The evaluation and modification of multimedia courseware is an important content in the development process of multimedia courses. This content actually exists in the environmental analysis, teaching design, script design, software writing and other stages of multimedia expansion development.

The development of high-quality multimedia courseware is a complex system project that usually requires the full cooperation of all members of the development team. Therefore, it is necessary to give a specific description of each stage and task of the development process and use it as a guide for action. Overall Generally speaking, the basic stages of multimedia courseware development are the same, including environment analysis, teaching design, script design, software writing, evaluation and modification, and use and distribution. First, let’s look at environmental analysis. Environmental analysis of multimedia courseware mainly includes analysis of teaching objectives of multimedia courseware, analysis of multimedia courseware usage objects, and cost estimation of developing multimedia courseware. Analysis of the teaching objectives of multimedia courseware is to clarify the specific requirements of teaching, such as mastering new concepts, consolidating knowledge that has been learned, training the ability to solve certain problems, the required degree of mastery and inspection methods, etc. Multimedia courseware uses object analysis to analyze the adaptability of students' original knowledge level or original psychological development level to new learning when they perform new learning or exercises.

The fifth is evaluation and modification

The task of this stage is to implement the teaching strategies determined in the instructional design stage and the production scripts obtained in the script design stage using some kind of multimedia creation tools, such as powerpoint, authorware, etc. or high-level computer languages ​​such as C language, etc., for To improve efficiency, we should try our best to collect and utilize existing multimedia materials, and edit and process them according to the needs of multimedia courseware content. After the multimedia materials are collected and edited, they can be integrated with multimedia creation tools. After the multimedia courseware program is written, it should be Carry out careful debugging. The purpose of debugging is to find out various possible errors hidden in it and eliminate them.

A script is a detailed report on the design of the computer-student interaction process based on teaching design. It is a direct blueprint for the next stage of software writing and an important basis for the design and implementation of multimedia courseware. Therefore, script design is also a multimedia course development process. It is the transitional stage from teaching strategy-oriented design to computer software-oriented implementation. The scripts of multimedia courseware can be divided into two types: text scripts and production scripts. Text scripts are text descriptions of "what to teach", "how to teach" and "what to learn" and "how to learn" in multimedia courseware? Including teaching goal analysis, teaching content and knowledge point determination, learner characteristics analysis, learning mode selection, media selection, etc. As shown in the picture is the text script of the primary school Chinese courseware "Beijing". Script production is based on the text script, based on educational science theory and teaching design ideas, to design multimedia extended interactive interfaces and media expression methods, and further adapt the text script into a form suitable for computer implementation. As shown in the picture is the production script of "Learning New Words" In the design of multimedia courseware, the reasonableness of the computer screen layout reflects the quality of the courseware to a certain extent. In the script design process, the functional areas of the multimedia courseware interface must be carefully designed and divided according to the specific conditions of the multimedia courseware. Try to make it possible for various types of information to be presented in relatively fixed positions in the same multimedia courseware to avoid students being distracted by having to look for information on the screen every time. As shown in the figure, a Typical screen layout suitable for individual guidance and operation and practice multimedia courseware. Of course, it can also be adjusted accordingly according to changes in information capacity.

The second is teaching design

First, the general characteristics of students
