Afterword to the Edition
The advisors of the international PBL during the past year were impressed of how the students of any country obtained a very positive developing of each subject.
I heard that it was not so easy for them to put forward the assignments in collaboration with the other members of each group, but every of them had the confidence to accomplished and developed the projects by themselves.
Additionally, it was the first experience of the PBL class also for their teachers' assistant, so their support for the students might have been insufficient. However, it is expected that such a project will be continued and improved year by year so there would be a good chance that the students would enhance their international senses.
