Providing Criticism in a Constructive Manner
Explain your understanding of the review paper by using phrases such as “From what I understand, the main focus in this section is...” This way the author won’t take your opinion as an attack or misinterpret the point you’re making, or think you're a know-it-all.
Ask the author to clarify any areas you don’t understand. You could ask questions like, “What is the purpose of this section?” or “Why is this example important?”
Point out areas that seem unrelated or unnecessary to the topic, why some passages don’t fit into the paper and if any information provided isn’t supported. Instead of just saying something is "wrong," explain why it is and give examples of ways to correct it.
