Visual Programming Exam Preparation Guide
Course Introduction
Visual Programming introduces students to programming concepts through graphical user interfaces, enabling them to design and build software by manipulating visual elements rather than writing traditional code. The course covers the fundamentals of event-driven development, logic flow, data handling, and graphical user interface (GUI) design, utilizing tools such as Scratch, Blockly, or visual programming environments for professional development like Visual Studio's drag-and-drop components. Students learn to solve problems, create interactive programs, and understand core computational thinking principles, making programming accessible and fostering creativity through hands-on projects and collaborative exercises.
