Teaching Philosophy

Too often, teaching is viewed as one of the jobs a university professor must perform. I choose to view teaching as a privilege and as the most important job a professor performs. Teaching takes on many different forms. It occurs in the classroom, office, and laboratory and it involves students and colleagues as well as oneself. Teaching may be structured, as it is in most classroom settings, or it can be largely independent where the teacher provides guidance and information as is typically done when overseeing research projects. Teaching may also be unstructured where the student and teacher work together, investigating and learning to simply broaden their horizons. To these ends, teaching involves the communication of knowledge. This communication is most effective when the student is actively involved in learning. To involve students, a teacher must understand the nature of students, how to adapt knowledge to interest them, and how to structure effective participation experiences. I am convinced that students are better able to comprehend and utilize knowledge when they participate in well-designed learning experiences. As a result of my belief that learning is understanding how to use knowledge, not simply memorizing facts, my teaching style emphasizes student participation. I choose to use a problem-based learning approach so as to challenge students to develop thinking skills appropriate to understanding the scientific material in my classes. The following describe some of the methods that I use. First, I strive to help students develop the ability to formulate and ask questions in class. This is a skill that many students simply don?t have. Exercises related to this have included writing questions for submission to magazines (several of which have been published), a required question submission component for my introductory class (the ?muddiest point? option), and developing a question and related hypothesis for semester research projects. Second, I permit open discussion in class. I encourage the students to ask questions regarding the material, question my thinking or rationale in my lectures, or offer personal insights related to the topics. Third, I plan small group (2-4 people) learning sessions in class where students work to solve problems or to discuss issues. This has included mathematical problem solving, hypothesis writing, and participation in team-oriented games. Finally, I require the students to communicate their knowledge in oral and written form. Beyond the traditional exams and assignments, each student will make a presentation to the class as well as turn in at least one formally written paper. Beyond participation, I believe that developing the link between concepts and application is an important aspect of teaching. I attempt to help students understand the integral role research plays in developing and utilizing knowledge. To help understand that process, students in my classes complete a semester long research project. Each student participates in a small group (2-4 students) to conduct a simple research project using the steps of the scientific method. They must formulate a question and develop associated hypotheses, collect data, analyze these data, and report their findings. I view these projects as an opportunity that most undergraduates do not receive, particularly in introductory classes. In this advancing age of technology, I feel that it is important to expose students to new technologies and to require students to gain experience with these technologies. One avenue for developing these skills is the semester research project. Students use state-of-the-art equipment in our laboratory to conduct human movement analyses. This work requires the students to acquire and use research and computer skills. Although a major time commitment on the part of the student as well as the teacher, this experience demonstrates to the student how the knowledge they are gaining in the classroom can be applied in the real world. Often the students begin their projects by believing that the questions they ask are mundane or too simple to be considered for a research project. After completing the project the students generally are much more aware of the time, effort, and care needed to conduct a research project. They have also developed a better understanding of the concepts presented in class. I use every opportunity to incorporate technology into classes. For instance, my lectures include the use of computer generated slides. This enhances my ability to present complex ideas using intricate graphics, equations, etc. in a systematic manner. I also require homework assignments using the computer. For example, one assignment pertains to using the internet to locate information specific to the topic of the class. Finally, a large portion of the class laboratory is conducted with the aid of technologically advanced equipment. Introductory courses often challenge a teacher because of the diversity of students? backgrounds, uncertainty in career choices, and, depending on the material, potentially intimidating information. To this end, it is necessary to remove any barriers the students may perceive in relating to me as a person early in the teacher-student relationship. I attempt to clearly describe my expectations of the students at the very start of our relationship. At the same time, I work hard to learn about the students in my classes. This information allows me to tailor the class to meet the students? needs. It is important for me to arrive early to class and to hold office hours immediately following class so that students can access me while questions are fresh in their minds. I believe that an ?open-door? policy is essential to establishing an effective communication link to students, and, I strive to be accessible for them at hours that accommodate their schedules. I also think that it is important to take an interest in the students? activities outside of the classroom. As a result, I try to attend various student events and talk with them about things that are important to them. Knowing the students and understanding their responsibilities is as important to me as for them to understand my expectations of them. In summary, I believe that to effectively teach my courses I must encourage the students to take an active role in their education. It is my responsibility as a teacher to develop participation in the class as well as provide effective approaches to learning the material. Success in these endeavors will produce students who have achieved an understanding of the field both in concept and application.

Research

Sport and Exercise Biomechanics

My interest in sport and exercise biomechanics focuses on swimming.  I am actively working in several areas within swimming with the underlying goal of understanding what factors influence performance in competitive swimming.  Specifically I am studying the effect of buoyancy on aquatic performance, the influence of biomechanical, physiological, and psychological factors on variability in swimming performance, the factors that best predict success in swim starts, development of stroke and turn characteristics with training, and the effect of equipment on swimming performance.

Neuromuscular Control of Movement

My interest in neuromuscular aspects of movement centers on the performance of bilateral and unilateral tasks under maximal and submaximal conditions.  Bilateral or bimanual tasks are an important aspect of everyday activities.  Evidence suggests that strength decreases in a given limb when that limb is activated simultaneously with the contralateral limb.  This is known as the bilateral deficit.  Much of this research has focused on investigating this phenomenon using maximal effort exertions but few if any activities are normally performed at maximal levels of exertion.  Therefore, I am investigating the existence of the bilateral deficit at submaximal intensities by studying the physiological and cognitive components of the bilateral deficit. 

An application of this work has been to study everyday bimanual tasks (e.g., sit-to-stand tasks) with the goal of developing approaches (training and/or techniques) that may reduce or eliminate the effect of the bilateral deficit.  Recent work has included work on balance training to improve proprioceptive function using novel training equipment.
