The Problem Nationwide

US Dept of Labor predicts the fastest
growing occupations in 2002-2012
• Computer Software Engineers
• Computer System Designers

Across the county the number of CS
students is dropping (23%)
• Some high schools are removing CS
• Percentage of women is in teens
• Several groups are underrepresented
The Problem in Georgia

Only about 50 schools of over 370
public schools offer AP CS
• Many of these are private schools

Many students don’t take the exam
• Many of the ones who do, don’t pass

AP CS moved to Technology and
Career Education Department
• Most of these teachers have no
programming experience
One Solution

ICE: The Institute for Computing
Education
• Partnership between



Georgia Tech’s College of Computing
Georgia Department of Education
Announced June 2004 by Kathy Cox
and Richard DeMillo
ICE History

November 2003 Diversity Advisory
Board meeting
• Nationally recognized professionals

From academia and business
• Including the Director of Technology and
Career Education in Georgia

Discussions of the problems with CS
and how to solve them
• Led to the formation of ICE
ICE Goals

Train more CS-AP teachers
• Start by training teachers for an
introductory course

even teachers with no experience
• When ready train for CS-AP course

Increase the number and diversity of
CS students
• Interesting curriculum
• Help with recruiting
Summer 2004

1 week AP workshop
• 17 teachers attended

2 week Programming and Systems
Management Workshop
• 30 teachers attended

Two 1 week summer camps for high
school students
• 30 students each week
AP Workshop
AP Workshop Development

Development
Process
• Visits to classrooms
• Teacher surveys

Desired Content
• Object-oriented
principles
• Case Study
• Data Structures
AP Workshop Content

Short lectures (< 30 minutes)
• Followed by hands-on activities






Role-playing
OO Analysis using CRC cards
UML class diagrams
Small programming assignments
Demonstrations of current research
Talk on encouraging diversity
Prog and Sys Workshop
Prog and Sys Development

Adapt curriculum from undergraduate
course for non-majors at Tech
• Taught in Python
• Developed by Mark Guzdial

Teaches CS by manipulating media
• Pictures, sounds, movies, text

The undergrad course has been successful
• Better retention rates
• Attracting more women and underrepresented
groups
• Getting people to transfer into CS
• Students are taking a second CS course
Prog and Sys Content Delivery

Short Lectures (< 30 minutes)
• Hands-on programming assignments
• Role playing

Demos of current research
• Robot dogs, aging in place


Talk on diversity
Student panel discussion
Prog and Sys Content










Introduction to object-oriented concepts
Keywords and operators
Primitive and object variables
Class and object methods
Arrays
Iteration (for and while loops)
Conditionals (if, if-else, if-else-if, and, or)
Graphical User Interfaces
Input/Output and Exceptions
Debugging
Goals for Content

Motivating
• For students and teachers

Creative
• Open-ended assignments

Authentic tasks
• Start with what students use computers
for (pictures, sounds, text, web, games)
Negate an Image
Mirroring
Rotation
Create a Collage
Remove ‘Red Eye’
Sepia-Tint
Chromakey
Teacher Collages

Quotes




I didn’t want to take this workshop. I
thought it would be boring and too mathbased, but I am having fun.
My kids won’t believe that I am
programming for fun.
This was the best (non-college credit)
workshop I have ever taken.
The demos were awesome. I wish I had
thought ahead & had a video camera to
record demos.
Student Summer Camps

Two one-week summer camps for high
school students
• Not residential
• 30 students in each camp

Content

What Else is ICE Doing?

Winter/Spring 2-day Workshops
• AP Case Study
• Teaching Java using Turtles, Robots, and
Sound
• Preparing for the AP Exam

AP Bowl Competition at Tech
• April 16th

Developing a database of practice exam
questions and answers
• With explanations for all answers
Extending the Case Study
Using Turtles, Robots, and Sound
to Teach Java




Use LEGO Robots and a visual
programming language to introduce
programming concepts
Use Turtle.java to control a virtual
turtle using Java
Use Karel J. Robot to control a virtual
robot using Java
Use Sound manipulations to teach
programming concepts
LEGO Robots
RCX Code Visual Prog Language
Program a Turtle with Java
Program a Robot with Java
Using Sound to teach Java

Write programs to reverse a sound,
append sounds, make a sound clip,
and construct a MIDI song

Model for Others


Partnership between a Dept of
Education and a University
Summer workshops and camps
• With year-long follow-up for the
teachers

Can grow new CS-AP Teachers
• Even from teachers without much
programming experience

Have teachers signing up for this summers
AP workshop
Challenges

Funding
• State provides some funding

For workshops
• Georgia Tech would like more support


From NSF, corporations, or foundations
Managing Expectations
• Don’t we have more AP teachers yet?
• 3-5 year time frame for results
