Abstract

Abstract An educational aid comprises a display device for holding a plurality of information-bearing elements in an upright position. Each information-bearing element has a question and an answer on a first face thereof. The display device reveals the question to a user of the educational aid while concealing the answer. The user views the question and formulates an answer. He then removes the information-bearing element from the display device, and the question and the answer are revealed simultaneously. This allows him to easily mentally associate the question with the proper answer. Displaying the information-bearing elements in an upright position allows a number of students to simultaneously use the educational aid.
