Abstract
The present invention is an electronic teaching system containing two principal components: a projection frame and a hand-held remote unit. The projection frame mediates the electronic test and holds a transparency on an overhead projector so that the transparency may be projected for an entire class to view. Typically the transparency features a series of questions and possible answers to the questions. The projection frame asks the questions and displays the results of the testing process. In a preferred embodiment the projection frame bears a series of pointers, one for each question. When a given question is asked, the corresponding pointer becomes illuminated. Students participate in the test by matching the correct answer to the appropriate question. The students use the second component of the present invention, the hand-held remote unit which bears a keyboard, to answer the question currently being asked by the projection frame. The hand-held remote unit and the projection frame are in wireless communication so that the projection frame is able to respond to the students'"'"' answers by indicating correctness of the answers and by awarding points for correct answers.
