smartboard。2、能促进学生的研究性学习。电子白板的浮动面板功能，可以让教师对景观地图、地图、结构图、格局图或停止播放的动画、视频进行素描和讲解，就像在电子白板上添加了一个浮动的透明面板。可以引导学生探索问题。例如，在地理课上，当老师正在谈论??大规模的海水运动吗? ?，他首先展示了一张世界洋流地图，并引导学生总结洋流的特点。学生们得出结论，北半球在中低纬度地区是顺时针方向的，南半球也是如此。中低纬度海流为逆时针方向，北半球中高纬度海流为逆时针方向。但是，学生很难直接搜索洋流的分布。老师可以喊出世界的气压带和风带分布图，让学生可以发起社团活动。学生可以根据地图看到洋流和盛行风的关系，然后利用气压带和风带分布图进行推断。 The distribution of the world's ocean currents. Finally, let the students compare with the actual distribution of ocean currents. Such a process is the process in which the teacher guides the students to conduct scientific inquiry: first, proceed from the phenomenon, observe the phenomenon, summarize the law; then propose the hypothesis, and then compare the hypothesis with the actual situation to verify the hypothesis. In this way, students not only acquired knowledge about the causes and laws of ocean current formation, but also learned a way of thinking, a way of scientific inquiry.
