高中化学学科关键能力的测评及教学建议

Assessment and Teaching Suggestions on Key Competence of Chemistry in Senior High Schools

学科关键能力是实现核心素养"教—学—评"一体化与落实"一核四层四翼"高考评价体系的重要纽带。系统分析关键能力与必备知识、真实情境、核心素养之间的关系,提出化学学科关键能力测试维度,并配以典型试题分析,得出基于学科关键能力培育的教学改进建议:遴选适切的教学情境,培育信息获取与加工能力;基于证据合理推理,抓住核心要素进行模型构建;设计综合实验任务,在问题解决中感悟系统思维。

The key competence of the discipline is an important link between the integration of "teaching-learning-evaluation"of core literacy and the implementation of "one core,four layers and four wings"college entrance examination evaluation system. This paper systematically analyzed the relationship between key competencies and essential knowledge,real situation and core literacy,and proposed the key competence test dimensions of chemistry discipline. With the analysis of typical test questions,the paper drew suggestions for teaching improvement based on the cultivation of key competences of the discipline:selecting appropriate teaching situation,cultivating the ability of information acquisition and processing;based on rational reasoning of evidence,grasping the core elements for model construction;designing comprehensive experimental tasks,and understanding systematic thinking in problem solving.
