Describes an experimental course requiring writing assignments as a regular part of the course. Summarizes common problems with student writing in mathematics. Reports effective procedures of the course, such as peer response, double submission, and efficacious instructor responses. (YP)

Effective teaching behaviors that have cognitive and affective learning effects on students' were identified in this study. Subjects were 50 grade-8 Dutch mathematics teachers. Findings indicate more teaching behaviors have a positive effect on mathematical knowledge than have a positive effect on students' attitudes toward mathematics. (IAH)

Used are test and interview data to extract evidence as to what level tenth graders have coordinated the worlds of arithmetic and algebra and can move freely between them. More dissociation is shown than was expected. (Author/MVL)

The performance of sixth and seventh graders on a variety of tasks involving estimation and reasonableness of results were studied. Also examined was the effect of a short unit of activities on these two topics. Correct answers approximately doubled after instruction. (MNS)

Describes four mathematics teachers' classroom discussions with small groups in their first year secondary (11-12 years old) classrooms. Analyzes interview results from one student in each group. Topic of the classroom was division of fractions. (YP)

Provides a short BASIC program, RANVAR, which generates random variates for various theoretical probability distributions. The seven variates include: uniform, exponential, normal, binomial, Poisson, Pascal, and triangular. (MVL)

Describes the "workability" of a K/1--kindergarten/first grade--multi-age classroom. (BB)

Two incidents involving novice teachers with classes in grades 7 and 10 are presented. Then considered are the nature of intuitive mathematics and contributions computers can make to such intuitive mathematics, particularly in Algebra. (MNS)

This article examines the level of understanding by children (six- to seven-year-olds) of the addition and equality symbols. The article reports that about half of the subjects were unable to write the mathematical expression of simple addition while they were able to do it verbally. (YP)

This article discusses the classroom use of discovery of number pattern. Provided are examples of a table of squares, multiplications of numbers, and algebraic expressions. (YP)

A theory is proposed for how students develop competence with the written symbols of decimal fractions. Competence is viewed as the cumulative and sequential mastery of four separate cognitive processes. The theory was tested with small groups of students, most of whom were able to acquire the first two processes. (MNS)

Discusses the problems of and some solutions presented by the American mathematics education reform movement. Describes ideas concerning criteria for curriculum, assessment, learning, teaching, and teacher education. Proposes several recommendations for a new agenda. (YP)

Discussed are the range and balance of learning activities in the classroom, including discussion of the various roles of the people involved. The analysis is based on records of observations of 174 mathematics lessons with students aged 12-14; microcomputer use was integrated as a teaching aid. (MNS)

Discussion of the use of electronic networks for learning activities highlights the Noon Observation Project in which students in various locations measured the length of a noontime shadow to determine the earth's circumference. Electronic pen pals are discussed, and the roles of the network and of the class are described. (LRW)

Documents changes in 2 elementary teachers' thinking about instruction in reading or math after 1.5 years as participants in in-service programs designed to promote constructivist teaching practices. Interviews conducted before and after the programs indicated that, over time, teachers gave stronger emphasis to inquiry as a component of a subject…
