An investigation of the effectiveness of a mathematics course for preservice elementary teachers showed that the use of mastery learning principles in a traditional classroom setting can be effective. (SD)

Investigates relationships between question level, response level, and lapse time for a total of 238 questions asked by student teachers on the junior high and senior high levels. Classroom interactions were taped and questions dichotomized into memory (knowledge) and above memory (comprehension, application, analysis, synthesis, evaluation)…

The early use of the distributive law can aid students in learning addition of fractions and provide rapid approaches to computation involving other operations. (SD)

Investigates the perceptions of teachers, principals, and consultants concerning the importance of identified inservice activities, provided by a consultant, to implementing teachers. One hundred-forty-five educators participated in a program in which Science--A Process Approach (SAPA) materials were introduced. Collectively, educators considered…

Suggests the use of the computer for drill and practice, for simulation and game playing, and for problem solving in the elementary school. Offers advice on the teaching of terminal operation to young children. (CP)

Describes the content, evaluation, and operation of a high school physics course intended for college bound non-science majors. Discusses some advantages and challenges of contract learning. (CP)

Tables of life expectancy can provide data for use in a great variety of problems related to probability theory. (SD)

Summarizes findings of 24 studies in which attempts were made to correlate achievement in college chemistry to many variables. A list of the most promising factors is provided. However, the author found no conclusive predictors in reviewing the research. (CP)

A pilot project conducted in a fifth-grade class was designed to allow students to work on basic skill development at their own levels of competence. The grouping and regrouping of students after periodic diagnosis was a major feature of the project. (SD)

Reports on a study in which high school biology students were divided into two groups: one read "Scientific American" articles and the other group read annotated "Scientific American" articles. Although there was no significant difference between means on an achievement measure of the groups, the author reports that students preferred the…

Provides and explains a teacher self-evaluation instrument designed to measure inquiry teaching. Recommends that a lesson be videotaped after which the educator scores the presentation on the criteria of lesson content, student behavior, teacher behavior, and questioning techniques. (CP)

An experiment was performed to determine the effects of syntax complexity and vocabulary difficulty of problem statements on the ability of students to solve them. It was concluded that these variables do have an effect on students' performance, especially in cases of students with low general ability or reading problems. (SD)

Students in nine classes were randomly assigned to treatment groups receiving (1) written comments on their homework papers or (2) no comments. In two of the classes, the students receiving comments showed achievement superior to that of the others. In the remainder of the classes there was no difference. (SD)
