摘　　要：沿循化学键发展史、创设实验和文献情境、分析实验数据,引导学生自主建构化学键的概念及其表征方式。研究结果表明:基于化学史和实验数据的教学不仅能帮助学生充分理解概念的含义,在学生构建概念并解释真实问题的过程中,还能发展学生宏微结合、证据推理、科学探究与社会责任的化学学科核心素养,认识化学研究的创新方法和研究结论的相对合理性。This study follows the history of chemical bonds,creates experimental and literature situations,analyzes experimental data,and guides students to independently construct the concept of chemical bonds and their representation methods.The results prove that students can be helped to fully understand the meaning of the concept through this teaching method which based on chemistry history and experimental data.In addition,in the process of the students’building concept and solving problems,their core literacy:macro identification and micro analysis ability,evidence-based reasoning,scientific inquiry,social responsibility can also be developed and they will deeply understand innovation methods of chemistry research and the relative rationality of research conclusion.
