近年来,小学数学课堂教学改革尽管取得了一定的进展,但普遍存在的诸多弊端仍程度不同地制约着素质教育的真正推进,传统观念根深蒂固并仍然束缚着教师的行为,使本应积极、主动、生动、谐趣、乐道的小学数学教学仍显深沉、严肃、呆板,使学生丧失了学习数学的兴趣。因而,构建充满生机的小学数学课堂教学机制便成为小学数学教学改革的一个热点。 In recent years, although some progress has been made in the reform of primary school mathematics classroom teaching, the many common defects still restrict the real advance of quality education. The traditional concepts are still deeply entrenched and still constrain the teachers’ behaviors, so that they should be active and active Vivid, fun-filled, happy primary school mathematics teaching is still deep, serious and rigid, so that students lose their interest in learning mathematics. Therefore, to build a vibrant primary school mathematics classroom teaching mechanism has become a hot topic in elementary mathematics teaching reform.
