![]() ![]() User-defined functions, accessible as blocks. ![]() Cloud variables can be accessed by all running versions of the project. Sprites can interact with other sprites, the mouse pointer, and the backdrop.īlocks to access and set variables. Movements of sprites like angles and directions. The table below shows the categories of the programming blocks: When creating sprites and also backgrounds, users can draw their own sprite manually, choose a Sprite from the library, or upload an image. The Sounds tab allows attaching sounds and music to a sprite. The Costumes tab allows users to change the look of the sprite with a vector and bitmap editor in order to create various effects, including animation. With a sprite selected at the bottom of the staging area, blocks of commands can be applied to it by dragging them from the block palette into the coding area. The stage uses x and y coordinates, with 0,0 being the stage center. The stage area features the results (e.g., animations, turtle graphics, either in a small or normal size, with a full-screen option also available) and all sprites' thumbnails being listed in the bottom area. Users may also create their own code blocks and they will appear in "My Blocks". The Scratch interface is divided into three main sections: a stage area, block palette, and a coding area to place and arrange the blocks into scripts that can be run by pressing the green flag or clicking on the code itself. Scratch 3.0 User interface A program to change the background and make a character speak, when clicked Like scratching, the website lets users mix together different media (including graphics, sound, and other programs) in creative ways by creating and 'remixing' projects, like video games, animations, music, and simulations. Scratch takes its name from a technique used by disk jockeys called " scratching", where vinyl records are clipped together and manipulated on a turntable to produce different sound effects and music. As of 15 February 2023, community statistics on the language's official website show more than 123 million projects shared by over 103 million users, over 804 million total projects ever created (including unshared projects), and more than 95 million monthly website visits. Scratch is taught and used in after-school centers, schools, and colleges, as well as other public knowledge institutions. The service is developed by the MIT Media Lab, and has been translated into 70+ languages, and is used in most parts of the world. Scratch was conceived and designed through collaborative National Science Foundation grants awarded to Mitchell Resnick and Yasmin Kafai. Projects can be exported to standalone HTML5, Android apps, Bundle (macOS) and EXE files using external tools. Users on the site, called Scratchers, can create projects on the website using a block-like interface. Scratch is a high-level block-based visual programming language and website aimed primarily at children as an educational tool, with a target audience of ages 8 to 16.

The WeDo 2.0 kits are now available in the US and UK for Android and iOS smartphones and tablets, PCs and Macs. The STEM lessons are extra, but Lego Education will apparently offer a site-wide license. Like the consumer products, the educational kits are not cheap, running around $2,000 per classroom. For instance, kids get lessons about recycling by designing a truck, and even learn about biology and pollination, though we're not sure how they pull that off with Lego bricks. According to Techcrunch, Lego has has developed a curriculum with over 40 hours of science lessons normally taught in fourth grade. On top of robotics, the next-gen WeDo Kit also teaches kids STEM basics via various science projects. The whole thing is driven by a tablet-based drag-and-drop interface that helps kids code basic robotics apps. The new kit also replaces the old USB cables with a Bluetooth LE hub that connects to the motors and tilt sensors. As before, it's designed to teach kids the basics of robotics, thanks to the Mindstorm-like sets. Lego Education has revealed the WeDo 2.0 robotics kit aimed at elementary school students, over eight years after launching the original WeDo. You may not have been able to play with Lego in school, but your kids can. ![]()
