初中英语面试教案万能模板资料讲解

Teaching Aims:

Knowledge aim:

Students will know Lin Fei’s daily life and some good habits at their home.

Ability aim:

Students will improve their listening and speaking skills.

Emotional aim:

After this lesson students would like to learn to arrange their life and form good habit in the daily life.

Teaching Key and difficult Points:

Teaching Key Points:

Students will understand this passage by listening and make a time line of Lin Fei’s life.

Teaching Difficult Points:

How to describe their own life style of the school day?

Teaching Procedures:

Step 1 Warming-up

Do a survey:ask students to fill the questionnaire (with different daily activities and time point, students just need to mark the activities in their time) and invite some students to share.

Step 2 Pre-listening

Show some pictures about Lin Fei’s day and ask students “what does Lin Fei do in a day?

Step 3 While-listening

Play the tape recorder and ask students some question.

Q: What is the distance between his school and home?

Play the tape recorder another time and give students some other questions to practice their listening again.

Q1: When should Lin Fei go to school?

Q2: How long will it take Lin Fei to ride to the bus station?

Listen to the tape for the third time and then students should describe Lin Fei’s daily life in their own words. They will have 3 mines to prepare it.

Step 4 Post-listening

Ask students to look their questionnaires which they filled at the beginning of the class and give them 5 min to make a short story of their daily life, later some students will share the stories in front of the class.

Teacher should give them a guidance of health life style.

Step 5 Summary and homework

Summarize this lesson with students, and then ask them to design a new schedule of their daily life after the class, they will share during next lesson, they also need to read the new passage two times to consolidate the new knowledge.

Teaching Reflection

2.2.1对数与对数运算性质（二）

教学目标

（1）知识与技能：

理解对数的运算性质．

（2）过程与方法：

通过对数的运算性质的探索及推导过程，培养学生的“推理能力”、“等价转化”和“演绎归纳”的数学思想方法，以及创新意识．

（3）情感、态态与价值观：

1、利用指、对数式关系启发学生研究对数性质及运算法则培养学生注意探索、研究、揭示事物的内在联系，培养分析问题、解决问题的能力，培养学生大胆探索，实事求是的科学精神。

2、对数运算法则可以把乘、除、乘方、开方运算转化为加减乘除运算，加快了运算速度、简化了计算方法、显示了对数计算忧越性，体现了所学知识实践中的应用。

教学重点、难点

教学重点：对数运算性质及其推导过程.

教学难点： 对数的运算性质发现过程及其证明.

教学过程

（一）复习巩固，引入新课：

（1）对数的定义 b N a =log ，掌握其中 a 与 N 的取值范围；

（2）指数式与对数式的互化，及两个重要公式；

（3）指数运算法则（积、商、幂、方根）。

设计意图：对数的概念和指数的运算性质是学习本节课的基础，学习新知前的简单复习，不仅能唤起学生的记忆，而且为学习新课做好了知识上的准备．

2、请同学判断以下几组数是否相等？

（1） 10

1lg 100lg +，)101100lg(⨯； （2）8

1log 4log 22+，21log 2； 提出问题：由（1）（2）结果出发，同学们能看出他们具有一个怎样的共同点？ 设计意图：让学生观察，学会从特殊到一般，寻求规律。

新课讲解：

请同学们交流讨论得出结论，当底数相同的时候，两个正数的对数之和等于两个正数积的对数。
