I had a beautiful EFL lesson plan ready to go: vocabulary, reading samples, practice activities, conversational practice...
Somehow, I can't explain how, there was a coup. They refused to do the lesson. All they wanted to do was learn how to write in cursive! It looks so much more beautiful than print, they all argued.
From a practical standpoint, I believe there is a lot of value in teaching ELLs cursive. Many teachers still write in cursive, or a half-breed of cursive and print. This can be almost impossible for my students to read. (All caps is also a great challenge.)
So I threw out the lesson for the day and we learned cursive. (A moment of silence, please, for the death of my beautiful lesson plan.)
