This second part in an eCampus News series about the power and pitfalls of Big Data examines the criticism and skepticism surrounding the buzz words.
A university recently crunched all of the “Big Data” it had gathered on a course and made a surprising discovery.
Out of the two professors who taught the course, one had significantly lower performing students. But this was a professor who had won several teaching awards and was well-respected by campus leaders.
What was going on here, the researchers wondered as they sifted through all of the data points at their disposal.
They could only draw one conclusion based on the data at hand: the poorer student performance was because the professor was not the level of teacher everyone believed him to be.
The conclusion, it turns out, was wrong.
