1. Education is a wide range of human activities, including various forms and ways of learning and growth. Education doesn't just happen in schools, it permeates all aspects of human life. Education can be divided into different types, such as formal education, informal education and informal education.

2. Formal education refers to formal educational institutions, such as primary schools, middle schools and universities. It usually includes subject courses and examinations, as well as standardized assessment and certification. Formal education is generally regarded as a planned, organized and purposeful form of education, which can provide students with systematic knowledge and skills.

3. Informal education is carried out in daily life, such as reading, observing and participating in activities. It is usually not planned and organized by teachers or educational institutions, but is selected and controlled by learners themselves. Informal education is usually closely related to real life, and learners can apply and experience the knowledge and skills they have learned in real situations.

4. Informal education is a self-directed learning form, which is usually realized through self-education, continuing education and training. Informal education usually has more flexible learning methods and wider learning contents, which can meet the needs and interests of different learners.

The basic principles of education are as follows:

1, principles of education. The principle of education means that education must meet the purpose of education, that is, education must have educational significance. The purpose of education is to cultivate people with all-round development in morality, intelligence, physique, beauty and labor, so education must pay attention to cultivating students' ideological and moral quality, cultural quality, physical quality and aesthetic quality.

2. The principle of creativity. The principle of creativity means that education should focus on cultivating students' creativity and innovation ability. The cultivation of creativity requires teachers to change the traditional teaching methods and pay attention to heuristic teaching, inquiry teaching and situational teaching, thus stimulating students' interest in learning and creative desire.

3. Subjectivity principle. The principle of subjectivity means that education must respect students' subjective status and give full play to their subjective role. Students are the main body of learning, so they should actively participate in the learning process, give full play to their subjective initiative and master learning methods and skills.

4. The principle of unification. The principle of unity means that education must pay attention to students' all-round development and organically combine students' knowledge, skills and emotions. Education should focus on cultivating students' comprehensive qualities, including knowledge, skills, emotions and values, so as to promote their all-round development.
