Developing a Research Lesson for Preservice Teachers: Lesson Study in Higher Education


Often pre-service elementary teachers become pre-occupied with remembering/mastering procedures for performing operations with fractions. They lose sight of the importance of understanding the unique value or amount represented by a fraction in a variety of situations. Our goal was to create a research lesson that assists in developing an understanding of the concept of a fraction and awareness of and connections between multiple representations of fractions. Data collected through our first cycle of Lesson Study (plan, teach, debrief, revise) informed the revisions that led to greater emphasis on the development by students of a working definition of a fraction.
