Research On The Feature Of Exemplary Mathematic Lessons In Senior High School

It is pointed out in the mathematics curriculum standard of senior high school that how to cultivate and develop the students' mathematics core literacy and improve the teaching quality is a hot issue in the current mathematics teaching and practice of senior high school.High school mathematics classroom is an important position to develop students' core literacy.High quality and efficient classroom teaching is not only an important way to train excellent talents,but also an important guarantee to improve the quality of education and teaching.Many high-quality mathematics courses have certain characteristics.Mining the common characteristics of high-quality mathematics courses in China can provide direction for better implementation of high school mathematics curriculum standards,improvement of teachers' quality and optimization of mathematics classroom teaching quality,help to improve students' classroom learning effect,and promote the reform and development of high school classroom teaching.This research attempts to explore a scientific and reasonable multi-dimensional analysis framework of high school mathematics quality course,and selects eight video courses and their corresponding teaching plans from the Ninth National High School Mathematics Quality Course in 2018 as the research object,and establishes an analysis framework including five dimensions of plan and preparation,teaching content,teaching implementation,course structure and classroom environment,with the help of nvivo11 qualitative analysis tools By using the methods of literature research,classroom observation,comparative research,this paper analyzes the common characteristics and individual characteristics of the current high school mathematics quality course in China.The research results show that the main characteristics of high school mathematics quality course in our country are: teachers are well prepared in pre class teaching plan and preparation,and the analysis of teaching materials,students' learning situation and initial ability is in place;in teaching content processing,teachers pay attention to the richness of teaching content,which can be represented by a variety of ways;in teaching implementation,teachers pay attention to guiding students to learn Learning,learning to understand and master mathematical knowledge methods and ways;in the structure of the course,most of the six links are set;in the construction of the classroom environment,teachers can encourage students to actively participate in the classroom through a variety of ways of questioning,timely feedback,and positive encouragement.However,there are some problems in the teaching design of high-quality courses in China,such as the inaccurate words used to explain the teaching objectives,not divided into three-dimensional objectives.Finally,according to the characteristics of the analysis,this study puts forwardsome teaching suggestions.So as to provide reference for the construction of high school mathematics quality courses and the improvement of students' mathematics classroom learning effect.The innovation of this study is to get the high school mathematics quality course characteristic analysis framework,and get the classroom record with nvivo11 qualitative analysis tool,so as to make in-depth analysis.At the end of this paper,we reflect on the improvement of this study,and put forward the future research.
