“示错情境”是一种最新的教学方式,在数学教学中合理地设计,不仅能够引导学生反思错误观念,而且能提高学生学习的主动性与积极性,提高创新能力。因此,教师在高中数学教学营造“示错情境”至关重要,这不仅符合新课改要求,满足学生掌握数学知识的需求,更是提高数学教学效果的明显需求,也是培养后继人才的有效手段。1营造新课“示错情境”在新教学内容导入之前,教师应该认真营造和设 “Misrepresentation situation ” is a newest teaching method, which is designed rationally in mathematics teaching. It can not only guide students to reflect on the wrong ideas, but also improve students’ initiative and enthusiasm to learn and improve their innovative abilities. Therefore, teachers in high school mathematics teaching to create “wrong context ” is essential, not only meet the requirements of the new curriculum reform to meet the needs of students to master mathematical knowledge, but also to improve the mathematics teaching effect of the obvious needs, but also to cultivate successors Effective means. 1 to create a new lesson “wrong context” Before the introduction of new teaching content, teachers should carefully create and set
