We as teachers should notice the mistakes and errors our students make when talking.
Maybe we’ll write some quick notes while they’re speaking, for later correction.
I can tell you that for I’m a foreign or second language teacher, namely English, and I must notice my students’ mistakes and errors, and then go over them to correct them.
Then we can apply the PPP way of teaching a grammar form or pattern. PPP stands for Presentation of the grammar form by the teacher, then we have Practice and then Production of that form maybe into a communicative activity.
So remember: let’s notice the grammar forms that our students do not use properly and accurately. / Photo from: Cambridge PET
