As Michael B. Horn reports in Education Next, a recent study of school districts using the blended learning model admit they don't use the student achievement data reported through the blended learning program. In fact, one school district admitted to not even knowing how many students they served in their dropout recovery program.
Software developers have gone to great lengths to incorporate high tech, detailed achievement data capabilities into blended learning programs. In real-time, teachers can see how their students are performing and know exactly which standard or component they don't understand. This allows the teacher to address the deficiency immediately.
But not if the teacher doesn't know how to use the data behind the software or doesn't have someone to support him/her in effectively using the data gleaned from the student's work.
