The use of the two-stage least squares (2 SLS) procedure for estimating nonrecursive social science models is often impractical when multiple feedback linkages are required. This is because 2 SLS is extremely sensitive to multicollinearity. The standard statistical solution to the multicollinearity problem is a biased, variance reduced procedure…

Recognition of new demands in Swedish education during the 1960s led to selection of eight principles to be considered in educational facilities planning. These principles concerned (1) freedom of students to change schools, (2) availability of school space for nonschool functions, (3) flexible use of spaces for varied student activities, (4)…

Because of states' growing roles in education, the study of variation in state educational policies contributes to a better understanding of policy processes and to the prediction of possible policy outcomes. Comparing state educational policies involves choosing variables and analytical designs and defining cases, concepts, and measurement.…

This paper reports the progress of an ongoing clinical research project on prevention services for at risk infants of mentally ill mothers. This project extends the prevention focus of early education programs into the mental health field. Previous research findings indicate that maximum preventive effects are achieved when programs (a) begin…

Psychological studies on personality characteristics obtained from individuals prior to being diagnosed as alcoholics are reviewed. Retrospective studies suggesting an association between childhood anti-social behavior and the subsequent problem of alcoholism are presented, supported by studies of the personality inventories of college students…

Provided is an examination of the methodology used to study the problems of learning addition and subtraction skills used by developmental researchers. The report has sections on categories of theory and their methodologies, which review: (1) Behaviorist, Neo-Behaviorist and Piagetian Theories; (2) the Behaviorist and Piagetian Paradigms; (3)…

Empiricists may be defined as naive fumblers, people who collect and analyze data in the absence of a guiding theory. A theory may be defined as an empirically verifiable explanation of phenomena that predicts behavior. Empirical research may be defined as scholarship that is public and is performed using entities measured in units that can be…

Problems and procedures in assessing and obtaining fit of data to the Rasch model are treated and assumptions embodied in the Rasch model are made explicit. It is concluded that statistical tests are needed which are sensitive to deviations so that more than one item parameter would be needed for each item, and more than one person parameter would…

This document contains reports examining research designs for Educational Resources Information Center (ERIC) usage studies at three levels: (1) system operations; (2) subscribers to the services provided; and (3) the ultimate "end-users" of the service. The first level report, which addresses ERIC as an information network, proposes two…

A two-phase investigation of characteristics associated with student achievement in elementary and secondary reading centers in the Houston (Texas) Independent School District is described and evaluated in this paper. After presenting background information about the centers, the paper describes the first phase of the investigation, which revealed…

Interactive Research and Development on Teaching (IR&DT) was initially proposed as an alternative to linear educational research and development strategies that often resulted in irrelevant, uninterpretable, time consuming research that did not actively involve teachers. This paper reports on the insights gained from implementing the IR&DT…

THE PURPOSE OF THIS STUDY WAS TO EXAMINE THE PROFUSION OF LOCAL AND REGIONAL MANPOWER STUDIES SO COMMUNITIES SEEKING TO UNDERTAKE MANPOWER STUDIES COULD LEARN FROM THE EXPERIENCE OF OTHERS. OVER 300 MANPOWER STUDIES WERE EXAMINED AND CLASSIFIED AS -- (1) MANPOWER REQUIREMENT SURVEYS, (2) POTENTIAL LABOR FORCE SURVEYS, (3) WAGE SURVEYS, (4)…

THE THEORETICAL ORIENTATION OF THIS PAPER IS TOWARD STIMULUS RESPONSE (S-R) LEARNING THEORY, WITH EMPHASIS ON THE POLLARD-MILLER PARADIGM OF (1) DRIVE, (2) CUE, (3) RESPONSE, AND (4) REWARD. IN THE CONSTRUCTION AND UTILIZATION OF MEDIA AND TEACHING MATERIALS, THESE FOUR CONDITIONS REQUIRE THE EMPLOYMENT OF A NUMBER OF INSTRUCTIONAL VARIABLES. THIS…

Although predictive validation is the primary method of justifying a particular work sample for use as an assessment device, content validation is being recognized as an alternative strategy. Confusion exists over whether content validity should refer to the representativeness of the work sample, in terms of tasks to be performed, or behavioral…

This paper (1) examines some of the problems confronting persons doing research on adult educators; (2) presents a conceptual framework for clarifying researchable relationships among several selected major variables; and (3) suggests directions and approaches that appear promisinq to the authors. The first of three parts contains a brief…
