Please tell us what types of materials are often needed to produce multimedia courseware, and explain how to obtain them.

The material types of multimedia courseware generally include text, pictures, sounds, videos, etc. The specific acquisition methods are as follows:

1. Text materials

In multimedia courseware Texts are a source of vast amounts of information for students. Text materials should be applied to multimedia courseware selectively, rather than copied in large sections. Text that highlights key points and demonstrates difficult points should be marked in large fonts and bright colors.

2. Picture materials

Picture materials are generally obtained through scanners, digital cameras and other hardware, and then processed through image processing software; they can also be obtained through software, such as screens Take a screenshot, or draw directly in graphics software.

3. Sound materials

We can collect sound materials or make our own. Making your own sound materials requires some necessary hardware and software. In terms of hardware, we often use microphones, recorders, audio cables, etc.

4. Video materials

Video materials can be obtained through external collection and internal production and collection. External acquisition uses a video capture card to record the video material on the video tape and camera to the computer hard drive through digital processing and compression, and then edits it through specialized video editing software.

Preparation of multimedia courseware

The preparation and collection of materials for multimedia courseware should be carried out according to the needs of the script. The materials can be obtained through a variety of ways, such as using a scanner to collect images, using Animation production software generates animations, uses a microphone to input voice, or obtains it from various multimedia material CDs.

The core link of multimedia courseware is production and synthesis. Its main task is to design the teaching process according to the requirements and intentions of the script, edit various multimedia materials, and produce them into highly interactive, flexible operations, and audio-visual effects. Good courseware. This is a highly technical job. Today's multimedia editing software is becoming more and more easy to operate and learn, making it easier for teachers to create lessons.

In actual production, a courseware is often divided into a series of modules, which are designed and produced separately, and finally assembled to generate an executable application. After final assembly, a comprehensive test must be conducted. The main purpose of the test is to detect whether the program can run smoothly, whether the internal connections are correct, whether various sounds and animations can be played normally, etc., to avoid errors during use.
