Blocks can only be stacked if they fit together. "They don't have to worry about the obscure punctuation and syntax common in most programming languages," he said.Įach block contains a separate command, such as "move" or "play drum" and each action can be modified from a drop-down menu. Objects and characters, chosen from a menu and created in a paint editor or simply cut and pasted off the web, are animated by snapping together different "action" blocks into stacks. "Kids make programs by snapping blocks together," said Professor Resnick, whose position is in part supported by the toy company. The program works by making the act of creating a computer program more like building with Lego bricks. We want them to create interesting dynamic things on the computer." "With Scratch we want to let kids to be the creators. "These days, kids interact with all kinds of dynamic things on screen but it is usually a one-way street - they are usually interacting with things that other people have created," said Professor Resnick, who also invented Lego Mindstorms, a robotics toolkit often used in teaching. The explosion in broadband connectivity has fuelled the growth of websites that offer rich media experiences, including video and animations. "We have developed Scratch as a new type of programming language, which is much more accessible." "Computer programming has been traditionally seen as something that is beyond most people - it's only for a special group with technical expertise and experience," said Professor Mitchel Resnick, one of the researchers at the Lifelong Kindergarten group at MIT. The digital toolkit, developed in the US at MIT's Media Lab, allows people to blend images, sound and video. Instead, it uses a simple graphical interface that allows programs to be assembled like building blocks. Primarily aimed at children, Scratch does not require prior knowledge of complex computer languages. Scratch's creator Mitchel Resnick building a characterĪ free programming tool that allows anyone to create their own animated stories, video games and interactive artworks has been developed.
