Last November, a patent was granted for a pyrolysis method for increasing limonene oil produced from waste tires, and a novel oven to facilitate that method. This allowed him to study the chemical mechanisms of how scrap tire waste decomposes when heated. The patent was authored by Hanson and two students, James Haworth , Des Moines, and Tim Burrell , Cedar Falls . A prototype was constructed and proved to have improved operational characteristics, including better resolution and selectivity.
Students teach in student teaching centers throughout the state, the nation and the world.
The purpose of student teaching is to provide a planned, carefully supervised learning experience that allows the student teacher to demonstrate resourcefulness and competence as a teacher in a real school setting. The program allows the student teacher to also improve this resourcefulness as a teacher. Under the leadership of an experienced classroom supervisor, the student teacher's tasks include evaluating pupil progress, participating in extracurricular school activities, working with special area consultants, utilizing school and community resources, and analyzing the teacher-learning process. Student teachers are also supervised by student teacher coordinators who make classroom observations, evaluate the student teachers' progress and conduct seminars on a regular basis. The coordinators are usually permanent residents in the student teaching center areas.
