Contains four articles about various aspects of science education. Addresses a graded assessment scheme in Great Britain, factors affecting school science achievement in Nigeria, the need to address differentiation in science curricula, and the encouragement of developing science hypothesis in elementary schools.

Reviews study of 30 graduate students that investigated the possible contribution of pictures to the recall and retention of information presented in written prose. The two variables considered were the durability of picture effects, and the effect on recall of information that was not pictured. (LRW)

The central thesis of this article is that the process of eliminating validity threats depends fundamentally on no-difference findings, a fact that has not been made explicit by researchers. The implications of this neglect are explored using examples from a number of different substantive areas such as psychology, health, and medicine.…

Although "quality of education" issues are currently popular in educational evaluation, the author argues for an empirically resolvable evaluation paradigm: Given the target population, program goals, and boundary conditions, how do educational treatments compare in terms of learning effects? Agreement on pre-set specifications and the…

Two quasiexperimental designs--nonequivalent dependent variable and reversed treatment designs--illustrate pattern matching logic as a basis for evaluation, examining college health services. Three pattern matches are significant: (1) program pattern match indicates implementation; (2) measurement match assesses test validity; and (3) effect…

This paper presents 11 statistical procedures which test the equality of m coefficient alphas when the sample alpha coefficients are dependent. Several of the procedures are derived in detail, and numerical examples are given for two. (Author/LMO)

Results of investigation of M.L.S. degree students' needs for structure in required research methods course support hypothesis that, when exposed to such a course taught under low structure conditions, students with simple cognitive style would express demand for greater structure than would students with relatively complex cognitive style. (12…

The Lisrel-model with structured means was used to study similarities and differences in the development of mathematical ability between two student groups as measured by two tests on three successive occasions. Procedures for testing models to assess the contribution on an individual parameter to the goodness of fit are described. (Author/BS)

Discusses hypotheses which examine, for a nonprogramed decision, variables of (1) individual decision makers, (2) information upon which choices are based, and (3) structural features within which decision is made. Circumstances under which decision-making group (Ohio's librarians) selected an innovative alternative (incorporation of OCLC) are…

This study shows that a one-credit library research course designed around workbook/exercise module and bibliography assignment helps students learn library skills and results in improved attitude toward library. Pre/post tests were administered to experimental and control groups to assess skill and attitude level. Test and semantic differential…

Professional librarians were subjects for an exploratory study which used a model to test two hypotheses examining whether use of assertiveness by subordinates is associated with desired leader behavior. Findings suggest people's assertiveness is not related to their perception of their leader's behavior or their own role stress. (Sixty-three…

Presents results of two equivalent questionnaires distributed to college faculty and students to determine if faculty expectations of student library use differed from students' perceptions of their actual use; and if expectations and use were affected by college division, student class level, or class level taught.

National Board Certification is a voluntary process established by the National Board for Professional Teaching Standards (NBPTS) to measure what accomplished teachers should know and be able to do. Certification is achieved through a rigorous performance-based assessment that takes between one and three years to complete. As of November 2004,…

This book focuses on the relevance of statistics in the day-to-day lives of principals and teachers. The step-by-step guide to using existing school data can help school leaders make more appropriate and effective decisions. The information is presented with easy-to-follow instructions, illustrations, and pertinent examples. The chapters are: (1)…

Personal differences in teachers have a definite effect on the quality of education that students in inner city schools will receive. (CK)
