Unit Teaching From The Perspective Of Deep Learning Research And Practice

With the effective promotion of a new round of curriculum reform,deep learning has become a new educational concept advocated by quality-oriented education.In order to pursue high-quality teaching results,it is particularly necessary to promote students' deep learning with effective teaching methods as the carrier.The holistic and systematic nature of unit teaching enables teachers to view the knowledge points learned from a higher knowledge field,and students to better master mathematical methods and mathematical ideas,develop higher-order thinking,and realize deep learning.Considering the inner unity of conic curve and the importance of teaching,it is very necessary to explore and carry out the research and practice of unit teaching from the perspective of deep learning based on conic chapter on this basis.In this paper,through literature analysis,questionnaire survey method,interview method,case method and so on,on the basis of consulting a large number of literature,introduces the related concepts and theoretical basis,and then to high school textbooks in the content of the conic unit as an example,based on the practice teaching platform,from the two main body of the teaching and the students,analyzing the present situation of teaching,and tries to combine the characteristics of deep learning and teaching,discusses the deep learning horizon,conic unit teaching design.Through questionnaires and interviews,it is found that teachers' overall grasp of deep learning theory and unit teaching design is not ideal,and students' learning barriers in the conic curve are mainly due to their inflexible grasp of knowledge points and excessive calculation.According to the theory of deep learning and the characteristics of unit instructional design,two cases of unit instructional design pointing to deep learning are given: 1)the unified definition of conic curve instructional design;2)Teaching design of variant problem solving of conic curve.Then,the classroom teaching effect analysis,teaching evaluation and reflection were carried out in experimental class A and control class B of senior two in the school.It was found that under unit teaching,students' level was significantly improved and their understanding of conic curve was more profound,which reflected the deep learning of students from the side and was conducive to the development of students' core quality.Finally,several strategies of unit teaching design under deep learning are summarized,that is,the strategy of transforming from "local design" to "overall design",the strategy of transforming from "goal independence" to "goal progression" and the strategy of transforming from "single problem" to "serial problem".The results showed that the big unit forms of classroom teaching design,reflect the integrity of classroom design and knowledge to teach and infiltration of mathematics thought,on the one hand can realize deep learning requirements,conform to the students' awareness of the law on the other hand,to promote students to develop critical and divergent higher-order thinking and creativity,to clarify the "source" reveals the essence of mathematics,the pursuit of teaching of teaching mechanism has important significance,further enrich the theory and practice of deep learning and teaching,also for the majority of teachers in the teaching of the conic how to realize the depth of learning under the domain of unit teaching and provide some references.
