写的是学校留作业不超过一周两次的那个。写了40分钟，这是我第一次写额。。。。
提纲：
1.数学和自然科学不能代表所有的课程
2：两个学校学生成绩不同，不一定是由于留作业次数不同造成的
3：两个学校的情况不能轻易推及到州内所有学校。
4：总结
谢谢大家了，题什么样的意见都是被我珍惜的，而且，我这个是没有改过的，我正好还要改，请大家多多提意见啊！！！
This editorial recommends that all our high school teachers should assign homework no more than twice a week. To support this recommendation the editorial cites a statewide surveyof high school math and science teachers that in Marlee less than 25% of teachers reported assigning homework three to five times a week and the persentage of teacher in Sanlee assigning three to five times homework is 86 persent. However the students in Marlee have much better grades at study and are not that likely to be required to repeat a year of school than are the students in Sanlee. On the basis of this evidence the author infers that the less teacher assign homework the better the students learn in all schools statewide. This argument is logiclly flawed in several critical respects.
To begin with, the argument unfairly assumes that the result of survey on math and science teachers are able to show problems in all subjects in the high school studies. The editorail shows no evidence to substantiate this assuption. Lacking such evidence it is entirely possible that the other subjects in school need far more practice off class and also, the teachers of those subjects assign great amont of homework to ensure their class getting a good gread. The situation of one or two subjects can not represent the whole.
The argument also assumes unfairly that the schools in Sanlee and Marlee have a same degree in their teachers' teaching levels and students ability to maintain knoledge on a large scale. Even if the statics on math and science can represent a student's overall scores. Perhaps there are quite good students and also the same outstanding teachers in Marlee while in Sanlee there are just ordinary teachers and students. The grades overall should of course not be the same of this kind two schools. And to the extent like this, it is obviously not convincing enough to conclude that the less homework assigned the better grades students will get.
Even if the two cited school have same situations on students and teachers and the result of the survey that students been assigned less homework in Marlee prefrom better than students with more homework in Sanlee. But, since the editorial provides on evidence to substantiate that the rule also fits the other schools in the state. It is equally possible that there are schools in the states that have different criculums with schools cited in the editorial, obviously there might at all be differences in the strategies of teacher's assigning their homework. Thus without better evidence that the cited two schools can represent all the schools in the state, the editorial remains unconvincing.
In sum, the editorial's author cannot justify his or her rencommendation on the basis of the scant evidence provided in the editorial. To bolster the recommendation the author ust provide better evidence that (1) result of survey on math and science will fits all other subjects, (2) besides the differnence between times homework assigned in the tow cited school, no other factors effects the overall grades of students their and, (3) the situation in the two school will be able to represents all other schools in the state. To better assess the argument I would need to know the relatively ranking of the two cited school in the state and also the relavent statistics about the homework assigning situations in other subjects in the two school. |
