The expert blind spot hypothesis provides an explanation as to why experts with superior content knowledge find it difficult to communicate this knowledge to novices. Previous studies have shown that as predicted by the expert blind spot hypothesis, participants with more advanced mathematics education are more likely to believe in the necessity of symbolic reasoning and mastery of equations as a prerequisite for algorithmic or mathematical problem solving. This pattern has been shown across several subject areas including mathematics, science, and language arts. While there has been a good deal of work done identifying this issue, findings have been slow to transfer to teachers in the field. This project integrates findings regarding the expert blind spot into an online training module that will educate in-service teachers about the expert blind spot and provide strategies to overcome its pitfalls. / text
