作为一一名任课教师,我们或许都有过这样的体验,每当上完一节好课,会让你有意犹未尽之感,全身都会感到舒爽之至。而往往公开课更容易达到这样的境界。想想为什么,一个很重要的原因就是我们无形中做到了“懂”、“透”、“化”。 总之,我们在处理教材上真正做到“懂”、“透”、“化”,真正做到“钻进去,走出来”,就会达到创设教材研究的理想境界。
一、全体教师必须服从上级和学校的管理,自觉做到依规办事、依法治教,遵守上级和学校的各项规章制度,做到遵纪守法、教书育人、为人师表,崇尚科学,反对邪教。 二、学校内部教师人事调整,由学校领导班子成员根据教师的专长和表现,召开专门会议研究讨论决定,人事调配实行一次性讨论,一经讨论确定,原则上不得变动,特殊情况需要调整的要经过学校领导班子集体讨论决定。 三、每学期对教师的各方面表现进行一次业绩考评,考评结果由高分到低分排队,末位的实行待岗;考评结果作为教师评聘、评优、评先、考核、晋升的重要依据。 四、实行教师聘任制,学校根据教师的平时的表现和业绩考评结果,由校领导班子根据学校和岗位的需要,确定聘任教师的名单,各教师与学校签定聘任协议。

本人所教的两个班级学生普遍存在着数学科基础知识较为薄弱,计算能力较差,综合能力不强,对数学学习有一定的困难。在课堂上的主体作用的体现不是太充分,但是他们能意识到自己的不足,对数学课的学习兴趣高,积极性强。 学生在学习交往上表现为个别化学习,课堂上较为依赖老师的引导。学生的群体性小组交流能力与协同讨论学习的能力不强,对学习资源和知识信息的获取、加工、处理和综合的能力较低。在教学中尽量分析细致,减少跨度较大的环节,对重要的推导过程采用板书方式逐步进行,力求让绝大多数学生接受。 1.理解椭圆标准方程的推导;掌握椭圆的标准方程;会根据条件求椭圆的标准方程,会根据椭圆的标准方程求焦点坐标. 2.通过椭圆图形的研究和标准方程的讨论,使学生掌握椭圆的几何性质,能正确地画出椭圆的图形,并了解椭圆的一些实际应用。 1.让学生经历椭圆标准方程的推导过程,进一步掌握求曲线方程的一般方法,体会数形结合等数学思想;培养学生运用类比、联想等方法提出问题. 2.培养学生运用数形结合的思想,进一步掌握利用方程研究曲线的基本方法,通过与椭圆几何性质的对比来提高学生联想、类比、归纳的能力,解决一些实际问题。 1.通过具体的情境感知研究椭圆标准方程的必要性和实际意义;体会数学的对称美、简洁美,培养学生的审美情趣,形成学习数学知识的积极态度. 2.进一步理解并掌握代数知识在解析几何运算中的作用,提高解方程组和计算能力,通过“数”研究“形”,说明“数”与“形”存在矛盾的统一体中,通过“数”的变化研究“形”的本质。帮助学生建立勇于探索创新的精神和克服困难的信心。
老师们、同学们:早上好!当今的教育出现了一些问题,但这些问题的出现归结为一点,就是人文精神的失落。人文精神,简单地说就是现在人们常说的“以人为本”,也就是说,要把人放在最重要的位置上,要尊重人的价值。人身上有三种东西是最宝贵的:生命、头脑和灵魂。与生命相应的教育除了狭义的体育教育,还要扩大到生命教育。今天,我和大家交流的话题就是:体育教育与生命教育。很多研究“运动与学习成绩关系”的成果都表明每天参加一小时体育锻炼的孩子学习成绩比较好。当有记者问及“全美最佳教师”雷夫教育孩子的秘诀,他说,秘诀无非有二:一是艺术引领;二是打棒球。众所周知,雷夫班上的孩子个个是棒球高手。北京汇文中学“Astrongmindinastrongbody.”(健全的头脑只寓于健康的身体之中。)的教育信条影响了一代代汇文人。清华附小窦桂梅校长提出的“体育应为小学核心课程”的理念也给了我深深地启发。现在学校的建设还在不断地完善中,近期,学校将配备上篮球架和乒乓球台,同学们还可以自带跳绳来学校。学校也会逐渐开发一些体育项目供大家进行体育活动。学校将通过体育设施的完善,体育活动的开发与实践来促进体育教育的开展。
