Abstract:Introduction is the first lesson of all the courses in universities. A good lesson of Introduction can initiate students' sense of mission, enterprise, and responsibility for science. Through years of teaching research and practice, we believe that the principal purpose of Introduction is to stimulate students' curiosity and thirst for knowledge, ignite their enterprise and sense of urgency, and make them be keen on and know how to learn this course. In order to achieve the above teaching objectives, we constructed a teaching mode for the lesson of Introduction by collaborating teaching contents, methods, and objectives. First, teachers use interesting and flexible means to introduce scenes and objects and then ask questions. After that, teachers, through systematic guidance and inspiration of independent thinking, encourage students to explore the basic attributes, history, current status, and prospects of the subject, as well as the purpose, task, and method of learning, so as to inspire students' ambition and responsibility and enhance their determination and confidence of learning the course well. We takes the Introduction of General Phytopathology as an example to illustrate the teaching process with the above mentioned teaching mode. Years of teaching practice have proved that the above teaching mode can introduce standard, systematic, and comprehensive contents in the first lesson Introduction, which is in line with the teaching objectives. Moreover, this teaching mode is characterized by rich connotation, strong operability, and good teaching quality, which is thus suitable for popularization.
