问题解决学习在高三化学教学中的实践——基于证据推理与变化观念分析复杂体系中的反应

以学科核心素养为导向的命题框架强调“情境”与“知识”同时服务于“问题”的提出与解决,在高三课堂教学中创设复杂实验情境,采用问题解决学习,引导学生在应用内容性知识解决真实问题的过程中,自主合作习得程序性知识和认识性知识。培养对学科的整体认识,形成严密的知识结构体系和思维逻辑,着重发展“证据推理与模型认知、变化观念与平衡思想”等学科核心素养。

Application of Problem-Based Learning in Senior Three Chemistry Teaching:Analysis of Reaction in Complex System Based on Evidence Reasoning and Changing Concepts

The core literacy oriented proposition framework emphasizes that both situation and knowledge contribute to problem raising and solving. By creating complex task situations and using problem-based learning, we guide students acquire procedural and epistemic knowledge independently in the process of applying content knowledge to solve real problems, cultivate the overall understanding of the discipline, form strict knowledge structure system and thinking logic, develop "evidence reasoning and model cognition, changing concepts and balanced thoughts".
