节奏,是一个音乐术语,它与旋律一样,同是构成音乐的基本要素。 数学课堂教学也要有节奏。教育心理学告诉我们:学生在听课过程中,其大脑优势兴奋中心是随时间的一维演进呈曲线变化的,且这种兴奋中心不是长时间固定在大脑皮层的一定区域,而是随着刺激物的变化而不断转移的。因此,从一节课的开始到结束,不能总是平铺直叙、无峰无谷,也不能总是一个音节、一种速度,必须紧扣学生思维的兴奋中心,精心设计教学节奏,做到有张有驰、有展有敛、动静交替、疏密有 Rhythm is a musical term, which, like a melody, is a basic element of music. Math class teaching also has a rhythm. Educational psychology tells us: students in the process of leaning, the brain center of excitement is a one-dimensional evolution of the curve over time, and this excitement center is not fixed in a certain area of ​​the cerebral cortex for a long time, but with the stimulation Things change and continue to shift. Therefore, from the beginning to the end of a class can not always be straightforward, no peaks and valleys, can not always be a syllable, a speed, must be closely linked with the student's excitement center of thought, well-designed teaching pace, so there Chang Chi , There is convergence of convergence, static and dynamic alternation, density there
