随着教育改革进程的不断加快,我国初中化学教学模式发生了较大改变,逐渐注重对学生进行引导式教学。初中化学虽然在整体化学体系中相对简单,但是对于刚接触化学的学生来说,其也有复杂性和抽象性的特征,如果教师直接向学生讲解相关反应式和定理,学生就很难理解其中含义,引导式教学显得尤为重要。在人教版中,绪言的设计对于学生有效学习化学知识有重要作用,能引导学生更好地了解化学概念。本文通过对人教版初中化学绪言课教学设计及点评进行深入探讨,提出一些建议。
With the continuous acceleration of the educational reform process, there has been a great change in the chemistry teaching mode of junior middle schools in our country, and the emphasis has been placed on conducting guided teaching to students. Although junior high school chemistry is relatively simple in the overall chemistry system, it also has the characteristics of complexity and abstraction for students who have just come into contact with chemistry. If the teachers explain the relevant reaction formulas and theorems directly to students, it is difficult for students to understand the meanings , Guided teaching is particularly important. In the PEP, the introduction of the preamble design for students to effectively learn the important role of chemical knowledge, can guide students to better understand the concept of chemistry. This essay will make some suggestions on the instructional design and comments of PEP curriculum chemistry introductory lesson.
