Why Teach CS in High School? n Computer science knowledge is important n n Jobs are plentiful, interesting, and flexible n n Required for many fields: business, math, science 5 of the fastest growing jobs 1. 5 million jobs by 2016 High starting salaries Students learn 21 st century skills n Critical thinking, problem solving, teamwork
CS is important for business Walmart n Has a large data warehouse and uploads the data from each store every night n Knows what products are selling at what stores n Can plan future sales based on past data Kmart n n n Didn’t update its computer systems Didn’t create a data warehouse with data from all the stores Went bankrupt in 2002
What is CS? n n n Computer science is the study of computers and algorithmic processes, including their principals, their hardware and software designs, their applications, and their impact on society. (ACM Model Curriculum) Computer Literacy: using software applications Educational Technology: The use of computers to support learning
CS Includes n n n Programming Theory Artificial Intelligence Databases Networking Information Security Human-Computer Interfaces Graphics Simulations Software engineering Web science Robotics
C. S. in U. S. High Schools n Mostly computer literacy classes n n n Most schools do not offer computer science n n n Keyboarding and applications Some web design and networking 25 states have never had more than 100 students take the CS AP A exam CS courses are elective Most teachers have no formal training in computer science
AP CS versus other exams: US
CS AP A in the US 2009 n Best states by # exams / population 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Maryland Texas Virginia New Jersey Washington D. C. Connecticut Massachusetts Georgia California New York
C. S. in other countries n n Many have rigorous computing classes Computing is required to graduate from high school n n In 20 EU countries plus Bulgaria, Iceland, Liechtenstein, Norway, Israel, and Romania Teachers have formal training in CS n n Scotland requires qualifications to teach CS Israel requires a degree in CS
Computing Courses n ACM Model Curriculum for K-12 Education n n Level I – K-8 Level II – 9 th or 10 th grade Level III – 10 th or 11 th grade Level IV – 11 th or 12 th grade
High School Curriculum ACM Model Curriculum Level 2 (II) Computer Science in the Modern World Level 3 (III) Computer Science as Analysis and Design Georgia Curriculum Level 2 (II) Computing in the Modern World Level 3 (III) Beginning Programming Level 3 (III) Intermediate Programming Level 4 (IV) Topics in CS – Advanced Placement CS
