Education is what survives when what has been learned has been forgotten. – BF Skinner
Sometimes it’s a great way to show appreciation to teachers by highlighting the long-term value of their/our work.
The process, the intangible, the unmeasurable aspects of education often far outweigh the concrete. It’s usually these things that attract teachers to the profession. It’s usually these things they pour their hearts into.
It’s these things, for which teachers deserve our appreciation.
