In this paper, we analyze an investigative situation proposed to a class of 5th graders in a primary school. The situation is based on the following task: In a sale with group rates on a sliding scale, the students must find the lowest possible purchase price for a given number of tickets. A study of students' arguments made it possible to…

As children make the transition to school, many things may change for them. Among these are the ways they interact with curriculum areas such as mathematics. This paper explores some of these changes by considering examples of children's mathematical experiences in prior-to-school and school settings and analysing them in terms of the mathematical…

The purpose of this study was to investigate to what extent studying topics in a cultural context affected African American students' achievement. Mathematics achievement was measured by a pre-assessment and post-assessment. The literature addresses the fact that all students can benefit from learning about culture and mathematics. Several…

This paper examines the development of student functional thinking during a teaching experiment that was conducted in two classrooms with a total of 45 children whose average age was nine years and six months. The teaching comprised four lessons taught by a researcher, with a second researcher and classroom teacher acting as participant observers.…

This paper reports a study of how students may connect the limiting process inherent in the derivative to the limit of the difference quotient (LDQ) when solving problems. The data was collected mainly through task-based interviews with five eleventh grade students. It was found that the students used various kinds of limiting processes and…

This article outlines the use of the online "SpeakEasy" communication package in two sections of a mathematics methods course in an elementary education teacher certification program. The instructional uses of "SpeakEasy" are described, with specific attention to the manner in which it was woven into the fabric of the course and made central to…

This study examines one child's use of computational procedures over a period of 3 years in an urban elementary school where teachers were using a standards-based curriculum. From a sociocultural perspective, the use of standard algorithms to solve mathematical problems is viewed as a cultural tool that both enables and constrains particular…

This paper examines the classroom practices of three teachers teaching mathematics at the 5th grade level in three Singapore schools. Using a video-coding scheme, a series of lessons was coded into relevant phases comprising problem solving, teaching concepts/skills, going over assigned work, and student activities. It explores the teachers'…

This paper raises issues motivated by considering the "identity" of problem solving. This means that we are concerned with how other mathematics education topics impinge on problem solving, and with themes that naturally arise within the problem-solving agenda. We claim that some of these issues need more attention by educational research, while…

This article describes an approach for introducing the unit concept in a mathematics content course designed for preservice elementary mathematics teachers. Classroom activities presented in the article emphasize the awareness, flexibility, and importance of the unit concept. Dialogue with selected preservice teachers is included and reveals some…

We present a project for a differential equations class: an analysis of an H. G. Wells story in which is given a submersible's descent time, its ascent time, and its eruption from the surface before splashdown. (Contains 5 figures.)

An integral part of all initial teacher education programs is the school-based practicum where pre-service teachers get an opportunity to develop their teaching skills and knowledge in a classroom setting. Many have suggested that these experiences are very powerful in shaping pre-service teachers' views of teaching because they are perceived as…

The note discusses ways in which technology can be used in the calculus learning process. In particular, five MATLAB programs are detailed for use by instructors or students that demonstrate important concepts in introductory calculus: Newton's method, differentiation and integration. Two of the programs are animated. The programs and the…

There is no common agreement on the meaning of the word "understand". However, there is agreement on what students should be able to do with material they understand. Bloom et al. discuss kinds of tasks a student should be able to do, provided that the student understands. In a similar way, Biggs and Collis provide a taxonomy intended to evaluate…

This article describes the process used in elementary mathematics content courses to engage preservice teachers in problem-solving activities to enhance their understanding and ability to analyze nonroutine problems. Through this process, preservice teachers' competencies and confidence with these problems improve. (Contains 7 figures.)
