The experience of doing service alone does not guarantee learning. A deepened learning experience takes place when both academic and service work is complemented by a form of engagement that encourages critical thinking. In service-learning, thoughtful and organized reflection is necessary to enhance both the service and community work. Here are some helpful guides to assist in facilitating reflection with your students: The Four C's of Reflection and The 3 Levels of Reflection.
The American Association of Colleges and Universities (AACU) rubrics were developed by select campuses to share, develop and test rubrics that establish essential learning outcomes for undergraduate education (based on use of e-portfolios, journals, etc.). You can view a reflection rubric here and a civic engagement rubric here. Other rubrics can be found on the AACU website.
