CONTENT OF THE LESSON:

What Is Visual-Based Programming?

Visual-based programming is a fun way to create programs using blocks or pictures instead of writing long and tricky code.

It’s like building with LEGO — you snap blocks together to make a game, animation, or app!

You don’t have to worry about spelling or typing — just drag and drop the blocks to make your computer do something!

Examples of Visual-Based Programming Tools:

1. Scratch – It lets you make games, stories, and animations with colorful blocks.
2. Minecraft Education Edition – It uses blocks to teach coding logic in a fun world.
3. Alice – It helps you make 3D animations using drag-and-drop blocks.
4. MIT App Inventor – It lets you build simple apps for phones using coding blocks.

Uses and Benefits of Visual-Based Programming Tools:

1. It is good for beginners – Kids can learn to code without typing.
2. It encourages creativity – You can make your own stories, games, and projects.
3. It is used in schools – Teachers use it to teach computer skills and logic in a fun way!
