新课标初二数学教学计划
新课标
一
5，6班学生思维活，但两极分化严重，在要提高生成，要指导部分后进生的学习兴趣，在知识上应该顾两方面的学生，给教学加大了难度，另一方面，要做好后进生的
二 指导思想：
以《初中数学新课程标准》为依据，面推进素质教育。数学是人们生活、劳动和学习必不可少工具, 能够帮助人们处理数、进行计算、推理 明，数学模型可以有效地描述自然象和社会现；数学为其他科学提供了语言、想和法，是一切重大技术展的础；数在提高人推力、抽象能力、想像力和创造力等方面有着独特的作用；数学是人类的一种文化，它的内容、、方法和言是现代文明重组成部分。学生的数学学习内容当现实的、有意义的、富有挑战性的，这些内容要有利 于学主动地进行观察、实验、猜测、验证、推理与交流等数学活动。内容的呈现应采用不同的表达方式，以满足样化学习需求。有效的数学学习活动不能单地依赖模仿与记忆动手实践、自主探索与合作交流是学生学习数学的重方式。由学生所处的文环境、家庭和自身思式的不同，学生的数学学习活动应当是一个活
三
1、分式的重是分

五 教学措施：
1、加强教学
面向全体学生。由于生在知识、技能方面的发展和趣、特长等不尽相同，所以要因材施教。在组织学时，从大多数学生的际发，并兼顾学有难和有余力的学生。对学习有困难的学生，要特别予以心，及时采取有措施，激发他们学习数学的兴趣，指导他们改进学习法。帮助他们解决学习中的困难，使他们经过努力，能够到大纲中规定的基本要，对学有余力的学生，要通过讲授选学内容和组织课外活动等种形式，满足他们的学习愿望，展
2、注重方法
重视改进教学方法，持启发式，反对注入式。教师课前先布置学生预习，同时要指导学生预习，提预习要，并布置与课本容关、难度适中尝题材生课前完成，教学中教师应帮助学生梳理新课知识，出重点和易错，解答学生预习时遇到的问题，再设计提高题由学生进尝试，使学生在学习中体会成功，调动学习积极性，同时可激励学生自我编题。力培养学生发现、得出、分析、解决问题的能力，包括将实际题上升为数学模型的能力，注励
3、改革作业结减轻学生负。将学按能力分成几个层次，分别布置难、
