In this study, we attempted to derive the "flow" and "rhythm" inherent in educational methods by using the intersection point group(IPG) data assuming the line of sight from the direction information of children in a group, as a trial for the development of technology to visualize educational methods. We applied a probability distribution modeling and Fast Fourier Transformation to IPG data that is annotated with an early childhood education video. As a result, a specific distribution pattern was observed in IPG as the three time intervals where characteristic changes in IPG distribution occurred. In addition, the similar frequency components were found in the distribution of IPG in the same time interval. When these results were compared with the qualitative evaluation of the instructional plan, it was confirmed that the "flow" of the activity design and the "rhythm" of the teacher's action in the educational method were related to the characteristics of IPG distribution. These results suggest that it is possible to visualize the "flow" and "rhythm" of educational methods from the IPG analysis.
