直观教学法是新课改下所倡导的一种新的教学方式,目的就是要将抽象的数学理论知识形象化,直观化,使学生能更好的理解和掌握数学基本知识。尤其是在信息技术发展迅速的今天,直观教学的手段也越来越多,比如:多媒体、微课、实物、图形等等,甚至还有3D打印模型技术等等,这些直观手段的辅助不仅能够给枯燥的数学课堂注入生机,提高学生的数学学习质量,而且对高效数学课堂的顺利实现,对学生数学学习兴趣的提升和数学核心素养的培养都起着
Intuitive teaching method is a new teaching mode advocated under the new curriculum reform. The purpose is to visualize and abstract the abstract mathematical theory knowledge so that students can better understand and master the basic knowledge of mathematics. Especially in today’s rapid development of information technology, there are more and more means for visual teaching, such as multimedia, micro-class, physical objects, graphics, etc. There are even 3D printing model technologies, etc. These visual aids can not only help Bring vitality to the boring mathematics classroom and improve the quality of students ’mathematics learning. Besides, the successful realization of efficient mathematics classroom, the improvement of students’ interest in mathematics learning and the cultivation of mathematics core literacy all play
