Teaching has been one of the most rewarding aspects of my career. My teaching philosophy centers on a behavioral approach to instruction and learning. First, I arrange contingencies that increase the likelihood that the students will continuously contact the assigned material. I have accomplished this by arranging frequent assessments related to the readings and lecture material. Second, I provide clear learning objectives for each instructional unit. I believe that there should be no “surprises” when it comes to evaluating my students understanding of the assigned material. Third, when possible, I arrange group activities that allow students to demonstrate the procedures discussed in the readings and lectures. Finally, I provide students opportunities throughout the semester to share anonymous feedback regarding my teaching style and class structure.
