Computer helps students learn physiology NEWARK, Del. -- Physiology and anatomy students have been memorizing the names and locations of the glands and muscles since time im memorial, but Dr. Paul Sammelwitz’ animal science students at the University of Delaware master the age-old lessons in a new way. Sammelwitz’ students supplement then* regular, classroom and laboratory work with Plato, the com puter-assisted learning system. Upon registration for Sammelwitz’ courses, Chillcuring works. DAN KOLB, Spring City, Pa. This is my third year with the Harvestall system, and I’ve found it to be ideal for my setup. I’ve harvested corn at 30% with no problem. The thing I ■ eally like about the Harvestall is that I don’t have to babysit a dryer. I can fill it and forget it. Plus there are really no major moving parts to wear out or break down. “I can cure down 26%-30% corn for around 6C to 8C a bushel. 24%-25% would run considerably less. “The way the Harvestall works is simple and effective. As for those who are skeptical, it’s like the bumble bee: according to scientists he’s not supposed to be able to fly. But he’s too dumb to know it, so he flies anyway. So regardless of what anyone says, the Harvestall system works. It works for me and I’m happy with it. I do recommend the Harvestall for its economy and for its considerable savings on energy." each student is assigned a regular time-slot with the computer. At the computer center each student faces a typewriter-like keyboard topped by what appears to be a television screen. When the student types the ap propriate code, the assigned lesson appears on the screen. First the student sees an unlabeled diagram of the human endocrine system, for example. As he or she pushes button A, the adrenals are located on the diagram. The student pushes «« Mg energy savings and ■ don’t haveto B and Plato 'points out the pituitary gland - and so on. Each student can take as long as he needs to master the lesson. When he feels he has the glands down pat, he can ask Plato to test him. This tune it’s up to the student to tell Plato the name of each gland on the diagram. If the student misses too many, Plato politely but firmly types out, “Suggest you go through this lesson again.” Project Plato is not new to the University. The system is used extensively by many ■ get babysit a dryer!* departments on campus, to teach such diverse subjects as plant science, mathematics, music and nursing. Sammelwitz himself has been using Plato with his students for the last four years. But up until this year he had to rely on lessons that had been programmed for veterinary students at the University of Illinois. While these adequately covered much of the factual material Sam melwitz wished to cover, much of the material was more detailed than necessry * The Harvested Chillcuring System It’s simple When gram comes out of the field it’s a living seed So instead of destroying the seed with high heat, mois’ture is removed with natural air ventilation. The grain keeps all its feed value; there is less shrinkage than with heat drying because only moisture is removed, not dry matter You’ll never see white dust in chillcured corn You actually save half of what you’re used to losing in heat shrink There’s no oil or gas to buy Natural air carries away heat and moisture as the corn releases it Harvestall Chillcuring is a “back-to-basics” system that just simply makes good sense Find out more about it Advanced Ag Products Box 174, R D 2, Elverson, Pa 19520 215-286-9118 for Sammelwitz’ freshmen and sophomores. However, the lessons did enable Sammelwitz to skip much of the rote memorization lessons in class, leaving more class time to explain how and why the body systems function as they do. Still, Sammelwitz wanted the material to conform better to his own lesson plans, so this year he took the matter into his own hands and designed several lessons specifically for his introductory level courses. So far he has programmed Lancaster Fanning, Saturday, April 28,1979 ♦ -0. ♦ 51 lessons on the endocrine systems of mammals and birds, he plans to cover the rest of the body systems eventually, but he says it will take years to finish the job. The students agree it’s a worthwhile long-term goal, since they easily notice - and appreciate - the im provement in the lessons Sammelwitz designs him self. Visitors will have a chance to try Plato for themselves at Ag Day, today, April 28 from 10 a.m. to 4 p.m. at Agricultural Hall in Newark. Sammelwitz will set up a computer terminal in the lobby of Agricultural Hall for the event, which also features live animals, pony rides, a plant sale, and fun and games for the entire family. Youngsters will be able to match wits against Plato in arithmetic, and the computer can evenshow everyone how a flower grows. Red Lion Area FFA winners named RED LION - The Red Lion Area FFA parliamentary procedure team captured first place honors in the Adams - Franklin - York Counties FFA area contest held at York Vo-Tech on April 17, while two Red lion public speakers placed 2nd and 3rd. The parliamentary procedure contest consisted of each team-conducting a business meeting and demonstrating their ability to use proper parliamentary practices in handling of assigned items of business. The members of the winning team were: Barb Snyder, Ken Sechrist, Darlene Schrum. Francine Lewis, Chris Reacbard, Greg Innerst, Blaine Grove, and Todd Grove. Marie Leavers placed second in the Conservation Public Speaking contest with a specch"entitled “Con servation - Use But Don’t Use Up” and Beth Holt zinger placed third in the FFA Public Speaking contest with a speech en titled “Agriculture’s in Your Future - Why Ignore It? ’ ’ The participants in this contest were those who advanced from the in dividual county contest. These winners will now compete in the Regional contest which involves competition from a 12 county area, to be held at Ship pensburgonMayl.
