It is increasingly significant to implement the “Fourteenth Five Year Plan” development strategy, achieve the goal of cultivating talents in product design, practice the fundamental task of establishing morality and cultivating talents in higher education, promote the organic integration of knowledge, ability and quality, help the construction of national first-class undergraduate majors, and explore the practical path of teaching innovation in product design courses. There, however, are some problems with the teaching practices of specialized courses, such as slow updating of teaching content and mismatch between teaching and demand. Other problems include students' low learning efficiency in class, lack of learning arrangement after class, teaching-learning asynchronization, and backward, single and inefficient teaching methods. Teachers' great pressure in teaching and students' low enthusiasm for learning are also found. Therefore, it is urgent to take effective measures to update teaching content, implement the second classroom, innovate teaching modes, expand teaching ideas, practice “five +” teaching, adhere to the path of “integration of five modernizations”, so as to improve the construction of professional courses, and provide ideas and methods for the construction of professional courses of design disciplines in the new era.
