新课程的改革提出以学生为主体,教师在整个教学中起引导作用。同时,要积极培养学生的创新意识、合作探究等能力,以促进学生个性和谐地发展。在数学课堂中,尤其是在小学低段的数学课堂中,要实现这些目标,就要做到“讲”“练”结合。即集“看中思,思中学,学中练”为一体。 The reform of the new curriculum proposes to take students as the main body, and teachers play a guiding role in the whole teaching. At the same time, we should actively cultivate students’ innovative awareness, cooperative exploration and other capabilities to promote the harmonious development of student personality. In mathematics classrooms, especially in the math classroom of the lower elementary school, to achieve these goals, we must achieve “lecture ” “training ” combination. That set “fancy thinking, thinking middle school, learning practice ” as a whole.
