一、在高中化学反应教学中培养学生创新科学思维在高中化学反应这部分知识的教学时,要一遍又一遍地向学生讲解各种物质的化学性质和化学反应发生的条件,还要设计大量练习题课上课下进行练习,批阅一张张试卷,而学生也要一道道地做练习题,一遍遍地书写繁冗的化学方程式。在这一过程中,学生和教师都做了大量的重复性工作,身心俱疲,但教学效果并没有达到预期目标。因此笔者将高中教材中所要求的所有物质的化学式或离子符号随机排列,根据物质间发
First, in high school chemical reaction teaching students to develop innovative scientific thinking This part of the chemical reaction in high school teaching, to explain to students over and over again chemical properties of various substances and chemical reaction conditions, but also to design a lot of practice Under the class lesson practice, review a paper, and students also have to do exercises in unison, over and over writing cumbersome chemical equations. In this process, students and teachers have done a lot of repetitive work, both physically and mentally exhausted, but the teaching effect did not meet the expected goals. Therefore, the author of high school teaching materials required by all the chemical formula or ionic symbols arranged randomly, according to the material
