This report is one of five submitted as products of a "Study Designed to Assist Planning of Research on Significant Instructional Features in Bilingual Education Programs." The reports are intended to assist the National Institute of Education (NIE) in its plans for a major new research study in bilingual education. The present report is…

A meta-analysis of 29 separate studies investigating pretest effects was conducted. Outcomes of the studies (achievement gains or attitude improvements) were computed as standardized differences between pretested and non-pretested groups. Eleven other variables were coded for each outcome. Initial descriptive statistics were indicative of…

Corporate advocacy is the study and practice of communication efforts to advance the policies of business, education, governmental, and nonprofit institutions. The functions of the advocate include gathering information, providing advice based on the information, conducting advocacy programing, and evaluating results. Advocacy research is…

Research on linkages between teacher behavior and student learning is examined. Present and possible future process-outcome research is assessed with an emphasis on methodological considerations. Compilation of detailed normative data about classrooms, including explication and integration of process-process as well as process-outcome…

A procedure was developed within hypothesis-testing logic that allows researchers to support a hypothesis that has traditionally been the statistical or null hypothesis. Four activities involved in attainment of this goal were discussed: (1) development of statistical logic needed to define the sampling distribution associated with the hypothesis…

Methods for ordering and selecting variables for discriminant analysis in multiple group comparison or group prediction studies include: univariate Fs, stepwise analysis, learning discriminant function (LDF) variable correlations, communalities, LDF standardized coefficients, and weighted standardized coefficients. Five indices based on distance,…

The Comparative Systems Laboratory (CSL) proposed to deal with the problem of testing retrieval systems by examining a number of processes involved in such systems, with particular attention to the human factor. It is hoped that the results of the project will be useful in refining methodologies for experimentation with information retrieval (IR)…

The feasibility of an educational park for a school district in Arkansas is examined. A brief introduction defines the educational park idea and sketches its background. Advantages and disadvantages are cited as are the evaluative criteria employed. The research design and its results are stated, and the phases of the proposed development…

The objective of this project was to investigate the adequacy of statistical models developed by G. E. P. Box and G. C. Tiao for the analysis of time-series quasi-experiments: (1) The basic model developed by Box and Tiao is applied to actual time-series experiment data from two separate experiments, one in psychology and one in educational…

This document reports on a planning conference of the International Mathematics Committee, responsible for the second study of school mathematics to be conducted by the International Association for the Evaluation of Educational Achievement (IEA). The study will address issues of interest to mathematics educators, with emphasis on the areas of…

This working paper presents specifications for the test items to be used in the second mathematics study to be conducted by the International Association for the Evaluation of Educational Achievement (IEA). A content-by-behaviors grid is presented for two population levels, with specifics for each dimension outlines and examples of test items…

The purposes of this paper are to examine more intensively than was attempted in the authors' first paper (not available through ERIC) a subset of the parent-child studies published in Child Development and Journal of Marriage and the Family for evidence of qualitative differences in the methodological approaches used in the two journals, and to…

The Springs Task measures the ability to conduct controlled experiments, name variables, and criticize variables which are demonstrated to the subject. It provides an operational definition of formal thought. Subjects aged ten to adult can be tested with this instrument, an apparatus-based task administered individually in a 15-minute interview.…

In recent years data have begun to accumulate on the efficacy of role playing as an alternative to deception in research. The ethics of deception as a research technique are also being considered. The present study was designed to provide data describing subjects' post-participation attitudes toward research and researchers in comparable role…

Institutional research (IR) in community/junior colleges in past years has been limited to gathering data for external agencies, concentrating on raw demographic data and student flow studies. IR should be directed toward providing data for administrative decisions and for successful maintenance of college operations. In spite of the heavy demands…
