This paper by Bryan C. Hassel explores two cutting-edge trends that have revolutionized organizations in other sectors: mining the mountain of data generated by the daily activities of employees and customers, and tapping the “wisdom of crowds.” Appearing in the Thomas B. Fordham Institute’s volume A Byte at the Apple: Rethinking Education Data for the Post-NCLB Era, the chapter highlights the experience of organizations ranging from Amazon.com and Google to Wal-Mart, Capital One, and the NYC Police Department to describe how these techniques have made quantum leaps possible in other sectors. Potential education applications include learning from the “clicktrails” that students leave behind as they engage in software-based activities; inexpensive randomization of instructional techniques to spur more rapid learning about “what works”; and tapping the wisdom of teachers nationwide to enable the best lesson plans to rise to the top.
