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.
