基于化学新课标的教学策略要素、特点及建议研究

Research on Teaching Strategy Elements,Characteristics and Suggestions Based on the New Chemistry Curriculum Standard

教学策略是教师为了有效教学,在一定目标的指引下,综合考虑各教学基本要素而采取的有效措施。课程标准是教师教学的权威指导性文件,具有重要分析价值。以《普通高中化学课程标准(2017年版)》为研究对象,采取内容分析法,着重分析其中教学策略。研究发现,教学策略主要包含教学素材和教学活动两大要素,以学科核心素养为价值导向,充分体现主题特质性,必修阶段侧重学科知识结构化,选修阶段注重学科思维系统化。基于以上发现,给出教学建议:重视学科理解,发展结构化、本原性的知识体系;教学中,选择并组织功能化的教学素材,注重知识建构过程,开展多样化活动。以最大化发挥教学策略价值,践行素养为本的课堂教学。

Teaching strategy is an effective measure taken by teachers to effectively teach and comprehensively consider the basic elements of teaching under the guidance of certain objectives.Curriculum standard is an authoritative guiding document for teachers′teaching,which has an important analytical value.This paper takes the 2017 senior high school chemistry curriculum standard as research object,chooses the content analysis method as methodology,focuses on the analysis of teaching strategies.Research found that teaching strategies mainly include teaching materials and teaching activities.Teaching strategy has the characteristics of value orientation and theme specificity based on the core literacy of the discipline,the compulsory stage strategy focuses on knowledge structure,and the selective stage strategy focuses on systematic thinking.Based on the above findings,some teaching suggestions are given as follows:teachers should pay attention to understanding chemistry subject and developing structured and original knowledge system.In teaching,teacher should choose and organize functional teaching materials,pay attention to the process of knowledge construction and carry out diversified activities in order to maximize the value of teaching strategies and practice capacity-based classroom teaching.
