Unit6 Keep our city clean 教学反思

陆明霞

本单元是有关环境保护的话题，主要学习环境污染产生的原因What makes our dirty?及如何进行环境保护What can we do to keep our city clean?六年级的学生对环保这个话题并不陌生，他们已经通过各种渠道，如其它课程，媒体等对污染原因和环保的重要性，方法都有所了解，关键是他们通过本单元的学习学会如何用英文表达，也使环保意识进一步得以增强。

我所执教的是Storytime这个板块。该板块有两个话题，第一，什么造成了城市污染？第二，如何保持城市清洁。板块内容清晰，主题明确。所以在设计本节课的思路时我都是围绕着这两个问题而设计了多种情境和活动。

1. Watch and think:

出示两组对比强烈的图片，以前空气清新的城市，现在有雾霾的城市；以前干净的河流，现在被污染的河流…通过鲜明的对比，导入本课主题，学习clean, dirty.

2. Watch and answer整体感知课文

在新授部分在由学生观看动画之后，明确Miss Li 和学生在讨论“What makes our city dirty, how to make our city clean?”问题之后，由我创设问题情境“What makes the city dirty?”，先让学生带着问题，自主阅读文本第一部分，通过他们小组合作具体探讨是什么让城市的哪里变脏，问题逐层递进，解决的策略也从单薄的个人力量演变为集体的小组合作。

3. Read and answer/Read and write

自读课文，探寻环境污染产生的原因，并解决What makes our dirty?接下来，通过快速读课文，完成英语书上60页，解决如何保护环境的问题。在教学过程中我利用板书帮助学生在在头脑中建立课文的框架，使学生能进行流畅的表达。如：

4. Have an interview

在巩固环节，我利用电视台正在招聘记者的真实情境，让学生争当优秀小记者，打开学生的思维，将所学知识串联起来让学生运用。在采访的过程中让学生体会环境污染的严重性，保护环境的重要性，以及增强环境保护意识的迫切性。学生的思维和小组合作力量也很令人吃惊，表现很赞！

5. Let’s imagine

最后通过对未来城市的畅想，再次培养学生保护环境应从我做起，从小事做起，保护环境人人有责的意识，只有这样，我们未来的城市才会更美，更干净，更现代化。

纵观整堂课，在学生层面上，我缺乏大胆质疑，高年级的课堂应该是合作与质疑相结合的整体；在板书设计上，虽然自认为板书清晰且美观，但是却缺少了手写，板书确实是展现教师基本功的一种方式，我们不容忽视，所以我这节课的板书，可以把贴的图片改成短语文字，然后把文字再以简笔画的形式勾勒出来，这样一来不仅有了花朵的美，也有了教师基本功的呈现。有活动就会有收获，有反思才会有进步！我成长，我快乐；我反思，我进步！
