On the peer-to-peer instruction in high school mathematics education, a case study

The purpose of this note is to report on an educational experiment conducted in the academic year 2020/21 in a Polish high school under the pandemic situation. We discuss some various scenarios of implementation of the peer instruction method as developed by Eric Mazur blended with the flipped class approach. The material used during the experiment is discussed in grade 11 and concerns polynomials and their properties. The experiment was conducted in two classes. We were primarily interested in using peer instruction to eliminate errors in students' reasoning resulting from deep misconceptions.
