我们备课组在学习教学大纲,钻研数学教材的过程中,深刻体会到:要使学生从初一起就能适应教材要求,有效地防止和克服学生知识和能力的分化,一方面要作好小学到初一知识和能力的过渡,另一方面又要为学生进一步学习打好基础。一年来,我们在教学实践中,坚持按照大纲和教材的要求,落实双基,培养能力,通过旧知向新知的转化,培养探索能力和数学思维方法,有意识地、有计划地着重抓了以下几个问题。一、特殊数的概念及应用1.数“0”的概念及应用。在小学算术里,数0表示没有的意思。初一讲了有理数后,0除了表示没有以外,还有许多独特的实际意义。例如:
Our lesson preparation group in learning the syllabus, study mathematics textbooks process, deeply realized: to enable students from the very beginning to adapt to the requirements of teaching materials, effectively prevent and overcome the differentiation of students knowledge and ability, on the one hand to make primary school to First, the transition of knowledge and ability, on the other hand, we must lay the foundation for students to further study. In the past year, we insisted in accordance with the requirements of the outline and teaching materials, implemented the double bases and cultivated our capabilities in the teaching practice. Through the transformation from old knowledge to new knowledge, we have cultivated the ability of exploration and mathematical thinking, consciously and systematically focused on the following A question. First, the concept and application of special number 1. Number “0” concept and application. In elementary arithmetic, the number 0 means no meaning. After talking about rational numbers in the first day, there are many unique and practical meanings aside from that. E.g:
