A learning system according to one aspect of the present invention presents a problem to a learner, receives an answer to the problem from the learner, and after answering is complete, presents the correct answer for the problem to the learner. If the answer from the learner to the presented problem is incorrect, the learning system acquires brain wave measurement data from when the correct answer for the incorrectly answered question is presented to the learner, and calculates the strength of a feedback-related negative electric potential from the acquired measurement data. In accordance with the calculated strength of the feedback-related negative electric potential and the incorrectly answered problem, the learning system acquires a problem to present next.
