Sundanese ethnomathematics in fractional number learning with engklek games in pre service students: Didactical design findings

The purpose of this study was to test Sundanese ethnomathematical learning with the engklek game to improve the creative thinking skills of elementary school teacher education students by using teaching materials compiled with the Didactic Design Research method. This study tries to compile different cultural and educational backgrounds of students to get the right teaching materials. Research subjects used 78 students in the learning obstacle stage, 26 students in the initial didactic design stage, and 42 students in the revised didactic design. The data were obtained with the learning obstacle test instrument, the initial didactic design, and the revised didactic design. This study found that different cultural and educational backgrounds face the same difficulties in creative mathematical originality and flexibility in modeling images in the representation of fractional number ideas. The initial didactic design was followed by a revision of the didactic design in Sundanese ethnomathematical learning with the Engklek game by successfully reducing learning barriers. Sundanese ethnomathematics learning with the engklek game can improve students' mathematical creative thinking skills in learning mathematics
