As if someone where tapping me on the shoulder, I realize in the two blogs these past days on putting more love into education, while they discussed how teachers can express love, did not suggest how to get teachers who display greater love.
Hire them. When interviewing them, look for teachers with loving attitudes. Tell them what you expect, and ask them if they would be willing and comfortable acting in such a manner.
Train them. At least once or twice a year, explain to them how to treat the students, and how to love them.
