Why Teach CS in High School? Computer science knowledge is important

Required for many fields: business, math, science

Jobs are plentiful, interesting, and flexible 5 of the fastest growing jobs 1.5 million jobs by 2016 High starting salaries

Students learn 21st century skills Critical thinking, problem solving, teamwork

CS is important for business

Walmart Has a large data

warehouse and uploads the data from each store every night

Knows what products are selling at what stores

Can plan future sales based on past data

Kmart 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? 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 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 Mostly computer literacy classes

Keyboarding and applications Some web design and networking

Most schools do not offer computer science 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 Best states by # exams / population

1. Maryland2. Texas3. Virginia4. New Jersey5. Washington D. C.6. Connecticut7. Massachusetts8. Georgia9. California10. New York

C.S. in other countries Many have rigorous computing classes Computing is required to graduate from

high school In 20 EU countries plus Bulgaria, Iceland,

Liechtenstein, Norway, Israel, and Romania Teachers have formal training in CS

Scotland requires qualifications to teach CS Israel requires a degree in CS
