初中化学的核心观念之一就是化学元素观,其分布在不同课本的不同章节中,对化学这门学科的意义深远,建立化学元素观,能帮助学生在理解的基础上更深层次地学习化学知识,培养学习化学的兴趣.初中化学教育的重点是提高学生的科学素养,让学生在学习基本概念和原理的基础上,了解化学现象的本质,形成基本的化学观念.元素观是初中化学课程中最重要的化学观念,它是随着对知识的深入理解,由不同层次化学知识的学习积累而成.因此,元素观不可能通过短暂的学习完 One of the core concepts of junior high school chemistry is the concept of chemical elements, which are distributed in different chapters of different textbooks. It is of far-reaching significance to the discipline of chemistry and establishes the concept of chemical elements to help students to learn more about chemistry on the basis of understanding , And cultivate the interest of learning chemistry.The emphasis of junior high school chemistry education is to improve students’ scientific literacy so that students can understand the essence of chemical phenomena and form basic chemical concepts on the basis of learning basic concepts and principles. The most important chemical concept is that it accumulates with the learning of chemical knowledge at different levels with the deep understanding of knowledge, so the concept of element can not be learned through a short period of learning
