鲁科版《化学2》第二章第一节“化学键与化学反应”(第一课时)的内容是在学生学习了元素化合物、元素周期表的基础上对物质组成的更进一步的认识,旨在让学生通过化学键认识到化学反应中物质变化的本质。教材编写充分体现了宏观现象—微观解释—理论建立—解释应用—理论提升的化学学习思维过程。本节课从学生认知发展角度入手,将微粒观、微观表征方法融入探究式教学中,很好地完成了教学工作。
Luke version of “Chemistry 2” the first two chapters “chemical bonds and chemical reactions ” (the first class) is the content of the students learn the elemental compounds, the periodic table based on the further understanding of the material composition , Designed to allow students to recognize the nature of chemical changes in the chemical changes through chemical bonds. Textbook compilation fully embodies the macro phenomenon - micro-interpretation - the establishment of theory - to explain the application of theory to enhance the chemistry learning thinking process. This lesson starts with the cognitive development of students and integrates the concept of microparticles and microscopic representation into inquiry-based teaching, which completes the teaching work well.
