在2014年9月17-19日举行的山东省济宁市初中化学优质课评比中,笔者执教了《原子中的电子》一课,取得了优异的成绩.在本节课的设计过程中,得到了邹城市教研室马晓成老师的悉心指导,在此,深表谢意.现将这节课的课堂实录写出来,与各位同仁共享,不当之处,请批评指正.教学目标1.通过动画、观察直观的原子结构模型,感知核外电子的分层排布,从而知道原子核外电子是分层排布的.
In Jining City, Shandong Province, September 17-19, 2014 junior high school chemical quality competitions, I coached the “electronic atom in the atom” class, and achieved excellent results in this class during the design, get Zoucheng City Department of Teaching and Research Ma Xiaocheng teacher’s careful guidance, in this, deeply grateful. Now this class lesson record, and colleagues to share, improper, please criticism and correction .Teaching Objectives 1.Animation, observe the visual Of the atomic structure model, the perception of extra-nuclear electronic hierarchical arrangement, and thus know that the atomic nuclei are layered arrangement.
