Critical Response to An Editorial on Class Sizes in School. Ivanna Voitsekhovych

The topic sentence starting the paragraph clearly describes author's point of view: "the greatest problem facing public schools is large class size." But then we see many more unnecessary sentences. They ruin the structure pattern and deteriorate reader's impression. This contrast-comparative paragraph isn't balanced appropriately. There are only three features of the large classes against five features of the smaller ones. Although the points are precise, there are no supporting details to prove them. The author has great ideas, but he or she does not succeed in their arrangement. We did not notice many transition words that are really helpful for building up well-organized paragraph.
Also the writer did not stop where he or she should. The last sentence is not the concluding one. It would be better to finish with the previous phrase: "If the public school system were to cut class size in half, to approximately 15 to 20 students each, the benefits would manifest themselves immediately."
