Teachers are drowning in data and much of this data has little value to inform and improve instruction. Scott and Matthew Courtney discuss how to solve this problem- and do so simply and without wasting valuable time. Matthew Courtney is author of the book Exploratory Data Analysis in the Classroom and he shares how to effectively choose useful data (that teachers are probably already collecting anyway) and manipulate that data to help make real, meaningful instructional decisions. And this can be done without buying any software or taking a class in multivariate statistics: these are accessible processes that any teacher and any team can use and immediately begin developing a culture of instruction that is richly data informed.
