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.”
Discuss how well reasoned . . . etc.
Argument, as part of newspaper editorial, argued to use greater portion of available funds to buy more computers and to adopt interactive computer instructions throughout the curriculum. In order to bolster its claim, argument cites the example of Nova High School which started using interactive computer instructions two years ago and experienced decline in dropout rate immediately along with some impressive achievements by last year's graduates. However, because of several reasons discussed in subsequent paragraphs, this evidence offers dubious support for argument's conclusion.
First, by asserting that last year's graduates reported "impressive achievements" in college after introduction of interactive computer instruction in three academic subjects, argument seeks to establish a causal relationship between impressive achievements of last year's graduates in college and introduction of interactive computer instructions in three academic subjects. However, it is not clear that whether the impressive achievements by graduates were in these three academic subjects or in some other field such as sports. If the impressive achievements of graduates were in some other non-academic field, then interactive computer instruction program was definitely not accountable for these achievements. Since the evidence presented is open to divergent interpretations, it fails to make a convincing case for argument's recommendations.
Second, evidence cited involves ambiguous language. For example, argument states that school dropout rate "declined" immediately after adoption of interactive computer instruction. This is an indefinite word. The word "decline" might mean 50% decrease in dropout rate. Alternatively, the word "decline" might denote decrease of only 1% in dropout rate, and to incorporate interactive computer instruction, which, presumably, is a money intensive program, for such a mere decline in school dropout rate is certainly not justified.
Third, even if students at Nova High school have benefitted from interactive computer instruction, argument unwarrantedly assumes that students at Nova High School is typical of those at all schools in district. Consider the example of some public funded school which mainly provides education to economically disadvantaged students who do not even possess basic computer knowledge. Such students may not be receptive to computer based learning at all, and introducing interactive computer instruction perhaps is not advantageous for such students. Since Nova High School cannot be representative of all schools in the district, conclusion drawn on the results observed in Nova High School is just an overstatement.
In summary, argument is substantially flawed and is neither sound nor persuasive. It fails to convey any compelling reason for schools in the district to adopt interactive computer instruction throughout the curriculum.
