Members of a Teachers Center used research literature to generate ideas for a classroom activity, then did the activity in order to test it. The activity described here involved hypothesizing rules defining sequences of three numbers. (SD)

This article discusses various approaches to linguistics, the basic distinction being that between the scientific descriptive and the introspective speculative approach. The latter is excluded as not part of true fundamental linguistics. A discussion follows on the concept of linguistic theory and description as pertaining to the functionalist…

Recent case studies of social effects of rapid community growth associated with energy development in the western states have relied primarily on qualitative data with limited use of agency records, population surveys, and other secondary sources. While providing the first essential step in the orderly development of a scientific approach to…

Based on the theory that a story's coherence depends directly on the causal cohesiveness of the story's individual events, this paper describes (1) a process by which readers use causal reasoning to connect events, (2) what memory representations result from this reasoning, and (3) the implications of test data on causal reasoning. Following a…

The schema theory of comprehension as it relates to understanding while reading is reviewed in this report. Several techniques for the study of on-line measurement of comprehension are described that are based on a series of ten stories, each with two versions. The report notes that when subjects were asked to generate interpretations of stories…

The objective of this paper is to examine the relationship between the unreliability of difference scores and the power of tests of significance in an attempt to determine the validity of the paradox for the measurement of change presented by Overall and Woodward: that the power of tests of significance is maximum when the reliability of the…

Path analysis is presented as a technique that can be used to test on a priori model based on a theoretical conceptualization involving a network of selected variables. This being an introductory source, no previous knowledge of path analysis is assumed, although some understanding of the fundamentals of multiple regression analysis might be…

A solution is proposed for analysis of variance procedures with missing cells, such as may occur when a control group is not assigned to any of the rows or columns of the various experimental groups. Mathematical models for two-way design are presented which define several variables; as well as row effect, column effect, and row and column…

THE STUDY DEMONSTRATED THAT THE RATIO OF UNSKILLED TO SKILLED EMPLOYMENT AND UNEMPLOYMENT VARIES FROM THE PEAK TO THE TROUGH OF THE BUSINESS CYCLE. DATA PRIMARILY FROM "EMPLOYMENT AND EARNINGS AND MONTHLY REPORT ON THE LABOR FORCE," MARCH 1967 WERE USED IN RELATING THE ANNUAL UNEMPLOYMENT RATES FOR CRAFTSMEN AND LABORERS TO BUSINESS CYCLE PEAKS…

AN ATTEMPT IS MADE TO ESTABLISH A THEORETICAL FOUNDATION FOR GROUP PROPERTY AND LIABILITY INSURANCE AND TO ADVANCE THE GENERAL HYPOTHESIS THAT THE PRINCIPLES USED IN INSTALLING AND ADMINISTERING GROUP LIFE AND HEALTH INSURANCE ARE APPLICABLE TO THE INSTALLATION AND ADMINISTRATION OF GROUP PROPERTY AND LIABILITY INSURANCE. A SURVEY WAS CONDUCTED TO…

THREE STRUCTURED Q SORTS CONTAINING LIBERAL, CONSERVATIVE, PROGRESSIVE, AND TRADITIONALIST STATEMENTS ENABLED THE INVESTIGATOR TO TEST THE HYPOTHESIS THAT INDIVIDUALS WHO ARE LIBERAL IN THEIR SOCIAL ATTITUDES WILL TEND TO BE PROGRESSIVE IN THEIR EDUCATIONAL ATTITUDES, WHEREAS INDIVIDUALS WHO ARE CONSERVATIVE IN THEIR SOCIAL ATTITUDES WILL TEND TO…

Provided are hypotheses and evaluation forms to evaluate vocational-occupational-technical education (V.O.T.E.) programs whose purposes include the mainstreaming of handicapped students. Materials are geared toward testing the following five hypotheses: most occupational administrators can cite specific examples of formal or informal evaluations…

The testing of a priori contrasts, post hoc contrasts, and experimental error rates are discussed. Methods for controlling the experimental error rate for a set of a priori contrasts tested simultaneously have been developed by Dunnett, Dunn, Sidak, and Krishnaiah. Each of these methods is discussed and contrasted as to applicability, power, and…

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…

The Chi-Square Test for Hierarchical Dependency (THD) is presented. The THD tests the hypothesis that all members of a population who possess a certain skill are a subset of the members who possess another skill. This hypothesis is basic to the writings of several prominent theorists, such as Gagne and Piaget. The THD is designed as an improvement…
