|Method of Instruction - |
- Lectures which include motivation for syntax and use of the Unix Operating System shell programming, example programs, and analysis of these programs.
- On-line labs (for all sections, including those meeting face-to-face/on campus) consisting of
- A programming assignment web-page located on a college-hosted course management system or other department-approved Internet environment. Here, the students will review the specification of each programming assignment and submit their completed lab work.
- A discussion web-page located on a college hosted course management system or other department-approved Internet environment. Here, students can request assistance from the instructor and interact publicly with other class members.
- Detailed review of written assignments which includes model solutions and specific comments on the student submissions.
- In person or on-line discussion which engages students and instructor in an ongoing dialog pertaining to all aspects of designing, implementing and analyzing programs.
- When course is taught fully on-line:
- Instructor-authored lecture materials, handouts, syllabus, assignments, tests, and other relevant course material will be delivered through a college hosted course management system or other department-approved Internet environment.
- Additional instructional guidelines for this course are listed in the attached addendum of CS department on-line practices.
