在教学中,要取得良好的教学效果,使学生在轻松快乐中掌握知识,不能单一地运用某一种教学方法。不同的学科不同的课型,教学方法也应有所差异。要因学情、课型结构、现有的资源而转变。在化学教学中,实验探究无疑是一种重要的教学手段,在此就以九年级化学“质量守恒定律”一课为例,对实验探究教学过程加以具体的探讨。首先,在上课时要明确问题,以及要达到的目标。这节课的问题是在化学反应中参加化学反应的各物质的质量总和与生成的各物质质量总和的关系。目标是
In teaching, to achieve good teaching results, so that students can easily grasp the knowledge, not a single use of a teaching method. Different subjects of different types of teaching methods should also be different. Due to school conditions, class structure, the existing resources and change. In chemistry teaching, experimental exploration is undoubtedly an important method of teaching. Here we take the ninth grade chemistry “law of conservation of mass ” as an example to discuss the process of experimental inquiry teaching in detail. First of all, in class to be clear problems, and to achieve the goal. The problem with this class is the relationship between the sum of the masses of the substances involved in the chemical reaction in the chemical reaction and the sum of the masses of the substances produced. The goal is
