"Data Driven Teachers"

How do you see yourself using data in your hypothetical classroom:
Data-driven decision making is a system of teaching and management practices that gets better information about students into the hands of classroom teachers. This is a system that I have yet to hear about in my educational career but is something that I instantly was attracted to. For as long as I can remember (coming from a student perspective) it seemed every year went by pretty smoothly and then boom, the last one or so of school my teachers always seemed super stressed (which stressed me out) and were throwing tons of work on us because some how we didn't accomplish as much as we were suppose to and goals were not being met.
I feel as though this DDDM could be a solution to this, what seems to be, annual problem with teachers. It seems teachers don't set realistic, timely goals and in result rush the students and fail at reaching certain expectations for the school year. If we as teachers can keep track of our daily progress and have a paper in front of us showing each of our students progress on multiple aptitudes i feel it will help us with our time management skills, enabling us to accomplish and succeeed in realistic goals.
In order to do this, I would incorporate the SMART goals in my classroom; creating a measurable baseline and target, specific time frames (very important, we don't want to be rushing ourselves and especially our students- unneeded pressure!), specificity about what is being assessed (keeping our expectations and guidelines clear), specificity about the method of assessment (making sure we keep it VARIED, all children have their own speciality in test taking methods we must be sure to incorpate them all to get a legitmate score), and find focus areas to improve weak areas and to guide for future actions needed to reach the learning target.
I feel as though if we as educators can incorpate all these STAR goals in our classroom we can have better time management, organization, and a bigger over all perspective on EACH of our students success in the school system.
