The head teacher system in colleges and universities has been established since 1949 in China,but there are still many deficiencies in the implementation.One of the important problems is how to do the work of coordinators in colleges and universities.At present,most of the head teachers in colleges and universities in China are not full-time coordinators.So,they don't have sufficient working experience about managing undergraduate students.According our experience,we will discuss how to do work about managing undergraduate students as a coordinator.Head teachers should lead the ideological development of undergraduate because action is controlled by thoughts.If all students have a correct ideology,it's easy to achieve the educational goals.Therefore,we believe that college head teachers should take thought as the starting point,fully take the subjective initiative of college students through moistening things silently and"Inaction",achieve the educational purpose of"doing everything",and cultivate new people of the times with all-round development of morality,intelligence,physique,beauty and labor.
