A common expression I often heard when I first started teaching was “Teacher, I don’t understand.” I would, of course, ask them which part they didn’t understand, and then give them further explanation. However, I would still see confusion on their faces. It was my turn to be confused. I had done what I was supposed to do, explain, but still they repeated “Teacher, I don’t understand.”

I didn’t find the answer until I had the chance to observe a student teacher. I had my ‘aha’ moment. The teacher was explaining vocabulary and expressions perfectly. However, she had barely considered her students’ levels and their level of understanding for the “perfect” explanations. At that moment, I realized my mistakes: 1) I treated them like their English was at my level; 2) I taught English like I was an ESL teacher.
