The way I cope with lexical errors in the classroom demands a lot of patience and delicacy, and also, I use aids in class, like cue cards with grammatical structures and vocabulary according to the topic of the lesson, so I can calmly ask the student to take a breath and look around, I do not provide them the answer, my intention is for them to find their error and corrected by themselves.
Grammar is one of the most difficult and tricky topics to teach in the L2 classroom, however, it is a good way to recreate a significant learning moment is to do an exercise of analysis among all the students, it helps the teacher to identify if there are any other students with the same problems and also to reaffirm the knowledge of those students that have comprehended the topic.
Correcting pronunciation errors is a very important part of teaching, especially in regards to the communicative approach. Pronunciation errors most of the time are influence by the student's mother language and are quite difficult to correct. It requires a lot of gesticulation, vocalization, and discipline. To give a correction to students pronunciation errors I try to use some technology like dictionary apps and also phonetic charts apps that help students not only to correct the error but to be aware of the "written phonetics"
