"The Problem
During lectures, it's hard for every student to let you know if they understand or if they're confused. Especially in large classes, many students are reluctant to express their confusion which limits both their learning and their enjoyment.
The Solution
Understoodit addresses this issue by allowing students to anonymously, and in real-time, indicate if they understand or are confused. Understoodit runs on devices that you and your students already own: smartphones, tablets, netbooks and notebooks."
"Professors who wish to engage students during large lectures face an uphill battle. Not only is it a logistical impossibility for 200+ students to actively participate in a 90 minute lecture, but the downward sloping cone-shape of a lecture hall induces a one-to-many conversation. This problem is compounded by the recent budget cuts that have squeezed ever more students into each room.
Fortunately, educators (including myself) have found that Twitter is an effective way to broaden participation in lecture. Additionally, the ubiquity of laptops and smartphones have made the integration of Twitter a virtually bureaucracy-free endeavor. This post describes the two main benefits professors find when using Twitter in lecture."
I do think that the author's conclusion about it being a great way to deal with growing class sizes due to budget cuts is simplistic and misses the point about it being a great way to engage students, period.
