Six Steps To More Effective Science Teaching

Trim the curriculum Ronald Gillespie, a professor of chemistry at McMaster University in Hamilton, Ontario, is one of many teachers who noticed about 10 years ago that the 1960s trend of stressing physical chemistry concepts in introductory courses omitted inorganic, descriptive chem- istry. As a result, his students knew little about common chemicals. The solution in the United States and Canada was to put the missing topics back in--but the average chemistry textbook swelled to more than a ki

Gordon Uno, a biology professor at the University of Oklahoma in Norman, offers one increasingly common solution in burgeoning scientific fields whose content refuses to be crammed into an academic calendar: "Realize that you can't do it all. It's better to know a few things well than a lot of topics not well at all." One new biology text has sheared 200 pages off the typical 1,000 by substantially shrinking the diversity section, instead weaving in examples of different organisms in all chapters.

Another approach to handling the information overload is a "cap- stone" course in the senior year to tie together concepts learned in different courses. Or, simplest of all, a single course too packed with topics can be expanded to two semesters.

Separate out the majors At Babson College in Wellesley, Mass., business majors can take professor David Adams's "Chemical Technologies in the Manufacturing System." Through case studies, ...
