学习者分析在生活中,学生已经初步了解金属的相关知识。但所了解的知识尚未系统化;同时学生已具备了一定的实验设计探究能力,控制变量的环节还有待提高。整节课学生会觉得“好玩,有趣,不会用”。所以教师在教学设计中需要重点关注:1重点激发学生的学习热情并使这种热情能延续甚至高涨。(如:好的引入,问题串的设计,图片资料、视频,增加实验给学生意外的惊喜)2.注重具体方法的指导和落实。(如:如何设计实验?设计实验时如何控制变量?)3.注重方法的归纳
Learner Analysis In life, students have an initial understanding of the relevant knowledge of metals. However, the understanding of the knowledge has not been systematized; at the same time, students have acquired certain experimental design and inquiry ability, and the link of controlling variables has yet to be improved. The whole class students will think “fun, fun, not used ”. Therefore, teachers need to focus on teaching design: 1 to stimulate students enthusiasm for learning and to make this enthusiasm can continue or even high. (Such as: good introduction, the design of the problem string, picture information, video, increase the surprise of the students to the experiment) 2. pay attention to the guidance and implementation of specific methods. (Such as: How to design experiments? How to control variables in designing experiments?) 3. Focus on the induction of the method
