Investigated the nature of pedagogical competency in student teachers identified as outstanding in mathematics, comparing their planning, teaching, and post-lesson reflections. Data from interviews, observations, and field notes found many commonalities among student teachers. They were not yet skilled in improving activities and explanations to…

Information processing researchers have assumed that algebra symbol skills depend on mastery of the abstract rules presented in the curriculum (Matz, 1980; Sleeman, 1986). Thus, students' ubiquitous algebra errors have been taken as indicating the need to embed algebra in rich contextual settings (Kaput, 1995; National Council of Teachers of…

"Principles and Standards for School Mathematics" states that in the middle grades "measurement concepts and skills can be developed and used throughout the school year rather than treated exclusively as a separate unit of study" (National Council of Teachers of Mathematics 200, p. 241). This article describes a collaborative activity that…

Working memory plays a key role in supporting children's learning over the school years, and beyond this into adulthood. It is proposed here that working memory is crucially required to store information while other material is being mentally manipulated during the classroom learning activities that form the foundations for the acquisition of…

This study used a diagnostic testing approach to compare the mathematics achievement of eighth-grade students across a sample of 20 countries, analyzing data from the Third International Math and Science Study-Revised (TIMSS-R, 1999). Using the rule-space method, student mastery was measured on 23 specific content knowledge and processing…

The purpose of this study was to examine the cognitive correlates of RD-grade skill in arithmetic, algorithmic computation, and arithmetic word problems. Third graders (N = 312) were measured on language, nonverbal problem solving, concept formation, processing speed, long-term memory, working memory, phonological decoding, and sight word…

In a two-day workshop, 12 teachers who had not previously used graphics calculators not only learnt how to use a calculator but also completed calculator tasks designed to explore their misconceptions and then learnt about students' difficulties. Observation of lessons taught subsequently by 6 of the teachers, and interviews with 15 of their…

In this article, the authors describe a collaborative effort involving 30 school districts in California's Silicon Valley that are seeking to overcome the ill effects of mandatory high-stakes standardized testing in mathematics. These districts administer, score, and analyze a common set of performance assessments in mathematics in a way that…

To evaluate the adequacy and efficiency of preschool education in California, the RAND Corporation has undertaken the California Preschool Study to improve understanding of achievement gaps in the early elementary grades, the adequacy of preschool education currently given, and what efficiencies or additional resources might be brought to bear in…

The teaching and learning of a complex section in "Theoretical Computer Science 1" in a distance-education context at the University of South Africa (UNISA) has been enhanced by a supplementary e-learning application called "Relations," which interactively teaches mathematical skills in a cognitive domain. It has tutorial and…

This guide, part of a series of workplace-developed materials for retraining factory workers, provides teaching materials for a workplace mathematics course. The course is a review of basic number concepts focused on helping participants to understand the meaning of numbers and arithmetic operations. The introductory materials include a course…

Previous studies, while not suggesting that all preschool programs will bring lasting benefits, demonstrate that early education can change the course of children's lives, especially children from disadvantaged backgrounds. This study dealt with early childhood education and school success, evaluating the effect of preschool attendance on reading…

This monograph presents data from a 1994 national survey on freshman seminars gathered from 1,003 accredited, two- and four-year colleges with student populations of over 100 students. The survey investigated the content and structure of freshman seminars in a mail survey of provosts/vice presidents for academic affairs at 2,460 institutions Among…

The paper discusses the results of a longitudinal study, conducted in Swedish public schools, of children in the sixth grade in 1979-80 (n=116) and children in the third grade in 1981-82 (n=123) with mild mental retardation who had not been labeled. The study replicates an earlier study on the incidence of mild mental retardation which was…

A comprehensive, needs-based portfolio assessment system was developed for use with adult basic education (ABE)/General Educational Development (GED) students at an adult education and job training center in Lewistown, Pennsylvania. Consultation meetings were held with ABE/GED instructors, students, administrators, and counselors to identify…
