Abstract |
In Traditional Classroom, Thai students individually do their seat works. The traditional teaching was sequences as: reviewing the previous lesson, explaining new contents by teacher, exampling by teacher, and exercising by students individually. Students have not opportunity to discuss and share mathematical ideas naturally.
This study is a part of the 3-years Research Project on “Model for Fostering Students’ Mathematical Thinking by Implementing Lesson Study and Open Approach” by Center for Research in Mathematics Education (CRME) of Khon Kaen University which introduces Open Approach as a teaching approach in urban school of Khon Kaen. The sequences of teaching approach as: posing the open-ended problem, small-group working, whole class discussion, and summarizing the lesson. The small-group working is the session which students communicated mathematical ideas naturally. Open Approach provides students with opportunity to engage in small-group mathematical communication (SMC) in which defined as communication in small-group working including characteristics of mathematical communication according to Emori (2005). SMC is treated as social interaction, according to Steffe & Thomson (2000) noted that learning occurs in particular interactions in which students modify their current schema. According to Rumelhart (1984 cited in Byrnes, 2001), schema was modified by one of three processes: accretion, tuning or restructuring.
This study was conducted during the 2007-2008 academic years by the purpose of analyzing schema change in SMC. To accomplish the purpose, targeted group were selected from the 7th grade students by using ethnographic method. Collaborative lesson planning, classroom observation, clinical interview and reflection on the lessons were done. Protocols of SMC were analyzed.
Conclusions point out that students have richly opportunity in learning mathematics by changing their current schema in SMC through Open Approach.
