Lesson study as a research approach: a case study

Abstract

Purpose: The purpose of this paper is to explore the merits of lesson study (LS) as a research approach for research in (science) education. A lesson was developed to introduce students to model-based reasoning: a higher order thinking skill that is seen as one of the major reasoning strategies in science. Design/methodology/approach: Participants of the LS team were three secondary school teachers and two educational researchers. Additionally, one participant fulfilled both roles. Both qualitative and quantitative data were used to investigate the effect of the developed lesson on students and to formulate focal points for using the LS as a research approach. Findings: The developed lesson successfully familiarized students with model-based reasoning. Three main focal points were formulated for using LS as a research approach: (1) make sure that the teachers support the research question that the researchers bring into the LS cycle, (2) take into account that the lesson is supposed to answer a research question that might cause extra stress for the teachers in an LS team and (3) state the role of both researchers and teachers in an LS team clearly at the beginning of the LS cycle. Originality/value: This study aims to investigate whether LS can be used as a research approach by the educational research community.
