Through his efforts and with the help of outside agencies, the stu dents also have a pond on school property where they raise bass and trout.

Martin said he is proud of the fact that students built the facilties. In effect, the students built the classrooms and the teaching materials from which they leam. Rather than using strict lectur ing to drill concepts into the stu dents’ heads so they can pass writ ten tests, Martin’s teaching style is to provide instruction, and to let the information sink in as the proof of the lessons taught becomes apparent through observation and work. The potential for a student to surpass a teacher in knowledge “We’ve Got The Power.” about a subject is riiuch less, if the knowledge passed onto the student comes from a teacher who depends solely on on classroom lectures and tepts. The potential for a student to gain a solid grasp of a concept, and eventually discover new things, is much greater when a teacher’s theory is tested through application. “All the activities, including water quality work, calculations of feed rates, and application of sci entific principles give these vo-ag students new skills and the confi dence to try new things, which hopefully will carry over into their lives after graduation,” Martin said. Not only do the students get to raise fish from fry and plants from seed, but they also do maintenance work and record keeping.
