This article takes the systematic errors in the "Verification of Boyle's Law" DIS experiment as the object, explores the sources of error, and proposes four methods to reduce systematic errors, including "compensation volume method", "increasing volume method", "oil sealing method", and "push-pull improvement method". During the process of scientific exploration, it aims to cultivate students' Problem Evidence Awareness and scientific demonstrating ability. The experimental design scheme and teaching ideas proposed in the article can used to cultivate students' scientific thinking, scientific inquiry, and scientific spirit, ultimately improving their problem-solving ability.
