The process of building a culture of evidence involves using data to understand where students are experiencing problems, designing strategies for remedying those problems, implementing them, and then evaluating the effectiveness of those implemented strategies. This case study is about two programs that were implemented within the last two years at El Centro College of the Dallas County Community College District--in-class instructor-guided service learning and supplemental instruction--and the challenges in institutional research in building a culture of evidence. Both programs showed significant improvement in their respective measurements for general and developmental psychology classes. However, without an easy-to-use data collection, central repository, and analysis system, conducting the kind of institutional research that could inform improvements to program and institutional performance can be quite difficult. Across the institution, data entered at different times by multiple departments and the difficulties in extracting data from multiple systems were the major impediments to collecting standardized data.
