| With the implementation of a new round of curriculum reform in China,education aimed at improving students’ core literacy has received increasing attention.Taking mathematics as abridge to build a "Integrated and Practice" that integrates project-based learning and interdisciplinary integration has become the future trend of education development.Developing "Integrated and Practice" in the fields of Statistics and Probability,helps to return the classroom to students and knowledge to life.Therefore,the research question is determined to be:（1）What is the current status of the implementation of the "Integrated and Practice" of Mathematics in junior high schools?What is the current status of teachers’ understanding of the "Integrated and Practice" of Mathematics in junior high schools?What to expect?（2）Based on the "Mathematics Curriculum Standards for Compulsory Education（2022 Edition）",what is the development strategy for the"Integrated and Practice" of Statistics and Probability content in junior high schools?In order to solve the first research problem,firstly,the questionnaire survey method was used to investigate the current status of teachers’ understanding of the "Integrated and Practice" of Mathematics in Tianjin junior high schools,and then the statistical analysis method and SPSS 25.0 were used to analyze the implementation status of junior high school mathematics "Integrated and Practice" Curriculum.As a result,we can understand the current status of the implementation of the "Integrated and Practice" of Mathematics in junior high schools,how teachers understand it,and what to expect.In order to solve the second research problem,the development concept,development process and development strategy of the "Integrated and Practice" of Statistics and Probability content in junior high school are initially designed,and then the Delphi method is used to consult experts and make revisions based on the opinions.Thus,the development strategy of the "Integrated and Practice" of Statistics and Probability content in junior high school is obtained.The research conclusions are as follows:（1）For Tianjin junior high school mathematics teachers,the current development of junior high school mathematics " Integrated and Practice" is not bad,and project-based learning activities are less systematically implemented.The selection of course content is mainly based on the adaptation of resources,mostly around the internal mathematics knowledge or the connection with life,and less content involving other disciplines.At present,teachers generally recognize the important value of carrying out junior high school mathematics "Integrated and Practice" Curriculum.Among them,there are certain differences in the self-evaluation of teachers of different teaching ages in the degree of understanding of the curriculum,and the self-evaluation results of novice teachers are better than those of senior teachers.Most teachers showed a positive attitude towards teaching "Integrated and Practice"Curriculum.Teachers’ main expectation for the "Integrated and Practice" is that schools can provide good software and hardware resources and strengthen the training of teachers’ related content.（2）There are 13 "Integrated and Practice" development strategies of Statistics and Probability content for junior high school by research,including four aspects:goal setting,content selection,implementation design and evaluation design.In terms of goal setting,it mainly covers:"developing core mathematical literacy","developing data concept,model concept and reasoning ability","developing innovation awareness and application awareness","developing ’four abilities’" and "developing cooperative exploration ability,language skills and reflection skills" a total of five specific strategies.In terms of content selection,it mainly covers:"reflecting the essential characteristics of statistics and probability","highlighting interdisciplinary characteristics" and "conforming to students’ cognitive level" a total of three specific strategies.In the implementation design,it mainly covers two specific strategies of "carrying out project-based learning" and "carrying out heuristic teaching".In terms of evaluation design,it mainly covers three specific strategies of "emphasizing the achievement of core literacy","emphasizing process evaluation" and "diversification of evaluation subjects".Suggestions for improving the implementation status of "Integrated and Practice" of Mathematics in junior high schools:Simultaneous theoretical learning and teaching accumulation to help the development of project-based learning;strengthening interdisciplinary knowledge learning to promote the improvement of teachers’ abilities;enhancing the openness of topics and oriented to attach importance to interdisciplinary Comprehensive Practice.Suggestions for promoting the development of "Integrated and Practice" of Mathematics in junior high schools:select the curriculum content that conforms to students’ cognition;curriculum implementation leads students to consider. |
