Research On Teaching Practice Of High School Mathematics Preview Based On Deep Learning

With the further development of learning science research,deep learning has entered the field of educational science and become the educational concept advocated by quality-oriented education under the new round of curriculum reform.In high school mathematics learning,the value and significance of pre-class preparation is undisputed.Many scholars at home and abroad have carried out researches on mathematics pre-class preparation,but there are very few studies combined with deep learning theory.In order to improve the efficiency of high school mathematics preview,this study intends to carry out teaching practice research on high school mathematics preview from the perspective of deep learning theory.First of all,this research applies the literature analysis method,by combining the relevant literature of the deep learning theory and mathematics preview,it is considered that deep learning perspective of high school mathematics preview should include four stages: clarifying preview goals,completing preview contents,summarizing methods and difficulties encountered in the preview process,and "reflection and evaluation" of preview.Secondly,this research designs a questionnaire investigating the current situation of high school students’ mathematics preview from three dimensions: preview motivation,preview strategy and preview evaluation of mathematics,and conducts interviews with high school mathematics teachers on two aspects of "views on mathematics preview" and "suggestions on mathematics preview from deep learning perspective".As the result shows: high school mathematics preview is a mere formality,and lacks emphasis and reflection;high school mathematics teachers neglect the preview guidance for students and summary of preview.Thirdly,based on the existing research results,aiming at the existing problems in high school students’ mathematics preview,this research puts forward five principles of high school mathematics preview based on deep learning,including the principle of appropriateness,the principle of structure,the principle of criticality,the principle of openness and the principle of reflection,as well as the five strategies of high school mathematics preview plan design,which includes penetrating diversified preview objectives,designing systematic preview contents,guiding comprehension-oriented knowledge construction,integrating relevant knowledge transfer,focusing on targeted reflection and summary,etc.Fourthly,guided by the theory of deep learning and based on the principles and strategies of high school mathematics preview,the high school mathematics preview plan was prepared,and the front-line mathematics teachers in S middle school were consulted to modify the preview plan based on their opinions,and two classes of senior one in S Middle school were selected to conduct teaching experimental research.At the same time,the four previews of "Monotonicity of Functions","Image and Properties of Logarithmic Functions","Basic Inequalities" and "Review of Trigonometric Functions" are selected as cases for analysis and evaluation.Finally,by comparing the results of the experimental class and the control class,and interviewing the students of the experimental class,the effect of the preview experiment is analyzed,so as to illustrate the operability and effectiveness of high school math preview based on deep learning.
