增强教学有效性,这是我们一直以来追求的目标。近年来,上海“绿色指标”紧紧围绕新型的教育模式和理念,不只关注学业成绩,更强关注教师的因材施教、学生的自我探究的能力。有效的数学学习来自学生对数学活动的参与,而参与的程度在于教师的引导。因此,在数学课堂中教师如何转变教学理念,引导学生主动参与探究,并及时给予学生准确、正面的评价,是我们需要认真研究的课题。 Enhance the effectiveness of teaching, which is the goal we have been pursuing. In recent years, Shanghai “green indicator” closely focuses on the new education model and philosophy. It not only pays attention to academic achievements but also pays more attention to teachers ’aptitude for self-exploration and students’ self-exploration. Effective mathematical learning comes from students’ participation in math activities, and the degree of participation is guided by the teacher. Therefore, in the math classroom teachers how to change teaching philosophy, guide students to take the initiative to participate in inquiry, and timely and accurate assessment of students, is that we need to seriously study.
