一、教材内容:本课是《科学》七年级下册第二章第三节的第二课时,弹力及应用弹力进行的力的测量。本节课是在学生学习了力的作用效果和力的作用是相互的基础上的进一步深入。力的种类按力的性质可分为重力、弹力、摩擦力,弹力教学是今后继续学习重力、摩擦力的基础,力的测量是弹力的一个重要应用,它使得通过力的作用效果才能感受到存在的力鲜活起来,量化起来。可见本节课教学在科学教学中举足轻重的作用。二、进行德育渗透的设想本节课运用“合作”学习的方法将教室前后座位分成10小组,每组中都有A、B、C、D四个层次的学生,“合作”意识是走向社会必不可少
First, the textbook content: This lesson is “science” seventh grade second chapter third quarter of the second class, the elastic and the application of elastic force measurement. This lesson is based on the interaction between the effect of learning a force and the effect of a force on the basis of each other. The type of force by force can be divided into gravity, elasticity, friction, elasticity Teaching is the basis for future study of gravity, friction, force measurement is an important application of elasticity, which makes the effect of force through to feel The power of living fresh, quantified. Shows that this lesson teaching plays a decisive role in science teaching. Second, the idea of moral education infiltration This class uses “cooperation ” learning methods will be divided into 10 groups before and after the classroom seat, each group has A, B, C, D four levels of students, "cooperation Awareness is essential to society
