小学数学人教版五年级上册《解方程》说课稿
二、说教学目标知识与技能：初步理解“方程的解”和“解方程”的含义，以及之间的联系和区别。能用等式的性质解形如X±a=b的方程，掌握解方程的格式和写法。初步学会检验某个数是否是方程的解，培养学生检验的习惯，提高计算能力。过程和方法：通过探索、讨论、交流等活动，让学生初步理解“方程的解”和“解方程”的概念。经历运用等式的性质探究方程解法的过程，体会方程的解法和等式的性质之间的联系。情感、态度与价值观：1. 学生能积极参与数学学习活动，对数学有好奇心和求知欲。2. 在观察、猜想、验证等数学活动中，培养学生的数学素养。重点：方程的解和解方程的概念，初步掌握用等式性质来解简易方程的方法。难点：区别方程的解和解方程的含义。解方程的算理。三、说教法与学法教法：新课标指出，教师是学习的组织者、引导者、合作者，充分发挥学生的主体性。根据这一理念，我在教学中通过观察、猜想、验证等方式，自主探索、自主学习。有目的地运用知识迁移的规律，引导学生进行观察、比较、分析、概括，培养学生的逻辑思维能力。学法：①让学生学会以旧引新，掌握并运用知识迁移进行学习的方法；②让学生学会自主发现问题，分析问题，解决问题的方法。
中小学教职员工请假管理制度
2、学校的中层和副职领导外出必须向校长请假；面上小学校长外出一个星期内报中心小学校长审批；超一周由中心小学校长提意见报区教育局审批。 3、学校教职工外出、病、事假应向校长请假。各校应完善学校管理工作，健全管理制度，制定本校请假制度，做好教职工的考勤管理，使教职工明确请假规定和有关待遇，做到有章可循，有法可依。 4、各校请假工作应做到有学校班子专人负责，及时登记并定期公布，并将其作为教职工的年度考核、任职考核、兑现各项福利待遇和奖励的依据。
中心校教师奖惩制度
一、人数加、减分 人数加、减分这项政策的制定，决策人考虑的是教师的工作量问题，我们认为工作量的大小不能把教的学生的多少作为考核依据之一。 第一、人数的多少不是教师甚至学校能控制的，我们也很不愿意自己的学校、自己的班级人数少。而教的人数多只不过是仅在作业批改，课业辅导上增加点量而已。
关于校园开展素质教育学习心得体会参考范文
二、 示范引导，引导孩子养成良好的学习习惯 学习是提高自身素养、增长才干的唯一途径。在日常的工作生活中，只有不断地学习、持续的学习，才能不断地增长知识、完善自我，促进自身的成长和发展，作为一个自然人是这样，但是为人父母还要担负起教育孩子、培养孩子的责任和义务，特别是作为青春期的中学生更应该多给予帮助和引导，避免出现偏差，而影响成长和学习。孩子是我们的未来和希望，孩子能否健康的成长和发展，事关社会的发展和时代的进步、事关民族的前途和命运。因此，作为父母必须首先做到率先垂范，在学习上给孩子当好向导或导游，坚决不能做帮手，引导孩子加强基础知识的学习，养成良好的学习习惯、认真思考的习惯。比如：孩子在做作业的时候遇到拦路虎，不要急着给他解题或是教给他怎样去做，而是应该给他讲关于该习题的原理、公式或带领着复习相关的内容，引导孩子自己去独立思考、独立完成，这样还能增强孩子的理解和记忆；其次是培养孩子的学习兴趣，引导孩子做到“学习快乐化、快乐学习化”
