前不久,我市教科院组织了市直高中青年数学教师的课堂教学竞赛活动,课题是“求函数零点近似解的一种计算方法——二分法”(人教A版《数学1》(必修)第2.4.2节)。共有8位青年数学教师参加了赛课活动,每节课都有可圈可点之处,但是从课堂的呈现和授课教师的自评来看,也存在着不少问题。1课堂中暴露的问题教师在课堂中暴露的问题,主要源于对新课程理念的理解不够深刻与学科素养的欠缺。具体主要体现在以下几个方面:1.1忽视教材,信息技术的泛滥使用
Not long ago, the city of Academy of Sciences organized a straight school high school young mathematics teachers classroom teaching competition, the subject is “seeking a function zero approximate solution of a calculation method - dichotomy” (People teach A version of “Mathematics 1” ( Required) Section 2.4.2). A total of eight young math teachers participated in the competition activities, each lesson has remarkable, but from the classroom presentation and instructor self-assessment point of view, there are still many problems. Problems Exposed in Classroom The problems teachers exposed in the classroom mainly stem from the lack of deep understanding of the concepts of the new curriculum and the lack of academic literacy. Specific mainly in the following areas: 1.1 ignore teaching materials, the proliferation of information technology
