在我的课堂中,氛围融洽、民主,学生学习的积极性高,兴趣浓厚,对此,我颇有点儿自得。直到有一次市数学教研员来我校指导工作,听我上了一节课题为“十几减9”的课。自那节课后,我开始冷静下来,客观地反思自己的课堂教学。“十几减9”是小学一年级退位减法的起始课,教学的重、难点在于学习“十几减9”的计算方法。《数学新课程标准》中指出:“由于学生生活背景和思考角度不同,所使用的方法必然是多种的,教师 In my class, I am quite content with my enthusiasm and interest in a harmonious atmosphere, democracy and student learning. Until there is a city of mathematics teaching and research staff to guide our work, listen to me on a subject for ”more than minus 9 “ class. After that lesson, I started to calm down and objectively reflect on my class teaching. ”Less than 10 minus 9 “ is the first class of absenteeism and subtraction in primary school, the teaching of the heavy, the difficulty is to learn ”more than a dozen minus 9 “ calculation method. ”New Mathematics Standard“ states: ”Due to the different student life background and thinking, the method used must be a variety of, teachers
