In the research, the objective was to determine the effect of Project-based teaching method on the social skills of nursing students. While the research was planned as semi-experimental in a single group pretest-posttest pattern, its sample consisted of 70 fourth grade nursing students taking the course of Education in Nursing in the spring semester of 2011-2012 academic year. As the practical part of the course of Education in Nursing was carried out on the basis of Project-based teaching method, the students taking this course were determined to be included in the sample. Data were collected by using "Information Form" and "Social Skills Inventory". 11.5 version of SPSS program was used in the analysis of the data. Nursing students have moderate level social skills prior to and after the Project-based teaching practice. There is no statistically significant difference between the social skill average scores of students prior to and after the project-based teaching practice. Results show that Project-based teaching method did not affect social skills of students. In line with these results, it can be recommended that education activities available in the nursing programs be organized, improved and structured in a manner to promote the development of social skills in students.
