AN ETHICAL QUESTION: Larry Cuban is a skeptic when it comes to education technology living up to all its promises. But he believes that trying untested technologies in classroom is not unethical, as one education professor has suggested. Cuban argues in his blog that unproven does not equal unethical. For even though many tools are often unpolished and used as betas, "I think of the many instructional practices that have been used for centuries, such as textbooks, worksheets, blackboards, and homework that underwent no tests then or now," he writes. One commenter adds: "To suggest that new technology should not be provided to teachers and students until it has been rigorously tested seems misguided."
