Development of Scientific Skills via IYPT -- How does YPT participation lead to hard-skill development?

The Young Physicists’ Tournament (YPT) inspires high-school students to immerse themselves into an inquiry process closely resembling the real physics research. Using questionnaires’ replies from the students and their teachers engaged in YPT, we investigated how the preparation for YPT contributes to the development of hard - scientific - skills of the students, and how it compares to regular classes and other activities.
