Abstract: Aiming at the deficiencies of the traditional experimental teaching model which appointed truth value, such as fuzzy experimental criteria, solidified experimental content, and crude data processing, this paper carried out the reform and exploration work of new engineering basic mechanics experiment teaching mode. By adjusting the teaching concept, enriching the experimental content and system data processing, the criteria for basic mechanics experiments are clarified, and a new teaching mode of basic mechanics experiment is constructed, which is centered on students' independent practice and aims at cultivating practical innovation ability, humanistic quality and national feelings.
