Ltd.10.26689/EIR.v4i5.15072ArticleAn Exploration of Discipline-Centered Interdisciplinary Practical Teaching in Junior High School Chemistry Under the New Curriculum Standardshttps://artdesignp.com/journal/EIR/4/5/10.26689/EIR.v4i5.15072ZhangRuidong2026452026-05-26Breaking down the barriers of single-subject chemistry teaching is now important for improving the education of introductory chemistry. As a basic subject that connects the comprehension of macroscopic matter with microscopic particle thought, junior high school chemistry is suitable for combination with other subjects such as physics, mathematics, and ethics and law. Based on the chemistry discipline, this paper specifically studies the advantages of tiered teaching in interdisciplinary junior high school chemistry education from five aspects: knowledge construction, cognitive development, ability training, moral education and teacher improvement. It investigates how the STSE educational concept enlarges the range of interdisciplinary practical activities in chemistry, thus offering a pedagogical guide for front-line chemistry teachers to carry out interdisciplinary teaching properly and promote core chemical abilities.Junior high school chemistry,Interdisciplinary teaching,Discipline-centered
