The biggest difference between internal trainers and social lecturers is that students have to be promoted after training. Social lecturer professors don't have to consider long-term effects. The most important thing to improve the training effect is to grasp the needs, grasp the needs of students, and compile targeted training courses in combination with the actual needs of enterprises and projects. It is necessary to clarify the training objects and cultivate them in categories. Due to the uneven level of trainers, it is difficult for a well-designed course to meet different levels of managers. In the form of training, it should be flexible, vivid and lively, easily accepted by employees, and avoid formalism and going through the motions; It is necessary to closely link with practice, form a benign interaction between the two sides, and avoid one-way indoctrination.
