This Will Revolutionize Education
Derek Alexander Muller,
According to this video, "what limits learning is what happens inside a student's head... no technology is inherently superior to any other." So, says the video, "the question really is, what experiences promote the kind of thinking that is required for learning?" We've learned some good lessons here and have probably come close to optimizing the presentation of information. So why do we need teachers? Because, argues the video, the purpose of teachers is not to present information, but rather, to guide the process of learning, "to inspire, to excite, to challenge their students." Indeed, "making a learner think seems best achieved inside a social environment." So, let me ask - can we do this without a teacher? Via Ronnie Burt.
