National Trends – Number of newly declared CS majors nationwide Source: 2005 -6 Taulbee Survey

National Trends • • The % of female Bachelor’s degrees went from 17. 0% in 2003 -04 to 14. 7% in 2004 -05. . . In 2005, less than 7% of CS degrees were awarded to Hispanic and African American students.

National Trends Why is this a problem? “Computer Science is the mathematics of the 21 st Century. ” Jim Gray

Solutions Broaden the image of who can do CS Broaden the image of the field of CS

Solutions Introduce Depth and Breadth of CS into the Curriculum Computational. . . • Problem Solving Biology, Chemistry, • Programming Design, Finance, Linguistics, • Algorithms Logic, Mechanics, Neuroscience, Physics, . . . • Biology/Neuroscience + CS • Graphics: Art, Animation + CS It appears that our • K-12 students Interaction know Human Computer need to • Language more than how to think computationally Technologies ever before! • Artificial Intelligence + CS • Robotics

CS 4 HS: Our Focus • Computer science is much more than computer programming. • We can do little to change AP Computer Science in the short term, so let's provide short modules about computer science for CS teachers to use in their classes. • Teachers can then show their students (and future students) that CS includes programming and SO MUCH MORE. • By teaching the teachers, we can reach many more students than by working with the students directly. Think Global, Act Local, Impact Global

Participants • Level – High School 41 (Depts: CS, Math, Tech. , Business) – Middle School 4 – College/University 7 • Areas represented: – United States: PA, OH, WV, MD, DE, VA, NY, NJ, IN, IL, KY, TN, AZ, CA, CO, WA, TX, FL, MA, NH, WI – International: Canada, Mexico, India • Role of CS in high school education in their state Elective 65% Must be taken 2. 5% Use as a substitute 10% No idea 22. 5%

Perceptions • In your opinion, what is the biggest cause of enrollment decline in CS in the past decade? Bust of dot coms No standard curriculum NCLB Courses too hard Elective status Isolated teachers No CS in middle school Antisocial/geek culture Hard work, less pay Boring CS treated as a vocation What can you do with it? Students think CS = internet, Word Uninformed teachers/administrators Too many required courses Media reports/Offshoring Competes with easier electives Not "sexy" enough to keep their interest Not relevant to students Fracture of fields (CS, IS, Soft Eng, etc) Too exclusionary No state certification for teachers

Ed Lazowska University of Washington

Philosophy • Success in high school math and science (and English!) is a better predictor of success in CS than is success in high school programming • Many members of under-represented groups never take programming in high school Target teachers of math and science • Most colleges and universities – even excellent ones – draw regionally, not nationally – 85% of UW’s freshmen are from WA – Nearly 1/4 come from just two dozen high schools! Target a regional audience

Participants • 72 teacher-registrants – All from the Puget Sound region • 22 stayed in dorms, 50 commuted – Recruited via email • UW math and science department lists of teachers and groups • AP teacher lists • Principals and department heads at top feeder schools • 10 speakers – Mostly local, but some traveled

Schedule highlights • Presentations – – “Computational Thinking” – Jeannette Wing “The Computer Revolution Hasn’t Happened Yet” – Alan Kay “Biology & Computer Science” – Tom Daniel “Computer Science at UW” – Ed Lazowska • Lab sessions – “Squeak in Action” (Squeak programming) – Stuart Reges – Robotics (Lego Mindstorm) – Benson Limketkai – Programming (two tracks, for those with programming experience, and those without) – Stuart Reges, Marty Stepp

Schedule highlights • Interactive sessions – “Cryptography Made Easy” – Stuart Reges – “CS Unplugged” (2 sessions) – Tom Cortina – Demos: motion capture, educational technology, computing for the developing world – “Computing Careers” panel – Two “Break-out by Subject Taught” sessions, plus a reportback session (how to apply what you’ve learned in the course you teach) – Book discussion (3 break-out groups, for. The Search, Unlocking the Clubhouse, and Cryptonomicon) • Closing banquet

Logistics • 3 full days • Required $25 registration (as a sign of commitment) • Provided “Squeakers” DVD, Amazon. com gift certificate for book (cost $3 K) • Granted 20 clock-hours or 1 unit of UW credit ($3 K) • Provided dormitory accommodation for 22, parking for 50, travel and hotel for non-local speakers ($8 K) • Provided breakfast, lunch, snacks on 3 days ($6 K) • Closing banquet was way too expensive ($13 K) • Grad student organizer (Julie Letchner) – lifesaver! ($8 K)

Plans for 2008 • Same idea, with minor tweaks • Will produce “logistics manual” • http: //cs 4 hs. cs. washington. edu

CS 4 HS at UCLA

Future Plans • Summer Workshop – July 24, 25, and 26 th at UCLA • Continue working with Tim Bell and Computer Science Unplugged • Partner with Jane Margolis and others working with LAUSD and schools within LA and Orange Counties • Continue to plan three workshops/year to support CS faculty and IT coordinators

CS 4 HS is expanding! • Our newest CS 4 HS team member! University of Texas at Austin First Bytes Collaborative Workshop for Computer Science Teachers

2008 Workshops • Carnegie Mellon University July 24 -27, 2008 • University of California, Los Angeles July 24 -26, 2008 • University of Texas at Austin ("First Bytes") July 9 -11, 2008 • University of Washington July 11 -13, 2008

Goals • Expand to 40 workshop sites in the next two years. • Reach out nationally and internationally. – At least one workshop on each continent outside of N. A. • We need your help to make it a success! – Run a workshop or join forces with a larger CS department nearby. – Determine the special needs of your area and use your in -house expertise to craft a workshop that will support the teachers in your area.
