在化学实验教学中,有很多特殊的实验,如不易操作、有毒有害的反应物不易排除、化学现象不明显及反应慢导致课堂教学难以完成的实验等。针对这种情况,教师要以新课程理念为指导,勇于创新,利用一切有效的实验教学资源,改革实验教学的方式,提高实验教学效率,完成教学目标。一、正确改进教材实验,培养学生的创新意识创新是一个民族的灵魂。化学课程标准强调,在化学教学中,要注重激发学生学习化学的兴趣,培养学生的创新意识和实践能力。因此,在教学中根据教材的实际情况,对教材中的某些实验进行改进,既有利于实现
In chemistry experiment teaching, there are many special experiments, such as not easy to operate, toxic and harmful reactants are not easy to rule out, the chemical phenomenon is not obvious and the reaction slow lead to difficult to complete the classroom teaching experiments. In response to this situation, teachers should take the guidance of the new curriculum as a guide, innovate bravely, make use of all effective experimental teaching resources, reform the way of experimental teaching, improve the efficiency of experimental teaching and accomplish the teaching goal. First, correct teaching materials experiment to cultivate students’ innovative awareness is the soul of a nation. Chemistry curriculum standards emphasize that in chemistry teaching, we must pay attention to stimulating students ’interest in chemistry and cultivating students’ innovative awareness and practical ability. Therefore, in teaching according to the actual situation of teaching materials, teaching materials in some experiments to improve, both conducive to the realization
