Abstract The chemical argumentation teaching is conducive to improve students' key competence of evidence reasoning.By using hydrogen detector in “sodium” teaching,quantitative detection data of hydrogen,the reaction products of metal sodium and water,can be safely and effectively visualized. Moreover,the effectiveness of the argumentation is also promoted with images using to collect energy conversion information,and the projection of Hong-he screen and Seewo platform live broadcast function to present the intuitive evidence of experimental phenomenon in hydrogen test and energy change on the whiteboard.This class also introduces picture materials that are highly consistent with the thermal imaging pictures collected in the experiment: infrared thermal image images in the process of metal sodium tumor injection,creating rich scene materials to strengthen the argumentation,and highlight the value of chemistry discipline.
