Lesson # content on this at the beginning to help the children speak scratch, I want to prepare.
Children, welcome to programming class for programming, many people will ask, "I grew up to become a CEO / scientist / star, what to learn programming? Programming programmers do not work?" As a graduate of Computer Science librarians, I can responsibly tell you, learning to program is not a profession, but a training, like learning a foreign language, practicing tennis, its biggest advantage is that the way the human mind can be trained to cultivate thinking integrity and logic, which has been on the way to look at the issue and deal with the problem of influence, to break the mindset, stimulate the imagination.
scratch by the Massachusetts Institute of Technology research and development of a graphical programming language software, its advantage lies in its variability, it can be fun and easy, so that 4-7-year-olds will be able to "play" can also be grand spectacular, using complex logic to complete a project. Scratch software to provide children with the tools as easy as possible: the building blocks of the program and a lot of character, stage, sound and other material, so that they give full play to their imagination to create. This can greatly improve learning motivation, exercise abstract thinking skills and creativity.
During programming easily understand the concept of logical operators, conditionals, loops, and other events, the exercise logical thinking, experience in running multi-directional thinking process is completed programming, the expansion of thinking, the direction of solving the problem. While training information, management, creation, choose different types including text, images, animation and various audio, video and other data files. Scratch encourage creative thinking, students constantly looking for new ways to deal with a variety of pre-set problems, and not just to teach them how to solve a given problem, thinking move, imagination and creativity will be flashed sparks.
Of course, the preparation of a program, but also on the patient (troubleshooter most exercise patience), and a test of teamwork. Well, now let's begin the first lesson to learn it.
First, download the program
First of all, let's put scratch download:
Download: https://scratch.mit.edu/
https://scratch.mit.edu/download/scratch2
There are desktop software and offline editors are two ways to choose, in order to facilitate our teaching, and now the first choice is now very stable version, Offline Editor 2.0, you should also pay attention to download Adobe Air also downloaded, which is 2.0 the system must be the foundation.
Auxiliary materials also has "Beginner's Guide" "Getting Started project" "Scratch Cards" three resources that can be downloaded to look, to understand the way this program is run, Basics are good.
Second, the installation and basic settings
When installing scratch2.0 offline editing, you need to install Adobe Air, double-click the installation file, click on the number of "next" to complete the installation, and then
Double-click the installation file after scratch2.0, "Next" until the installation is complete:
There are two main settings, language and font settings:
Setting the language: Click on the upper left corner of a small planet, select "Chinese."
Font: hold down the "shift", click on the upper left corner of a small planet, select "set font size" select the appropriate font size
Third, start your first scratch program
In the scratch editor we can see, this is a modular edit mode, just like our usual building blocks, the various parts of the module are connected together, we can achieve the desired effect, and now, we are well-known to the programming community the "! hello world" example, begin your first program it:
File -> New File, in this interface, we see a cat, we went to the role of the library in the "Select a role" button, select a role, you can also use the library background to change the background, click on the pencil icon same, also you can draw your own. Today we use the cat, it is our protagonist, I gave it a name, called "S", and it wants to say hello to you and tell you it was born in your computer, you want this world say "hello", how to do it?
We click event -> when the program starts, select Appearance -> said that the text was changed to "hello world!", Click on the little green flag, run the program:
Later, we will slowly explain other modules, and ultimately familiar with all modules.
after class homework:
1, on their computers, to install and set up the scratch, version 2.0 or 3.0 can be.
2, select a background, a character, so this role to introduce myself on stage.
