学生对化学的学习,在九年级之前主要来源于生活实践和小学自然课程中,仅仅是对化学的一些感性认识,缺乏理性的思考和一定的化学思维.可见,九年级学生对化学的学习还是一片空白,那么化学的入门学习就变得分外重要,如何走好这一步,就成为广大教育者研究的课题.一、更新观念,建立“以生为本”的启蒙理念学生对化学的了解主要源于对实验的好奇.对一些抽象的元素符号、化学反应,学生还比较陌生,谈不上学习化 Students in chemistry before the ninth grade mainly comes from the practice of life and primary school nature courses, only some perception of chemistry, lack of rational thinking and a certain degree of chemical thinking.Therefore, the ninth grade students to learn chemistry or A blank, then the chemistry of entry learning has become exceptionally important, how to take this step has become the majority of educators research topics. First, update their concepts, the establishment of “students-oriented” concept of enlightenment Students of chemistry Is mainly due to the curiosity of the experiment.For some abstract element symbols, chemical reactions, students are still unfamiliar, not to mention learning
