The whole courseware is easy to embed in the webpage and is suitable for wireless network transmission on the Internet. Use the scanner to scan the text part into the computer, recognize it with Hanwang HWOCR5.0 recognition software, and edit it in Word. Use the video processor and audio processor of Kingsoft Hasee II to convert the VCD to the .avi video file format, use Windowsmoviemaker to edit and integrate the edited film, and finally import the required materials into Flash as needed to make the courseware . In order to ensure the correctness and effectiveness of the basic actions in the courseware, the empirical validity evaluation method is adopted, and the validity of the courseware content is tested.
