"So I'd like to get more specific about what I think is wrong about the Khan Academy approach by writing about things I see as wrong with the way we teach math in the US. No matter if we agree or not about Khan Academy, I'm fairly certain we can agree math learning is not going as well as we'd like (to say the least.) Too many people are convinced by the system that they "hate math", and even students who do well (meaning, can get decent test scores) are often just regurgitating stuff for the test, knowing they can safely forget it shortly afterward."

"It is a common view that "if only someone could break this down and explain it clearly enough, more students would understand." Khan Academy is a great example of this approach with its clear, concise videos on science. However it is debatable whether they really work. Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven't learned anything. The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge. There is hope, however. Presenting students' common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it."

"This Friday's Reporters' Roundtable is on a topic that vexes us all: why are end user license agreements and terms of service so long and convoluted? To get ourselves in the mood for this show, we asked CNET fan (and Academy Award winner) Richard Dreyfuss if he'd help us out by doing a dramatic reading of the Apple EULA. He said yes. So, without further ado, we present to you,"
