The methodological issue of qualitative versus quantitative research is addressed, and the argumentation of research using interview methods for research is explored. Warrants of the type that are used in arguments generating conclusions from interview data are included. (KR)

In a continuing description of a Head Start longitudinal study, analyses are presented of the interrelationships among individual measures of the child's performances prior to school entry, accompanied by brief descriptions of the tasks and the scores used. Despite the size and extensiveness of the data base, the findings are considered tentative…

In the current paper we describe the methodology and results of the Oswego study, in light of D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow's (this issue) criticisms regarding the validity of the human health/behavioral claims in the PCB literature. The Oswego project began as a replication of the Lake Michigan Maternal Infant Cohort study.…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

A study was undertaken to develop an evaluation procedure that could be used to analyze the cognitive requirements of instructional materials used to teach beginning reading. The study involved four phases. The first phase, an examination of the literature in order to create a basis for the development of assessment procedures, included an…

This document is an update of Focus on Research: A Guide to Developing Students' Research Skills (Alberta Education, 1990). Focus on Research was developed in response to suggestions from Alberta teachers during the implementation of Focus on Learning: an Integrated Program Model for Alberta School Libraries (Alberta Education, 1985). …

More carefully controlled research distinguishing more facets which may influence cognitive and social performance in young children is considered necessary before Head Start or any preschool program can be adequately assessed. Shortcomings in evaluation methodology discussed are as follows: evaluation research has not addressed itself to program…

This educational research project is designed to assess an elementary student's quality of reasoning in relation to map skills and to determine spatial concept abilities. 21 activities are designed to test sense of proportion, scale, dimension, accurate relationship, and abstract thinking. The related topographical map, a Map-Study Scoring Key,…

This document contains abstracts of papers presented during the 93 sessions of the 1969 annual meeting of the American Educational Research Association. The papers use a wide variety of research approaches and techniques to investigate such topics as teacher characteristics and behavior, the learning process in various settings, curriculum…

Measuring cognitive achievement gains in project evaluation is dealt with. This guide provides those concerned with project evaluation with the basic tools for conducting technically sound, interpretable evaluation studies. Exotic designs are avoided and five basic models which appear feasible to implement in real-world settings are focused on.…

This study identified behaviors of sibling pairs interacting on a cognitive task and related these behaviors to sibling structure variables (age and sex of each sibling and age spacing between them) and to measure of cognitive abilities of the younger sibling. Subjects were 160 sibling pairs randomly selected from appropriate subpopulations of…
