最近,在武汉市二中举行了一次高二数学研究课。课题是解析几何中的点到直线距离公式。来自华师一附中、二中、新世纪学校的数十名教师参加了这一活动。执教的张家龙老师根据二中“思维与数学教学”课题组的目标要求——让思维真正进课堂,尽力让学生思维充分展开,探讨数学课堂教学中提高其素质教育功能的途径,课前作了认真的思考与用心 Recently, a high school mathematics research class was held in Wuhan Second Middle School. The subject is analytic geometry in the point-to-line distance formula. Dozens of teachers from Secondary 1, Secondary 2, and New Century schools attended this activity. According to the target of “thinking and mathematics teaching” in the second group, Zhang Jialong, the instructor, aims to make the thinking really enter the classroom, make every effort to let the students think fully, explore the ways to improve the quality education in mathematics classroom teaching, Thinking and intentions
