title: The use of open-ended problem-based learning scenarios in an interdisciplinary biotechnology class: evaluation of a problem-based learning course across three years.
abstract: Use of open-ended Problem-Based Learning (PBL) in biology classrooms has been limited by the difficulty in designing problem scenarios such that the content learned in a course can be predicted and controlled, the lack of familiarity of this method of instruction by faculty, and the difficulty in assessment. Here we present the results of a study in which we developed a team-based interdisciplinary course that combined the fields of biology and civil engineering across three years. We used PBL scenarios as the only learning tool, wrote the problem scenarios, and developed the means to assess these courses and the results of that assessment. Our data indicates that PBL changed students' perception of their learning in content knowledge and promoted a change in students' learning styles. Although no statistically significant improvement in problem-solving skills and critical thinking skills was observed, students reported substantial changes in their problem-based learning strategies and critical thinking skills.
