The Expansion of CS4HS: An Outreach Program for High School Teachers:

The Expansion of CS4HS: An Outreach Program for High School Teachers Lenore Blum, Carnegie Mellon University Tom Cortina, Carnegie Mellon University Ed Lazowska, University of Washington Joe Wise, New Roads School for UCLA

National Trends:

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

National Trends:

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:

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

CS4HS: Our Focus:

CS4HS: 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

Tom Cortina Carnegie Mellon University SCHOOL OF COMPUTER SCIENCE


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% Use as a substitute 10% Must be taken 2.5% 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 What can you do with it? No standard curriculum Students think CS = internet, Word NCLB Uninformed teachers/administrators Courses too hard Too many required courses Elective status Media reports/Offshoring Isolated teachers Competes with easier electives No CS in middle school Not "sexy" enough to keep their interest Antisocial/geek culture Not relevant to students Hard work, less pay Fracture of fields (CS, IS, Soft Eng, etc) Boring Too exclusionary CS treated as a vocation No state certification for teachers


Schedule/Topics FRI SAT SUN MON Morning 9-12:30 CS Unplugged and Keynote (Alan Kay) Cybersecurity and Bots N Scouts tournament Cognitive Tutors and Brainstorming Lunch at Google Pittsburgh Box Lunch (Free Time) Afternoon 2-5:30 Cake Cutting & Broadening Participation Panel TeRK Robots and Careers in CS Panel Dinner (Free Time) Pizza Party Evening 7:30-9 Dinner & Icebreaker Human Computation Intro. to Alice


Logistics Professional Development Credits In Pennsylvania, teachers receive Act 48 credits for each hour of instruction/participation Other teachers received certificates with the number of hours served to use in their home state for credits Major costs Housing: $10K Food: $6K Materials: $5K Outside Speakers: $2K Documentation (Photography, videography): $4K Administration, summer salary: $8K

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:

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 report-back 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 Schedule highlights


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

CS4HS is expanding!:

CS4HS is expanding! Our newest CS4HS team member! University of Texas at Austin First Bytes Collaborative Workshop for Computer Science Teachers

2008 Workshops:

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.
