How People Learn(Bransford, Brown, & Cocking, Eds.)National Academy Press, 1999
BUT….
The sciences and technologies of learning have had far too little influence on:
• curriculum• assessment • teacher development• school reform• public views of learning/teaching
A Grand Design Challenge: Connecting ‘distributed expertise’ to
augment ‘collective intelligence’ • We collectively know a lot more than we utilize
about uses of ICT to improve learning and teaching (collective intelligence)
• Exploit ICT itself in strategies for leveraging distributed expertise about learning and teaching with technologies
• Identifying and connecting distributed expertise
• Creating and studying “Networked Improvement Communities” (NICs)
Networked Improvement Communities as a powerful leveraging strategy for tackling our Grand Design Challenges
• A NIC is a coalition of organizations each engaged in a similar improvement process;
• A NIC networks these organizations and crafts new mechanisms for improving their isolated improvement processes; and
• A NIC builds value and leverages knowledge for distributed communities.
• Thanks to Doug Engelbart as NIC pioneer

The Context of Teacher Learning Needs and Marketplace
• U.S. context of teacher workforce development, appearance of for-profits
• Teachscape as an example of response to a Grand Design Challenge
• Issues of “addressable market” size and capability
• Key enabling technological developments
What is happening to teaching?
• Huge turnover and new US workforce preparation need—2 Million new teachers needed by 2008-2009 (3.1 Mil today)
• Increasingly accountable, but unprepared for new standards and assessments
• Weakly-defined professional career path for lifelong learning
• Yet…emerging higher standards for teaching (NBPTS, INTASC)
• And rapid growth of alternative certifications
• Changing roles of post-secondary institutions and the private sector
““There is a national crisis in teacher professional development”There is a national crisis in teacher professional development”
-Glenn Commission, 1999
Current state of in-service TPD
• Teachers continually isolated; rare mentoring
• Dominant mode of delivery is one-day off site workshops with no follow-up
• Teaching strategies too rarely linked to content, advances in learning research, standards, or modeled in classroom settings
• No assessment tools or results orientation
• Market dominated by fragmented, local non-scaleable solutions
• Little use of technology
• No “just-in-time” teacher learning support
• District level TPD planning or management tools are lacking
“U.S. teachers …. have no time to work with or observe other teachers; they experience occasional hit-and-run workshops that are usually unconnected to their work and immediate problems of practice. [Effective TPD cannot] be adequately cultivated without the development of more substantial professional discourse and engagement in communities of practice.”
— Darling-Hammond and Ball (NEGP, 1997)
A new approach to teacher professional development
• A scaleable, Web-based, teacher professional development system that offers teachers “just-in-time” access to annotated video cases and distributed learning courses, linking pedagogy to content, while also providing tools for school administrators to plan and manage professional development
• A company based in New York with partners including AFT, NBPTS, Intel, SRI International, ABC News
• We have focused efforts to bring learning sciences and educational research as well as practical knowledge on teacher communities into Teachscape’s products and services, both on-line and on-site
• Video case studies of research-informed and standards-based teaching strategies in literacy, math, and science
• Annotated with teacher reflections, expert commentaries
• Embedded assessment activities with rubrics
• Structured community discussion around case materials
• Distributed learning courses built up from collections of video case studies from digital library -- for use in schools and at home
• Partner with districts to develop plans to meet distinctive needs of their schools and teachers and build PD capacity with existing staff
• Supported by on-site and on-line mentoring by participating districts
• Supported by on-line communities of practitioners -- enabling peer-peer collaboration and continuous feedback for “teacher reflection on practice”
• Teachers can earn CEUs, academic credits
Approach for TPD
Why case studies?
Because of the complex interplay of knowledge and skills that comprise a teacher’s daily work.
“I envision case methods as a strategy for overcoming many of the most serious deficiencies in the education of teachers. Because they are contextual, local, and situated—as are all narratives—cases integrate what otherwise remains separated. Content and process, thought and feeling, teaching and learning are not addressed theoretically as distinct constructs. They occur simultaneously as they do in real life, posing problems, issues, and challenges for new teachers that their knowledge and experiences can be used to discern” (Lee Shulman, 1992, p. 28)
“Living Cases”
• Visible models: A video-based narrative account of how one or more teachers experienced a problem, the strategy used to deal with it, and the outcomes
• Principles underlying the teachers’ practices
• Guided practice: Guidance in reflective use comparing cases to experience is instrumental to changing teaching practices.
• Reflective community: Cases created as fertile soil for reflective community dialog, elaboration, multiple interpretations-- not as sterile packages of inert ‘wisdom.’ They extend the published case-and-commentary model with on-line commentary, dialog.

Benefits of on-line TPD services
• Convenient, self-paced learning to meet in-service certification requirements (typically 30 hours TPD per year)
• Access to professional “communities of practice”
• Ongoing, on-line mentoring with district TPD professionals or faculty
• Districts may better scale the certification of teachers, at lower cost per teacher than off-site models

Emerging designs for distributed teacher learning environments
• Uses of generic course platform “shells” (e.g., Blackboard, WebCT)
• Special-purpose proprietary course platforms (e.g., Classroom Connect, Teachscape)
• Use of web-accessible video materials of teaching practices (e.g., Teachscape, Teachstream, PT3 grantees, PBSTeacherLine)
• Use of on-line community tools for meetings, moderated events (e.g., TAPPED IN, Teachscape, Classroom Connect)
• On-line course “malls” (e.g., AT&T Learning Network)
Research Plans
• Scope of activity (10,000 teachers in first school year in 10-15 districts; scale to 100,000 teachers in 3 years)
• Research capabilities built into the Teachscape platform
• Member profiles provide information on teachers’ experience, specializations, licensure and demographic data
• Member’s case and chapter ratings, and their community responses re: cases and needs can be studied by profile characteristics
• Learning Planner provides tool for assessing context in which they work, their PD opportunities, and specific areas they’d like to learn or improve
Teachscape Summary
• New media web-based publishing enables broad access to research-based teaching practices, and community tools make new learning networks possible that leverage distributed expertise
• A convergence is underway between traditional on-site teacher education programs and on-line teacher professional development services
• Complementary strengths of public and private sector may be highly leveraged for improving teacher learning and professional growth
• Developing NICs powerfully amplifies your ability to solve important interdisciplinary problems no one can solve alone
