We’ve written before on how organizations like Virtual Nerds or individuals like Salman Khan are capitalizing on easy access to video and then harnessing the Internets capability to rapidly disseminate short chunks of information through multiple channels. The ability to access specific, targeted material – and repeatedly view on-demand content – means that many students are able to engage with the content in a setting of their choice, a setting hopefully free of other distractions. Plus, accessing information on-demand means that students are able to free up valuable mental real estate; students don’t have to be distracted by monitoring social cues or focusing on facial expressions, or even worrying about the speaker’s perception. Instead, the student is free to focus almost exclusively on the actual content.
Here’s Khan at a recent TED talk explaining what he thinks may account for the appeal of his math videos.
Khan is not alone. Vi Hart has garnered recent acclaim for her ability to take high-level, abstract, mathematical concepts and render them both accessible and fun. Hart offers her visual work and explanations through both YouTube and her own site.
Video formats – like the Khan Academy YouTube videos and those created by Virtual Nerds – offer math students a valuable way to reinforce their current lesson or access more in-depth explanations in a setting of their choice. That sort of accessibility and ease of use were a part of our thinking in making both Virtual Nerds and Khan Academy videos available through our own Math at Home utility. Math at Home allows parents and educators to link students to resources at a targeted level based on the Quantile Framework for Mathematics.
