This paper discusses about learning methods to overcome stress or pressure. We had an experiment in which learners were given a quiz game for each learner to need responsibility for their team. Each learner was also given learning time for the game so as not to make mistakes for their team, which was supposed a stressful learning situation. Before they had the experiment, they designed several learning methods to overcome the stressful situation and actually used the methods in the learning time. After the experiment, they discussed about effectiveness of their methods and made reports about it. The quiz game was provided as a mobile application running on a tablet device. The application recorded log data of their operation during the quiz game. We analyzed effectiveness of their learning methods by comparing contents of the reports as subjective data with the log data as objective data. The finding from the analytical result was that the learning methods giving a little stress or pressure to a learner brought out higher learning performance rather than the methods giving relaxation.
