Abstract Adhering to the concept and requirements of the 2017 curriculum standards, and according to the arrangement system of the new textbooks of Shandong Education Press Edition, the subject understanding of “reaction heat” has been systematically sorted out, including the understanding of the ontology of knowledge and the way of thinking contained in it. In order to improve students' understanding of the subject, the “reaction heat” unit is divided into 3 class hours: understanding the concept of “reaction heat” based on the system, connecting the reaction heat and enthalpy change with the help of internal energy, and calculating the enthalpy change. The driving questions (tasks) of each class hour and the evaluation of in-class and after-class homework are carefully designed and teaching practice is carried out. Compared with the whole unit teaching of this content in the previous round, reflections were made from the perspectives of teaching focus, teaching methods, and teaching effects.
