Abstracts and comments are presented for 11 studies. There are two each on aspects of problem solving, mathematics achievement, and estimation. The remainder cover topics related to cognitive development, cognitive processes, evaluation, numeration, and student errors. Research as reported in RIE and CIJE between July and September 1982 is also…

This document consists entirely of materials presented at the Third International Conference held at Warwick University, England, from July 9 through 14, 1979. The items are collected and listed alphabetically by author. An opening address is included, and a total of 45 papers are presented, covering a wide variety of topics. (MP)

This study examined the curricular validity of the New Jersey Basic Skills test, a minimum competency test administered to all public school students in grades 3, 6, 9, and 11 to measure basic skills in reading and mathematics. Based on examinations of a Modified Caution Index, there were differences in the usual response patterns for both reading…

This material is designed to examine the research on how children acquire basic addition and subtraction concepts and skills. Two major lines of theories of the development of basic number concepts, called logical concept and quantification skill approaches, are identified. Major recurring issues in the development of early number concepts are…

This document primarily consists of papers scheduled for presentation at the third annual meeting of the North American chapter of the International Group for Psychology in Mathematics Education (NA-PME), held in September 1981, at the University of Minnesota. A total of 27 papers are arranged alphabetically by author. An additional three late…

The results of a field test which evaluated the training effectiveness of a new curriculum in the Naval Apprentice Training Program are detailed. The new mathematics curriculum was designed by Memphis State University to teach fundamental mathematical skills to low-aptitude sailors. The goal was to bring such sailors to at least eighth-grade…

Data from national and local studies have shown declines: (1) in the quality and quantity of mathematics and science instruction over the past 20 years; (2) in student enrollment in these subjects; (3) in student scores on standardized mathematics and science tests; and (4) in course offerings and enrollment in such foreign languages as German.…

Language syntax is discussed, followed by an overview of algbraic syntax. Evaluating algebraic expressions was chosen as the means to investigate the psychological basis of syntactic skills. Subjects' ability to perform evaluative tasks appropriately using standard algebraic notation was ascertained; then similar tasks were presented using a…

A group of 24 14-year-old students were presented with sets of algebra tasks using the Leeds Modelling System (LMS), a computer-based modeling system. Four months later, these same students were given a paper-and-pencil test which covered comparable tasks set by LMS. In addition, certain students were given detailed diagnostic interviews. A…

This paper reports the results obtained with a group of 24 14-year-old students when presented with a set of algebra tasks by the Leeds Modelling System (LMS). These same students were given a comparable paper-and-pencil test and detailed interviews some 4 months later. The latter studies uncovered several kinds of student misunderstanding that…

This project introduced microcomputers to small-scale construction trades programs through selected California community colleges. The computers were used for applications and computer-aided instruction in construction management and carpentry classes within the departments of vocational education. The project aimed to (1) define the uses for…

Developmentalists are convinced that within each young child a process of unfolding occurs to regulate learning in ways that make worksheets and the "force-feeding" of isolated skills inappropriate. Still, worksheets are enormously popular in early education, and math education assumes that number is learned through internalization. Why…

This report summarizes a five-volume research report on the classroom use and impact of ThinkAbout, an instructional television series designed to strengthen the reasoning skills of fifth and sixth graders and to review and reinforce language arts, mathematics, and study skills. It describes results of a 1979-80 research study which used three…

Three case studies describe and analyze the events occurring in three classrooms in the St. Louis metropolitan area during the first year (1979-1980) of the use of ThinkAbout, a series of 60 15-minute programs designed to strengthen the reasoning skills of fifth and sixth graders, and to review and reinforce language arts, mathematics, and study…

This study explored the effects of a left-hemispheric, right-hemispheric, or integrated teaching approach on students' achievement and attitudes. One hundred eighteen second-grade pupils were randomly assigned to four groups to receive two weeks of instruction on geometry and measurement with: (1) a formalized, structured-textbook approach; (2) a…
