The objectives of the current study were to examine: (a) the effects of the Peer Mediation with Young Children (PMYC) program on mediators' and learners' mediation style in the context of maths teaching; and (b) the interaction effects of the intervention program, children's verbal ability, and maths level on pre-to post-intervention improvement…

The study describes the nature of pre-service teachers' idiosyncratic metaphors for the concept of statistical sample. These metaphors were investigated because of their potential to provide insight about individuals' content knowledge and how that content knowledge is enacted during teaching. Personal metaphors were elicited from 54 pre-service…

What people mean by randomness should be taken into account when teaching statistical inference. This experiment explored subjective beliefs about randomness and probability through two successive tasks. Subjects were asked to categorize 16 familiar items: 8 real items from everyday life experiences, and 8 stochastic items involving a repeatable…

Recent research into students' reasoning about variation refers specifically to notions of distribution that emerge. This paper reports on research where written responses, from tertiary introductory statistics students, were coded according to the level of consideration of variation. A hierarchy of reasoning about distribution is proposed, based…

This article describes Success Express, a program planned and implemented as part of a collaborative 1990 Javits project for gifted students between Lamar University and Texas A & M. The program has been continued by Lamar and Beaumont Independent School District as a two week summer program to identify high-potential, low-income 4-5 year olds…

The ability to integrate technology into instruction is among the characteristics of a competent mathematics teacher. Research indicates that the vast majority of teachers in Turkey believe the use of computers in education is important, but have limited knowledge and experience on how to use technology in their instruction. This paper describes…

This analysis indicated that from variables theorized to influenced score changes in NAEP reading scores from 1994-1998, two were the most consistent with pattern of correlations found in the data. Together, both median household income (AVGINC) and the percentage of students eligible for free and reduced-priced lunch (FRELCH) had fairly large…

Teacher-dominated classrooms with some student-centered elements are a perplexing phenomenon of Chinese mathematics classrooms. In-depth exploration of this phenomenon is helpful for understanding the features of mathematics teaching in China. This paper demonstrates how the teacher can encourage students to actively generate knowledge under the…

In individual interviews, 220 students in grades 4, 6, 8, and 9 were given one task, and 72 eighth graders were given three tasks to answer two questions: (a) Is a square the unit of measurement for an area for students in grades 4-8? and (b) Does a square have a space-covering characteristic for students in grade 8? The answers to both questions…

Recent teacher professional development in California tends to focus on increasing teachers' mathematical knowledge. In Australia, pedagogically focused programs are preferred. The two approaches are contrasted by comparing a Californian professional development model based on improving mathematical knowledge in number and algebra with a New South…

This article presents an in-class Monte Carlo demonstration, designed to demonstrate to students the implications of multicollinearity in a multiple regression study. In the demonstration, students already familiar with multiple regression concepts are presented with a scenario in which the "true" relationship between the response and…

Problem solving continues to be a major focus of K-12 mathematics education reform. This case study shows how a teacher's middle school mathematics instruction evolved from teaching problem solving as computation exercises to teaching how to select and implement combinations of problem solving strategies. The teacher's thinking about problem…

This article reports on the grouping practices used by a cohort of 10 newly qualified primary teachers for teaching mathematics in different English primary schools. It examines the factors that influence why these teachers group as they do. All the teachers grouped their pupils on the basis of achievement or perceived ability for mathematics. It…

The importance of algebra instruction has increased in the United States in the past few years. Thus, in most states, middle school students are required to take Algebra 1. Middle school students with math difficulties in inclusion algebra settings may require a different instructional approach. The purpose of this research was to compare student…

Staff development is aimed at changing practice. Change creates conflict. Little work has been done to gain insight into the conflict that teachers experience in the implementation of staff development. This study examines conflict in a staff development project aimed at increasing teachers' knowledge and implementation of problem-based integrated…
