Abstract：The purpose of this paper is to help students break through the barrier between the original knowledge points，form an interconnected knowledge logic system，promote the transfer and application of knowledge，and improve students’ability to solve real problems.Therefore，based on students’existing knowledge，this paper breaks through the established framework of traditional textbook units from the perspective of large unit teaching，reorganizing the content of the textbook and designing areasonable scaffolding to help students build a chemical thinking model underthe guidance of real situations.In the teaching process，students’ability to design experiments independently and collect data is cultivated，and their comprehensive analysis ability and problem solving capacity are finall developed，so as to promote the improvement of students’ core competencies of chemistry.

Keywords：large-unit teaching;chemical thinking model;real situation;high school chemistry;core competency
