I can relate to this sentence because this happens with my 14 year old son. During parent teacher conference, his teachers always speak highly about his participation in class but that he falls behind when it comes to completing assignments in class. To them it seems that he is always in a rush to complete an assignment when he has trouble understanding what it is asking. I believe that there are students who need extra support from teachers. Assignments should be broken down for them and teachers should encourage students to ask questions when they don’t understand something.
