All schools have three kinds of courses:
1. Explicit curriculum: refers to various disciplines and purposeful and organized extracurricular activities formally included in the school teaching plan in order to achieve certain educational goals.
2. Potential curriculum: refers to the educational practice and results of courses that are not clearly stipulated in the curriculum plan and school plan, but are regular and effective components of school education, and can be regarded as hidden, unplanned, unclear or unrecognized.
3. Empty curriculum: This is 1979, proposed by Eliot W. Eisner, an American aesthetic educator and curriculum expert. It includes two dimensions: one is the intellectual process that schools should pay attention to but ignore, and the other is the content and subjects that schools should have but don't have. That is, in the process of curriculum reform, the school and society intentionally or unintentionally excluded from the school curriculum system.
The main contents of the course:
1. The influence of students' interpersonal communication in school, such as thinking mode, values and behavior mode.
2. The influence of institutional and non-institutional culture formed by schools and classes for a long time, such as the traditions, ethos, public opinion, ceremonies, rules and regulations of schools and classes.
3. Physical and cultural influences of the school's physical environment, such as school buildings, campus environment and classroom layout.
