Aiming at the characteristics of modern design theory and method, taking virtual design technology as an example, this paper analyzes and discusses the teaching mode of modern design theory and method from three aspects: teaching, learning and examination, aiming at improving students' application ability and realizing the cultivation of innovation ability.

Paper Keywords: modern design teaching mode

introduce

With the rapid development of science and technology and the wide application of computer technology, the design field is undergoing a profound change, and various modern design theories and methods are constantly emerging, and the design methods are more scientific, systematic, perfect and advanced. The traditional design method has developed into a new comprehensive and interdisciplinary modern design theory and method. The wide application of modern design theories and methods will bring huge economic benefits to China's industrial production, and will play a great role in improving the design quality of China's industrial products, shortening the design cycle and promoting the modernization and scientificity of design work.

Modern Design Theory and Method involves a lot of contents, with a wide variety of design methods and limited class hours. The traditional teaching mode will inevitably lead to a dull classroom atmosphere and students feel bored and monotonous. Therefore, according to the characteristics of Modern Design Theory and Method, we should actively explore teaching methods, analyze students' knowledge structure, take application as the leading factor, adapt to the theory, and comprehensively use a variety of teaching methods in many aspects and angles.

Discussion on 1. Teaching mode

1. 1 Comparison between traditional design and modern design

The commonly used design methods in traditional design include theoretical design, empirical design and model test design. The design process is to use empirical formula, through a large number of manual or computer calculations, calculate and solve the size parameters and performance of the designed product, make a model prototype, and conduct experimental analysis and research on the physical prototype. Some tests are destructive. When defects are found through experiments, the prototype must be modified and remade, and the product can only be realized through repeated design and experimental design process.

There are many modern design methods: optimization design, virtual design, finite element analysis and concurrent design. The design process is to use modern design methods and computer application technology to truly simulate the characteristics and working environment of products in various virtual environments, quickly analyze various design schemes, and carry out experiments that are difficult or impossible for physical prototypes until the optimal design is obtained.

Through the comparative teaching of modern design and traditional design, students can realize the advantages and disadvantages of modern design, fully understand the design process and characteristics of modern design, so as to better understand modern design, use modern design methods to design and develop products, and increase students' enthusiasm for learning.

1.2 unification of theoretical teaching and applied teaching

Modern design theory and method design theory is complex, involving deep content and wide range, which is difficult for undergraduates to understand and accept. Therefore, in teaching, we should use the existing and mature design examples to introduce its application process and analysis method in product design, and at the same time give consideration to the main points of design theory, so that students can understand the theory and application of design method while using the characteristics of design process and design method, so as to understand the products with complex design, profound design theory and boring design method.

1.3 multimedia observation teaching

To improve teaching quality, we must also innovate teaching methods. Multimedia technology uses multimedia computers to comprehensively process and control various forms of media information, such as words, graphics, sounds, graphics, images, animations and moving videos. It is the best means of computer-aided teaching. It can establish a certain logical relationship among many media elements according to the teaching needs, so as to organically combine them and present them, and at the same time complete a series of human-computer interaction operations in this interactive process to complete the teaching objectives.

1.4 network teaching

Establish an online teaching platform, with the browser as the user interface, put course teaching documents, teaching research, academic trends and related information online to guide students' learning, establish a teaching forum, make full use of network functions, mobilize students' enthusiasm and initiative in learning, and make teachers and students learn together and make progress together.

2. Discussion on practical teaching mode

2. 1 Open the comprehensive design experiment week of modern design theory and method.

Because of students' limited classroom study, it is difficult to realize the comprehensive experimental training of modern design theory and application. By setting up a comprehensive experiment week, students can concentrate on a certain period of time, use the process of modern product design and development, comprehensively practice, understand and master the concepts, applications and skills of modern design theories and methods, so as to learn theory and practice and master modern design methods comprehensively.

2.2 Modern Design Methods and Theories Extracurricular Competition

In the way of proposition and independent proposition, students are required to use modern design methods to complete the design and development of a small product within a specified time, and analyze the related performance. By holding modern design extracurricular works competition, firstly, it can popularize the application of modern design, enhance students' ability to use modern design theories and methods, improve their learning enthusiasm, and better understand and learn professional knowledge.

3. Discussion on examination mode

The characteristic of modern design theory and method is to cultivate students' ability to use modern design, so the examination proposition should pay attention to the cultivation of application ability, and the examination can be conducted in various forms such as written examination and comprehensive training of product design and application.

3. 1 Teacher Proposition Computer Operation

In the classroom, teachers choose appropriate propositions according to the teaching emphasis, and ask students to complete the modern design and analytical experimental research of products with a modern design method on the computer within a specified time; At the same time, in order to master modern design theories and methods better and more, some modern design methods can be tested by written test, so as to master and understand modern design theories and methods more widely, that is, by combining practical operation with written test.

3.2 Design documents

This test method is to send the contents and requirements of the design to students, requiring them to complete the design within a period of time and submit design analysis papers. This test method is flexible, the topics can be large or small, and it can also be suitable for arranging design topics because of different people's abilities. At the same time, the design topic is really false in practical engineering, which gives full play to students' initiative, knowledge, practicality, interest and creativity. Designing products that meet the requirements in the virtual environment and writing them down in the form of argumentative papers can not only assess students' mastery of modern design theories and methods, but also exercise students' innovative ability.

4. Conclusion

Practice has proved that the teaching mode of combining teaching, learning and examination is effective, which can obviously improve the disadvantages of traditional teaching mode, increase the visibility, knowledge, practicality and interest of teaching, make the teaching process lively, full of rhythm and flavor of the times, stimulate students' interest in learning, creativity and participation, improve students' ability to analyze practical problems, and lay a solid foundation for students to apply their learned theories and skills to production and scientific research.
