Newman believes that apart from learning knowledge, it is more important for students to communicate with each other, learn from each other and become friends with each other. He also believes that the ultimate goal of education is to cultivate people who have the ability to serve the society, not to teach some specific skills. Newman opposes teaching students the specific skills of a certain major from the beginning, and thinks that college students must have a wide range of knowledge and should not be limited to a specific major prematurely. Of course, to realize the comprehensive education, it is not enough to have conceptual recognition, but also to have two elements at the same time: one is to give students the freedom to choose courses and change majors, and the other is to have the strength to offer enough and extensive courses.

Case Harvard University, first of all, gives students absolute freedom to choose courses. Freshmen can choose courses at will regardless of their major, and gradually understand their real interests in the process of learning; Secondly, Harvard offers enough courses. Harvard has about 6000 undergraduates. They have actually offered 6,000 courses, and they can also go to the Massachusetts Institute of Technology next door.

2. Humboldt vocational education

Humboldt's higher education system attaches great importance to vocational education and skills education, emphasizing that college students should learn knowledge that can be used immediately at school, and they can provide services and create value for the society as soon as they leave the campus. In order to enable students to do this, many majors in Humboldt University graduate in five years, and the last two years are very advanced professional knowledge. Moreover, universities adopting Humboldt system will spend a lot of money to establish graduate schools, which is also the material basis for realizing professional education.

Massachusetts Institute of Technology, a famous case, is a model of implementing Humboldt-style professional education. Its most prominent feature is that freshmen have the opportunity to participate in real scientific research. Generally speaking, the scientific research that undergraduates take part in in universities is actually that professors let students practice their hands and do something casually, because many professors think that undergraduates can't do scientific research projects themselves and have no time to help students, but MIT is different. Professors at MIT will let undergraduates participate in their own funded research projects and let them take a job in this project, which requires professors to spend time guiding students and take corresponding risks.
