Abstract
The objectives of this research were to explore the characteristics of mathematical representations of students in classroom through the lesson study and open approach of multiplication using a qualitative research model. The target group is Prathom Suksa 2, Semester 2, Academic Year 2019, Ban Mae Sa School, total 30 people, the research tool is 10 lesson plans on multiplication (3). Still camera video recorders and observation record form the data to be analyzed is data in still images. Student work or activity sheet and the protocol obtained by transcribing the text from the video. Data were analyzed using protocol analysis and Cramer & Karnowski’s mathematical representation framework.
The research results were found that students have mathematical representations of multiplication as follows: 1) picture mathematical representation to represent numbers. Students use drawing, such as blogging, things in their daily life based on the student experience. To represent the number of members in each group. 2) Mathematical representation with pictures to represent multiplication. Students draw pictures instead of multiplication by drawing circles around the picture. Drawing objects attached together in groups to represent groups.
