The year in review: changes and lessons learned in the design and implementation of the AP CS exam in Java

The 2004 school year marked significant changes in the Advanced Placement (AP) Computer Science curriculum. Most visibly, Java replaced C++ as the exam-testable programming language. More fundamentally, however, the AP CS curriculum now places a greater emphasis on object-oriented design than in previous years. Students are expected to be able to implement interfaces, design and implement class hierarchies using inheritance, analyze the tradeoffs between alternative designs and their associated efficiencies, and make use of Java Collection classes where appropriate. This special session is intended to inform both high school and college teachers as to the extent of these changes and how they affected the development and grading of the 2004 AP CS exams. In addition, it will provide practical insights as to how the new curriculum can be taught in high schools, and how teachers can better prepare their students for the exams.The AP CS Development Committee's charge is not only to provide a comprehensive testing mechanism, but also to recommend a direction that high school teachers should take in preparing a foundation for more advanced student studies during college. This special session will bring together two college and two high school members of the AP CS Development Committee to share some of their insights into the AP program.AP teachers will learn valuable information to continue to support their shift to Java in the classroom and about the exam for which they are preparing their students. College teachers will learn more about the AP CS curriculum and test development process, which may aid them in similar course redesigns and in the placement of students with AP credit.Time will be provided to discuss participant's questions.
