数学能力是教师数学专业素养的重要组成部分。通过对中学数学教师应具备能力的重要性程度与现状水平的调查,发现教师对具备数学能力的重要性有清楚的认识,而目前中学教师能力的现状还不能让人满意,尚有不足之处。然后从“能力获取”的视角,将教师能力发展划分为体验、交流、解读、反思等四种途径,并讨论了每种方法的实施策略。 Mathematical competence is an important part of teachers’ mathematical professional accomplishment. Through the investigation of the importance and ability of middle school mathematics teachers, we find that teachers have a clear understanding of the importance of having mathematics ability. However, the current situation of middle school teachers’ ability is still unsatisfactory and there are still some shortcomings . Then from the perspective of “ability acquisition ”, the author divided the development of teachers’ abilities into four ways of experience, communication, interpretation and reflection, and discussed the implementation strategies of each method.
