Abstract: In order to overcome the shortcoming that the existing quality guarantee system of
curriculum teaching lacks in the universal adaptability, this paper focuses on the current curriculum
teaching situation and probes into the curriculum quality guarantee strategy based on the effective
teaching theory. Based on the literature review and data analysis of the influencing factors of the
curriculum teaching quality, seven major influencing factors of curriculum teaching quality were
sorted out centering on teachers and students. Then a quality guarantee model of two-stage
hierarchical curriculum teaching was established based on the effective teaching theory. The model
has the advantage of self-evaluation and continuous improvement. Furthermore, a self-assessment
form of teaching quality for teachers was designed to realize the internal evaluation and continuous
improvement of curriculum teaching quality. Moreover, a calculation formula of correlation degree
between evaluation indexes and influencing factors was established. In addition, based on the reform practice of curriculum teaching, four quality guarantee strategies of curriculum teaching, which
include elaborate course teaching design, flexible teaching mode, construction of the community of
interests between teachers and students, and give full play to the role of model teachers, were
proposed from the perspective of teachers. Finally, this paper analyzed the implementation effect of
the above proposed curriculum teaching quality improvement strategies in the teaching practice of the
postgraduate courses-computer graphics and digital rapid prototyping. Then the curriculum teaching
effects of the classes of 2017 and 2018 was studied and compared. According to the results, the final
grades excellence rate of students in the class of 2017 and 2018 is 5% and 28% respectively, which
shows that the curriculum teaching effects of the class 2018 after the reformation have been greatly
improved. Therefore, the proposed method in this paper will provide implications for the
implementation of the quality guarantee strategy of curriculum teaching in colleges and universities.
