A qualitative case study examined professor and student perceptions regarding how professors use communication to build their classroom credibility and the influence of the professor's race in the establishment of credibility. The research design reflects the vantage point of an African-American female researcher acknowledging and incorporating…

As part of a large-scale project to remodel the Scholastic Aptitude Test (SAT), this study examined the predictive validity of a prototype revised SAT, which incorporated many of the important structural changes planned for the test. This prototype was compared to a form of the current SAT with regard to several validity-related issues. Nineteen…

This paper presents findings of a study that developed, measured, and tested the Organizational/Supervisory (O/S) Model of Instructional Supervision. The six dimensions of the Organizational Supervisory Climate Inventory (OSCI)--organizational structure, professional autonomy, collaborative sharing, district supervisory climate, reflection, and…

Among the more recent personality assessment tools used by counseling psychologists is Millon's Clinical Multiaxial Inventory (MCMI). This instrument was created, in part, to reflect the changes that had occurred in psychologists' understanding of personality, psychopathology, and diagnostic assessment. The MCMI is derived from Millon's biosocial…

A scale was developed to assess several types of motivation in elementary school children. In addition to the usually recognized internal and external motivation, a third type, termed "amotivation," has been postulated. Students are amotivated when they do not perceive a link between outcomes and their own actions. The preliminary…

It is not surprising that a broad array of treatment programs have been developed to reduce test anxiety, since the consequences can be serious. The contributions in this volume review and evaluate the theory of test anxiety, its measurement, its manifestations, and possible treatments and their outcomes. The following chapters are included: (1)…

Student ratings of instruction are widely used as a basis for personnel decisions and faculty development recommendations. This digest discusses concerns about the validity of student ratings and presents a case for their use in teacher evaluation. There are several strong arguments for using student ratings to evaluate teachers. Students are in a…

The accuracy of procedures that are used to compare the performance of different groups of examinees on test items obviously depends on the correct classification of members in each examinee group. The significance of this dependence is determined by the sensitivity of the statistical procedure and the proportion of examinees who are unidentified.…

A recent unpublished study by B. Griesemer (1995) studied the relationship between motivation and self-efficacy for learning among 146 sixth graders. Griesemer used two instruments in that study: one to measure intrinsic versus extrinsic motivation composed of three subscales from the Scale of Intrinsic versus Extrinsic Orientation in the…

A study assessed the usability, retest reliability, and construct validity of an instrument measuring young adults': (1) perceived attention from parents; (2) perceived "normalcy" of family interactions; and (3) perceived consistency of family interactions. The retest reliability study yielded no significant differences between 73…

A mental model is a knowledge structure composed of concepts and the relations between them. Mental models are distinct from declarative and procedural knowledge--they go beyond semantic relationships and skills acquisition and contain varied intellectual skills and knowledge. This study describes an initial investigation into the construct…

The first study described in this paper estimates the reliability of the four subscale versions of the 40-item Computer Attitude Scale (CAS), an instrument designed to measure attitudes toward learning about and using computers. It provides detailed information about the factor patterns of CAS subscales and evidence of the differential validity of…

The present research developed and validated a self-reported instrument called the "Relaxing Others Scale" (ROS), which is designed to identify individuals who possess the ability to relax others. A second part of the study involved assessing the construct validity of the ROS. Participants in the study were male and female dormitory…

This article illustrates how a cluster analysis can be conducted, validated, and interpreted. Data normed for a behavioral assessment instrument with 14 scales on a nationally representative sample of U.S. school children were utilized. The discussion explores the similarity index, cluster method, cluster typology, cluster validity, cluster…

Conducting observational research in a cross-cultural context invokes a unique set of difficulties. This paper describes sources of bias and threats to validity that are specific to cross-cultural research. It describes problems of cross-cultural research designs for descriptive studies, comparative research, and experimental research and outlines…
