Abstract Taking selective compulsory 3 “alkyne” as example,centering on the solution of the problem of “removing a small amount of acetylene from industrial ethylene”,this paper designs teaching links such as “based on experience, putting forward the method of removing impurity”,“thinking about the new method of removing impurity according to the structure”,“evaluating the method of removing impurity through exploration”,“evaluating the new technology combined with discussion”,“summarizing and concluding to construct cognitive model”, guides students to start from the structure,to explore as the main line,to study and discuss the nature of acetylene,to clarify the use of acetylene,promotes the construction of students’ chemistry fundamental ideas such as classification ideas,particle ideas,change ideas,experiment ideas and chemical value ideas,and cultivates their innovative consciousness and innovative thinking.
