Ask a Curmudgeon #1

Grandpa, you are an old teacher.  Why do old teachers reject new ideas?

Curmudgeon:

Most new ideas in education are old ideas with new names.  Old teachers want progress, not the ideas that did not work 20 years ago. Young teachers like these ideas because they did not experience their failure 20 years ago. In other words, they cannot be 55 when they are 35.
