Research On Teaching Design Of Junior Middle School Mathematics Unit Based On Core Literacy

With the deepening of educational reform,cultivating students’ core quality has become an important goal of contemporary education.In the case of higher and higher requirements on core literacy,the current "infusing" teaching mode of junior middle school mathematics classroom is not conducive to the development of students’ core literacy."Unit teaching" breaks through the limitations of traditional teaching design,and is an effective way to implement core literacy.Therefore,the core literacy oriented unit instructional design meets the current educational requirements.Based on core literacy,the following research on the design of junior middle school mathematics unit teaching was made in this paper: First,through the investigation of a middle school teachers in Yan ’an City on the understanding and implementation of mathematics core literacy and unit teaching,the analysis finds that teachers in the implementation of core literacy is some lack,most teachers know unit teaching,but there are limitations in the implementation process,resulting in low implementation frequency.Secondly,in view of the problems existing in the survey,more detailed steps of unit teaching design based on core literacy are established,namely:(1)unit demand analysis,teaching task analysis;(2)integration of unit contents and determination of unit objectives;(3)preparation of class objectives based on core literacy,(4)implementation of core literacy and construction of teaching activities,and(5)orientation of core literacy and the design of unit homework,which the five steps may be helpful to as guidelines for teachers.On this basis,product the concrete teaching design and practice using "quadratic function" as an example.Thirdly,the teaching effect of the experimental class and the control class were compared and analyzed by combining the process evaluation of learning record card and the summative evaluation of unit test.It is concluded that the students of the experimental class are obviously higher than the control class in abstract ability,model concept,reasoning ability,geometric intuition,arithmetic ability and application consciousness.It is proved that unit teaching design based on core literacy can promote the cultivation of students’ core literacy in quadratic function unit.Finally,the study offers the research’s conclusions and recommendations for designing unit teaching based on core literacy: attach importance to unit teaching and penetrate core literacy;clear unit teaching objectives,grasp the teaching content;planning the teaching process and arranging teaching activities;set up multiple evaluation to achieve teaching objectives.It is hoped to provide reference for front-line teachers to carry out unit teaching design based on core literacy.
