The Voyage of MIMI is a major educational project housed at Bank Street College (New York) which is directed toward the development of extensive television, computer software, videodisc, and print materials for use in science and mathematics education in grades 5-7. The first series has been completed, and includes a 13-part dramatic television…

Develops a division algorithm in terms of familiar manipulations of concrete objects and presents it with a series of questions for diagnosis of students' understanding of the algorithm in terms of the concrete model utilized. Also offers general guidelines for using concrete illustrations to explain algorithms and other mathematical principles.…

A study of fourth and fifth grade classes suggests that competitive math activities give boys an advantage where cooperative math activities generally give girls an advantage. Suggestions to help teachers balance their teaching methods to decrease disparities between boys and girls are made. (MT)

A 15-item story problem test was written at three readability levels (below grade 4, grades 4-6, above grade 6) by two methods (vocabulary control and sentence control). Six test forms were administered to 1158 children in grades 3-6. Readability level had no effect on problem difficulty. (Author/MNS)

Following a brief introduction to the LOGO programing language, describes its use in a sixth-grade classroom. The situations described illustrate students' growth while the choice of the situations illustrates teachers' growth. (JN)

Describes three studies in which students (N=515; N=60; N=135) were asked to indicate appropriate operations and numbers used in solving open mathematical sentences. Analysis of data and interviews suggest two error patterns: "finding a solution" and "inverse operation." Indicates that "finding a solution" strategy…

Several experiences with palindrome numbers are given, each leading to the "Law of 11." Conjectures for the reader to consider are included. (MNS)

Schumacher and Nash (1991) theorize that writing provides an avenue for people to reorganize their knowledge. Kieren (1988) is one of several researchers who theorize that children's school fraction experiences should begin with personal knowledge of fractions. The purpose of this study was to determine whether or not children who engaged in…

Twenty primary school students were randomly assigned by a matching procedure to either an experimental or control group. During the whole school year, both groups were taught mathematics according to the curriculum in the school; however, the groups followed different programs in fractions. Students in the experimental curriculum were provided…

Geared to intermediate-grade classroom teachers, a general framework for solving problems is promoted that has the following steps: (1) Get to know the problem, (2) Choose what to do, (3) Do it, and (4) Look back. Ways of using the framework and suggestions for problem-solving resources are included. (MP)

Reports on a collaborative research project with a middle school mathematics teacher. Discusses varied commentaries on mathematics teaching using an enactivist framework. Highlights the manner in which the teacher listens as a metaphoric lens through which to reinterpret practice, as a practical basis for teaching action, and as a means of…

Focused on two fifth graders in the Netherlands and studied two approaches to working with models in primary mathematics education: providing models versus designing models in coconstruction. Findings suggest that understanding may be improved by models students made themselves, and that students of this age are able to design models working…

An experimental study was conducted of 2 different approaches to the correction of consistent subtraction errors in 6 students aged 12-13. Tentative findings demonstrate the superiority of the old way/new way method compared to use of Multibase Arithmetic Blocks and place value charts. (JDD)

Describes a simulation-oriented computer microworld named CHANCE used to overcome the limitations of physical materials for experiments in teaching and learning introductory probability. Results of a teaching experiment conducted with four middle school and high school students are discussed. (15 references) (LZ)

Describes a one-week lesson in which gummy-bears candy was used to illustrate sampling procedures and to generate discussion and questions. Reports data results and students' reactions to problems of representation after holding an election. (MKR)
