| At present,exploring unit teaching is the need of cultivating innovative talents in the new era,the realization of new curriculum standards and the development of core qualities,and unit teaching has become a hot research topic.How to effectively implement the cultivation of students’ core quality in practical teaching has become the focus of attention.Based on this historical background,this paper focuses on the development of students’ mathematics core literacy as a perspective to carry out the research on mathematics unit instructional design,focusing on the following questions: How to build the mathematical unit instructional design process based on the concept of "three Education" ? Based on the construction process,how to carry out the unit teaching design of "equation of one variable and one time" ? What are the strategies of mathematical unit teaching design based on the concept of "Three Education" ?First of all,by reviewing the operation steps and research results of unit teaching,on the basis of clarifying the concept of "three education" and the core essentials of unit teaching of mathematics,through the concept of "learning internalization",the characteristics of mathematical unit teaching design based on the concept of "three education" are further extracted and the specific operation process of unit teaching design is constructed.Secondly,based on the constructed unit teaching operation process,the unit teaching design and teaching practice are carried out for the unit of "one variable and one time equation".By means of test paper,classroom observation,interview,student learning experience and teacher evaluation,the implementation effect of unit teaching design based on the concept of "three education" is tested.Finally,it puts forward the corresponding strategy,introspection and improvement,and further improves the mathematics unit teaching design under the concept of "three education".Through this research,the theoretical framework of mathematical unit teaching design process based on the concept of "three education" is constructed.It mainly includes four links: "learning internalized concept",preliminary analysis,development and design,and implementation and evaluation.The "learning internalization concept" link and the preliminary analysis link provide theoretical support for the preparation link and the development and design link,including the selection of unit content,the analysis of teaching elements,and the integration of teaching content.The development and design link is to compile the unit teaching objectives,carry out the unit overall planning and design the teaching process through the above analysis,so as to form the specific unit teaching design text.The development and design link is the main part of the unit teaching design process.The implementation of evaluation is to put the designed teaching design into the classroom teaching practice,according to the practice situation to reflect on the improvement and optimization of teaching design.According to the constructed process framework,unit teaching design is carried out for "one-variable equation",and a specific unit teaching design text is formed.According to the practice analysis,it is found that the implementation of mathematics unit teaching has certain effect on the cultivation of students’ mathematics core literacy.According to this research,the author puts forward the strategy of unit teaching design: attaching importance to the study of related theories and enriching teaching methods.In-depth study and analysis of curriculum standards and textbooks,standing on a higher Angle to carry out curriculum design.Focus on core knowledge(big concept)research and development,to point with surface.Stick to core literacy and set unit goals.According to the design concept,the unit overall planning.Based on the cultivation of core quality,design teaching process by unit thinking.Advocate multiple evaluation and promote effective teaching. |
