Exploration of teachers' 'knowledge of students' in studybased teaching on polyhedron material

摘要

Teachers' knowledge in "knowing" student problems is an important factor to support the improvement of the Mathematics learning process in the classroom. Therefore, this research aims to explore the teacher's strategies to overcome students' errors/misconceptions in the material of polyhedron. This is an explorative study and carried out with a qualitative approach so that it contains a set of credible facts that were revealed in depth. Some instrument that used are; field notes, observation sheets for teacher activities, student activities, and learning transcripts A phase lesson study scheme was also applied to create coherent learning scenarios. This combination resulted in findings that had an impact on improving teacher skills in dealing with the errors made by students in terms of concept, procedure, and initial knowledge systematically. The findings of this study were; the teacher can describe the types of knowledge about students' errors/miskonceptions, and then developed strategies to deal with errors/misconceptions effectively.
