The aim of this study is to investigate the effects of an instructional intervention on enhancement the pre-service science teachers' (PSTs) science process skills (SPSs) and to identify problems in using SPSs through Laboratory Applications in Science Education-I course (LASE-I). One group pretest-posttest pre-experimental design was employed. An…

The aim of this paper is to study the analysis of contingency tables with one heavyweight column or one heavyweight entry by taxicab correspondence analysis (TCA). Given that the mathematics of TCA is simpler than the mathematics of correspondence analysis (CA), the influence of one heavyweight column on the outputs of TCA is studied explicitly…

Structural models that yield circumplex inequality patterns are reviewed, focusing on a model developed by T. W. Anderson (1960). A modification is proposed to this model to allow for negative correlations. This model may be reparameterized as a factor analysis model with nonlinear constraints on the factor loadings. (SLD)

A quantitative comparison of peer versus bibliometric procedures for rating the quality of U.S. universities is presented. The quality of graduate faculty is measured by the Roose-Andersen peer rating, while bibliometric ratings are based on the number, average "quality," and total influence of university papers in each field.…

Describes study of college students that was conducted to determine whether increasing the amount of data in different graphic formats affects the interpretation of quantitative information. Immediate and delayed recall are examined, and correlations between graphic format and field dependence and independence are discussed. (12 references) (LRW)

This technical project report provides the National Science Foundation with information regarding the substantive achievements of the Social Science Education Consortium's project QUESST (Quantitative Understanding To Enhance Social Science Teaching). The report begins with a discussion of materials development and project publicity. Thirty-three…

Utilizing 11 years of University of Saskatchewan circulation transactions, it is shown that P. M. Morse's Markov model of book use fits approximately 99 percent of data for whole collection and for three subject areas; contrary to his assumptions, one of the model's parameters is time dependent. Thirteen references are included. (EJS)

Describes a study to determine if time spent in modular instruction is related to improvement in performance on weekly tests or final examinations across four years in a course on plant anatomy taught by Self-Instructional Modules and Interactive small Group discussion (SIMIG). Twenty-one references are listed. (Author/CHC)

The use of a three-parameter logistic model for applying latent trait theory has become more popular because of the availability of computer programs. The program Logist 5 can be used not only for the item parameter estimation in the three-parameter logistic model, but also in the two parameter logistic model by setting the third parameter equal…

In order to explain the derivation and implications of the Association of Research Libraries (ARL) Library Index (a descriptive statistical indicator of research library quality which is based on an analysis of certain key library characteristics), this paper discusses regression and correlation as methods for measuring relations between such…

The purpose of this research was to look at the currency of the collection of a small public library and to determine the relationship between the amount of usage of the collection and the currency of publications in the collection. A 10% systematic sample was taken of the circulating nonfiction adult shelf list of the Franklin Public Library…

The Anchor Test Study provides a method for translating a pupil's score on any one of eight widely used standardized reading tests for Grades 4, 5, and 6 to a corresponding score on any of the other seven tests, as well as furnishing new nationally representative norms for each of the eight tests. In addition, the study presents new estimates of…
