Brown's class was discussing some of the whaling calculations in Moby Dick. When one student asked a question involving a complex computation, three students quickly pulled out their cell phones and did the math. Brown was surprised to learn that most cell phones have a built-in calculator. She was even more surprised at how literate her students were with the many functions included in their phones. She took a quick poll and found that all her students either had a cell phone or easy access to one. In fact, students became genuinely engaged in a class discussion about phone features. This got Brown thinking about how she might incorporate this technology into learning activities.

Brown noticed that many students used text messaging to communicate, and considered how she might use cell phones in summarizing and analyzing text to help her students better understand Richard III. Effective summarizing is one of the most powerful skills students can cultivate. It provides students with tools for identifying the most important aspects of what they are learning, especially when teachers use a frame of reference (Marzano, Pickering, & Pollock, 2001). Summarizing helps students identify critical information. Research shows gains in reading comprehension when students learn how to incorporate isummary framesi (series of questions designed to highlight critical passages) as a tool for summarizing (Meyer & Freedle, 1984). When students use this strategy, they are better able to understand what they are reading, identify key information, and provide a summary that helps them retain the information (Armbruster, Anderson, & Ostertag, 1987).

Text messaging is a real-world example of summarizing—to communicate information in a few words the user must identify key ideas. Brown saw that she could use a technique students had already mastered, within the context of literature study.

The phenomenon is beginning to worry physicians and psychologists, who say it is leading to anxiety, distraction in school, falling grades, repetitive stress injury and sleep deprivation.

Psychologists expect to see teenagers break free from their parents as they grow into autonomous adults, Professor Turkle went on, “but if technology makes something like staying in touch very, very easy, that’s harder to do; now you have adolescents who are texting their mothers 15 times a day, asking things like, ‘Should I get the red shoes or the blue shoes?’ ”
