The present study contrasted the robustness of the WSD and the F test to heterogeneity of variances. (Author)

The contention of this paper is that the obtained difference in a study by DuCette and Wolk, which indicated that giving options in an essay examination produces poorer test performance, was an artifact of the scoring procedures. (Author/RK)

This study is an examination of the environmental forces and curriculum involvement in open and closed classroom settings. (Author)

Study was concerned only with the impact of tutoring on the tutor's learning and attempted to determine whether tutors cognitively restructure the material in anticipation of teaching it to someone else. (Author/RK)

Practical methods for implementing true experimental designs in evaluation settings in which such designs are rarely used are presented. Particular attention is paid to educational settings. (Author/JKS)

A study investigated the relationship of traits measured by the California F Scale (a measure of anti-democratic attitudes) with changes in attitudes as measured by the Minnesota Teacher Attitude Inventory (MTAI) during a one-semester course of educational psychology. A 2 x 2 factorial design was used, classifying 132 sophomore education students…

This study tested four physical-political map layouts designed for pupils in grades 4-6. The project studied the effect of modifying traditional classroom and textbook maps on performance in map reading. The four map designs tested were the traditional map; a map using a unified legend, more elaborate symbols, and fewer type sizes and styles; a…

A research project conducted during the 1976-77 academic year in the Baltimore City Public Schools is investigating the effect providing staff development to teachers on how to teach with learning hierarchies will have on students' achievement scores and rate of learning. Twenty teachers participating in the study are taking a year-long course on…

There is a natural tension between experimentally designed studies and case studies, which differ in that they are not concerned with the interaction of variables in the quantitative and statistical sense. This paper describes a study that was not experimentally designed, but its major findings were generalizable to the overall population of…

A stratified random sample of 84 student teachers in secondary school academic subject areas was distributed into four treatment groups according to a trichotomization of their scores on the Minnesota Teacher Attitude Inventory (MTAI). Each student teacher taught two 20-minute lessons with the same content to different classes of five pupils. On…

A study was conducted to investigate the effects of interaction analysis feedback on the verbal behavior of student teachers. Forty randomly selected senior elementary education students at the University of South Florida were trained in interaction analysis, and each was observed for eight weekly 15-minute periods during student teaching. Data,…

This paper reports on an experiment designed to investigate the effect of structural and linguistic variables on level of difficulty in solving arithmetic word problems. Identification of such variables is intended to assist curriculum writers in preparing exercises at a specified level of difficulty for students at various age levels. The study…

Demonstrating and testing Conant's recommendation that teacher competence should determine certification, this four-phase study from 1964-68 developed and field-tested procedures for evaluating teacher competence and for determining how evaluation is affected by the beliefs of student teachers and observer-judges. Following the Phase I orientation…

A study was conducted by the Corvallis School District, Oregon, to examine the effectiveness of the use of video tape recording as a self-instructional inservice training tool and as a means of bringing about change in teacher behavior. Over a two-year period, 65 elementary school teachers were randomly assigned to one of five treatment groups…
