A college-level applied sociology course in which students use sociological theory or research methodology to solve social problems is described. Guidelines for determining appropriate projects are: (1) the student must feel there is a substantial need for the project; (2) the project must be approachable through recognized sociological techniques, and (3) the project must be feasible within the time frame of the course. Some projects students have conducted are described, e.g., they have built new social organizations and started a babysitting service as a shelter for potential child-abuse victims. In organizing and structuring the course, principles from classic sociological theories are used, and this strategy is shared with students. For example, sensitized to anomie by Emile Durkheim, the author took care when structuring this course to clearly draw norms. Students are expected to contribute much of the direction for their project. However, structure is provided through weekly group meetings, a private consulting session, and a student journal containing weekly progress reports. Research techniques used in the projects include experiments, survey research, field work, and documents analysis. One of the biggest challenges is helping the students deal with values. (RM)
