Examines critically the viewpoint that the reason why some black students do well in school while other black students do poorly depends on the quality of the student's family life. Considers the major assumptions of this argument, as well as its ideological significance. (Author/RK)

Develops a theory of mediated learning from practice. Problems inherent in developing theories are reviewed; general assumptions are identified; and a descriptive theory is generated that identifies favorable factors facilitating learning. Factors are checked for consistency and used to generate hypotheses for collecting research data capable of…

The slower progress of semantic memory research is attributed to the difficulties involved in testing the relevant theories. This paper proposes a model for testing such theories using the Continuous Response (CR) task. The model establishes a link between the rate of recall and the semantic relationships among the category items. (JAZ)

Describes study that investigated the communicability of the emotional connotation of various typefaces. Typographers, student instructional technologists, and naive readers (high school and college students) rated 30 typefaces using a semantic differential scale. Seven hypotheses tested are discussed and results are analyzed. (Author/LRW)

This study evaluated 16 hypotheses concerning possible sources of bias in test items on the Graduate Record Examination General Test. Ten of the hypotheses showed interactions between group membership and the item version indicating a differential effect of the item manipulation on the performance of Black and White examinees. (Author/LMO)

This study examined whether reference questions based on the text-linguistic structure of scientific literature would enable users to express their information needs effectively. Subjects with similar levels of topic familiarity completed online search forms that used open, bibliographic, or (text-linguistic) structural questions. Questions based…

Describes a study that used a staff development program on computer technology to examine computer anxiety and other factors related to resistance to computers among library personnel. The discussion covers determinants of computer anxiety that were identified and the effects of anxiety on workshop participation. (16 notes with references)…

The efficacy of an educational intervention in teaching medical students to select optimal diagnostic data consistent with the competing-hypotheses heuristic and Bayes' theorem when solving clinical problems was examined. The results suggest that some problem-solving skills can be enhanced or learned independent of the acquisition of content…

Olson's Circumplex Model hypothesizes that cohesiveness and adaptability dimensions measured on Family Adaptability and Cohesion Evaluation Scales (FACES) have a curvilinear relationship with family functioning. Study testing curvilinear hypothesis indicated that FACES II and III did not adequately operationalize curvilinear hypothesis. Findings…

The role of biological maturity in behaviors in adolescents which most often are considered as negative by adults was investigated for a normal group of girls. (Author/LMO)

Tested the hypothesis that increasing library services would increase returns of a questionnaire generated by that library. Students and faculty were surveyed before and after new services were offered at Wharton School. Results suggest source of sponsorship should be related to user group to be surveyed to maximize return rate. (CDD)

Describes a citation analysis of physics, engineering, and sociology literature which was designed to determine if there were any differences in conceptual referencing patterns. The research methodology is described and suggestions for further study are offered. (Author/LRW)

This paper investigates three methods for comparing medians rather than means in studying two independent treatment groups. The method that gave the best results is based on a normal approximation of the distribution of the sample median where the variance is estimated using results reported by Maritz and Jarrett. (Author/JAZ)

The purpose of the current study was to investigate the relative performance of the parametric, rank, and normal scores procedures when the classical assumptions were met and under violations of these assumptions. This investigation included the normal scores as well as the rank test. (LMO)

Suggests a method of integrating user performance and attitudes toward the computer system into quality control procedures (QCP) and describes an application of user attitudes to the QPC in a class of novice computer users receiving instruction in BASIC programing language via formal classroom lecture with computer assisted instruction tutorials.…
