Getting Started with Scratch Programming

What is Scratch?

Scratch is a free graphical programming language designed by the Massachusetts Institute of Technology (MIT) for children and beginners. By dragging and dropping colorful building blocks, users can create interactive stories, animations, games and music. Scratch is designed to be simple and intuitive, making it easy to get started and promoting creative thinking and problem-solving skills.

Key Features of Scratch

• Graphical interface:No need to write complicated codes, programming can be done by assembling building blocks like a puzzle.
• Block-based programming:Each building block represents an instruction (e.g. move, play sound, show dialogue, etc.), making learning programming logic easy and intuitive.
• Community sharing:Scratch has a global community where users can share their projects and learn and communicate with each other.

Why choose to learn Scratch?

Learning Scratch is a great starting point into the world of programming. It provides basic programming concepts such as variables, conditional statements, loops, etc. for both children and adults. In addition, Scratch emphasizes creativity and collaborative learning, and users can create various multimedia projects and share their works with others.

Benefits of learning Scratch

• Easy to get started:Even if you have no programming experience, you can get started quickly through simple operations.
• Develop logical thinking:By designing games and stories, you'll learn how to break down problems and solve them using a programming language.
• Get creative:Scratch allows you to apply programming to creative projects, improving your hands-on skills and creative thinking.
• No software download required:Simply open your browser and go to the official Scratch website to start creating projects.

How do I start learning Scratch?

1. Register and enter the Scratch platformFirst, open Scratch official website And register an account. Registering an account allows you to save your projects and share them with others. After completing the registration, you can directly click the "Create" button to enter the programming interface.
2. Understanding the Scratch programming interface
   • Stage:This is where your items will be displayed and all characters will follow instructions.
   • Sprite:The main characters in the project can be people, animals, objects, etc., and set their behaviors.
   • Blocks Area:You can drag blocks from the left into the block area and combine them to form programs.
   • Brick Type:
     • Action Blocks:Control character movement, rotation, etc.
     • Appearance building blocks:Change the appearance of the character, such as displaying text or changing the costume.
     • Sound Blocks:Play sound or music.
     • Event building blocks:Set trigger conditions, such as executing a program when clicking a green flag.
     • Control blocks:Use loops and conditional statements to control program flow.
3. Creating your first projectAfter getting familiar with the interface, create a simple interactive screen:
   • Step 1:Select a role. The default character is the Scratch cat, and you can add other characters by clicking "Select Character".
   • Step 2:Add actions. Drag the "Move 10 Steps" block to the block area and click the block to make the character move forward.
   • Step 3:Add interactivity. Use the When Green Flag is Clicked block to make the program start running when the green flag is clicked.
   • Step 4:Add sound effects. Add the Play Sound Effect block to the program to add sounds to the character's actions.
4. Storage and sharingAfter completing your project, don’t forget to save and share it with the Scratch community to learn from other users.

Improve your Scratch skills

• Using variables:Learn to create and use variables to record data, such as scores and times.
• Conditional statements and loops:Explore control flow concepts in depth and make your programs more interactive.
• Cloning and duplicating characters:Use the clone function to have a character copy itself, suitable for enemies or items in game design.
• Homemade building blocks:When creating complex programs, you can make your own building blocks to simplify the program structure.

in conclusion

Scratch is a powerful and fun tool that makes it easy for beginners to enter the world of programming.
