Jaspers thought that there are three kinds of educational methods such as academic approach education,master and apprentice' approach education and socrates' approach education.it is perceived from jaspers' deep comprehension and classification to educational methods that jaspers emphasized socialized educational method and paid great attention to selfhood education and he enthroned conversation.according to the character of jaspers' educational methodology,we should restore original appearance of education in educational practice.we should alter single irrigational method in conventional education and adopt and select reciprocal educational method,with which teachers and students can interact each other.at the same time,the students can interact each other too.so the students can be educated in the atmosphere of equality and harmony and interaction.

雅斯贝尔斯认为，现存的教育方式有经院式教育、师徒式教育和苏格拉底式教育等三种。从雅斯贝尔斯对教育方式的深刻理解与分类，我们看到，雅氏在教育方法上强调交往的教育方法，注重自我教育及推崇对话。根据雅斯贝尔斯教育方法论的特点，在实际的教育实践中要还教育的本来面目，改变以往传统教育中单一的灌输模式，采用与选择师生互动的交互式的教育模式，从而创设师生互动，生生互动的情境，在平等、和谐与互动中达到对学生教育的目的。
