摘要： A teaching apparatus comprises a unitary plate member presenting a flat, impenetrable upper surface having a plurality of holes therein representing correct answer selections, for example. A pattern of projections on the surface extends upwardly therefrom and receives an instructional sheet having zones thereon for indicating answers selected in response to questions, a stylus being employed by the student to indicate each answer by pushing the stylus against the selected indicator zone. The zones and the areas of the surface therebeneath are aligned so that the stylus meets the surface but does not penetrate the sheet beneath incorrect indicator zones, whereas openings are punched in those zones representing correct answers due to the presence of the holes. The projections, either spaced apart along the boundaries of the areas or formed as a continuous grid, prevent the student from feeling the holes and thereby anticipating the correct answers, but are limited in height so that the stylus penetrates the sheet only at the correct answer zones.
