Upper School Curriculum Guide

The world continues to be more and more reliant on computers and computing innovations to function. Our daily reliance on our smartphones and the Internet are just two small examples. Fields as disparate as biology, fashion, agriculture, and finance are impacted daily by computer innovations, and to function in this cyber-connected economy, students must be literate in the field of computer science.

The Computer Science Department offers courses in both computer programming as well as design and engineering. Our programming courses teach students how to code and how computers work. They also discuss how computing innovations can impact our society, economy and culture. The design and engineering courses teach students about the ways in which design and technology intersect, and offer hands-on applications so that students might learn about the many applications of computing in the physical world.

All students are required to pass one half unit course in Computer Science before graduation. Students may choose the course that best suits their interests and comfort with Computer Science in order to meet this requirement. We encourage students to speak with members of the Computer Science department in order to choose the appropriate course.
 

COURSE SELECTION GUIDELINES

The Computer Science course offerings are all electives. Most students will begin with Introduction to Computer Science, Computational Biology, or CS Exploration and Creative Computing. If a student has previous experience in programming, or has taken other computer science or programming courses, the student should explore the curricular sequence for computer science and see the Department Chair to discuss placement options.

For AP and Advanced courses in computer science, please watch RCDS News for the online sign-up forms and direct specific questions to the Department Chair.

AP HOMEWORK GUIDELINES

AP Computer Science A: Students spend an average of 30-45 minutes each night on homework. Students have a summer requirement to complete online.

AP Computer Science Principles: Students spend an average of 20-30 minutes each night on homework. There are two large projects to submit to the College Board, which include writing.

DEPARTMENTAL POLICIES REGARDING ENTRY INTO AP COURSES

AP Computer Science Principles focuses broadly on programming in multiple languages, creatively expressing and writing about the impact of computer science on our world, and would be equivalent to a college level introductory computer science course for non-majors. If planning to take both AP courses, AP Computer Science Principles is the recommended first course, but they may be taken in either order.

AP Computer Science A focuses entirely on programming, particularly in Java, and would be equivalent to a college level introductory computer science course for computer science majors. Students must receive approval from the department, earn an A- or better in Introduction to Computer Science, or complete AP Computer Science Principles before enrolling in this rigorous course.
