4月GMAT作文机经：互动计算机指导会不会降低辍学率

　　【原始】

　　坐稳，说一个某个高中引进了computer interaction的方式来促进基础课程教学。之后学校的dropout降低，毕业生在大学的performance也提高。然后就argue下一年的budget要大部分放在买更多的computer上，而且同一地区其他的学校也应该开设这种教学模式。

　　题目不难，很多地方可以找漏洞

　　【原文】

　　The following appeared as part of a newspaper editorial:

　　“Two years ago Nova High School began to use interactive computer instruction in three academic subjects. The school dropout rate declined immediately, and last year’s graduates have reported some impressive achievements in college. In future budgets the school board should use a greater portion of the available funds to buy more computers, and all schools in the district should adopt interactive computer instruction throughout the curriculum.”

　　【参考思路】

　　False Casual relationship:

　　退学率和毕业生成绩与计算机指导无因果关系。

　　(可能是学校出台的policy要求老师上课认真，学生更加勤奋导致的;stricter discipline applied last year;还有其他的比如加入新课引起学生的兴趣等等。)

　　All things are equal;

　　两年前结果不能用于未来(这两年来学校人事变动很大)

　　False analogy;

　　N高中与这一区所有学校无可比性。

　　(比如，其他的学校情况跟这个不一定相同。比如很可能是艺术类等文科院校，而这个是科学类的，所以不同;可能是这些课程适合转化成交互式，但是不是所有的课程都使用转化成电脑交互式的，或者转化成交互式不一定会有这样好的结果。)

　　Insufficient sample:

　　Nova这个一个学校不具有代表性

　　【参考范文】

　　The argument that the school board should buy more computers and adopt interactive computer instruction is not entirely logically convincing, since it ignores certain crucial assumptions.

　　First, the argument assumes that the decline of school dropout and the achievements of last year's graduates' results from the adoption of interactive computer instruction. however, there are several reasons why this might not be true. for example, achievements could have been made in other subjects than the ones with interactive computer instruction. or last years' graduates might not have been given the interactive computer instruction. or the decline of the rate of dropout could be attributed to stricter discipline applied last year.

　　Second, even supposing the nova high school's decline of the dropout and last year's graduates' achievements benefit directly from the usage of interactive computer instruction, the success of the instruction in one school may not ensure the success in other schools. if it does not suit other schools, the instruction will not work.

　　Finally, even if the decline of the rate of dropout and the achievements of the last year's graduates' are the direct results of the interactive computer instruction, we still do not know whether the school can afford to apply the instruction on all the subjects or to all the students. if the school does not have sufficient fund and has to cut budgets on other projects such as the library, the quality of the school's education will also compromise. thus, the argument is not completely sound. the evidence in support of the conclusion that the dropout rate declined and last year's graduates made impressive achievements does little to prove the conclusion-that other schools should use a greater portion of their funds to apply the instruction-since it does not address the assumptions i have already raised.

　　Ultimately, the argument might have been strengthened by making it clear that the decline of the dropout rate and the achievements of the graduates are the direct results of interactive computer instruction, that the instruction is also applicable to other schools in the district, and that the instruction is affordable to all the schools in the district.
