Research indicates that students' learning performance can be improved through techniques of "action-feedback-correction," which involves the student answering questions, feedback on which answers are right and which wrong, and repetition of the process until the right answer is achieved. Such a system can easily be devised using objective practice exercises and standard answer sheets, on which incorrect answers are marked, but not corrected, before the sheets are returned to the student. Efforts should be made to ensure that students do not cheat; that they do not answer the questions until they have studied the assignment or read the material; and that the scoring, feedback, and correction parts of the process are carried out. Time can be saved through scoring the tests by machine, as opposed to by hand, although hand-scoring increases the link between student and instructor. Instructors can minimize the time spent in writing questions by focusing on the fundamentals section of the course, e.g., on key definitions, problem-solving techniques, and critical principles. The benefits of the action-feedback-correction technique include individualized instruction at low cost, a clear communication of learning objectives, improved student learning, and better monitoring of student progress.
