Passage 1 Results showed that at least a tenth of the Harvard first-year undergraduates polled admitted to having cheated on an exam prior to starting at the university, while almost half admitted to cheating on their homework. An anonymous survey by Harvard's newspaper has revealed a surprising pattern of academic dishonesty among studertts entering the US universities. The survey by The Harvard Crimson was emailed to the incoming first year undergraduates; 1,600 students responded. Results showed that at least a tenth of the students polled admitted to having cheated on an exam prior to starting at the university, while almost half admitted to cheating on their homework. Athletes were apparently the most prone to cheating. 20 percent of students who played a university sport admitted to cheating on an exam compared to 9 percent of students who did not. The survey also revealed that men were not only more likely to cheat but were also more likely to admit to it. The results, compared to a previous survey done on the class of 2013, suggested that cheating may be becoming more commonplace. Of the outgoing seniors only 7 percent admitted to cheating in an exam and another 7 percent said they had been dishonest on a take-home test. 32 percent of the seniors said they had cheated on homework during their undergraduate years. The surveys come in the wake of a cheating scandal at the university which saw 120 students investigated for sharing answers on an exam in 2012. One recent graduate stated: "Cheating was commonplace when I was at Harvard, especially with students in their first year or two. I would say as many as 60 per cent of students took notes into some exams. No one really cared the faculty, well some of them at least, seemed to recognize and yet ignore the problem." In an email to NBC News, Jeff Neal, a Harvard representative, explained that a committee, made up of faculty, staff and students had been established to tackle cheating, which "is a national problem in American education". He added: "While the vast majority of Harvard and other students do their work honestly, beginning this year Harvard College has implemented a new, more robust strategy of communicating with all students, particularly first-year students, about the importance-and the ways to achieve- academic integrity." In a rebuff to critics who say university has become little more than an expensive party, 84 per cent of the responding undergraduates fully expected to prioritize their academics over extracurricular activities, sport, employment and their social lives. Not a single student put academics at the bottom of their list. Not content with confining themselves to their degree subject, 59 percent of incoming students expressed a desire to pursue a secondary field of study, and 36 percent hoped to learn a language.

案例:“三角形中位线定理”是八年级学生的学习内容,下面是两位教师的教学片段:
教师甲:
在讲授中位线定理这一内容时,利用“数学软件A”作了两次测量,一次是验证三角形中位线定理,另一次是验证顺次连接四边形的中点所围成的图形为平行四边形。教师甲发现,当他让学生动手测量的时候,有一部分学生懒散地坐着,没有刚开始接触该软件时那样积极,课后教师向几位同学询问情况,有学生说这两道题书上都有结论,早就看过了,再去测量是不是有点儿傻?
教师乙:
教师首先让学生探究问题:如图1,五边形ABCDE 中,点
点 F、G、H、I分别是AB、BC、CD、DE的中点,J、K分别是FH、GI的中点,AE与JK有什么关系?学生们马上打开“数学软件 A”进行测量,很快发现AE=4JK。
能不能证明发现的结论呢?学生们没有一点头绪。
教师提示说当遇到问题解决不了的时候,我们是不是进一步先解决容易的问题?教 师引导学生去研究三角形中位线定理和顺次连接四边形中点所围成的图形是平行四边形两个问题,经过师生的共同研究,取AD的中点L后,学生不仅验证了AE=4JK,而且高兴地发现AE和JK还存在平行关系,如图2。
