2. crises in SP education • Sequential and inflexible textbooks • sequential presentation misleads and bores students • current textbooks not customizable • Static and inefficient content development models • textbooks and other learning materials take years to develop and get to market • Passive student experience • studies show most undergraduates passively listen, transcribe, absorb, and repeat in course after course • Missing components • most textbooks do not have enough support material to reach diverse audiences • Inaccessible • textbook costs rising 2-4x faster than inflation

3. our response Signal Processing Education Network (SPEN) • A new framework and platform for SP educationbased on • Connexions: open access e-textbook system • Lablets: interactive visualizations and simulations • Q/A database: for assessing student learning progress • A growing community of concerned SP educatorssupported by the NSF CI-Team program

6. open educational resources • The Open Educational Resource (OER) movement was inspired by the Open Source movement in software • Information is freely usable, re-usable, re-mixable, modifiable, etc. • Creative Commons license makes content both safe and easy to share

8. Connexions (cnx.org) • Non-profit educational platform founded in 1999 • Innovative authoring and publishing environment • All materials free on-line (web, PDF, ePub for iPad) • All materials low-cost in print • Modular: 1000 e-textbooks built from 17000 modules • Worldwide usage: 2+ million users per month • Content and translations in 40+ languages

10. books vs. on-line use Books from Connexions: • Personalized, on-demand printing, up-to-date, inexpensive, collaboratively authored, allows pre and post publication review, never “out of print”, “Long tail” publications, content for eBooks, one button to buy printed book On-Line use of Connexions: • Allows modern pedagogy: concept-based, problem solving-based, discovery-based learning. Dynamic, interactive, linked, adapts to learning style, student and author driven, allows “assessment and evaluation”, Virtual Labs
