在常规的科学课堂中发现,学生对谚语知识的掌握比较薄弱,教师如何在课堂中巧妙应用谚语,发挥其画龙点睛的作用成了科学老师教学研究的重中之重。《月相变化》是《宇宙》单元重要的一课。这一课先让学生画一画月相,了解月相;再给月相排序从而认识月相变化的规律性;最后模拟月相变化帮助学生认识月相变化的规律和形成的原因。如在画月相这个环节中教师就可以恰当的用谚语正确地引导出学生如何画月相。【课堂实录】1
It is found in the regular science classroom that the students’ mastery of the proverb knowledge is relatively weak. How teachers can skillfully apply proverbs and exert their finishing touch has become the most important task in science teaching. “Moon phase change” is an important lesson in the “Universe” unit. This lesson first allows students to draw a moon phase, understand the moon phase; then give the moon phase order to understand the regularity of the moon phase change; and finally simulate the moon phase change to help students understand the laws of moon phase change and the formation of the reasons. As in the painting phase of the moon, teachers can properly use the proverb to correctly guide students how to draw the moon phase. [Record in class] 1
