In this introductory course students enter the world of computer science by learning how to create animations, computer games, and interactive projects. Using Scratch, a graphical programming language developed at MIT, students learn fundamental programming concepts such as variables, loops, conditional statements, and event handling. The course will show students how to make and import objects, create audio recordings, and use them to develop interactive projects. At the end of the course, students create their own computer game and share it with their instructor and classmates. No previous programming skills are required, but students should be comfortable using a computer and browser, and managing files.
