An Investigation Of The Eighth-grade Students Learn The Concept Of Real Numbers

The deepening of curriculum reform will inevitably lead to the corresponding changes in classroom teaching mode,the concept of class is an important lesson in mathematics teaching.In traditional lessons,there are two basic models of core concept acquisition: the pattern of mathematical core concept formation and the pattern of assimilation.So how to the concept of the new curriculum to the concept of mathematics teaching,to further strengthen the understanding of the concept of mathematics and application of students,as placed in front of a mathematical education workers in the urgent task.Therefore,the author takes the present situation of junior high school students' mathematical concept as the starting point,taking the case study of the number of real students in the year of Beijing Normal University as an example.The main problems are as follows:(1)What is the status quo of the eight-year students' real conceptual learning?(2)What are the factors that affect the conceptual learning of the eighth grade students?(3)What are the effective strategies for the eight-year students' real conceptual learning?This paper mainly uses the literature method,the examination paper examination method,the interview method carries on the research.This paper analyzes the learning situation of the real concept of the eighth grade students,and analyzes the status quo of the conceptual learning of the eighth grade students in the way of interviews and tracing.The fractal dimension is analyzed in detail from the relevant concept level of real number,the representation level of real number,the classification level of real number,the operation level of real number,the nature level of real number and the application level of real number.The real number of the concept level:(1)the real number of the concept of level,the impact of the rational number of large;(2)real representation level,the square root symbol consciousness is not strong,the number of shafts that the better;(3)real classification level,the concept of grasp is not accurate,the operation is not familiar with;(4)real The calculation level is not clear,the operation law is not thorough;(5)the real nature of the level,the square root is not enough understanding,manual estimation is weak;(6)real application level,abstract thinking better,but thecomputing power is not enough.Through the analysis of the status quo,the factors that affect the conceptual learning of the eighth grade students are:(1)student life learning experience;(2)the quality of teaching teachers and teaching attitude;(3)describe the obstacles to the distinction between the narrative and the concept;(4)the complexity of real content;(5)the convergence of high and low grades;(6)the rationality of teaching materials.The following suggestions are given for the relevant influencing factors and research status:(1)Pay attention to the real concept of build,strengthen understanding of the concept of learning;(2)Flexibility to adjust the structure of the course,the real content of the overall teaching;(3)The combination of a variety of teaching methods,teaching concepts analogy;(4)To encourage students to self-taught to guide the discussion,build a concept map to deepen the memory;(5)Study the curriculum standards,accurately grasp the real teaching requirements.
