Abstract
An electronic device for displaying question data and answer data includes an input device for entering commands, first and second displays, and a processor. The question data is displayed on the first display which is visible to an operator of the electronic device and on a second display which is visible from a position from which the first display is not visible, i.e., the position of an observer such as a student. The operator can selectively control the displaying of the answer data on each of the displays using commands entered on the input device. Entry of a first command causes the answer data to be display only on the first display so that the answer is visible only to the operator. Entry of a second command causes the answer data to be displayed on the second display so that the observer can also see the answer. In one mode of operation, the question and answer data for many questions is stored in a storage device, and the questions are categorized by level of difficulty or by subject. The operator selects the category of questions to be presented, and the question and answer data for each question in the category is automatically retrieved from the storage device for display on the first and second displays. The operator enters commands through the input device to display each successive question and to selectively control the displaying of the answer to each question on the first and second displays.
