| With the continuous advancement of the new curriculum reform,new requirements have been put forward for talent training standards.Education should cultivate the character and key ability necessary for learners to adapt to social development,and deep learning comes into being.At present,many teachers do not pay attention to unit teaching.Fragmented teaching is easy to lead to the formation of isolated knowledge in students’ minds,which is not conducive to the construction of students’ knowledge system and the occurrence of deep learning.Unit teaching is an effective way to promote deep learning and deep learning is an effective way to implement the core literacy,and inequality unit is an important part of high school mathematics teaching content,it is the foundation of learning function and even the high school mathematics knowledge,therefore based on the deep learning of high school inequality unit teaching practice research is very meaningful.This paper firstly adopts the literature research method to sort out and summarize a large number of literatures,which lays a foundation for the subsequent research.Moreover,starting from the content of deep learning and unit teaching,this paper makes an in-depth analysis of the characteristics of deep learning,the connotation of unit teaching,the relationship between deep learning and unit teaching and relevant theories.Then,combined with the deep learning theory,a questionnaire is designed to investigate the deep learning status of high school students in practice schools.The deep learning status of high school students is analyzed from the three dimensions of cognition,interpersonal and self.At the same time,teachers are interviewed to summarize the current unit teaching status of high school students from the perspective of deep learning.After completing the above work,the unit teaching model based on deep learning is constructed,and the unit teaching is systematically analyzed from four aspects:selecting the unit learning theme,determining the unit teaching objectives,designing the unit teaching process,and carrying out the continuous evaluation.The unit teaching design is carried out for Basic Inequalities and Quadratic Equations and Inequalities of one Variable from the perspective of Function.And practice in practice.After practice,in order to verify whether the implemented teaching design can improve the deep learning level of high school students in mathematics,the experimental class and control class were tested at the same time.The results show that compared with traditional teaching design,unit teaching design based on deep learning can promote students’ deep learning of mathematics.Finally,it summarizes the teaching practice of inequality unit in high school under the theory of deep learning,and puts forward the shortcomings and prospects of this research. |
