一、教学任务分析本节课的教学内容是上海市“二期课改”教材,高中《物理》第一册,第三章“共点力的平衡”.教学对象是上海市“实验性、示范性”高级中学高一学生.本节课还要求教师能在课堂教学中既要关注理科倾向性学生理科素养的培育,又要兼顾文科倾向性学生物理基础性知识的传授.二、教学目标1.知识与技能(1)知道平衡的概念.理解物体在共点力作用下的平衡条件;(2)学会运用实验的方法探究三力作用下的平衡条件;(3)会初步应用共点力的平衡条件解决一些简单的实际问题,知道候风地动仪原理.2.过程与方法(1)通过经历探究的过程,感受等效、图示、归纳、推理演绎等科学方法;(2)通过参与探索的过程,感受猜想假说、设计方案、实验探究、理论推演、得出结论的科学探究过程.3.情感、态度与价值观 First, the teaching task analysis The teaching content of this lesson is the Shanghai “two curriculum reform” textbook, high school “physics” first volume, the third chapter “a total of force balance.” Teaching object is Shanghai This class also requires teachers in classroom teaching should pay attention to the cultivation of science-oriented students of science literacy, Teaching Objectives (1) Knowledge and Skills (1) Know the concept of balance Understand the equilibrium conditions under which an object exerts a great influence; (2) Use experimental methods to explore the equilibrium conditions under which three forces work; (3) ) Will be the initial application of a total force of the balance of conditions to solve some simple practical problems, know the principle of the wind and seismograph 2. Process and methods (1) through the process of inquiry, experience the equivalent, graphics, induction, deductive and other science Method; (2) Through the process of exploration, feel the conjecture hypothesis, design, experimental exploration, theoretical deduction, draw conclusions of the scientific inquiry process.3 emotion, attitude and values
