Teacher of the Month-- |
Randall Cerveny, an Associate Professor of Geography since 1991 and creator of the ASU Storm Chasers, has traveled to every continent to learn more about the Earth's climate. This enthusiasm for his work places him in high estee m with students and others in his field. Royal Norman, Channel 3 staff meteorologist said, "He has always demonstrated a high degree of excellence in his work and is dedicated to his students and furthering their understanding of meteorology." Cerveny bel ieves he is obligated to inspire his students. "If an instructor fails to interest a student, the instructor has done a disservice to the student and the profession," he said.
I believe enthusiasm is one of the most critical aspects of successful teaching. If an instructor fails to interest a student--if that instructor is unable to motivate a student--then it is likely that student will not succeed and the instructor has done a disservice to the student and the profession. Motivation is particularly pertinent in an academic discipline such as Geography where there is an extremely limited number of majors entering the discipline as freshmen. In contrast to many subjec ts, the number of majors in Geography is directly linked to the interest that we instructors generate in our large lecture 100-level classes (Introduction to Physical Geography and Introduction to Human Geography).
Consequently, I have particularly focused my efforts in my 100-level classes towards the goal of promoting interest and excitement about Geography--and Meteorology, in particular. By bringing discussion of real-world events such as tornadoes, hurricanes a nd the greenhouse effect into the class, I strive to ignite students' own interest in the subject. My methods of instruction--video and slides of spectacular natural events, personal anecdotes, field trips and extracurriculum projects--all are especially geared towards promoting interest in Geography. I personally measure my success in achieving this by the number of students who switch their majors into Geography based on their experiences in my 100-level classes. To my satisfaction over the last eight y ears here at ASU, I have observed a larger and larger number of new majors in our discipline. I am particularly pleased at the increasing number of women and minorities in our program over the past few years--several of whom are now working for the Nation al Weather Service, private and governmental agencies such as Salt River Project and in graduate programs around the country.
In addition, I and my colleagues have recently attempted to reach beyond the level of our 100-level classes to promote excitement and interest in Geography. We have given teaching inservices at many local grade and secondary schools, set up displays at university functions such as the ASU Superbowl Experience and ASU's "Super Science" day, and developed strong connections with the local media (up and including having our Geography graduates and students working at local television stations as meteorolog ists). I also feel fortunate to have been appointed as a contributing editor to Weatherwise, an educational magazine dedicated to promoting public interest in weather and meteorology.
Practicality may seem an odd component of my teaching philosophy but it arises due to the nature of training required for our specialty program in Climate and Meteorology of which I am in charge. The requirements of our program are based on the s pecifications of the National Weather Service. In other words, in order to work for the National Weather Service, our students must fulfill a tough set of courses in mathematics, physics and meteorology. Consequently, I strive in my teaching (a) to give o ur students a rigorous caliber of instruction of that will give them the ability to compete successfully for jobs against students from other universities, (b) as much as possible, to give them the opportunity for "extra" training and experience that will give them additional leverage when competing for jobs, and (c) to incorporate the recommendations of former students working as professional meteorologists (with whom I strive to keep in contact) to improve and update my courses.
With regard to the second point, on my own time and contributing my own money, I have developed a major program--now in its eighth year--between ASU, the National Weather Service, and the local media called the "Arizona Thunderstorm Chase Project." This p roject has our ASU students acting as "mobile eyes" for the National Weather Service during our summer thunderstorm season, the monsoon. I am pleased to find that this experience has (a) motivated our students by giving them hands-on experience, (b) have allowed our students to develop networking skills with their potential employers, and (c) been recognized in the primary technical journal of meteorologists, the Bulletin of the American Meteorological Society.
Promoting creativity is a facet of my personal teaching philosophy that I hold particularly dearNess is one of the most difficult to accomplish. However the effort is extremely worthwhile. It is my contention that the best students, the best grad uate researchers, and ultimately the best professors are those who maintain and stress creativity in all aspects of their work. Consequently, I make a determined effort to avoid rote-learning and, instead, encourage student to develop their own methods of learning and discover their talents. I personally make an effort to go beyond the normal and expected. For example, I have published, in addition to my fundamental research on computer climate modeling, a variety of professional articles on such odd topi cs as "the weather associated with prison escapes" and "why didn't Columbus hit a hurricane in 1492?" These articles have produced much local and national interest--and potentially new majors.
As an example of creativity in the classroom, one subject that I teach--weather forecasting--is a skill that is both a science and art. Although it increases the difficulty in grading students' abilities, I maintain frequent 'real-world, real-time' foreca sting exercises where students must take the same base information that the National Weather Service uses and, over the course of an hour or two, must develop real weather forecasts upon which they are then evaluated. As another example, rather than simpl y use historical examples in studying Climate Change, I have developed exercises that use the concept of a hypothetical world to encourage students to test and evaluate the concepts they have learned in a new and hopefully exciting framework.
These three objectives--creativity, practicality and enthusiasm--mark my personal teaching philosophy. Although the accomplishments of my students in their post-graduate careers and their lives in general is undoubtedly due to their own abilities and tale nts, their achievements give me hope that, at least to some degrees Shave been successful in meeting those objectives.
