Effect of service-learning on knowledge about older people and faculty teaching evaluations in a physical therapy class.

The major purpose of this study was to identify the knowledge, misconceptions, and bias regarding aging among graduate physical therapy students and to determine whether service-learning modified any of these variables. A cohort of 40 students in a graduate physical therapy program was randomly divided into an experimental (service-learning) or control (no service-learning) group. General knowledge and attitudes about aging were measured by Palmore's Facts on Aging Quiz I. The Wilson Student Evaluation of Faculty tool measured student evaluations of a faculty member at the end of the semester. Two-way analyses of variance with repeated measures revealed that all students increased their knowledge about aging, p < .05. However, students who initially had negative attitudes toward older adults significantly improved their attitudes only after the service-learning experience, p < .05. A t-test revealed that teaching evaluation scores were significantly lower in the service-learning course, p < .05. The results suggest that service-learning effectively enhanced both the knowledge and attitudes of physical therapy students toward the older adult. Although service-learning imparted better learning for the student, there was some risk to the faculty member as evidenced by lower teaching evaluations.
