五线式教学模式在高中化学教学中的应用

Application of Five-Line Teaching Mode in High School Chemistry Teaching

摘要: 新课标倡导有效利用化学史实来培养学生的化学学科核心素养，将化学史教育有效融入中学化学教学中。本文基于化学史的融入，提出了五线式教学模式，“五线式”教学模式中的五条线分别为“历史线”、“问题线”、“活动线”、“知识线”、“素养线”。在进行教学时，应遵循系统性原则、真实性原则、适度性原则、教育性原则。以化学史事件创设情境，利用情境提出问题，依靠化学实验和课堂讨论等活动帮助学生获取知识，进而培养学生的化学学科核心素养。以“原电池”一节为例，沿着伽伐尼发现动物电流、伏打发明伏打电堆和丹尼尔发明双液原电池的化学史，帮助学生实现单液原电池、双液原电池模型的建构。

Abstract: The new curriculum standard advocates the effective use of chemistry historical facts to cultivate students’ core quality of chemistry discipline, and effectively integrate chemistry history education into middle school chemistry teaching. Based on the integration of chemistry history, this paper puts forward the five-line teaching mode. The five lines in the “five-line” teaching mode are “historical line”, “problem line”, “activity line”, “knowledge line” and “literacy line”. In teaching, the author should follow the principle of systematization principle, authenticity principle, moderation principle and educational principle. Chemistry teachers can create a situation with chemical history events, use situations to ask questions, rely on chemical experiments and classroom discussion and other activities to help students acquire knowledge, and then cultivate students’ core literacy of chemistry. Taking the section of “primary battery” as an example, along the chemical history of discovering animal current, which photovoltaic invented photovoltaic reactor and Daniel invented the double liquid primary battery, we help students to realize the construction of single liquid primary battery and double liquid primary battery model.
