 Introduction

 Online Professional Development

 Is it attractive to teachers?
 Why is the Math Forum developing it?
 What's an effective model?

 NSDL Online Teacher Workshops
 Using Technology and Problem Solving to Build Algebraic Reasoning
 designed for middle school teachers (note elementary opportunity)
 workshop goal: enable teachers to explore how technology can help students build algebraic reasoning as they model and solve contextualized problems using a variety of representations, including graphs, tables, equations, and words
 workshop design
 workshop fees covered by an NSF grant
 research questions
how to best provide an online math learning community
identify leaders
cost effective
 within the context of our NSDL library project  Math Tools, A community library of technology tools, lessons, activities, and support materials for teaching and learning mathematics.

 Upcoming Teacher Workshops:
Grades 59: http://mathforum.org/nsdl_mathtech/
Using Technology and Problem Solving to Build Algebraic Reasoning
Teachers will explore how technology can help students build algebraic reasoning as they model and solve contextualized problems using a variety of representations, including graphs, tables, equations, and words.
Grades 35: http://mathforum.org/toolsandconcepts/
Tools for Building Math Concepts
This workshop introduces the use of computers to develop understanding in these areas through the exploration of patterns and analysis of data.

http://mathforum.org/tpow/index.direct.html
Technology Problems of the Week (tPoWs) are problemsolving challenges modeled on our Problems of the Week that take advantage of interactive mathematics tools such as Java applets, Geometer's Sketchpad, Fathom, or spreadsheets. Students are invited to use the link "Submit your answer" to share their solutions, and then "selfmentor" using specially designed hints, checks, and suggestions for extensions.
