ABSTRACT
Over the past 10 years, the authors of this paper have implemented a series of project-based and inquiry-based learning initiatives in the calculus sequence at our institution. These initiatives took place in a department with an existing strong culture supporting teaching innovation and improvement. In this paper, we describe three initiatives in detail. We describe how in one, a syllabus redesign allowed for more instructor autonomy. In another, we were able to significantly improve student buy-in. We describe key support we received from our department and institutional leadership at each stage, as well as from working in community with each other. Finally, by looking at the long arc of change in our department, we hope to encourage others who are encountering roadblocks. By working in community, we have created an environment where active learning can flourish.
ACKNOWLEDGEMENTS
The authors would like to acknowledge all of the dedicated faculty in the department who dedicate countless hours to help their students learn. The authors would specifically like to acknowledge all of the leaders who have supported us. Specifically, the department leadership Will Traves, Vrej Zarikian, Jay Foraker, and Gary Lazzaro, our academic deans Bill Miller and Andy Phillips and our institutional leadership for teaching and learning Rae Jean Goodman and Karyn Sproles. Additionally, the authors want to acknowledge the instructors who assisted with our work by filling out time logs and making use of the curriculum including Jeff Parker, Pam Tellado, and other Calculus I instructors. Finally, the authors would like to acknowledge Christine von Renesse and Muraid Greene for coming to our institution to provide an outstanding inquiry-based learning workshop.
Notes
1 Over the past 10 years, there has been a push for more consistency. Individual instructors used to sometimes replace problems on the free response portion of the final; that is now frowned upon. Recently, some courses have held “grading parties” for the final exam, where each instructor grades one problem across many sections.
