Book Description

With Scratch 2.0, getting started in computer programming is easier and more fun than ever. And with this completely updated edition of the popular Scratch Programming for Teens, you'll learn the basics in a fast, friendly way and be sharing your creations online before you know it. Focused on the fundamentals and using the free Scratch programming language, Scratch 2.0 Programming for Teens will teach you to develop interactive stories, games, animations, and other programs on the web, in your computer's browser, using graphic, customizable code blocks. Written especially for first-time programmers, it emphasizes the design and development of programming logic. You'll learn important programming concepts without getting bogged down in complicated details. And the basic principles you learn here will build a foundation from which you can move on to other, more complex, programming languages (like Microsoft Visual Basic, Java, and C++), if you decide to go deeper into software development. Additional material, including helpful appendixes and a complete glossary, is available on a companion website. Start programming today with Scratch 2.0 Programming for Teens. Scratch is a project of the Lifelong Kindergarten group at the MIT Media Lab. Scratch, the Scratch logo, and the Scratch Cat are trademarks of the Massachusetts Institute of Technology.
