众所周知,化学这门学科起源于实验,发展于实验,成就于实验。但当前农村教育经费不足,师资力量薄弱,实验教学难以正常开展。学生实验呈现出“一高二低三不强”的状况。即:理论水平高;观察能力低,动手操作能力低;探究创新能力不强,分析问题、
As we all know, chemical discipline originated in the experiment, developed in the experiment, achievement in the experiment. However, the current lack of funding for rural education, teacher strength is weak, experimental teaching difficult to carry out normally. Students experiment shows “a high two low three not strong” situation. Namely: high theoretical level; low observing ability, low practical ability to operate; ability to explore innovation is not strong, analysis of the problem,
