Facilitating mathematical investigations with teachers will help improve their teaching!

Because a student's learning depends so heavily on teacher quality, districts and state departments of education, colleges, and universities are called upon to strengthen their teacher preparation and professional development programs. Yet college mathematics courses are often criticized for being disconnected from the mathematics that teachers are asked to teach. The Facilitator's Guide to Ways to Think About Mathematics is designed to close this gap.

National and state standards and frameworks suggest that mathematical investigation, problem solving, and exploratory learning should play a central role in mathematics lessons. It is therefore necessary for teachers to experience mathematical explorations as learners themselves, which places new demands on professional development facilitators and preservice educators. This guide provides resources for facilitators to use while they are planning and implementing courses and workshops using Ways to Think About Mathematics.

This guide and the accompanying CD-ROM contain:

  • Commentary on the activities
  • Pedagogical suggestions (materials sequencing, promoting active participation, adapting to the needs of particular teachers)
  • Various solution strategies
  • Additional reading and problems tied to the content of the main text
  • Sample solutions for all problems and discussion questions

Ways to Think About Mathematics and the Facilitator's Guide will provide staff developers, preservice educators, and math department chairs with all the necessary tools to provide high-quality staff development in secondary mathematics. The materials were funded by the National Science Foundation and successfully field-tested in a wide variety of professional development and preservice settings.

Steve Benson

Steven R. Benson is an Associate Professor of Mathematics at Lesley University in Cambridge, Massachusetts, where he teaches a variety of mathematics content courses for traditional undergraduate students and in-service mathematics teachers. Before joining the Lesley faculty, Dr. Benson was a Research Scientist at Education Development Center, Inc., where he was involved in a wide variety of projects, most of which involved the development of curricula for mathematics students and teachers. He has also facilitated preservice and in-service teacher professional development workshops across the U.S. and internationally (including serving as consultant to the Ministry of Education in Azerbaijan), directed a research project investigating the genesis and development of mathematical talent in Mathematical Olympians, and edited the problem calendar section of the Mathematics Teacher journal published by the National Council of Teachers of Mathematics. Prior to joining the EDC staff in June 2000, he held mathematics faculty positions at St. Olaf College, Santa Clara University, University of New Hampshire, and University of Wisconsin-Oshkosh, and is currently a co-director of the Master of Science for Teachers program at the University of New Hampshire. He received his PhD from the University of Illinois, working under the direction of Leon McCulloh in algebraic number theory.

Susan Addington

Susan Addington is a professor of Mathematics at California State University,San Bernardino. Though her doctoral work was in arithmetic algebraic geometry (a field that includes almost every mathematical area except statistics),she now spends most of her time thinking about math education. Her educational interests include teacher preparation (elementary through college), ethnomathematics, and the use of technology to teach traditionally difficult ideas. Susan is married to David Dennis, a math educator, historian of mathematics, jazz saxophonist, and virtuoso gardener.

Nina P.Arshavsky is a Math Coach at Boston Public Schools, providing professional development to high school math teachers. She received her doctoral degree in educational psychology from the University of Wisconsin-Madison and taught mathematics in middle and high schools in both Russia and the US. Dr. Arshavsky worked on a variety of research, professional development, and curriculum development projects in the Center for Mathematics Education at EDC and is a co-author of Impact Mathematics: Algebra and More for the Middle Grades, a comprehensive 6-8 mathematics curriculum. She has published and presented numerous research papers, and has taught college courses in cognitive development and human development in infancy and early childhood.

Al Cuoco

Al Cuoco is Senior Scientist and Director of the Center for Mathematics Education at Education Development Center. Before coming to EDC, he taught high school mathematics for 24 years to a wide range of students in the Woburn, Massachusetts public schools. A student of Ralph Greenberg, Dr. Cuoco received his Ph.D. in mathematics from Brandeis; his mathematical interests and publications have been in algebraic number theory. His favorite publication is his 1991 article in the American Mathematical Monthly, described by his wife as “an attempt to explain a number system no one understands with a picture no one can see.”

E. Paul Goldenberg

E. Paul Goldenberg is a Senior Scientist and the Principal Investigator of three recent NSF-funded projects: Connecting with Mathematics, materials for teacher professional development programs; Problems with a Point,a Web-accessible, searchable database of orchestrated problem sets; and Math Workshop: A Comprehensive Elementary Curriculum for Skill, Mathematical Ability, and Real Thinking, a project that will develop materials for a K-5 comprehensive mathematics curriculum that promotes rather than requires professional development. He was previously PI on the Connected Geometry curriculum development project, and of a 3-year,NSF-funded research project into the nature of learning with geometry software. He has over 35 years of experience in elementary, secondary, and post-secondary teaching, teacher enhancement, and education research. He is widely published and has conducted workshops and seminars on a variety of topics in mathematics education.

Eric Karnowski

Eric Karnowski is a senior mathematics associate at Education Development Center (EDC) in Massachusetts. He has worked in mathematics education for 25 years, initially as a teacher, then as a textbook editor, and finally as a curriculum developer and teacher professional development provider. Since joining EDC, he has directed the development of the K–5 program Think Math! and written numerous activities for the award-winning Problems with a Point website. He directed projects to develop several online teacher professional development courses for PBS TeacherLine, Louisiana Algebra 1 Online Professional Development, and most recently, the National Board of Professional Teaching Standards in both mathematics and science. In addition, he was a contributing author on Ways to Think about Mathematics and the MathScape curriculum.

Prior to joining EDC, Karnowski had the distinct privilege to edit influential secondary textbooks for Janson Publications and Everyday Learning, including Contemporary Mathematics in Context by the Core-Plus Mathematics Project, Contemporary Calculus by the North Carolina School of Science and Mathematics, and Impact Mathematics by EDC. He received a B.S. in Liberal Arts (honors mathematics) and an M.S. in Mathematics, both from the University of Tennessee, Knoxville. He currently lives in Boston with his husband, Mark, and two large cats, Endora and Tabitha.
