过去我们往往认为初中学生只学了些化学的基本概念,知道的东西很少,开展课外研究活动有困难。事实证明,这种看法是不正确的。由于大家的努力,本学期我校的化学课外研究小组的活动比较活跃,且有一定的收获。现在把我们的活动情况介绍于下,希望收到拋砖引玉之效。我们在组织课外研究小组时,首先提出了明确的目的要求,就是要求学生在一般课程学好的基础上进行研究活动,通过活动,培养学生热爱科学的精神和独立思考的能力,并使学生熟悉各种仪器的使用方法,进而获得熟练的操作技能。在这样的目标下,我分析了具体情况,根据可能的条件,结合课内学习,订出活动计划。按照计划,我们本学期主要进行了以下几项活动:(一)水和锌的作用,氧乙炔吹管和木材干馏 这
In the past, we often thought that junior high school students only learned some basic concepts of chemistry, they knew few things and that it was difficult to carry out extra-curricular research activities. Facts have proved that this view is not correct. Due to everyone’s efforts, this semester of our chemistry extracurricular research team activities more active, and have some gains. Now introduce our activities in the next, hoping to receive the effect of attracting bricks and stones. When organizing the extra-curricular research team, we first proposed a clear purpose and requirement. We asked students to carry out research activities on the basis of learning from normal courses. Through activities, students were encouraged to love the spirit of science and their ability to think independently. The use of instruments, and then get skilled operating skills. Under such a goal, I analyzed the specific situation and formulated the activity plan according to the possible conditions and in-class study. According to the plan, we mainly carry out the following semester activities: (A) the role of water and zinc, oxyacetylene blowing and wood distillation of this
