High-tech gadget transforming college teaching - and learning

The Philadelphia Inquirer reports:

Freshman Sarah Speicher stared down at her syllabus in the bookstore at Temple University, considering her next purchase. "Clicker?" she asked out loud. "What's a clicker?"

A clicker, she soon discovered, is a "personal response device," a small electronic gadget the size of a slim calculator that she and her 399 classmates in Law and American Society would be toting to class.

The trendy, high-tech learning tool, used to take attendance, poll student opinion, and administer quizzes, is taking hold on campuses across the country, with an estimated two million college students now using them, transforming teaching - and learning.
