Warming up、Pre-reading、Reading、Comprehendingppt配套的教学设计方案

Unit 2 Sailing the oceans

warming up& reading

教材分析

1．中心话题是“航海、发现探索未知的大陆”，内陆涉及海洋航行、人类早期的航海技术、中国历史上最著名的航海家郑和、辛巴达的第一次冒险航行等。本单元的语言知识和语言技能都是依据“航海、发现探索未知的大陆”这个中心话题设计的。

2．本文目的旨在让学生了解在现代航海仪器发明以前，我们的祖先是怎样利用自然知识和一些简单的工具来对海洋进行探索。 Activities for observation, understanding and exploration of ocean involve a great deal of processing and analysis of visual information.

学情分析

1．高中年龄段的学生对周围的事物较为敏感，有自己的观点和看法，他们不满足教科书上的知识，让学生主动学习，学有所获，如上网查阅资料，获取更多的信息。

2．学生不只想把英语作为一门死记硬背的课程来学，更希望能学到知识性和趣味性兼有的内容，从英语学习中获得更多的知识和能力。

3．探究早期海洋冒险家的经历，使学生对成为航海家所应该具备的素质有一定的了解。理解说明文语言的准确性，抓住说明事物的特征，这是说明文语言的先决条件，表示时间，空间，数量，范围，程度，特征，性质，诠释，分类，举例和程序等。

学生学习活动评价设计

1.利用了单元录音设备和多媒体图片，增强了学生的听觉和视觉感官的刺激。2.注重了对课文的深层理解，培养学生各种思维训练力度。3.突出了新词语在句子中的灵活运用，无意中提高学生对语法的理解。

教学反思

1.让学生明白学习目标，站在学生角度，精心设计活动。这样学生可以完成具体的任务来学习巩固语言，积累学习经验和享受成功的喜悦。

2.课堂设计合理，结构流畅，成功地达到教学目标。

3.教授不仅是知识的传授者，还成为学习的促进者、指导者、组织者、帮助者、参与者和合作者，除了传授学生必要的语言知识外，还必须重视学生的个性和兴趣。在课堂中，教师通过多媒体技术为学生创设各种语言学习环境，提供丰富的教学资源，拓宽了学生的学习渠道和学习方式。

4.如果上这节课的后续，我会借助现代先进教学理念，从走进课文到走出课文，切入古代航海技术与现代或未来航海技术进行对比，然后用英语以说明文形式表述，当然，要结合自身学生的实际具体情况特点，因材施教，加以完善和提高教学水平。
