The jackknife is a general inferential technique intended to ameliorate the problems associated with inadequate sampling theory. The research reported herein is directed at investigating the utility of the jackknife for establishing confidence intervals on and testing hypotheses about the disattenuated correlation coefficient for small samples. A…

This report presents the results of research that examined widely diverse decision problems and attempted to specify their common behavior elements. To take into account the psychological complexity of most real-life decision problems, and to develop a tentative organization of decision behavior that will embrace the many, highly diverse types of…

Texts often suggest running preliminary tests for homogeneity of variance prior to running an ANOVA. While it has been known for some time that most of the suggested tests are probably not appropriate, they are still being used. This paper is a review of the literature in terms of the implications involved in running preliminary tests in general…

The author reviews the literature about the effects of commuting on students. Commuting students tend to perceive and experience higher education differently than resident students. Educational planning, which tries to increase contact with faculty members and student peers, has been found to help commuting students. (SE)

Cites the advantages of studying the group process through the historical example and notes specific principles that students can draw from these models to apply to their own discussion groups. (MH)

Explored the relationship between knowing how to think and teaching students to think. The findings indicated that development of pupil's intellectual capacities depend on an adequate assimilation of general methods of thinking and that psychology, logic, and pedagogy can today provide the teacher with the technical resources necessary to make…

The old empirical-rational and power-coercive system of policy development and implementation is inappropriate in our pluralistic environment. The problem-solving strategy combines rationality, involvement, flexibility, and decentralization. It has new implications for administrators' roles. (Author/SJL)

The conversion model of formal reasoning was examined for its ability to predict the decisions made by college students when solving concrete and abstract syllogisms. Results supported the model's contentions that reasoner's decisions reflect natural language processes in the encoding of syllogistic premises, and follow rationally from…

Planning the menu for a dinner party, which involves problem-solving with a large body of knowledge, is used to study the daily operation of human memory. Verbal protocol analysis, a technique devised to investigate formal problem-solving, is examined theoretically and adapted for analysis of this task. (Author/MV)

Examines various influences on the dominant paradigm that ruled intellectual definitions of development through the late 1960's. Chronicles the emergence of a newer conception of development which implies a different role for communication than the usual top-down development approach of the past. (MH)

Criticizes a discussion of the reformation of post-TUCE learning equations by John Soper, which were presented in an earlier issue (see EJ 152 358). Claims that the author's manipulations from one equation to another essentially repackaged the same information. (Author/DB)

Various educational practices resulting from research recommendations and the associated problems are described. The author suggests that educational research can create a more reliable foundation for policy decisions concerning the introduction of reforms, by evaluating their resulting effectiveness. Investigators should suggest more pertinent…

This article outlines a data collection model designed by Riffel and associates. This model provides information which may assist district and school level personnel in facilitating the desegregation process. (Author/AM)

The water jug task model was extended to four variations of the Missionaries--Cannibals river-crossing problem. Different cover stories resulted in large differences in number of illegal moves, but no difference in number of legal moves to solution. The three-stage process model explains both legal and illegal moves. (Author/GDC)

Depression is an emotional dysfunction encountered daily by counselors. This author discusses a step by step behavioral paradigm developed specifically to be employed with moderately depressed persons not receiving sufficient positive reinforcement from their environment. (Author/MPJ)
