Teaching Philosophy


Learner-Centered Teaching

This course will be taught according to the philosophy of learner-centered teaching. The key to this philosophy is to shift the focus from the contents of the course to the students' learning. For one thing, this means that we will not only discuss the material of the course, but also the process of learning itself; the true goal is to enable you to become self-directed learners with good critical thinking and self-assessment skills. To move into this direction, it is apparent that the students will simply need to try to do more of their own learning and that the instructor will need to provide something quite different than a lecture presentation in class.

Concretely, the appearance of the contact hours in class should be those of a seminar, in which every student is responsible for preparing himself or herself for the class discussion by doing the 'assigned reading.' We will then use the valuable time in class to focus on the reflection about and discussion of the material. In addition, we will want to spend some time discussing learning techniques and strategies; making these explicit is an integral part of learner-centered teaching, because it helps you develop those skills needed for self-directed studying of any mathematical contents beyond the material of this class.

Learner-Centered Teaching and Coverage of Material

Which brings us back to the material of this class. The topic of this class is the numerical solution of partial differential equations, applied to linear prototype problems of three classical types of second-order partial differential equations (PDEs): the Poisson problem for elliptic PDEs, the heat equation for parabolic PDEs, and the scalar transport equation for hyperbolic PDEs. Since this class does not have any prerequisites of PDE theory, we will start by defining PDEs as such and by discussing the most relevant properties of the solutions of the prototype problems. Then we will study the two most important types of numerical solution methods: the finite difference method (FD) and the finite element method (FEM). My goal is both to establish the basic convergence results for each method rigorously and to teach you how to use relevant software for these methods most effectively. There are clearly many more details associated with programming than one could fit into one semester. So, the focus will be on those skills that will enable the student to approach research in this area.

Clearly, these learning goals are 'visionary' for a one-semester course. But I believe that by applying the philosophy of learner-centered teaching, we will not just be able to meet these goals, but we should also find time and opportunity to talk about other important topics in class. Examples of those might be professional development issues of peer-assessment or techniques of teaching. To put this more concretely, consider the placement of this class in the curriculum: It is a second-year graduate course, and you are in the transition from traditional first-year courses to independent research with qualifying exams or thesis defenses; this course intends to help you in this transition. Another example of an appropriate topic for class discussion are the homework assignments. This is the level of class, at which there is more than one correct answer. So, it should be very profitable to discuss solution strategies in class. This should also ensure that your overall time-commitment for this class does not exceed the expected level of three hours of your own time for each contact hour. That is, compared to a class taught in traditional fashion, you should spend more time in preparing for class and less time on homework.

More Information

I hope these remarks give you an idea of the approach that we will take in this class. Feel free to ask me questions about it. I am convinced that it will be an exciting experience for you and me. For more information on learner-centered teaching, I highly recommend the book by Maryellen Weimer on Learner-Centered Teaching: Five Key Changes to Practice (Jossey-Bass, 2002). See my list of recommended literature on my homepage for additional resources on learning, teaching, and other professional activities (presentations, writing, etc.).
