1 the form of multimedia teaching courseware
Courseware will always serve teaching. Courseware appears to show what ordinary teaching tools and methods can't. In practical application, courseware has the following common forms:
1, Showcase courseware: Showcase courseware, like slides, has a simple structure and is the most widely used courseware type.
2. Tool-based courseware: Tool-based courseware provides students with one or several operating tools, such as sketchpad and text editing, so that they have the material conditions for hands-on practice.
3. Learning courseware: Students can learn what they need to master without a teacher by learning courseware.
4. Resource-based courseware: In classroom teaching, the problems mentioned by students often involve many aspects. Courseware can be made into resource form, and students can consult it when they need it.
5. Network courseware: Network courseware is aimed at single machine. There is no difference between the two in essence, but the platforms used are different. The popularity of broadband, campus network and the prosperity of distance education have promoted the rapid development of network courseware.
2 multimedia teaching courseware script writing
The scripts of multimedia teaching courseware are divided into text scripts and production scripts. Scripts, like scripts, need to describe in detail the steps of courseware making, the materials contained and the methods used.
1, text script: text script is a form of description according to the requirements of courseware teaching design; It is used to explain the teaching object, the teaching function and characteristics of the courseware, the scope of application and the way of use of the courseware. And describe the knowledge structure of the courseware and the knowledge units and knowledge points that make up the knowledge structure in detail, and compile the teaching plan according to the teaching content and teaching objectives.
2. Making scripts: Making scripts is a form of description according to the requirements of courseware system design. It is also a process structure design, which is divided into sequence structure and branch structure. As the name implies, sequence structure makes the courseware execute in order, and the score structure is the root.
Courseware is divided into corresponding modules according to the content, and you can jump to any module when operating courseware. Obviously, the branch structure is more humanized than sequence structure, and it can return quickly even if it is wrongly operated; The sequential method is easy to operate, so that users who are not familiar with computer operation can easily get started. In fact, most courseware is made by combining these two structures. There are few courseware made with only one structure. Inside each module is a sequence structure.
3 the use of materials in Flash courseware
1. Use of background music
In Flash, to play music, you must first import a sound file into the Library panel, and then drag it to the stage. Select the Import command under the File menu. In the import dialog box that pops up, select a sound file. The sound files that Flash can import are mainly WAV and MP3 formats. Click the open button to import them into the library, and then select the library command under the window menu to pop up the library panel. You can see that some of them have just been imported. Select the background music layer and drag the desired sound component from the Library panel to the Stage. If you want to set an effect, you can set various sound playing effects in the effect drop-down list box of the property panel, such as left channel, right channel, fade out from left to right, fade out from right to left, fade in and fade out, and so on. You can also set the sound playback effect yourself, and then click.
2, the use of video
Flash MX can support importing QuickTime movies (mov), Windows videos (avi), mpeg movies (mpg, MPEG), Windows Media(asf, wmv), digital videos (dv, dvi) and Macromedia Flash videos (flv). The import method is as follows: Select the import command under the File menu, select the movie file in the pop-up import dialog box, click the Open button to pop up the import video settings dialog box, keep the default settings of the dialog box unchanged, click the OK button, and then click the Yes button after the message box pops up, and the system will automatically extend the number of frames to display all movies.
3, the use of animation
There are three main types of animation in Flash: tween animation, frame-by-frame animation and script animation.
3. 1 tween animation means that only the start key frame and the end key frame are drawn, and the intermediate transition frame is automatically supplemented by Flash. Tween animation can be divided into motion tween animation and shape tween animation. If the tween animation is successful, an arrow from left to right will appear between two animation frames on the timeline. If it doesn't succeed, it is a dotted line. In tween animation, there is only one instance (or group, text, etc. ) can be placed on the first floor, otherwise the animation will fail.
3.2 Frame-by-frame animation belongs to the traditional animation production method, which is suitable for making animations with large shape changes. Every frame of frame-by-frame animation is a key frame, that is, every frame needs to be drawn by the designer.
3.3 Script animation is an animation generated by ActionScript, a scripting language built into Flash. For beginners who want to write action scripts, they can rely on Flash's unique "Action" panel to achieve it. For example, the action script used to define three buttons in the action panel is as follows:
Play the action script of the button.
Play the action script of the button.
Open (release) {
play()；
}
The action script of the stop button.
Open (release) {
stop()；
}
Action script for the "Exit" button
Open (release) {
fs command(" quit ")；
}
To realize interaction through movie clips, such as dragging objects, copying objects, changing the properties of objects (position, size, color, transparency), etc., you can open the action panel, switch to expert mode, and directly enter the following code in the script pane.
Onlipevent(load){// movie clip loading event
This.onPress=function(){ // mouse down event
this . start drag()； //Start dragging movie clips
};
This.onRelease=function(){ // Release the mouse event.
this . stop drag()； //Stop dragging movie clips
};
}
Comprehensive application of 4 Flash courseware
Flash courseware can not only be published as an animated SWF and execute EXE independently, but also be used in other multimedia production software, which greatly expands the application scope of Flash courseware.

5 concluding remarks
Courseware is the product of the combination of computer technology and classroom teaching. Making a good courseware depends not only on excellent software system and superb skills, but also on the mastery of the course, rich imagination and creativity of CAI courseware makers. With the need of network teaching and distance teaching, making multimedia courseware with Flash has become the mainstream of CAI courseware making.
