The purpose of the present investigation is to study the hierarchical structure of academic self-concept. The original Shavelson model posited specific facets of academic self-concept to define a single higher-order facet, but Marsh and Shavelson (1985) found the hierarchical structure to be more complicated. In a revised model they proposed that…

When the three-parameter logistic model and item response theory are used to analyze Graduate Management Admission Test (GMAT) data, there are problems with the assumption of unidimensionality. Linear factor analytic models, exploratory factor analysis programs, and the comparison of item parameter estimates for heterogeneous and homogeneous…

The needs-press model, as operationalized by the Stern Activities Index (AI) and the Organizational Climate Index (OCI), was examined for its usefulness in evaluating and measuring organizational climate in a school setting. According to the model, needs represents personality and press represents the environment. This research was designed to…

This paper examines the development of the "Comfortability Scale in Special Education." This 44-item self-evaluation instrument measures special education teachers' perceptions of "comfort" (self-confidence) with their ability to use pertinent knowledge and skills. Each item is rated on a seven-point Likert-like scale. Two…

Confirmatory factor analysis (LISREL VI) is the method best suited to the comparison of measurement models when those models are based on a priori assumptions. Traditionally, positive and negative item stems were mixed on affective scales to reduce response set bias since the item pairs were considered to be parallel. Recent studies indicate that…

In both within-network and between-network analyses of the self, research results have indicated internal consistency, construct and discriminant validity in terms of multitrait-multimethod techniques, with discriminating weights for gender and age. Factor analyses have yielded a variety of clusters, including most often a self concept of ability.…

This study on barriers to online staff development for classroom teachers was conducted as part of the planning activities of a delivery models project designed to develop guidelines for implementing large-scale online staff development programs. The study involved engaging 54 general and special educators in several professional roles from nine…

Some evidence supports the hypothesis that formal operational reasoning ability (at least that measured by Piagetian tasks) is a unified process. The purpose of this research was to determine: (1) if conservation tasks, such as conservation of number, liquid amount, weight and volume, are unifactor; and (2) if conservation tasks form a scale of…

A live tailored achievement testing study was conducted to compare procedures based on the one- and three-parameter logistic models. Previous studies yielded inconclusive results because of the procedures by which item calibrations were linked and because of the item selection procedures. Using improved procedures, 83 college students were tested…

Attitudes toward school and three personality characteristics (introversion, impulsivity, and emotional stability) were measured in Swedish students from 60 sixth grade classes. The School and We Questionnaire (SAW) and a Swedish translation of the High School Personality Questionnaire were completed by 1,319 students. Secondary data analysis was…

The purpose of this study was to develop and assess the psychometric properties of a measure of teacher value systems. Three value systems were defined as values associated with (1) the pursuit of truth, (2) social and interpersonal relations, and (3) authority and its exercise. The scale was taken through three stages of development and field…

This paper reports on a new two-phase measurement technique that permits a direct comparison of the perceived relative importance of economic vs. non-economic factors in a job situation in accounting for personnel retention, the willingness to produce, and job satisfaction. The paired comparison method was used to measure the preferences of 91…

The following research projects are described in this annual report: (1) "Concept Learning in Discrimination Tasks," which indicates that kindergarten children are able to discriminate the letters "b,""d,""p," and "q"; (2) "Discrimination of Letter-like Forms," indicating that nursery…

The Addiction Research Center Inventory is a 550 item multipurpose test measuring the broad range of physical, emotive, cognitive, and subjective effects of drugs. This manual provides technical information concerning 38 most valid scales, a quantitative method for characterizing the similarity of a profile of scores for the subject, group, or…

In this study, the effects of motivational and behavioral dimensions of study behavior on objective and essay modes of evaluating course content were investigated. Several performance measures in two undergraduate Educational Psychology courses were factor analyzed, and three orthogonal performance factors were obtained: general achievement,…
