一、教材分析本节讲述“北京市的天气和气候”一节中“气温和降水”内容,课标要求学生学会使用气温和降水资料绘制气温曲线和降水量柱状图。教师可以利用计算机演示整个绘制过程,学生模仿、绘制。绘图完成之后,采用以学生小组合作为主分析、归纳气候特征,最后,让学生通过阅读文字资料,分析“北京市的气候对我们的生活和生产有哪些积极的影响,又有哪些消极的影响?”使学生了解人地之间和各地理要素之间的相互联系及制约作用,从而树立科学的发展观。本节教学设计,遵循了建构主义理论和其教学模式,呈现多维互动的课堂教学形态,有利于学生的全员参与,让每个人都有收获,从而提高课堂教学的时效性。二、教学目标1.了解气温和降水是气候的两大要素,学会使用气温、降 First, the textbook analysis This section describes “weather and climate in Beijing ” section “temperature and precipitation ” content, the standard requires students to learn to use temperature and precipitation data to draw the temperature curve and precipitation histogram. Teachers can use the computer to demonstrate the whole drawing process, students imitate, draw. After the drawing is completed, we adopt the analysis of student groups to analyze and summarize the climatic characteristics. Finally, let the students read the written materials to analyze the positive impacts of Beijing’s climate on our life and production and what negative Impact? "To enable students to understand the interaction between human and geographical elements and the interaction between the role and constraints, so as to establish a scientific concept of development. This section of teaching design, follow the constructivism theory and its teaching mode, showing multi-dimensional interactive classroom teaching forms, is conducive to the full participation of students, so that everyone has a gain, thereby improving the timeliness of classroom teaching. Second, the teaching objectives 1. To understand the temperature and precipitation are two major elements of the climate, learn to use the temperature, drop
