Research on Teaching Reform of Computer Application Foundation Course Based on PBL and "Training of Job Demand Mode"

PBL is a complete approach to designing learning situations; "Training of job demand mode" is the specific implementation of the training requirements for applied talents. This paper aims to cultivate the application of "professional position talents" and explore the objectives, contents, methods and means of carrying out classroom teaching in the modern educational technology environment. Status and Background Analysis "Computer Application Foundation" is a public foundation course for all majors; it is an introductory course for students to learn computer system knowledge; it is also a basic skill that students must master from school to social work. At present, there are several disadvantages in the form of education and teaching in this course. (1) Teaching content is not in sync with market demand. Most colleges and universities have been teaching the "Computer Application Foundation" course at the stage of "theory knowledge can be understood and the machine exercises can be completed". As everyone knows, the "Computer Application Foundation" course needs to be applied to specific professional positions. The general case used as a practice in the teacher's classroom may not be able to meet the needs of real jobs, so that students need to continue or re-learn to adapt after entering the job. (2) The teaching goal reflects the test objectives, not the ability goals, so that students can only solve the problems that the teacher has said, and will not give rise to the opposite, and will not self-exploration to solve new problems. In the face of the case that the teacher has said, it can be solved according to the ideas given by the teacher; in the face of new work content and challenges, it shows a state of being overwhelmed and unable to start. This shows that we are only "giving people a fish" and there is no "giving people to fish". (3) Teaching methods and cognitive rules are not suitable, leading students to enter the classroom ignorantly, go out of the classroom in confusion, do not know what they are doing now, and do not know what they can do when they are on the job. "Computer Application Foundation" has always adopted the method of using knowledge points as a teaching unit. Students need to learn more than a dozen hours, and after learning the whole software, they will know what the software can do. Therefore, in the process of learning, students have no goals, and after learning for a long time and cannot see the results of learning, it is easy to lose interest in learning. Therefore, the use of scientific teaching methods, the integration of computer classroom teaching content and the professional characteristics of students, has a very practical significance.
