Some of the required work for this course, most notably the team project, is naturally collaborative in nature. However, since your grade for the course is based on your individual performance, it is both ethically responsible and prudent to cite and acknowledge the work of each of the contributors to a collaborative project and to allocate credit accurately.
Both collaboration and the use of outside work are prohibited on the first programming exercise, which is partly diagnostic in intent. The work you submit on this exercise must be entirely your own.
When submitting written work, you must also cite and acknowledge any external sources from which you have derived ideas, text, images, program code, etc., as described in the section on “Honesty in written work” in the Student Handbook.
If I encounter clear indications of plagiarism, the Committee on Academic Standing will deal with them. The College's policies for faculty members, which I support enthusiastically, prohibit me from trying to investigate such matters and from imposing any penalties for academic dishonesty on my own.
