Learn Programming With Scratch From This Free Online Course By Harvard University

What is Scratch? Scratch is a free, open-source programming language developed by MIT (Massachusetts Institute of Technology). It is designed specifically for young learners, but its versatility and ease of use make it accessible to learners of all ages. Scratch is an ideal platform for introducing programming concepts to beginners, as it allows users to create interactive stories, games, and animations using blocks instead of text-based code. ### Key Features of Scratch

  • Visual Programming: Scratch uses a block-based interface, making it easy for learners to understand and manipulate code without prior programming experience. Drag-and-Drop Interface: Users can drag and drop blocks to create programs, allowing for a more intuitive and interactive learning experience. Community Support: Scratch has a large and active community of learners and developers who share their projects and provide feedback and support. * Cross-Platform Compatibility: Scratch can be accessed on desktop and laptop computers, as well as mobile devices, making it a versatile tool for learning.

    The course is designed to provide students with a comprehensive understanding of cybersecurity principles and practices.
