A pretest-posttest control group design was used in a classroom experiment designed to determine whether the problem-solving performance of second grade students would be affected by systematic instruction in estimation. Participants were 36 students in two groups who were given daily lessons in measurement. The experimental group received a daily…

In an effort to provide information about the effect of computer use in schools on student achievement, attitudes, dropout rate, and learning time, a review of instructional computing research analyzed studies done between 1980 and 1987 using statistical summary procedures. Reviewers used a meta analysis procedure to calculate effect size as they…

This book describes the practice of using learner-centered software in special education. Following an introductory chapter, Chapter 2 provides a discussion of software that goes beyond drill and practice and at the same time fits easily into the existing subject areas of reading/language arts and mathematics. Chapters 3 and 4 discuss using word…

Part of a larger project, "The U.S. and the USSR: Choices for the 21st Century," that is aimed at developing curricular materials for use at the secondary, undergraduate, and adult education levels, this book helps high school students to think through some of the complex issues surrounding U.S.-Soviet relations and the nuclear arms race…

Blue ribbon commissions in the United States from 1965-1983 are discussed with attention to what makes a commission effective, the history of blue ribbon commissions, features of a commission, whether these commissions are useful on campus, and criticisms of blue ribbon commissions. Factors that contribute to the effectiveness of a blue ribbon…

"Critical thinking" has been defined as reasonable, reflective thinking that is focused on deciding what to believe or do. Since the social sciences require practitioners to ask relevant questions, develop appropriate evaluation criteria, generalize from observed facts, conceptualize hypotheses, and make judgements, critical thinking skills should…

This module is the seventh of 10 modules in the competency-based electronics series. Introductory materials include a listing of competencies addressed in the module, and a cross-reference table of instructional materials. Three instructional units cover: block diagrams; board-level repairs; and component-level troubleshooting. Each unit includes…

This study was conducted to identify what elementary school staff and district parents believed to be important elementary guidance services. A needs assessment questionnaire was given to all 112 staff members (principals, teaching staff, teacher aides, secretaries, and school nurse) in the district's 2 elementary schools. Fifty-eight completed…

A unit of study that introduces collecting, representing, describing, and interpreting data is presented. Suitable for students in grades 4 through 6, it provides a foundation for further work in statistics and data analysis. The investigations may extend from one to four class sessions and are grouped into three parts: "Introduction to Data…

The case study is designed to be used with the inservice training program developed by the Child-Centered Inservice Training and Technical Assistance Network (Syracuse, New York), which provides services to professional and paraprofessional personnel working with students with severe disabilities receiving their education in regular education…

The context of learning with computers is different from that of more traditional educational media because the computer is a new medium whose interactivity supports dynamic, evident, and malleable representations of abstract ideas. The model proposed addresses some mediating factors of the environment in which computers are used that affect…

Vitkus and Horowitz (1987) found that lonely people demonstrated adequate social behavior when they were assigned to controlling interpersonal roles. Despite this successful performance, they evaluated themselves and their behavior negatively. Study 1 replicated these findings and extended them to naturalistic interactions. In a hypothetical…

This document is the fourth of seven units developed by the Math Network Curriculum Project. Each unit, designed to be a 2-week module, is a teacher's guide which includes detailed directions along with the courseware and software needed. Teacher intervention in the non-computer activities that begin each unit is required, and the consistent use…

Because of its ability to record and represent process, the computer can provide a powerful, motivating, and as yet untapped tool for focusing the students' attention directly on their own thought processes and learning through reflection. Properly abstracted and structured, the computational medium can capture the processes by which a novice or…

Descriptions of the problem-solving strategies of experts solving realistic, computer-generated transmission genetics problems are presented in this paper and implications for instruction are discussed. Seven experts were involved in the study. All of the experts had a doctoral degree and experience in both teaching and doing research in genetics.…
