Vail, Arizona, high school ditches books, wires: The high school of 350 students will use laptops and electronic texts. The methodology of whether this works is based on the superintendent looking around at other schools, but apparently not viewing results like attendance, test results, and softer measures. Further, the article doesn't touch on the problem with electronic texts, that they're highly controlled for distribution and licensing and often have limited periods of use, such as a year or a school year. Conventional textbooks can last several years, be handed around, and even used by (gasp) more than one person at a time.
Until such a point that electronic textbooks have the same flexibility and usefulness--not just up-to-date-ness, when that's even happening--as print textbooks, the value of this switch is not documented, not supported by research, and not wise.
