The author thinks that the interactive computer instruction helped the school reduces their dropout rate, and make their graduates get some impressive achievements in college. The author also suggest all schools to adopt interactive computer instruction. I think the author's opinions have no persuasion. Here is my point of view.
First of all, the ineractive computer instruction was only use in three subjects, but the school dropout rate was counted by whole students in this school but that three subjects, so the rate couldn't show the effect by useing ineractive computer instruction. Secound, the editorial did not mentioned any other reason the affect the dropout rate, the ineractive computer instruction may not be the only thing that could affect dropout rate, the economic or poicy can also make some influence. Moreove, the author did not compare the performance of last year's graduates who reported impressive achievements in college and in high school. If the graduate has always got a perfect grade in high school, then the interactive computer instruction would not have too much effects to him. Also, the author did not say that these graduates took the three subject that use interactive computer instruction, so we cannot say there achievements were benefit by the computer instruction. At the last, all school have different conditions, so one school cannot means everthing to others.
According to my opinions above, I think the autor's opiots are untenable arguments.
