开展家庭小实验,提高初中化学教学质量

Carry out Family Experiments to Improve the Quality of Junior Middle School Chemistry Teaching

日常生活中随时都能遇到一些化学现象,有些现象可能会因为过于常见而导致人们熟视无睹。初中化学学习中,学生除了可以在课堂上学习化学知识,还可以从一些生活现象入手,进一步学习化学知识,探究化学王国的奥秘。由于受到环境条件的限制,教师在让学生开展家庭化学小实验时,必须充分考虑到条件的限制、实验环境的选择、实验器材的准备等要素,然后充分调动学生的学习积极性,激发学生开展化学家庭小实验的激情。实验方法上教师要对他们进行有效的指导,争取每一个实验能够达到预想的效果,从而培养学生的动手操作能力、独立自主地探究化学知识的能力。

Some chemical phenomena can be encountered at any time in daily life,but some phenomena happen frequently and people ignore them.In junior high school chemistry study,students can not only learn chemistry knowledge in class,but also start with some life phenomena,further study chemistry knowledge,and explore the mysteries of the kingdom of chemistry.Due to the restriction of environmental conditions,teachers must fully consider factors such as the restriction of conditions,the choice of experimental environment,and the preparation of experimental equipment when letting students conduct small home chemistry experiments,and then fully mobilize students'enthusiasm for learning and stimulate students to develop chemistry The passion for family experiments.In terms of experimental methods,teachers should provide effective guidance to them,and strive for each experiment to achieve the expected results,so as to cultivate students'hands-on operation ability and the ability to independently explore chemical knowledge.
