Eighty-one randomly selected cotton producers in Lauderdale County were interviewed for the purposes of: (1) characterizing those in different cotton yield groups, (2) determining which practices were being used by those in different yield groups, and (3) identifying some of the factors influencing the farmers to use or not to use the 12 practices…

Four problems of data summary and analysis in the Concept Attainment Abilities Project are discussed. The problems are: (1) scoring and item analysis for items that exist in a completely crossed design; (2) determining the factorial structure of such item sets; (3) reducing the battery of 56 cognitive abilities tests administered in 1970 to…

The final volume of The Study of Junior Colleges contains the measurements and instrumentation derived from the project for future evaluation surveys. Part One, Prediction of Student Outcomes: Multivariate Analysis of the Survey Data, provides: an introduction to the analyses; data reduction, factors, and scales; students' objectives and…

In measuring attitudes by Semantic Differential, bipolar adjective scales with high loadings on an evaluative factor derived by Principal Components Analysis are used typically as unidimensional attitude measures. Komorita and Bass, using conventional statistical techniques, report the discovery of more than one evaluative factor. This paper…

This paper emphasizes the need for empirical research and objective discovery procedures in semantics, and illustrates a method by which these goals may be obtained. The aim of the methodology described is to provide a description of the internal structure of a semantic field by eliciting the description--in an objective, standardized manner--from…

The present study attempted to identify and describe individual differences in concept learning. It was hypothesized that if a significant portion of the reliable individual variation in a complex learning situation could be identified and described, it would be reasonable to expect that subsequent predictions could be made about the conditions…

Three approaches used in the analysis of semantic differential data to determine similarity in meaning between profile ratings on concept pairs are discussed. These approaches are: (1) to compute mean scores on each scale for each concept and to compare concepts on a scale-by-scale basis; (2) to form mean scores on each dimension for each concept…

This document reports on the advancement of an instrument for assessing the elementary school educational environment of young children. Fifty-four public elementary schools (K-6) in Massachusetts were randomly selected. Educational environment was assessed in the sampled schools by having 5,412 fifth and sixth grade students respond to two forms…

Gibb (1964) defined test-wiseness (TW) as the ability to respond advantageously to item clues in a multiple-choice setting and therefore to obtain credit without knowledge of the subject matter being tested. This study investigated TW in a sample of 6th grade pupils. A test instrument was developed utilizing fictitious material similar to the…

This document gives a detailed report of the advancement of an instrument for assessing the elementary school educational environment of young children. Fifty-four public elementary schools (grades K-6) in Massachusetts were randomly selected. Educational environment was assessed in the sampled schools by having 5,412 fifth- and sixth-grade…

AN INVESTIGATION WAS MADE OF THE ARTICULATION GAP WHICH RESULTS FROM THE LACK OF COMMUNICATION IN CHEMISTRY EDUCATION BETWEEN HIGH SCHOOL TEACHERS AND COLLEGE INSTRUCTORS OF FIRST-YEAR COURSES, AND FROM A LACK OF AGREEMENT ABOUT THE AIMS AND OBJECTIVES OF CHEMISTRY COURSES AT THE SECONDARY LEVEL. ELIMINATION OF THIS GAP WAS CONSIDERED BY THE…

FACTORS AMONG COLLEGE SENIORS WHICH INFLUENCE THE CHOICE OF COLLEGE TEACHING AS A VOCATION WERE STUDIED. DATA WERE GATHERED FROM 94 GRADUATE STUDENTS WHO WERE AWARDED DANFORTH GRADUATE FELLOWSHIPS IN THEIR SENIOR YEARS. AN EXPLANATORY LETTER, A SIX-PAGE QUESTIONNAIRE, AND THE STRONG VOCATIONAL INTEREST BLANK WERE MAILED TO THE SUBJECTS. IT WAS…

The results of a series of factor analyses of a new test of literal comprehension using a multiple-choice cloze format are summarized. These analyses were conducted in the validation of a test design to measure for the most part a factor of literal comprehension independent of IQ and inferential reading processes, yet marked by certain related…

This research tested the proposition that self-concept is unidimensional. Joreskog's Unrestricted Maximum Likelihood Factor Analysis applied to 402 fifth-graders' responses to the Sears Self-Concept Inventory, indicated a twelve factor pattern adequately accounted for variance. Restricted Maximum Likelihood Factor Analysis was than applied to…

Measures of active sleep, quiet sleep, sucking, crying, body size and gestational age were factor analyzed for 137 normal newborns at 2 days of age. The results yielded 3 stable factors: reactivity-irritability, maturity, and reflexive and discriminative sucking. (JMB)
