Shigeno Yasuda cobbles together two different Japanese family names and, to someone not familiar with this fact, might look like the name of one person. If it is desired to associate Shigeno's name with the approach to teaching introduced by Yasuda at least make it Yasuda-Shigeno (Yasuda was first) or, even better, The Yasuda-Shigeno Teaching Method.
I agree and changed the name, for future reference Page Rename Requests.
