A great number of experiments on education system,curriculum,teaching methods,administeration,selection and organization of knowledge were performed in higher education in China in the second half of the 20th century. As a whole ,we find that they changed from serving the political,economical and social needs to focusing on variables of experiments themselves. Selection and organization of knowledge became the theme of experiments. Effective means and methods of education constituted the key contents. However, while concerning scientificity and impartiality of the experiments were tested, their motive,process and results still need to be carefully examined.
