《测量气温》是《变化的天气》单元中的第二课,教材中只编排了“测气温”这一个主题活动,教师用书中的课时建议是2课时:第1课时进行气温的观测和记录,第2课时进行数据的处理。因为学生前面已经学习了温度计的使用方法,况且一天中的气温观测和记录是个持续的过程,需要学生利用课后的时间去进行,因此教学中,我运用《科学拓展活动指南》(以下简称“《拓展指南》”)的“助学、评价、科普”三大功能,将教材和配套教辅书结合起来,较好地完成了教学任务。
“Measuring Temperature” is the second lesson in the “Changing Weather” unit. The textbook contains only thematic activities of “measuring air temperature.” The lesson time in the teacher’s book is 2 hours: Temperature observation and recording during the first lesson , The second class when the data processing. Because the students have already learned how to use the thermometer in the past, and the observation and recording of the temperature during the day is a continuous process that requires the students to use the time after class, therefore, in teaching, I use the Guide for Scientific Outreach (hereinafter referred to as “ ”Development Guide“ ”)“ aid, evaluation, popular science ”three functions, the textbook and supporting teaching and learning together, better finish the teaching task.
