Based on learning theory, teaching theory and communication theory, this paper uses systematic methods to analyze teaching problems, determine teaching objectives, establish strategic plans to solve teaching problems, try solutions, evaluate the results of attempts and modify plans. Specifically,

You can know and understand from the following aspects:

(1) The purpose and research object of instructional design.

The ultimate goal of teaching design is to improve teaching efficiency and teaching quality, so that students can learn more knowledge in unit time and greatly improve their abilities in all aspects, so that students can get good development.

Teaching design, also known as teaching system design, takes curriculum plan, curriculum standard, unit teaching plan, classroom teaching process and teaching media materials as different levels of the teaching system and takes the teaching system as the research object. Therefore, the whole learning and teaching activities of students and teachers can be taken as the research object.

⑵ Instructional design emphasizes the application of systematic methods.

The systematic method of instructional design is:

Teaching design should start with "why to learn" to determine students' learning needs and teaching purposes;

According to the teaching purpose, further determine what specific teaching content and teaching objectives are used to achieve the teaching purpose, so as to meet the learning needs of students, that is, determine "what to learn";

What strategies should be adopted to achieve specific teaching objectives, so that students can master the required teaching content, that is, "how to learn";

It is necessary to comprehensively evaluate the teaching effect and modify the above links according to the evaluation results to ensure the promotion of students' learning and the success of teaching.
