Information Technology (IT) in Teaching
The latest "buzz" in improving teaching is IT.  Some efforts are aimed at replacing teachers and books, but others are aimed at improving teacher/student interactions.  Projects of both types are being pursued within the Biology Department.
Randy Phillis, who teaches introductory biology using ClassTalk Technology, just returned from delivering a presentation at a Pew Center for Academic Transformation conference on IT in teaching.  At the conference both of the aforementioned aims of IT in teaching were presented.  Randy returned with many new ideas and a reassurance that the Biology Department is at the forefront of thinking with regard to IT and teaching.
The Massachusetts Board of Higher Education recently published a mandate on IT in higher education.  An included target is laptop ownership by every undergraduate.  While this may seem like a dream at the moment, the Biology Department is anticipating that eventuality.
Randy Phillis and Elizabeth Connor from Biology, Steve Goodwin from Microbiology and Adam Porter from Entomology have combined forces to use an innovative cluster of technologies in their teaching of Biology 100 and 101.  In this endeavor they are supported by our teaching technology expert Steve Brewer and the ClassTalk expertise developed in the Physics Education Research Group, headed by Bill Gerace.  Students come to class with their personal $100 TI calculators which they plug into the ClassTalk network.  During the lecture, small student groups are given problems to solve and the answers, accompanied by class results, are projected for the entire class to see and discuss.  Students are also encouraged via an online daily-updated web page to read the relevant chapters in the required text prior to lecture and to earn credits by successfully completing short online quizzes before class.  This allows class time to be spent in clarifying the information rather than exposing students to it for the first time.  In Biology 100 and 101, the use of IT does not result in a dilution of course content; the same amount of material is covered with more time spent clarifying concepts.
The ClassTalk approach will be extended in spring 2002 when Elsbeth Walker will use it to teach genetics.  Genetics would seem a natural course for this approach; it would be helpful to provide students the opportunity to solve genetics problems with the instructor at hand to help analyze responses and to provide reasons for the inappropriateness of certain solutions.
Randy reports that, at the Pew Conference, courses were described in which 50 or 100 laptops were connected with wireless technology to the course hub.  If groups of two or three students were to use one computer, then classes of 200 to 300 students could be accomodated.  The key to developing IT-supplemented pedagogy is to enhance rather than eliminate the role of the teacher.
Several other faculty have introduced IT into their courses.  Dennis Searcy has experimented with the use of an online textbook in his Cell Biology course.  This requires that every student have access to an online computer or terminal.  Currently, about 85% of UMass students own computers.  Pat Wadsworth reports that she has ceased to use paper handouts in her 400 student course, Biology of Social Issues; all visual materials are on the course website.  Use IT and save a tree!
