Computer aided instruction also has a certain degree of blocking. The use of CAI makes students learn passively, without targeted education and guidance. The knowledge content is mainly presented by means of optical disks and other carriers. The process is somewhat mechanized, and the students are not completely active in learning. In addition, students lack the supervision of teachers, and may also have some inertia. If students have problems, they cannot get answers in time. In teaching, teachers can better understand all aspects of students and their habits, personalities and learning methods. The use of computer-assisted instruction may only be able to achieve the exquisite courseware. The form is single, and the teaching cannot be changed according to the students' emotional fluctuations. These problems will also be the place where we need to continue to develop in computer assisted instruction. Combined with the network environment, the computer aided instruction system developed to study the characteristics and process of students' learning thinking, seek the mode of learning knowledge, enable students to obtain individualized adaptive learning methods, truly teach according to people, so that students can learn faster and more effectively, and create a learning environment suitable for individual characteristics for students. At the same time, solve the problem that the existing education software is not highly targeted, improve the "intelligent" level of the computer aided instruction system, and combine the learning menu according to the students' knowledge base, ability base and learning history, provide appropriate learning methods and training strategies to help students learn. © 2023 CAD Solutions, LLC.
