Abstract

The research objective was to study the 4th-grade students’ fraction schemes in classrooms that manage to learn by the Open Approach. A qualitative method, participatory observation, and teaching experiments were used. The target group was 26 people in the 4th grade of Wat Kajornrangsan Municipal School, Phuket province this school used Lesson Study and Open Approach innovation since 2020. The research tools including the 5 lesson plans, IC recorders, camera, video recorder, and field notes, were research tools. Data were collected in the second semester of the 2022 academic year by recorded video, IC record, and field notes. Data were analyzed by using the protocol and descriptive analysis following the theoretical framework of Steffe & Olvie (2010)


The result revealed that the students had fractional operations into 5 types as follows 1) Students the units and whole by folding the paper and pouring water 2) Students separated the unit and whole into equal parts by folding the paper 3) Students imagined the whole and explained the quantity by pouring water 4) students noticed the relationship between the unit of fraction and the whole, and 5) students explained the size of the fraction on both decomposing and composing of a fraction.
