (2) response location (left column vs. right column); (3) handedness which may interact with response location;…

Faculty from fifteen colleges developed open-ended questions to assess group competence in four areas of learning associated with general education--communication skill, analytic thinking, synthesizing ability, and social/cultural awareness. A secondary purpose was to determine faculty expectations for learning in the general education component…

The 168 items selected for administration to 7,905 17-year olds in 1976-77, were developed from existing National Assessment items and from existing sets of life/coping skills. Skills designated as basic included: career development; citizenship; community resource utilization; consumer protection; family management; health maintenance; and…

The principal objectives of this conference were to exchange information, discuss theoretical and empirical developments, and to coordinate research efforts. The papers and their authors are: "The Graded Response Model of Latent Trait Theory and Tailored Testing" by Fumiko Samejima; (Incomplete Orders and Computerized Testing" by…

This report presents a thematic summary of the AERA papers dealing with test development, interpretation, and use, presented at the 1971 meeting in New York City. Papers were grouped into the following categories: test development and validation; inventory development and validation; measurement of creativity; factors in test performance; use of…

Investigations into item bias provide an empirical basis for the identification and elimination of test items which appear to measure different traits across populations or cultural groups. The Psychometric rationales for six approaches to the identification of biased test items are reviewed: (1) Transformed item difficulties: within-group…

To assess the impact of various rating scale formats in rating student teachers, a Likert-type scale (Highly agree/slightly agree/neither/slightly disagree/highly disagree) was derived from the graphic scale currently used by the cooperating teachers and university supervisors. They rated the music student teachers on an eight-point scale from…

The technical implementation and operation of the Comprehensive Achievement Monitoring (CAM) system are discussed in this manual. It is written as a guide for those responsible for implementing CAM and for processing CAM-related work requests. Subjects covered include: CAM system operation summary: objectives and test items; conferencing with the…

Three and one-half years of research on computerized ability testing are summarized. The original objectives of the research were: (1) to develop and implement the stratified computer-based ability test; (2) to compare, on psychometric criteria, the various approaches to computer-based ability testing, including the stratified computerized test,…
