Video Version available at DecodingLearningDifferences.com   I recently was confronted (on this podcast episode!) with a myth that I had spread widely believing to be true: that learners retain 90% of what they teach.  I had never believed that the pyramid this fact was based off of was exact or precise but rather a generalization of lots of research.  It also was supported by the real-life experiences I had.   And yet– I had trusted the sources that first told me about this pyramid.  That led me to spread it to others and so on, and if any of us had looked into deeply, we would have seen it’s just a common myth that has spread WIDELY!   So, do educators lie? Sometimes.  And sometimes educators fall for misinformation just like everyone else.  So what do we do about it?  Check the facts!  And set the record straight when you can!
