基于核心素养下的中学化学教学研究

普通高中化学课程标准(2017版)提出学科核心素养是学生通过学科学习而逐步形成正确的价值观念、必备品格和关键能力。而化学学科素养包括“宏观辨识与创微观探析”“变化观念与平衡思想”“证据推理与模型认知”“科学探究与创新意识”等方面。经实习调研发现,基于新课改,化学不再是高中阶段理科必学科目,如何在有限教学时间完成教学任务以及如何激发学生学习兴趣是现在需要思考的问题。基于教育实践提出的相关教学问题,从建构主义理论结合新课标提出探究式教改策略。

Research on Chemistry Teaching in High Schools Based on Core Literacy

The general high school chemistry curriculum standard(2017 edition)puts forward that the core literacy of the subject is the correct value concepts,the necessary character and the key abilities that the students should gradually form through the subject learning.The literacy of chemistry includes five aspects:"macro identification and micro-analysis","ever-changing concept and balanced thought","evidence reasoning and model cognition","scientific inquiry and innovation consciousness".Through practical investigation,it is found that,based on the new curriculum reform,chemistry is no longer a necessary subject of science in senior high school.How to complete the teaching task in the limited teaching time and how to stimulate students'interest in learning are questions that need to be considered now.The article first proposes relevant teaching questions based on educational practice,then proposes teaching strategies based on constructivist theory combined with the new curriculum standards.
