摘　　要：“离子反应”是中学化学的核心概念,也是中学化学教学的难点之一.中学生科学建构“离子反应”需大量关联概念的支撑,通过科学方法遴选“离子反应”的关联概念群,有助于促进建构主义教学模式下“离子反应”概念建构的有效性.采用文本研究、听课及访谈、问卷调查等方法初选离子反应“一般关联概念”195个,并由一线化学教师、化学教育方向研究生和化学(师范)专业本科生从中评定出离子反应“高关联概念”87个,最后通过化学领域14位大学(正)教授的专家评定,确定65个概念作为“离子反应”关联概念群.为中学化学教材的编写以及化学教育实践中科学有效开展概念教学提供参考,并为中学理科概念的“关联概念群”遴选提供研究思路与范式.“Ionic reaction”is a core concept of secondary school chemistry and one of the difficulties in secondary school chemistry teaching.The scientific construction of“ionic reaction”by secondary school students requires the support of a large number of relevant concepts.The selection of relevant concepts group of“ionic reaction”with scientific methods will help promote the effectiveness of the concept construction of“ionic reaction”under the constructivist teaching models.In this study,195 concepts were first selected as ionic reaction“general relevant concepts”through textual research,lectures and after-class interviews,and questionnaires.87 highly relevant concepts of“ionic reaction”were screened out from the 195 concepts by high school chemistry teachers,postgraduates in chemistry education and undergraduates in chemistry.Finally,65 concepts are determined as components of ionic reaction“relevant concepts group”by 14 professors in chemistry field.Aming to provide references for the compilation of chemistry textbooks in secondary school and scientific concepts teaching in chemistry education practice and provide research ideas and paradigms for selection of“relevant concepts cluster”of a concept in secondary school science.
