A Study On The Teaching Of High Schoolstudents’ Mathematical Operation Ability ——Taking Number As An Example

In 2018,the State issued the "General High School Mathematics Curriculum Standard（2017 Edition）"（hereinafter referred to as the "Curriculum Standard"）,pointing out that the core mathematical literacy includes mathematical abstraction,logical reasoning,mathematical modeling,data analysis,mathematical operation and intuitive imagination literacy.Among them,mathematical operation literacy,with extensive basic characteristics,is an important part of the core literacy.Sequence knowledge is an important part of middle school mathematics,which involves a large number of mathematical formulas,rules and so on,the operation process is complex,greatly affecting the correctness of the results of operation,so as to determine the number as the research content of mathematical operation ability teaching research topic.The study used literature method,test paper method,interview method and classroom observation method.Through the literature method to understand the senior high school number teaching related research and mathematical operation ability related research,research background and related theories have a deeper understanding;Through the test paper method,to understand the students at the present stage of mathematical operation ability and sequence of learning status,from the perspective of operation to analyze the status of students;Through classroom observation and teacher interview,we can understand the teaching status of sequence from multiple angles and levels.Lay a practical and feasible foundation for this research.Firstly,four key elements of mathematical operation ability are determined,and the contents of sequence are sorted out based on the key elements.Secondly,according to the test papers,interview records and classroom observation,the conclusions are drawn to diagnose the problems existing in students’ mathematical operation and classroom teaching.Then,the teaching analysis based on mathematical operation is carried out,and the key elements of mathematical operation ability are combined to put forward a targeted and operable teaching strategy: in-depth analysis of the essence,understand the operation object;Through the derivation process of demonstration formulas and rules,the knowledge block diagram is constructed to strengthen memory and enable students to master operation rules skillfully.Rich operation methods,understanding algorithm arithmetic,flexible application,construct refining operation process;Strengthen self-monitoring,summarize and reflect,and then solve computing problems;Timely practice feedback,improve computing ability;Finally,according to the teaching analysis and teaching strategies,the key contents of the sequence of teaching design,in order to improve students’ mathematical operation ability.
