Research On The Design And Implementation Of Interdisciplinary Project-based Teaching Cases In Junior Middle School Mathematic

Under the background of the information age,the demand for innovative talents with comprehensive quality has increased sharply,and the reform trend of basic education is towards integration,aiming at breaking the barriers of disciplines and uniting all disciplines to solve problems.At present,Mathematics Curriculum Standard for Compulsory Education(2022 Edition)clearly puts forward that interdisciplinary project-based teaching activities should be carried out in the field of comprehensive practical activities in junior high schools,aiming at solving real problems and improving students’ necessary ability and quality to adapt to life in the 21st century.However,by combing the research results of interdisciplinary teaching of mathematics at home and abroad,it is found that the theoretical research is relatively perfect,while the practical research still has a lot of room for development and filling.In order to implement the requirements of national curriculum standards for the cultivation of students’core literacy,developing interdisciplinary project-based teaching cases of mathematics suitable for practical teaching has become the basis and key to promote the smooth implementation of interdisciplinary education.Therefore,this study focuses on the following three issues:1.How to design the interdisciplinary project-based teaching of junior high school mathematics?2.How to implement interdisciplinary project-based teaching in junior high school mathematics?3.How to evaluate the effect of interdisciplinary project-based case implementation in junior high school mathematics?This study takes mathematics as the center,combines the concept of interdisciplinary project-based teaching design,selects the content of "Mosaic of Plane Graphics" in the comprehensive practical course of the eighth grade of People’s Education Press,and designs and implements the interdisciplinary teaching case of junior high school mathematics under the guidance of ADDIE teaching model.First of all,this paper sorts out the relevant literature about interdisciplinary teaching,project-based learning and interdisciplinary project-based learning at home and abroad,analyzes the integration of interdisciplinary teaching and project-based learning mode,and discusses how to design and develop interdisciplinary teaching cases of junior high school mathematics with project-based learning teaching mode;Secondly,under the guidance of constructivist learning theory,multiple intelligences theory,pragmatic learning theory and ADDIE teaching design theory,the activity flow of interdisciplinary mathematics projects is completely constructed,and it is refined layer by layer and put into operation.Thirdly,relying on the activity flow constructed in the early stage,we developed a specific lesson-Mosaic of Plane Graphics,and carried out teaching practice in Urumqi B Middle School.Finally,through questionnaires,interviews between teachers and students,classroom observation and students’ achievements,this paper analyzes the implementation effect of interdisciplinary project-based learning of "Mosaic of Plane Graphics"from three dimensions:students’ mastery of knowledge and skills,improvement of core literacy and formation of emotional attitude.The results of this study are as follows:1.It is feasible to design and implement interdisciplinary project-based teaching of junior high school mathematics with ADDIE model.2.The current teaching methods have not effectively implemented the training requirements of students’ comprehensive ability.3.The interdisciplinary project-based learning of junior middle school mathematics is conducive to cultivating students’ core literacy.4.Developing interdisciplinary mathematics project activities is beneficial to both teaching and learning.5.Online interdisciplinary teaching has limitations.According to the case implementation of interdisciplinary project-based learning in mathematics,the following teaching suggestions are put forward:1.Studying Standards(2022)is the most important knowledge reserve for designing and implementing interdisciplinary teaching.2.Effective student-oriented classroom activities must become the normal state of teaching.3.Teaching is connected with life.4.Pay attention to the operability of interdisciplinary projects.5.Helping students get familiar with the evaluation criteria in advance is helpful for the activities.
