Argument61:
-------题目-------
The following appeared in a report by the School District of Eyleria.
'Nationally, the average ratio of computers to students in kindergarten through grade 12 (K-12) is 1:5. Educators indicate that this is very good ratio. This means that across the country, all students have access to and can use computers daily in their classrooms. In Eyleria's K-12 schools, the ratio of computers to students is 1:7. This number is sufficient to ensure that all of Eyleria's students, by the time they graduate from high school, will be fully proficient in the use of computer technology. Thus, there is no reason to spend any of the schools' budget on computers or other technology in the next few years.'
-------正文-------
The author concludes in the report that we need not to spend any of schools' budget on computers or other technology in the next few years. To support his claim, the author provides the national average ratio of computers possessed in the kindergarten toK-12 is 1:5 which is regarded as a very good ratio. With the ratio of 1:7 in Eyleria's schools, students still can master the ability of using computer well when graduating. After carefully analyzed, the argument has several flaws.
Firstly, the average ratio is not a clear statistical data. Perhaps in some developed districts of the nation, the ratio is very high such as 1:1, while in some developing districts it may be very low even approaches to 0 due to the level of economical development. Although educators consider this ratio very good, I still can not be convinced without any detailed and clear evidence.
Secondly, the author makes a mistake in causality. He holds the opinion that the so-called very good ratio let students can use computers daily in their classroom. Yet whether the reason that the ratio is good stand still remains testifying, how can we believe the result. Even if it is a good ratio, we cannot assure every student can use the computer. Perhaps someone always occupy the computers till evening--school is over, then others may not have chance to use daily. Thus, the author fail convincing us with his view.
Thirdly, there is another assumption in the report. In Eyleria's K-12 schools with the such ratio of 1:7, students will be fully proficient in the use of computer. This is maybe the specification in Eyleria. It is entirely possible that K-12 schools in that area provides more computer course for students to learn than other districts. Also, maybe in Eyleria more students have computer at home. So they have more chance to use them.
Finally, the author makes another causality mistake. The condition that students in Eyleria master use of computers better hasn't been justified, how can we state there is no need to spend money on computer in schools. Even it is true, we still cannot guarantee the whole nation has the same situation. It is also a false analogy. Yet the author hasn’t mention the situation about other technology in schools, therefore the author's another conclusion that it is no need to spend money on other technology is not persuadable. Perhaps many schools need to improve their equipment in education such as the multimedia teaching.
In sum, the argument cannot persuade us. To strengthen his assertion, the author should provide more detailed and clear ratio and the situation that students use the computers. Also, the condition of possession of computers at home should be state. We appreciate that the author offers us the information about students’ use of computer in other areas of nation. |
