The present research has been funded by the Russian Humanities Fund within the framework of the project No. 14-33-01001 ''Faculty Habitus' and Socialization of Students at a Classical University (Based on the Example of the Nizhny Novgorod State University N. A. Lobachevsky)'. The research is devoted to the role of field trips of biology students in the process of their socialization and personality growth. Despite a growing number of researches of youth in general and students in particular, both the theory and practice of the topic are understudied. The authors of the present article discuss the grounds and factors that define peculiarities of the socialization process during field trips based on the example of biology students. The main research methods used by the authors include theoretical analysis of Russian academic literature on social studies, pedagogy and psychology. The authors provide the basic theoretical grounds of the socialization process of biology students during field trips. The results of the research demonstrate that field trips play an important role in socialization of biology students and have an important influence on development of their social skills, social adaptation, development of interpersonal communication and creation of the 'Faculty Habitus' in general.
