IPC: G09B7/04
Filed: 1988-07-04
Abstract: PURPOSE:To display exercises of difficulty corresponding to the learning level of a learner in order by selecting and displaying the exercises in a corresponding difficulty group made in order according to variation in the learning level decision value of the learner. CONSTITUTION:An exercise problem selection part 12 reads exercises in a corresponding difficulty group and their correct answers out of an exercise storage part 11 and stores them. A display part 13 displays the contents stored in a selection part 12 and the learner inputs answers to the displayed exercises from an input part 14. A correct/incorrect decision part 15 compares a learner's answer with the correct answer to decide whether or not the learner's answer is correct. A learning level decision part 16 increases or decreases the learning level decision value of the learner corresponding to the decision result of the decision part 15 and outputs difficulty corresponding to predetermined sections of learning level decision values to the selection part 12. Thus, exercises of difficulty corresponding to the learning level of the learner are displayed in order.
