探究活动是科学课堂教学活动的中心环节。主要通过教师有效地提问问题,引领学生经历科学探究的过程。在教学《斜面》时,需要解决这样的问题:斜面有什么作用?根据实验材料和课本的提示你应设计什么样的实验验证呢?生:把橡皮筋挂在这个小车上,然后往上拉,看看橡皮筋的长度。然后让橡皮筋沿斜面拉小车,再计下橡皮筋的长度。师:你想的方法非常好。他想用直接提起和用斜面提的数据来比较。(板书:直接提用斜面提)
Inquiry activity is the central part of science classroom teaching activities. Mainly through teachers to effectively ask questions, leading students to experience the process of scientific inquiry. When teaching a “bevel,” you need to address the following questions: What is the role of the bevel? What kind of experimental verification should you design based on the materials and textbooks you are teaching? Health: Hang the rubber band on the car and pull up Take a look at the length of the rubber band. Then let the rubber band pull the car along the slope, then count the length of the rubber band. Teacher: You think the method is very good. He wanted to compare directly with the data raised and bevelled. (Blackboard: direct mention ramp)
