A line of communication is opened between the teacher and students. Teachers get to know their students much better. They get to know their students' personalities, problems, accomplishments as well as any extenuating circumstances behind poor student performance. This technique can be used in large classes to obtain quick feedback in a short period with limited effort well before using an exam. Similarly in part two questions may be requested about a specific topic instead of left general.
Students work in pairs and exchange their papers in order to compare and discuss their responses.
They might try to answer each others questions. This idea can be extended to groups of 3 or more students 3. Students individually or in groups could suggest questions and then analyze the collective responses and present the results to the class. Add any additional comments about your performance to date or other aspect of the class which has been on your mind. Constructive criticism as well as positive comments or helpful observations are welcome.
