West sees teachers and administrators as data scientists mining information, tracking individual student and teacher performance and making subsequent changes based on the data. Unfortunately, so much of the hype for using Big Data ignores time, place, and people.
Context matters.
Consider what occurred when Nick Bilton, a New York University journalist and adjunct professor designed a project for his graduate students in a course called “Telling Stories with Data, Sensors, and Humans.” Could sensors, Bilton and students asked, be reporters, collect information, and tell what happened?
The students built small electronic machines with sensors that could detect motion, light, and sound. They then asked the straightforward question whether students in the high-rise classroom building used the elevators more than the stairs and whether they shifted from one to the other during the day. They set the device in some elevators and stairwells. Instead of a human counting students, a machine did.
