A new study shows that students learn much better through an active,
iterative
(反复的) process that involves working through their misconceptions with fellow students and getting immediate feedback from the instructor.
The research was conducted by a team at the University of British Columbia (UBC), Vancouver, in Canada, led by physics Nobelist Carl Wieman. In this study, Wieman trained a postdoc, Louis Deslauriers, and a graduate students, Ellen Schelew, in an educational approach, called "deliberate practice", that asks students to think like scientists and puzzle out problems during class. For 1 week, Deslauriers and Schelew took over one section of an introductory physics course for engineering majors, which met three times for 1 hour. A tenured physics professor continued to teach another large section using the standard lecture format. The results were dramatic: After the intervention, the students in the deliberate practice section did more than twice as well on a 12-question multiple-choice test of the material as did those in the control section. They were also more engaged and a post-study survey found that nearly all said they would have liked the entire 15-week course to have been taught in the more interactive manner.
"It"s almost certainly the case that lectures have been ineffective for centuries. But now we"ve figured out a better way to teach" that makes students an active participant in the process, Wieman says. The "deliberate practice" method begins with the instructor giving students a multiple-choice question on a particular concept, which the students discuss in small groups before answering electronically. Their answers reveal their grasp of the topic, which the instructor deals with in a short class discussion before repeating the process with the next concept.
While previous studies have shown that this student-centered method can be more effective than teacher-led instruction, Wieman says this study attempted to provide "a particularly clean comparison...to measure exactly what can be learned inside the classroom." He hopes the study persuades faculty members to stop delivering traditional lectures and "switch over" to a more interactive approach. More than 55 courses at Colorado across several departments now offer that approach, he says, and the same thing is happening gradually at UBC.
单选题
The results of the research reveal that ______.
【正确答案】
A
【答案解析】[解析] 细节题。文章第二段第五句指出The results were dramatic: After the intervention, the students in the deliberate practice section did more than twice as well on a 12-question multiple-choice test of the material as did those in the control section. 由此可知在“刻意练习”组(deliberate practice)即实验组的学生成绩更好一些。故选A。

What do we know about the study led by Carl Wieman in the second paragraph?
【正确答案】
C
【答案解析】[解析] 细节题。根据短文第二段中in an educational approach, called "deliberate practice"可知选项C正确。选项A在文中没有提及；根据took over one section of an introductory physics course for engineering majors可知选项B错误；根据...teach another large section using the standard lecture format可知选项D错误。故选C。

How does Wieman look at the traditional lectures according to the third paragraph?
【正确答案】
A
【答案解析】[解析] 细节题。短文第三段第一句指出“It"s almost certainly the case that lectures have been ineffective for centuries. But now we"ve figured out a better way to teach”即几乎可以肯定的是几个世纪以来讲座一直都很低效。不过现在已经找到了一种更好的教学方法。由此可知，选项A正确。

How does the "deliberate practice" method work?
【正确答案】
C
【答案解析】[解析] 细节题。文章第三段最后具体讲述了“刻意练习”法。由The "deliberate practice" method begins...before repeating the process with the next concept可知“刻意练习”法主要是指老师在讲解概念时使用同样的方式。故选C。
单选题
We learn from the last paragraph that Wieman"s new approach ______.
【正确答案】
C
【答案解析】[解析] 推断题。文章最后一段指出He hopes the study persuades faculty...55 courses at Colorado...offer that approach...the same thing is happening gradually at UBC. 由此可推断，Wieman提倡的这种新的教学法正逐渐被一些大学接受。故正确答案为C。
