According to NCTM's Principles and Standards for School Mathematics, "Technology is essential in teaching and learning of mathematics; it influences the mathematics that is taught and it enhances students' learning." How does research inform this clarion call for technology in mathematics teaching and learning? In response to the need to craft appropriate roles for technology in school mathematics new technological approaches have been applied to the teaching and learning of mathematics, and these approaches have been examined by researchers world-wide.
The second volume has a dual focus: cases and perspectives. It features descriptive cases that provide accounts of the development of technology-intensive curriculum and tools. In these cases the writers describe and analyze various roles that research played in their development work and ways in which research, curriculum development, and tool development can inform each other. These thoughtful descriptions and analyses provide documentation of how this process can and does occur. The remaining chapters in the second volume address research related issues and perspectives on the use of technology in the teaching and learning of mathematics. The lessons learned from the research presented in these volumes are lessons about teaching and learning that can be applied more broadly than solely in technological settings.

Nathan Carter's colorful text, Visual Group Theory, approaches the learning of group theory visually. Its topics and theorems are accompanied by visual demonstrations of the meaning and importance of groups, from the basics of groups and subgroups through advanced structural concepts such as semidirect products and Sylow theory. It allows students to see groups, to experiment with groups—and to understand the significance of groups, subgroups, homomorphisms, products, and quotients.
Defining groups as collections of actions, the opening chapters anchor readers' intuitions with puzzles and symmetrical objects. This approach leads to Cayley diagrams, which embody the visualization technique central to the book because of their unique ability to make group structure visually apparent.
Highlights:
  • Includes more than 300 full-color illustrations
  • Moves from the basics of group theory to Sylow theory and Galois theory
  • An applications chapter shows how group theory describes the symmetry of crystals, dancing, art, architecture, and much more
  • The book is an ideal supplement to a first course in group theory.
Contents:
Preface. Overview. 1. What is a group? 2. What do groups look like? 3. Why study groups? 4. Algebra at last 5. Five families 6. Subgroups 7. Products and quotients 8. The power of homomorphisms 9. Sylow theory 10. Galois theory. Answers to selected exercises. Bibliography. Index of symbols used. Index.

Teachers Engaged in Research: Inquiry in Mathematics Classrooms, Grades 3-5

The goal of this series is to use teachers' accounts of classroom inquiry to make public and explicit the processes of doing research in classrooms. Teaching is a complex, multi-faceted task, and this complexity often is not captured in research articles. Our goal is to illuminate this complexity. Research that is done in classrooms by and with teachers is necessarily messy, and our stance is that the ways in which this is so should be articulated, not hidden. Through the chapters in this volume we learn about the questions that capture the attention of teachers, the methodologies they use to gather data, and the ways in which they make sense of what they find. Some of the research findings could be considered preliminary, others confirmatory, and some may be groundbreaking. In all cases, they provide fodder for further thinking and discussion about critical aspects of mathematics education.

This booklet is intended for high-school students interested
in mathematics. It is concerned with approximating real
numbers by rational ones, which is one of the most captivating
topics in arithmetic.
…
Continued fractions represent one of the most perfect
creations of 17-18th century mathematicians: Huygens, Euler,
Lagrange, and Legendre. The properties of these fractions
are really striking.
The following should be borne in mind when reading this
booklet. Topics easily understandable are presented in normal print,
while those more difficult are given in small print. Proofs of some theorems given in small print may be omitted safely. These theorems will necessarily be taken for granted. However, mathematics is not just reading for entertainment. A future mathematician as well as a physicist or an engineer has to acquire skill in dealing with  mathematical constructions and proofs. So take a pencil and a sheet of  paper and study carefully the topics given in small print. You may succeed in simplifying some proofs or finding better ones.
The book was translated from the Russian by V. I. Kisin and was first published by Mir Publishers in 1986.

Approaches to Studying the Enacted Mathematics Curriculum

Curriculum materials are among the most pervasive and powerful influences on school mathematics. In many mathematics classes, student assignments, the questions the teacher asks, the ways students are grouped, the forms of assessment, and much more originate in curriculum materials. At the same time, teachers have considerable latitude in how they use their curriculum materials. Two classes making use of the same materials may differ markedly in what mathematics content is emphasized and how students are engaged in learning that content. This volume considers a variety of research tools for investigating the enactment of mathematics curriculum materials, describing the conceptualization, development, and uses of seven sets of tools. Mathematics education researchers, curriculum developers, teacher educators, district supervisors, teacher leaders, and math coaches will find insights that can improve their work, and guidance for selecting, adapting, and using tools for understanding the complex relationship between curriculum materials and their enactment in classroom instruction.
