课程改革背景下,如何让新理念走进课堂,如何让新理念渗透于教学,从而有效地进行数学教学,是每位数学教师必须面对的问题。为此,伴随新课程实施,我们一直在努力,努力寻找适合学生、适合自己的课堂教学;我们一直在思索,思索怎样的“教”最有价值;我们一直在期待,期待能引领学生走进真、善、美的知识世界。一路上,磕磕绊绊,但前面的风景依旧独好;一路上,辗转反侧,但仍在契而不舍地追寻。试图在有效教学理念指引下,从准确把握教材、注重学生自主探究的有效环节、追寻真实本色的生态数学等层面重构有效教学,从而让有效充盈小学数学课堂,以实现小学数 Under the background of curriculum reform, how to let the new idea into the classroom, how to infiltrate the new idea in the teaching, so that to carry on the mathematics teaching effectively is the problem that every mathematics teacher must face. To this end, with the implementation of the new curriculum, we have been working hard to find suitable for students, suitable for their own classroom teaching; we have been pondered, thinking what kind of “teaching” the most valuable; we have been looking forward to looking forward to lead the students Into the true, good and beautiful knowledge of the world. Along the way, stumbling, but the front of the landscape is still unique; Along the way, tossing and turning, but still reluctantly pursuing. Under the guidance of effective teaching philosophy, the author attempts to reconstruct effective teaching from the aspects of accurately grasping the teaching materials, paying attention to the effective links of students’ autonomous inquiry, and pursuing the true character of ecological mathematics, so as to effectively fill the math classroom in primary schools
