As a Technical Support Specialist, Browserlock and faculty concerned about "cheating" fail to comprehend the world in which we live. The old thinking of memorizing answers or being able to recall answers based on reading and cramming in lots of data is an outdated method.
A Doctor doesn't in go into surgery remembering every iota of their medical books. A lawyer is not required to know every law on the books. A rocket scientist doesn't attempt jet propulsion based on remembering every theory and law from years of study. Every profession has the answer to the tests! There is no "stump the chump" in any profession. The answers are available for immediate use. What separates the average from the greats is the ability to not only find answers but apply it in ways that are new or unprecedented.
Why should a kid memorize the multiplication table? We have phones that can calculate that and it is much more reliable than memory. Why must a student be forced to memorize when a certain battle took place in history or remember such minutiae when it is recorded history? This basic level of assessment speaks to issues with the instrument, not the student!
With information at a student's fingertips, the next level of learning should be for students to analyze and synthesize the information. Baseline teaching and assessment is the expectation of knowing that Columbus sailed the ocean blue in 1492 whereas the synthesis and analysis can apply that voyage to World Systems Theory and disproving of the Malthusan Trap. This will create a world where there isn't really a "right answer" but, rather shows metacognition while also creating new insights on very old (probably incorrect) subjects.
Handheld devices also empower a student to learn on their own terms outside of a rigid outdated system. What is the folly in that? Students, as living breathing organisms, will naturally have questions about the environment about them and be able to find answers in the palm of their hand.
Educators should embrace all technologies in the classroom if they spur questions and ideas in the classroom.
