Students will give more direct and honest answers if they feel they will not be judged or penalized by expressing their opinions and feelings. When students become familiar with this form of self assessment and learn to trust the teacher's response you can ask for signed papers. The primary advantage of a signed paper is that the teacher can respond directly and privately to individual students. A transition might involve making signatures voluntary for those students who wish a specific response. The purpose of this exercise is to encourage students to reflect on the class and review and synthesize what they learned before they leave the class.
Most classes end when the teacher has finished lecturing.
It is an abrupt end causing students to focus on their next class or activity, virtually blocking out the material they have just covered. The next time they look at the material occurs when they start their homework. To have students summarize and synthesize the concepts covered by describing them in their own words. Teachers can then determine if students have understood the concepts covered in class. Students review and focus on the most important ideas covered during the class.
