There can be several commentary lines depending on the length of your paragraphs.
The commentary sentences should not introduce any new evidence but rather work with the information that has already been provided by analyzing, interpreting, and expanding upon it.

This sentence contains analysis, interpretation, character feelings, opinions, inference, insight, reasons, or color commentator.

But like many formulas, with specific guidelines and structures, you may be tempted to ask the questions; or the Schaffer method definitely have their share of benefits as well.
With the Schaffer method in particular some features do stand out; which make it a desirable writing tool for students and teachers alike. Likewise, the placement of the commentary sentences after the concrete ones also indicates to students that it's necessary for them to evaluate or expand upon the evidence that they present and not to just leave it 'in the air' for the audience to decipher its relevance on their own.

Your conclusion statement should properly synthesize all of the information in the paragraph and relate back to the topic sentence.
The method is backed by Schaffer's own research on the most effective means of crafting an essay as well as the best techniques to use in order to generate high paper scores.
Schaffer's format ensures that each paragraph is fully developed by designating specific types of sentences, a set number for these sentences (5-8 to be exact) and a specific order when composing them.
