Buzz about big data notwithstanding, the interest in student data is hardly surprising. As we spend more and more money on higher education and as we struggle with college readiness and college competition (and student loan debt), there are more demands for us to be able to decipher some of what George Siemens describes as the "black box" of education. As it stands there is a great uncertainty about what actually influences learning outcomes. The promise of digital content is, in part, the promise to be able to glean more insight into learning. Being able to provide solid data about student progress -- what they understand, what they don't -- in real time and not just at the beginning or end of the semester, being able to provide remediation aimed at those strengths and weaknesses… these are powerful, powerful offerings.
