The paper suggests that the problems are of two different kinds. One kind involves difficulties that could be overcome; the other kind is rela...

Our discussions of the plenary lectures, and of the short presentations, as well as our continued probing of the group’s core
questions led to a greater appreciation of the following:
1.
Some contemporary researchers are designing projects that aim to develop both knowledge and practice. This is different from
developing theory and then “putting...

In this paper we explore the issue of interdependency of theory and research findings in the context of research on the practice
of mathematics teaching and learning at school. We exemplify how analyses of a lesson by using two different theoretical perspectives
lead to different interpretations and understandings of the same lesson, and discuss th...

This paper is an initial investigation into the practice of providers of professional development for teachers of mathematics. The study examines the work of two providers of professional development for teachers of mathematics. Both provided professional development while working with teachers on implementing a new mathematics curriculum for seven...

In this chapter we consider what it takes to learn to conduct research in mathematics education. We argue that learning any
complex practice requires opportunities to unpack its components in order to see what underlies competence performance. Many
of the components of successful research remain implicit and are left to new researchers to glean fro...

The implementation of new standards in science and mathematics education necessitates an intensive and comprehensive professional development of science and mathematics teachers. Israel, which currently is in the process of reforming school science and mathematics, constructed a continuous lifelong framework for such professional development. This...

This study investigates four seventh-grade teachers' awareness of students' tendency to conjoin or 'finish' open expressions. It also investigates teachers' ways of coping with this tendency. Three types of data were collected: 1) lesson plans, 2) lesson observations, and 3) post-lesson interviews. The analysis showed that the two experienced teach...

This paper discusses two possible approaches to (-8)1/3. The first is that (-8)1/3 = 3(-8) = -2. The second is that (-8)1/3 is undefined. The pros and cons of each of these approaches are considered and some implications to teacher education are specified.

Teachers’ ability to help students learn mathematics requires an understanding of student thinking. No less important is what teachers do with this knowledge; i.e. the nature of their decisions and actions which are based on this knowledge. Two interviews were conducted: one with two junior‐high school teachers, and the other with two eleventh grad...

Pedagogical content knowledge is made up of several components. In this paper we concentrate on one of these: teachers' planned presentations of the subject-matter. We deal with two main sources of this component of pedagogical content knowledge: knowledge about the subject-matter and knowledge about students. Illustrations are given in two mathema...

This study examines differences in connectedness in instruction between two novice teachers and an expert teacher. Three types
of data related to lessons on equivalent algebraic expressions were collected: lesson plans, lesson observations, and post-lesson
interviews. Although connectedness is an important characteristic of mathematics teaching and...

Simila rity is an important topic in geometry, basic to understanding the geometry of indirect measurement, proportional reasoning, scale drawing and modeling, and the nature of growing. When United States’ teachers were asked to rate the importance of this topic for the Second International Study of Mathematics, they rated similarity of plane figu...

To teach the arithmetic-driven curriculum of the past, one needed little more than computational skill with the standard algorithms and a text to provide practice. That is no longer the case. To prepare a teacher dedicated to helping children think mathematically requires a very different experience with mathematics than the traditional college cou...

It is widely accepted today that teachers should be aware of, and knowledgeable about, stu- dents' mathematical learning. It is believed that such awareness and knowledge signifi cantly contribute to various aspects of the practice of teaching. In this chapter, we critically examine this commonly held belief. We begin this chapter by interpreting w...

Teachers are expected today to assess student understanding by using a combination of various assessment methods and tools. Among them, observing students solve problems in class and listening to their mathematical discussions. Yet, not much attention has been given to the question whether teachers need to learn these practices. This study begins t...

This paper analyzes the ways proof ideas in an algebra lesson were offered to stu-dents (1) by two different teachers, and (2) in two different classes taught by the same teacher. The findings show differences between the two teachers, and between the two classes taught by the same teacher, regarding the proof ideas made available to learn in the l...

It is widely accepted today that teachers should be aware of and knowledgeable about students' mathematical learning, as this significantly contribute to various aspects of the practice of teaching.
