"Computers are dull and boring; humans are clever and imaginative. We humans make computers exciting. Equipped with computing devices, we use our cleverness to tackle problems we would not dare take on before the age of computing and build systems with functionality limited only by our imaginations." -- Jeannette Wing

Course Description

This course is nearly identical to CS112. This is the FAQ for CS505. It can be used as:

  • professional development course for understanding the very most basic ideas of computer science.
  • to prepare to teach CS112 as a Dual Credit course.
  • as the first course in a series courses (20 credits total) to gain a Certificate in Computer Science Education through the University of Idaho leading to a teaching endorsement in Computer Science.
It is presented as a live video course via Zoom. We will be live at our Coeur D'Alene campus and Idaho Falls video classrooms. Zooming with personal laptops by request to the instructor.

Specifically, this is an introduction to the field of Computer Science. Some discussion of how this material could be presented in a K-12 setting will be discussed including the future of Computer Science education in K-12. Computer Science content will cover the breadth and impact of computer science on society; and what it means to be a computer scientist. A large portion of the class will be devoted to introducing the major concepts of computer science, and the background needed to be successful as a computer scientist such as tools, terminology, and introductory PROGRAMMING SKILLS. You will have to think, problem solve, and practice skills in this class.

One way to introduce Computer Science is by learning to program. All of the assignments will be programming assignments in a variety of computer languages of varying complexity, hopefully in an entertaining way. This course is for people who have little to no programming experience. It should comfortably give you confidence in the deeper technical side of computers. This course is not about how to use applications on a computer! It is how to begin to bend a computer to our will by designing and writing programs.

Time: MWF 4:30-5:30 PT
Final: None (see testing schedule)
Location: EP 204 Moscow Campus (Zoom Video Live, also in CDA and IF video classrooms.)
Text: None (see the resources section throughout the semester)

Estimated Syllabus

This syllabus is an estimate of what we might cover this semester. The class varies from semester to semester to reflect new and interesting topics and the rate at which the class is absorbing material.
