Barbra Melendez, Silas Bowman, Keith Erickson and Edward Swim have written an article called An integrative learning experience within a mathematics curriculum. The article was recently published online in Teaching Mathematics and its Applications. Here is the abstract of their article:

We developed four separate scenarios focusing on the connections between mathematics, biology, and social sciences. This structure facilitated the coordination of faculty from seven academic departments on campus. Each scenario had students from different majors build mathematical models, gather information from their respective disciplines, and develop a final presentation that included a committee consensus on how to approach the problem in a practical way. As a result, students learned how mathematics plays a role in other disciplines and how insight from different points of view affects the approach taken to a complex problem.
