Practice and Exploration of “Tries-Tries” Flipped Classroom Teaching Mode in Mechanical Courses

As a new teaching mode, the flipped classroom has become a research and application hotspot in university education. How to realize the conversion between students and teachers in flipped classroom and how to organize the implementation process of learning before class, in class and after class are the key and difficult points of research. Based on the knowledge internalization and construction as the core, combined with the flipped classroom teaching mode, this paper constructed a set of “Tries-Tries” flipped classroom teaching mode. Through the implementation of three-ones and three-steps teaching, the process of knowledge internalization completes four times, and each group has learning outcomes, and it makes the participation of students reach 100%. It will provide a reference for the research and application of science and engineering flipped classrooms.
