算数・数学教育における教師の専門性に関する研究

抄録

The first aim of this study is to explor the professionalism of teachers in mathematics teaching and, based on it, to refer the ideal mathematics teachers. And the second one is to make some proposals on preservice and inservice teacher education programs. To explor the professionalism of teachers in mathematics teaching, I considered both social and individual aspect of mathematics teachers. In sosial aspect, I searched some studies and I considered six characteristics of teaching profession. The professionalism of teaching profession is that teachers perform their duty through being conscious of these six characteristics. In individual aspect, I assumed that the individual professionalism of teachers would appear in style of thinking and performing. And I compared expert teachers with novice teachers by searching some referentional studies so that I could extract the individual professionalism of teachers through drawing out the characteristics of expert teachers. Experts are proficient in complex cognitive skill and improvisational performance. They are sperior in reading a classroom and making decision than novices. The ability on reading a classroom and making decision is based on their knowledge that is relevant to subject matter, pupil and student, and teaching and management. Experts are excellent in all these respects. Hence the ability on reading a classroom and making decision is a significant component of the individual professionalism of teachers in mathematics teaching. The individual professionalism of teachers in mathematics teaching is proportion to a wealth of expertise. Therefore it is very important to pursue knowledge and to improve teacher's ability on reading a classroom and making decision in preservice and inservice teacher education programs, because a teacher who has a wealth of expertise and who is sperior in reading a classroom and making decision is one of the ideal mathematics teachers. And a teacher who is autonomous is also one of the ideal mathematics teachers. To be autonomous is important for professional development. Summarizing them, I maked some proposals on preservice and inservice teacher education programs.
