“Hot Technologies” for Net Learning Advances Roy Pea SRI International Center for Technology in Learning A TeleLearning-NCE Board of Directors Roundtable Discussion
Overview • Setting the context (CILT, CTL) • Social networking apps (ICQ) • Recommender systems (NetPerceptions) • Educational object economies (EOE, ESCOT) and related issues (IMS, XML) • Learning appliances • Networked improvement communities
Concord Consortium
Center for Innovative Learning Technologies http://cilt.org
Social networking apps (ICQ) • 20 million users as a free web-based technology • Provides instant messaging and chat between online users, and enables URL transfers, file exchanges, online gaming • Sold to AOL for $287 million in June98 • Like HotMail (Microsoft purchase), enables an ‘aggregation play’
Social Information Filtering • “Automated word of mouth” concept • 8-10 different companies including NetPerceptions’ GroupLens, Firefly, Alexa Internet, LikeMinds • Example: amazon.com book and music “recommender systems” • Extensions with profiling for educators • “1:1 marketing” (pros and cons)
Educational object economies • Distributed educational component software libraries for re-use • EOE • ESCOT • IMS • XML
Example:Educational Object Economy • Created by Jim Spohrer, et al. (Apple) • Now a non-profit organization • Building a sustainable community of small developers producing free educational applets (over 3000) http://www.eoe.org
ESCOT (Educational SoftwareComponents of Tomorrow)* A distributed network of teachers, researchers & developers creating link-able representational tools for real middle school math curricula. *A new NSF grant (Pea, Roschelle, Kaput and DiGiano)
Distributed Intelligence: Role of components • Graphs, tables, calculators, geometry, simulations, equations, notepads… probably 100 or so core active representational objects that occupy parts of a screen • Enable mix-and-match, plug&play • Cognitive research rationale: • Dynamic, linked multiple representations key for deeper understanding • Animated graphics for process history • Collaboration support • Assessment support • Leading to: • • Lower cost • Better quality • More flexibility
Geometer’s Sketchpad ESCOT • Goals • Collect broadly useful, powerful components • Link to curriculum needs • Combine in new activities • ESCOT Teams Integrate Re-usable Components from a Shared, Web-Accessible Library into Lessons • Teacher: Pedagogical Design • Developer: Component Design • Web facilitator: Web Design (and teamwork)
Learning appliances • Palm Pilot hits the “form-function” sweet spot (63% global market) • 10,000 developers, serious OS • Examples: Probeware, MathWorlds • Dubinsky-Hawkins new company: Handspring (retail consumer market)
Fastest adopted HH computing device of all time Over 2 million
HandSpring (Post-Palm Computing) • "We believe the handheld computing business will be quite a bit bigger in unit volumes than the PC market, and looking at the possible growth areas, we think one of them is consumers -- individual purchasers spending their own money," said Ed Colligan, vice president of development and marketing at Handspring. (Nov 5, 1998, WiredNews)
Networked improvement communities • Doug Engelbart’s work as context • Example: Tapped In • ESCOT • CILT • PALS
SRI’s TAPPED IN Project(http://tappedin.sri.com) • SRI International -- Center for Technology in Learning (Mark Schlager, Patricia Schank, Judith Fusco, Richard Goddard) • Partners are twelve K-12 teacher professional development organizations devoted to science educational reform • Goal: to develop, operate and study an easy-to-learn, multi-user virtual environment for ongoing teacher professional development • In 19 months: over 2000 registered users already • 1996-2000 Funding:
