One day a teaching intern asked me for some advice about a listening-skills class that she was struggling with. Her internship was for three-month, and she had been assigned to our ESL program. The lesson in the textbook for the class didn’t seem to address a skill that the students needed, but she had an idea for an exercise. However, she didn’t know if she should spend an hour or two or more developing a more relevant activity. Then she added this: “The professor in my TESL Methods class told us that we shouldn’t spend time writing exercises during our internship unless we know that we’ll be able to use them in the future.”
It made me want to cry.
The most obvious reason why this advice is so wrong is that none of us in the field of Teaching ESL can know when an exercise will come in handy in the future. But, besides that, there are more paramount reasons for teachers to write exercises.
