AP Computer Science Principles Curriculum/Content Area: Computer Science Course Length: 2 Terms Course Title: Advanced Placement Computer Date last reviewed: November 2019 Science Principles Prerequisites: none Board approval date:TBD Desired Results Course description and purpose: The Advanced Placement Computer Science Principles course provides students with the opportunity to develop computational thinking skills, an understanding of the real-world impact of computing, and programming literacy. The course exposes students to the breadth and relevance of computer science across many fields of study that incorporate computer science knowledge. A strong focus on creativity as it applies to the creation of computational artifacts allows a broader range of students to discover where computer science could fit in their lives, and it prepares more students for success in computer science and other related STEM fields. Enduring Understandings (EUs): Essential Questions (EQs): 1. Creative development can be an 1.
