We describe how one department moved from skepticism to wide-spread embrace of coordinated Calculus I. Data played a crucial role in this process. Details of this journey, including successful strategies and missteps, may provide insight and perspective to other departments starting on, or immersed in, similar transformational adventures.

In this paper, I highlight several facets of personnel issues that can arise during one's time as a mathematics department chair and recommend communication strategies to address them. The strategies involve situations with individual faculty members, general communication with faculty, and communication with the administration.

We present an outline for a year-long training session for potential departmental leaders. This outline is based on training led by the author over one academic year. The training consists of nine sessions with an emphasis on active learning among the participants.

In this article, the authors propose a department-level curricular committee structure, called Strand Committees, as a mechanism to facilitate oversight and enact significant change to policies and practices in specific courses. The primary goal of the Strand Committees is improving both student success and instruction while upholding a high…

Many colleges and universities recently piloted and adopted the co-requisite model of delivery of developmental mathematics while offering more options for students to fulfill their mathematics requirement. We discuss our process for piloting and ultimately implementing the co-requisite model at our university, provide preliminary data on student…

The Mathematical Association of America's "Precalculus to Calculus: Insights and Innovations Conference" brought together representatives of mathematics departments from across the country with members of two national research projects to share and discuss both research findings and on-the-ground concerns of faculty. In this article, we…

Our university is one campus of the larger, 23-campus California State University system. In 2017, the Chancellor of the system discontinued the developmental mathematics programs at all 23 campuses. This caught us by surprise and compelled us to act quickly. This article gives an overview of our response, highlighting the change our department…

After serving multiple terms as department chair at a small, liberal arts college, we have had the opportunity to develop some insights in a variety of circumstances. Through these experiences, we have formulated some advice for current and future unit leaders. We have included some general transition advice and a "top ten list" of…

A Mathematics Department Chair plays many roles within the department and within the university as a whole. Facilitating the development and teaching of mathematics services courses requires working with mathematics faculty as well as members of other departments on campus. In this paper, we discuss many issues related to the Department Chair's…

Our department has experienced a significant culture transformation in its approach to teaching. This change is primarily the result of sustained focus on reforming two heavily coordinated sequences, Applied Calculus and Calculus. Initially catalyzed by pilot projects introducing a flipped-class format to these courses, the reforms led to broader…

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…
