初中数学教师除了应具备数学专业知识、教育基本理论外,还应该具有与数学学科、日常生活密切相关的其他方面的知识,既有数学专长,又广泛涉猎其他知识领域,其中包括社会科学、自然科学、社会生活常识及新兴学科等。
总之,教师在这些知识结构中,对于与学生的学习、生活以及参加各项社会实践活动有关的方方面面的知识与信息,都要有所涉略。有条件的教师,还应该使用多媒体技术,使计算机成为课堂教学的辅助工具,推进教学手段的现代化。这既可以扩大教师自身的知识面,增强教育、教学的效果,唤起学生强烈的求知欲,又有利于建立起教师在知识方面的权威性,赢得学生的尊敬、爱戴与信赖,使教师成为学生探求知识与追求真理的楷模。

教育科研是一种运用科学的方法和手段,有目的、有计划地探索、发现、掌握教育、教学规律的认识活动,是一个立足于已知去探求未知的过程。为了能正确地开展教育科研活动,教师必须具备相关的基础知识,如教育科学研究的选题如何确定,如何选择研究与论证的方法和手段,研究结果的定性与定量分析等。教师要着重学习教育研究方法、教育统计方法、教育测量、教育评价等有关进行教育科研的基础知识。
我初次担任初中的数学教学工作,在教学中曾遇到过很多困惑。为了使自己能更好地胜任这份工作,我选择了阅读《初中数学教学策略》这本书。
所谓的教学策略,是指为完成一个特定的教学任务,对相关教学任务的教学目标、教学内容、教学方式、组织形式、教学资源等做出的系统设计及采取的具体措施。对于一名数学教师来说,采用什么样的教学策略才能有效地从事初中阶段的数学教学,提高数学教学效果?书中说到:教师在制定一个明确的教学策略的时候必须在教学内容和学生状况两大方面上进行观察、思考与分析。在教学内容分析中主要谈了一下教学目标。作为教师的我们都知道教学目标是指“为什么而教”、“学生学完这些内容后能够做什么”。教学目标有远期目标和近期目标之分。
远期目标可以是某一课程内容学习结束时所要达到的目标,也可以是某一学习阶段结束后所要达到的目标。结合初中数学教学内容,我觉得远期目标应包括:
一、让学生自己探索基本的数量关系、图形性质,在探索中发展他们的推理能力。
二、把生活中的实例带入课堂,使问题生活化,从而使学生体会到学习的必要性。
三、让学生从几个基本事实出发,证明一些有关三角形、四边形等的基本性质,进而掌握综合法证明的基本格式。
在日常教学中,学生数学推理能力的培养是很重要的,它是我们教学上的一个远期教学目标,它不可能在一天、几天、几个月内就完成的,我们每一节课都要对学生进行一些培养数学推理能力的练习,我们在设计教学策略的时候就需要把这一方面考虑进去,采取适当的教学策略以培养学生的数学推理能力。
《初中数学教学策略》一书,让我对初中数学教学有一个清晰的认识,领悟了初中数学教育教学工作的真谛,掌握了初中数学教学基本策略,从而提高了从事初中数学教学工作的基本能力。让我觉得作为一名合格的教师,要不断提高初中数学教师的科学文化素养。只具备良好的职业道德素质,有一个全心全意做好工作的愿望是远远不够的。
向学生传授文化科学知识应该是教师的一项基本任务。教师的文化科学知识素养决定着教师对教学内容把握的准确度,决定着教师教学能力与教学质量的高低,也直接关系着学生知识结构的形成、智力的发展与能力的培养。现代数学教师的科学文化知识包括以下几个方面:
