教育报道 - 填鸭式授课与互动式教学孰优孰劣?

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.

该研究在学年最后一个星期进行。一个班级继续按传统教学方式授课。另一个班级的授课教授由两名教师代替,这两名教师几乎没有教学经验,但接受了互动式教学方法的培训。这项培训由诺贝尔奖获得者、物理学家卡尔·威曼(Carl Wieman)执导。

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.

College students in interactive classes score higher on tests than those in traditional lecture classes, according to a new study.

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.”


Afterward, both classes took the same test. Students in the interactive class scored nearly twice as high as those in the traditional class. Attendance also increased that week.


Graduate student Ellen Schelew was one of the teachers. She says the methods they used are designed to encourage students to think like scientists.

研究生艾伦·谢卢(Ellen Schelew)是其中一名教师。她说她们使用的这种教学方法的目的是鼓励学生们像科学家一样思考。

ELLEN SCHELEW: "Their brains are turned on. They’re thinking hard and they’re really working through these problems. So even if they don’t have enough time to complete a given problem, they are prepared to learn from the instructor feedback that always follows groups’ tasks."


The study appeared in May in the journal Science. It seems to confirm earlier findings about lecturing to large classes. But some experts have criticized the way the study was done.


Both of the researchers who taught the class, Ms. Schelew and Louis Deslauriers, were also authors of the study. This could raise questions about whether their involvement might have influenced the results.

授课的两名研究人员谢卢和路易斯·德斯劳里尔斯(Louis Deslauriers)也是这份研究论文的作者。这会引发人们的质疑,他们参与其中是否会影响研究结果?

Professor Wieman is currently on leave from the University of British Columbia and the University of Colorado. He is the associate director for science in the White House Office of Science and Technology Policy.


He says research has shown better ways to teach based on evidence about how the brain learns. And he hopes more professors will learn that how someone teaches may be more important than who does the teaching.
