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

our response Signal Processing Education Network (SPEN) 1.A new framework and platform for SP education based on –Connexions:open access e-textbook system –Lablets:interactive visualizations and simulations –Q/A database:for assessing student learning progress 2.A growing community of concerned SP educators supported by the NSF CI-Team program
