With an emphasis on the problems of control of extraneous variables and threats to internal and external validity, the arrangement or design of experiments is discussed. The purpose of experimentation in an educational institution, and the principles governing true experimentation (randomization, replication, and control) are presented, as are…

This document describes an educational experiment designed to test the proposition that language learning can best be carried on through a program of maximum exposure in the least possible time. An experimental class of 19 average students participated in an eight-week intensive course consisting of four half-hour laboratory sessions; there were…

The purpose of an 8-week summer training institute was to provide 25 competent professional school personnel the necessary methodological skills to initiate, conduct, and report experiments on school learning and instruction. All trainees held administrative posts with responsibilities for curriculum research and development and/or instruction. A…

This study is a followup conducted 1 year after the 1966 study (ED 001 162) which attempted to assess the effects of reduced loads and inservice help on the classroom behavior of 120 beginning teachers. A conclusion of the original study was that the experimental group showed at least 25% higher scores on teaching performances than the control…

Different effects of instructional strategies on recall and comprehension of terms frequently used in formal analysis of art were examined. The study looked at a synthesis of three theoretical positions: dual-coding theory, schema theory, and elaboration theory. Two-hundred and fifty sixth-grade students were randomly assigned to three groups:…

The technique originating from the study of ecological systems for the examination of dynamic educational systems over time is utilized. The technique is based on the theory of energy exchanges in interactions between variables. Using this technique, interactions among variables can be specified and simulated over time using an analog computer.…

The primary purpose of this experiment is to determine the effect of reading development based on phonemic transcription and traditional orthography on the pronunciation of French as a second language. Sixteen level 1 French classes in Western New York State schools participated in the experiment in which the control and experimental classes…

This study continues an earlier project (ED010369) to determine if student achievement and attitude toward school subjects (1) can be improved by increasing feedback to teachers concerning pupil and/or trained observer reaction to their teaching, (2) correlate significantly with attitude of teachers toward their pupils, (3) can be improved to a…

This report describes the experimental design, presents the contract provisions, and provides conclusions and recommendations. The document is comprised of five chapters that discuss (1) the statistical analysis methods used, (2) the problems of using standardized tests in performance contracting, (3) the contractual procedures between OEO and the…

The major portion of this report reviews a recent study that replicated and extended earlier research by Schalock, Beaird, and Simmons (1964, ED 003 620) on the use of situation reaction tests (using motion picture representations of classroom situations as test stimuli) to predict teaching behavior in the classroom. Chapters I and II summarize…

THE PRIMARY PURPOSE OF THIS EXPERIMENT WAS TO DETERMINE WHETHER HIERARCHICALLY DIFFERENTIATED GROUPS WERE AS PRODUCTIVE ON PROBLEM-SOLVING TASKS AS HIERARCHICALLY UNDIFFERENTIATED GROUPS. THE EXPERIMENT ALSO INVESTIGATED THE EFFECTS OF FORMALLY BASED STATUS DIFFERENCES ON GROUP EFFICIENCY AND RISK-TAKING. TWENTY GROUPS CONTAINING FOUR SUBJECTS…

This document presents four correlated studies based on (1) the concept of "micro-criteria" which narrows the dimensions of investigating teacher effectiveness through the variable (explaining), the potential correlates (classroom behavior), and the rating of effectiveness (pupil achievement) and (2) data from an initial experiment in…

A model of the inquiry process based on John Dewey's concept of inquiry was used to develop a means of observing and scoring individual inquiry behavior. The Teacher's Inbasket, a simulation of problems crossing a teacher's desk in a simulated school setting, was developed for the study. Fifty-one female elementary education majors were selected…

Reviews empirical education research trends in West Germany since 1965. Reports on the movement from normative research to empirical research in educational settings. Considers research priorities and the primacy of the University of Constance (West Germany) in developments focusing on analyzing the factual order of the educational system rather…
