"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

or... Should I Take This Course?

This course is an introduction to the field of Computer Science. It 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 science student such as tools and terminology. Developing introductory programming skills will be a major part of the course. Since the course is about computational thinking and you will have to think, problem solve, and practice skills both in the class and on your own... a lot. You should plan on a minimum 3 hours outside of class for every hour in class.

Everyone is welcome to take this course, whether you are going on in computer science or not. However, this course has a specific audience in mind. This course is NOT FOR PEOPLE who have had nontrivial programming experience in a language such as C, C++, Python, Java, JavaScript, PHP, Lisp, etc. Also, you probably should not be in this course if you are currently taking calculus or higher level math. In these cases you should probably be enrolled in CS120. Furthermore, this course has a lot to do with procedural and symbolic abstraction. If you have trouble with algebra you might want to allow extra time for homework or consider waiting until you have a stronger grasp of algebra.

This course is for you if you would like a comfortable, relaxed, and fun beginning course in computer programming. Also, if want to understand a bit better about the future of the world you live in this is it.

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 give you confidence in the deep technical side of computers. But this course is not trivial. You have to think. Many people flunk this course. Be prepared to work.

This course is not about how to use applications like Word on a computer! It is how to begin to bend a computer to our will by designing and writing programs.

NOTE: if you have already taken CS120 you will NOT get credit for this course on your transcript!

Class Support

These are resources for help if you are having problems with anything in the course:
  • CSAC Schedule (coming soon). CSAC is the Computer Science Assistance Center and is staffed with people to help. They are now located in JEB 211. I will post here the hours of someone that is specifically knowledgeable about CS112.
  • A free recitation section is available for this class to give extra help explaining material, practice for homeworks and exams. It is in ED 243 hours: T 3:30pm-4:30pm, W 6:00pm-7:00pm, F 3:30pm-4:30pm.
  • My office hours are a time you can drop by and ask questions or bring up concerns. They can be found in my schedule and unfortunately may change as the semester progresses: My schedule

  • For each assignment follow the instructions for that assignment for where to turn in the work. Wait for each assignment to be assigned before starting work on any assignment. Assignments will be announced in the class news and posted in the assignment schedule when the assignments are made.
  • For most assignments use homework submission page to submit you homework unless otherwise instructed. Your name is your UI mail id (usually 4 letters followed by 4 digits). Note: it will ask you to log in. Be sure you get the success message after hitting the submit button. If you don't get the success message with a time stamp you have not submitted your homework. If your file is not the right type of file it will return an error. Within ten minutes it should mail you at your university email address with a simple confirmation message.
