One of the great strengths of Jim Kaput's research program was his relentless drive towards scaling up his innovative approach to teaching the mathematics of change and variation. The SimCalc mission, "democratizing access to the mathematics of change," was enacted by deliberate efforts to reach an increasing number of teachers and students each…

Identifies key questions concerning children's intuitions and conceptions of probabilistic notions. Research on the theoretical framework for probability studies, misconceptions and strategies, and pupil attainment is reviewed, and the methodology is evaluated. Finally, implications for classroom practice are discussed. (MNS)

This study involved 48 students ages 9 to 12. The 29 experimental group students, divided into small groups, performed learning exercises designed to improve skills in analyzing and processing expressions frequently included in addition and multiplication problems. The exercises helped significantly to improve problem-solving performance. (MNS)

Investigated was the influence of socioeconomic status, entry style, and instructional variables on postsecondary mathematics performance of students in New Guinea. The pattern of results indicated that the performance of students could be more meaningfully grouped based on entry style rather than on mode of instruction. (Author/CW)

Two teaching studies were conducted, based on a descriptive framework and diagnostic interviews described previously. In the pilot study, low-achieving students were taught individually; in the main study, they were taught in a group. Performance improved in both cases. (MNS)

An alternative explanation is presented for the pattern of relative difficulty of arithmetical word problems to that suggested in a 1983 article. It is argued, that for many problems, much of the symbolic manipulation is accomplished externally, not internally. (MNS)

Compared was the mathematical performance of secondary school students for whom a graphic calculator was a standard mathematical tool, with that of students of similar background without regular access to graphing technology. Increased achievement on symbolization tasks, especially for females, was shown for students who used the graphing…

Ideas on a teaching-learning theory of ratio are presented. Views of children and of members of an international panel are presented, and five questions and their responses are compared with real classroom experience. (MNS)

Discussed is the transfer of the teacher education system into the university sector in Turkey. The needs for a new model for student assessment, and to select and attract more capable and committed individuals into teaching are identified. (Author/CW)

Comparisons were made between teacher and pupil perceptions of eight facets of the mathematics environment. Teacher perceptions tended to differ from pupil perceptions although not always in the hypothesized direction. (Author/CW)

Examines the similarities and differences in beliefs about the effective teaching of mathematics held by teachers from two different sociocultural backgrounds. Data were collected using a part of the Teacher General Classroom Process Questionnaire of the second IEA Mathematics Study. (Author)

Learning environment that facilitated the acquisition and expression of procedural skills in LOGO was set up for children in the 10- to 12-year range. Ten participants were placed in a series of situations that required them to manipulate programing procedures in LOGO. Analysis of children's behavior revealed their competence in manipulating…
