Welcome to CSE 121: Introduction to Computer Programming I πŸŽ‰

What is this class? What will I learn?

Computing continues to play an ever-increasing role in today’s society. Having an understanding of computing is an essential skill for those in the 21st century; from working in industries more reliant on technology, using computational methods to further scientific understanding, or being an informed citizen in a world with technology all around us.

This course is a first course in computer programming focused on the basics of procedural programming in Java. It assumes students have not taken a previous programming course and do not have substantial other programming experience. (Students with previous experience are encouraged to consider CSE 122.)

Prior Experience and Expectations

This course is intended for students who have no or very little previous programming experience. CSE 121 will teach the fundamentals of programming in Java from the very beginning. If you have previous programming experience in any text-based programming language (Java, Python, Javascript, etc.), you may find that CSE 122 or another course is a better fit for you.

To help assess if CSE 121 is the right class for you, the Allen School has developed a Self-Guided Placement to help students assess which intro course is the right one for them to enroll in. Please see this website for more information on who to contact if you have questions about which introductory CSE course is the right course for you.

Feedback

Feedback is always welcome! You can contact the the course staff or submit anonymous feedback.

Info

This is a rough sketch of the quarter and things are subject to change. We can accurately predict the past, but predicting the future is hard!

Lessons

Anything listed in the “Lesson” materials for a day should be read before attending class that day. The Lessons are a first introduction to the most important terms and concepts for that day of class. It is okay if the Lesson doesn’t make complete sense as we have the rest of the class day to clarify the concepts, but if you don’t do the Lesson the class session won’t make any sense.
