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 educationbased on
– Connexions: open access e-textbook system
– Lablets: interactive visualizations and simulations
– Q/A database: for assessing student learningprogress
2.A growing community of concerned SP educators
supported by the NSF CI-Team program

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
• 55 faculty adoptions across USA in 2010
• 6 customized versions in CNX
• Approved by California Free Digital Textbook Initiative (met 19/19 standards)
free online: 2 million uses to date

interactive lablets
• Interactive simulations that enhance learning and teaching
• Enable learning to visualize, process, and interact hands-on
• Encourage exploration of SP topics
• Make abstract ideas more concrete
• Easily integrated into Connexions
• Easy to develop using LabVIEW, Mathematica, Matlab, JDSP, …
Q/A Databases
James McClellanGeorgia Institute of Technology
Q/A databases
• Signal Processing Question and Response (SPQR) system at Georgia Tech: over 1200 solved problems
• Question/Answer data base (QuADbase) at Rice
• QTI markup compatible with learning management systems and Connexions
• Track student performance through courses and across curricula
• Under development: SP intelligent tutoring system
