一、化学概念教学的问题情境创设的缘由在化学知识体系中,化学概念是个圆心,也是化学知识体系进行辐射的半径.化学概念的知识不仅有利于学生对物质性质知识的认知和探究,更有利于学生在学习过程中将化学知识体系化,而且对物质及变化认识不只是停留在宏观的现象上,更能够准确地在微观上去分析和连接物质变化的规律,从而达到透过现象看本质的目的.同时,在化学概念形成的过程中,通过实验探究和科学模拟,大大地驱动学生的学习潜能,发展学
First, the problem of chemical concept teaching The reasons for the creation of context In the chemical knowledge system, the chemical concept is a circle, but also the radius of the chemical knowledge system radiation.Chemistry not only helps students understand the knowledge of the material properties of the nature and exploration, but more Which is conducive to students systematization of chemical knowledge in the learning process, but also understanding of matter and changes not only in the phenomenon of macroscopical, but also can accurately analyze and connect the law of material changes microscopically, so as to achieve the essence through the phenomenon The purpose of the same time, in the process of the formation of the chemical concept, through experimental exploration and scientific simulation, greatly driving students’ learning potential, development
