In the context of constructing new engineering courses, this paper puts forward a concept of “project-based workshop teaching” to address problems of disconnection between theory and practice, rigid teaching content, inaccurate assessment in the teachings of traditional mechanical courses. This idea involves course resource construction, teaching method transformation, and divergent evaluation exploration. Other methods include “our modernizations” resource support course construction, “three entries” classroom driven teaching reform, and “one process, three divergences” evaluation, which are designed to gradually create a mechanical course with attractive resources, durable content, and outstanding students. All those approaches improve traditional teaching and evaluation model, and achieve good teaching results in many aspects, casting light on construction and reform of mechanical undergraduate courses under the new engineering background.
