Abstract: Printed matter is positioned behind a reflective and transparent surface. A lamp illuminates the printing. A student is instructed to copy the material on a typewriter. When a student begins typing, the lamp turns off and remains off until a predetermined interval after typing has stopped. The lamp relights, displaying the printed matter through the printed matter screen and when the student begins typing again the lamp turns off, hiding the printed matter. The process is repeated until the task is completed or a preselected time expires.The student is encouraged to type more during each successive interval, which encourages the student to remember words and groups of words and to comprehend.
