content

Our lives are becoming increasingly dependent upon computers, creating opportunities and challenges in disciplines as diverse as cognitive science, economics, and medicine. This half-credit course is a fast-paced introduction to the field of computer science. We will explore computer problem solving and programming techniques through lectures and labs using the C++ programming language. The weekly programming labs will build upon previous ones, employ important computer science algorithms, and lead to the construction of a class-wide project. No prior programming experience is required for this course, only a sincere interest in learning about computer science.

course policies

textbook

There is one required textbook for the course, which is available as a course pack at Gnomon Copy, 348 Boston Ave.

• Allen B. Downey, How to Think Like a Computer Scientist: C++ Version, Green Tea Press, 1999.

Students should bring their books to the lab sessions.

grading

Approximately:

• 65% Assignments
• 25% Final project
• 10% Class participation

All lab assignments will be turned in electronically and are expected to be completed by their due dates. Late assignments will be penalized at 10% per day. Any assignment turned in more than one week after its due date will receive a zero grade.

Please read the Dean's booklet on academic integrity.
