You might say Osmosis and SketchyMedical share some DNA. Both learning platforms were started by medical students seeking a better way to manage the avalanche of information they had to memorize; both companies use animated videos with an approachable style; and both root their content in learning science. Sketchy’s key approach borrows from a method developed by the ancient Greeks that relies on visual-spatial memory to acquire and retain knowledge. They also keep fun front and center. “That fun aspect is harder to be objective about and to judge,” says co-founder Andrew Berg, “but we found that the more fun we're having when we're creating content, that translates into more fun the students are having and very likely makes it more effective as a learning tool.” Check out this fascinating (and fun!) discussion about the power of visual lessons to increase speed of learning and retention, the myth of learning preferences, and plans to apply the approach to non-medical subject areas.
