“我们班今天做了‘二氧化碳制取和性质的分组实验’,就在我刚要强调实验注意事项时,就有学生说他们组的试管被小组长弄坏了。走近一看,试管底出现了个小洞。我并没有严厉地批评他,而是让该组讨论问题出现的原因。当有学生指出可能因为添加实验药品的顺序不正确时,我因势引导大家思考装入石灰石的正确步骤。最后的解释是,组长先装液体后装固体,造成试管破裂。”像上述有关“课堂教学生成性问题”的论坛活动,在卢龙县各学校的教研活动中随处可见,它是卢龙县为打造“教育名县”而开展“教师团队研修”活动的重要环节。
“Our class did a carbon dioxide capture and nature grouping experiment today,” and just as I emphasized experimental considerations, students were told that their test tube was ruined by the team leader. I did not criticize him harshly, but let the group discuss the reasons for the problem.When a student pointed out that the order may not be correct because of the addition of experimental drugs, I set out to lead people to consider the situation due to load limestone The final explanation is that the leader first loaded the liquid after loading the solid, resulting in rupture of the tube. “Like the ” classroom questions about the generative problems “forum activities, Lulong County, teaching and research activities in various schools It can be seen everywhere that it is an important link for Lulong County to carry out ”teacher team training “ activities in order to create ”educational county ".
