How can data drive instruction?

Reviewing data like NETS quiz can help you as a teacher see where you are going wrong with instruction. If the students are struggling getting the idea from your question, then you may be writing it wrong. For example, our group looked at question 2, and we realized that the students probably don't understand what two of the options mean, and that's why over half of the class clicked on that choice.
I will definitely use data like this in my classroom because it is a check-up on how I am doing as a teacher, and if the students are learning from me. This is important because these students are going to be with me all year, so I need to be sure that I am an effective teacher for all of my students. Data like this can help me see the big picture. If just one student is struggling, then I can work individually, but if over half of my class is struggling, I need to fix my approach and figure out where my students are struggling.
