ABSTRACT:
This invention provides immediate feedback to students as to their correct and incorrect responses by the incorporation of: a computer; electronic visual and/or audio feedback means; and a holding frame that contains a printed instructional sheet that is located above two sets of electroconductive strips, where the first set is located at a 90.degree. axis with the second set, and overlies the second set in a different but parallel plane. The centers of the conductive strips form the vertical and horizontal coordinates of a grid pattern. The instructional sheets contain response areas that are located above some of the points of intersection of the coordinates in this grid. Each strip in the two sets of conductive strips is connected to the computer, and the computer is programmed to know which points of intersection are correct response areas and which are incorrect response areas. At least one set of conductive strips is flexible or elastic. The two sets of conductive strips are normally held apart until downward pressure is exerted at a response area. This downward pressure causes a switching action that indicates to the computer the exact point in the grid at which the pressure was exerted. The computer processes this information and sends immediate feedback to the student as to the correctness or incorrectness of his response, and stores this information in its memory for later feedback or analysis.
