Lecture or Interactive Teaching? Old Issue, New Study
01 June 2011
College students in interactive classes score higher on tests than those in traditional lecture classes, according to a new study.
This is the VOA Special English Education Report.
Professors have lectured for centuries. But how effective is lecturing to students compared to working with them?
A new study compared two classes of a beginning physics course at the University of British Columbia in Canada. There were more than two hundred sixty students in each section. Both were taught by popular and experienced professors.
The study took place for one week near the end of the year. One class continued to be taught in the traditional lecture style. The other professor was replaced by two teachers. They had little teaching experience but received training in interactive teaching methods. The training was led by Carl Wieman, a Nobel Prize-winning physicist who leads a science education program.
There was almost no lecturing. The teachers put the students in small groups to discuss and answer questions. They gave them readings and quizzes to finish before class so they would come prepared to discuss the material.
Professor Wieman says before the experiment with these and other activities, test scores for both classes were the same.
CARL WIEMAN: "There was a great deal of careful data collected showing how identical the two sections, these two large sections of the class were beforehand. And this focused very much on looking at exactly what could be learned with the different methods from the classroom experience, the time when you have the maximum instructor interaction, or face-to-face interaction time.”
