A set of instructions is called a program. The, instructions are written in what’s known as a programming, language, and there are thousands to choose from., , Scratch is a programming language that is perfect for making, games, animations, interactive stories and other visually rich, programs. It provides a great introduction to programming for, people of all ages. It’s widely used in schools and colleges, but, Harvard University has also used it in higher education at its, Summer School. I've led workshops for adults where Scratch, provided a friendly introduction to the kind of creative problem, solving that programmers do all the time., , Scratch is easier to use than most other programming languages, for a number of reasons:, , ©@ You don't have to remember or type any commands: they're, all on screen, so you can just drag and drop them., , @ Commands fit together like jigsaw pieces, so there are strong, visual hints about how you can combine them., , @ Error messages are rare. Because Scratch commands lock, together, programs always make some kind of sense. It is, possible to still write programs with logical errors in, if they, don't do what you expected, but Scratch guides you to write, things that work, rather than nagging you when they don't., , © The commands are color-coded and categorized, so you can, easily find a command when you need it., , @ The commands in Scratch simplify common activities in, games, such as testing whether a missile has hit an alien, (collision detection), or rotating a character on screen., , In short, Scratch is designed for your success. It enables you to, quickly see results from your work, and even includes graphics, and sounds you can use so you can get started right now. Many, other programming languages require you to learn text commands,, and strict rules about how you can use them. Scratch doesn't., , ‘That means you can focus your energy instead on the fun stuff:, dreaming up ideas for new programs, working out how to build, them, designing them, and sharing them with friends.
