Although over 15 years have passed since Witt (1990) noted that no empirical evidence exists to support the contention that a collaborative approach to consultation leads to more positive outcomes than a hierarchical or expert driven approach, this issue generally remains unaddressed (Schulte & Osborne, 2003). While the literature documenting…

The thesis of this paper is that systematic research approaches must be developed if the study of play is to avoid a short-lived "in" period before another 30-year hiatus, such as the one that occurred between 1940 and 1970. This paper reviews the present status of research on play, drawing examples from studies of the past 10 years that…

An experimental solar heating system heats five modular classrooms at the Fauquier County High School in Warrenton, Virginia. The present report covers the operation, maintenance, and modifications to the system over the 1974-75 and 1975-76 heating seasons. The solar system has shown the capability of providing essentially 100 percent of the…

This report covers a two-year and seven-month solar space heating and cooling experiment conducted at the Timonium Elementary School, Timonium, Maryland. The system was designed to provide a minimum of 50 percent of the energy required during the heating season and to determine the feasibility of using solar energy to power absorption-type…

This report documents the performance and conclusions of a 13-month period of monitoring the performance of the experimental solar heating and cooling system installed in the George A. Towns Elementary School, Atlanta, Georgia. The objectives of the project were to (1) make a significant contribution to solar design, technology, and acceptability;…

FROM 1962 TO 1963, THE JAPAN BROADCASTING CORP. CONDUCTED A STUDY TO MEASURE THE EFFECTS OF INSTRUCTIONAL TELEVISION ON PRIMARY SCHOOL CHILDREN IN ISOLATED AREAS OF JAPAN, WHO HAD SCORED BELOW THE NATIONAL AVERAGE ON NATIONWIDE ACHIEVEMENT TESTS. 4 PRIMARY SCHOOLS WERE CHOSEN FOR THE EXPERIMENT. THE STUDENTS WERE PRETESTED FOR INTELLIGENCE,…

TWO GRADE 9 MATH CLASSES (41 STUDENTS) OF LOW ABILITY WERE EACH EXPOSED TO LINEAR AND SELF-DIRECTED (COMPLETE FREEDOM AS TO EXTENT, SEQUENCE, AND METHOD OF STUDY) PROGRAMS ON SET THEORY AND PERMUTATIONS. ANALYSIS OF VARIANCE FOR ACHIEVEMENT TEST SCORES AND MEAN RETENTION SCORES SHOWED NO SIGNIFICANT EFFECT OF PROGRAM TYPE OF STUDY TIME.…

TO COMPARE CONVENTIONAL AND PROGRAMED INSTRUCTION ON TEACHING AUDITORY DISCRIMINATION OF THE "S" PHONEME, 20 LESSONS CONTAINING STIMULUS AND REPEAT ITEMS WERE RECORDED ON A COMMERCIAL MULTI- CHANNEL DEVICE THAT ALLOWS CONTINUOUS ADJUSTMENT ON THE BASIS OF RESPONSE. THE 40 GRADES TWO-FOUR PARTICIPANTS, MATCHED ON AGE, SEX, AND IQ, WERE…

GOALS OF THIS EXPERIMENT WERE TO GATHER COMPARATIVE DATA ON STUDENT ACHIEVEMENT IN TWO CLASSROOM ENVIRONMENTS, STUDENT AND FACULTY ATTITUDES, AND PERSONNEL AND TECHNICAL COSTS. CHI SQUARE ANALYSIS OF FINAL EXAMINATION SCORES SHOWED THAT THE CLASSROOM GROUP LEARNED SIGNIFICANTLY MORE THAN THE THEATER GROUP, BUT THE DISTRIBUTION OF COURSE GRADES DID…

Two methods of teaching a grammatical principle were compared in terms of initial learning results, positive and negative transfer, and retention. Forty-five pairs of sixth grade students, matched by sex and intelligence, formed two experimental groups. Group A was taught the principle and given practice with examples ("conventional" method) while…

The following topics are included in this document: (1) evaluation of plans for implementation of new systems; (2) macroevaluation of document retrieval systems; (3) microevaluation of retrospective searching; (4) evaluation of document acquisition functions; evluation of indexing and indexing languages; (5) evaluation of document screening; (6)…

A program called Experiment Writer (EW) was designed to enable students to use the computer to sample a range of experimentation situations. EW was used by 20 students in an Advanced Experimental Psychology course; hardware consisted of a PDP-10 computer, and a PDP-15 computer with 12K of core memory and two time-shared stations. Experimental…

Research investigated the utility of an alternative technique for the study of vigilance performance. The usual approach has been to study how well subjects responded to a signal of given difficulty; this technique altered the difficulty of the task to ensure a fixed level of performance. A computer-based, self-adjusting program presented…

Seven experiments are presented in this Science Study Aid to help students investigate the control of plant growth with chemicals. Plant growth regulators, weed control, and chemical pruning are the topics studied in the experiments which are based on investigations that have been and are being conducted at the U. S. Agricultural Research Center,…

Dissonance theory implies that relationships should exist between dissonance-reducing behaviors and measures of tension. It is suggested that dissonance-reducing behavior should be positively correlated across subjects with initial tension but negatively correlated with tension after dissonance-reducing behaviors have occurred. Thirty-six male and…
