First, lecture is a kind of teaching research and teacher training activity in which teachers verbally express the teaching ideas and theoretical basis of specific topics, that is, on the basis of preparing lessons, teachers tell their own teaching designs in front of peers or teaching and research personnel, and then the listeners comment on them, so as to communicate with each other and improve each other.

Second, structured interview is a question that examiners put forward to us in view of some common phenomena in school teaching. It includes teachers, teachers and students, students, schools and families, and it is a test of whether we are suitable to be teachers.

Third, there is no unified definition of defense. We often rely on some professional theoretical knowledge we have learned, the characteristics of students' physical and mental development, and some specific requirements put forward under the huge social background. Generally speaking, it is three points: the relaxation of one's own mentality when defending, the adaptability and psychological quality when facing the examiner, and the grasp of the knowledge points in defending.
