整体这个概念含义广泛,界线难以划分.比如,按系统论的观点,整个小学数学知识是一个系统的整体,而某个年级、某一单元、某一节的数学知识,又可分别看作这个系统的子系统,也可看作一个整体.若把小学数学各种教学方法看成一个整体,其中每一种方法也可看作一个整体.一节数学课,从开始到结束,整个教学过程可看作一个系统的整体,如果这个整体是个优化组合的整体,便能取得最佳教学效果,否则相反.研究、探讨小学数学教学优化组合的整体模式,是深化小学数学教学改革,提高教学质量的杠杆.
For example, according to the theory of system, the whole elementary school mathematics knowledge is a systematic whole, and the mathematics knowledge of a certain grade, a certain unit and a certain section can be regarded separately as this System subsystem can also be seen as a whole.If the primary school mathematics teaching methods as a whole, each of these methods can also be seen as a whole.A mathematics lesson, from start to finish, the entire teaching process Can be regarded as a whole system, if this whole is a combination of optimization, the best teaching effect can be obtained, otherwise, the overall mode of researching and exploring the optimal combination of primary mathematics teaching is to deepen the reform of primary mathematics teaching and improve the quality of teaching Leverage.
