Where I found it: While reading Donald Shcon's Reflective Practitioner. "Surely this is a laudable exercise in self-criticism.
Shcon, D. (1983). The reflective practitioner. USA: Basic Books, INC.
Definition: Merriam Webster defines laudable as "worthy of praise/commendable."
Here is the link.
Familiarity: Unfortunately, the word laudable was one of many that i did not understand while reading this book.
Reflective Commentary: I do not think this word, laudable, is too important to know, nor is it connected to teaching in any specific way. It's still a nice alternative to use when speaking of praise.
