Present Perfect Exercise Glitch

Today, I met with a beginning level ESL student. Her homework for the weekend included a cloze exercise (a "filling in the blanks" exercise) using the Present Perfect. Before we started correcting the exercise, she asked me if all the blanks were supposed to be filled in using the Present Perfect. I said, "yes." When we started going over the answers, I realized that the exercises actually required using either the Present Perfect or the the Simple Past. Oops.

I apologized profusely to the student for giving her the wrong instructions. However, we were able to make the corrections together and this turned out to be another learning opportunity. I was also able to see her thought processes in determining whether the correct verb tense was the Present Perfect or the Simple Past.

I got the ESL grammar exercise from one of the of the sites that I use regularly for exercises. (I had copied and pasted it to Microsoft Word on my laptop (giving all the appropriate credit to the website).) It said that the exercise was for the Present Perfect. Other exercises specified other tenses, so I made the assumption that the whole exercise labeled "Present Perfect" was only using the Present Perfect.

This is not the first time I discovered an error in an ESL lesson I got from the Internet. Moral of the story: review the exercise before you assign it to your student!
