An experiential science program, such as a summer course at a field station, requires unique assessment tools. Traditional assessment via a pencil-and-paper exam cannot capture the essential skills and concepts learned at a summer field station. Therefore, the authors developed a pre- and postcourse image-based analysis to evaluate student perspectives, created weekly pass/fail quizzes, and produced a comprehensive laboratory and field practical examination for our assessment of student learning.
