| On March 30,2014,the Ministry of Education issued the "Opinions on deepening the Ministry of Education curriculum reform,the implementation of basic task of establishing moral education." It clearly stated that the core literacy system should be used as the basis to determine the students ' The core literacy level that should be possessed,teachers should accurately grasp the depth and breadth of teaching,so that talent training requirements can be correctly reflected by exam evaluation.Therefore,one of the key points of our country's education reform must be to establish an evaluation index system that is integrated with the school stage and discipline.At the same time,in the new round of primary and secondary school mathematics curriculum reform,"Compulsory Education Mathematics Curriculum Standards" put forward ten core mathematical qualities.Education(2011 Edition)are important goals of mathematics curriculum and teaching,and it seems that building their evaluation index system especially important.Therefore,studying the evaluation index system of primary school mathematics geometry literacy has practical significance.It not only helps basic education researchers and practitioners to deepen their understanding of geometry literacy literacy,and further thinks about the role of geometry literacy literacy and educational value,and deepens the reform of basic education curriculum.Help teachers more accurately grasp the depth and breadth of teaching,adjust and improve teaching based on core literacy,and cultivate and develop students' geometric literacy in practice.The specific research process of this study is as follows: First,the literature method is used to sort out and summarize the literature on primary school mathematics geometry intuitive literacy;determine the concept of primary school geometry geometry intuitive literacy;summarize the operational definition of primary school mathematic geometry intuitive literacy;according to indicators The basis and principles of the construction,through the literature method and interview method to sort out and determine the first-level indicators,again combing and analyzing the relevant literature to determine the second-level indicators corresponding to each first-level indicator,and preliminary construction of the primary school mathematics geometry intuitive literacy evaluation Index system;then use the expert consultation method to issue questionnaires to experts,use SPSS22.0 for data analysis,and modify some primary and secondary indicators in the primary school mathematics geometric intuitive literacy evaluation index system.The consistency analysis of the first and second rounds of expert opinions was carried out,and the analysis found that the opinions of the two rounds of experts had high consistency,and determined the primary and secondary indicators of primary school mathematics geometric intuitive literacy evaluation;finally,the experts were used The weighting method is used to determine the weights,and an intuitive index system for mathematics geometric literacy evaluation in elementary schools is established.The main results of this study are as follows:1.Primary mathematics geometry intuitive literacy evaluation index system includes three first-level indicators of "using physical description and analysis of problems","using symbol description and analysis of problems" and "using graphic description and analysis of problems".Among them,the first-level indicator "use physical description and analysis problems" includes three second-level indicators: "use physical description problems","use physical analysis problems" and "use physical objects to solve problems";and the first-level indicators "use symbol description and analysis" "Problems" includes three secondary indicators: "Using symbols to describe problems","Using symbols to analyze problems" and "Using symbols to solve problems";of which,first-level indicators "Using graphics to describe and analyze problems" includes "Using graphics to describe problems",Three secondary indicators: "Using graphics to analyze problems" and "Using graphics to solve problems".2.Calculate and determine the weight coefficient between each index.The weights of the three first-level indicators "use physical description and analysis problems","use symbol description and analysis problems" and "use graphic description and analysis problems" are: 0.28,0.35,0.37;"use physical description and analysis" The weights of the three second-level indicators under the first-level indicator "description of problems using physical objects","analyzing problems using physical objects" and "solving problems using physical objects" are: 0.0896,0.1064,0.084;The weights of the three second-level indicators "Description and Analysis of Problems","Description of Problems with Symbols","Analysis of Problems with Symbols" and "Solution of Problems with Symbols" under the first-level indicators are: 0.098,0.133,0.119;The weights of the three second-level indicators under the first-level indicator "Using graphical description and analysis problems" "Using graphical description problems","Using graphical analysis problems" and "Using graphical problem solving" are: 0.1184,0.148,0.1036.The innovative point of this research is the use of a systematic analysis method that combines qualitative and quantitative analysis,the experience judgment of experts and teachers and scientific analysis,and innovatively adopts a bottom-up empirical research form to construct primary school mathematics geometry Intuitive literacy evaluation index system. |
