Research On Teaching Design Of High School Statistics Unit Based On "Mathematical Problem String"

With the proposal of key competencies,unit teaching design comes into being,and unit teaching design is an effective way to implement key competencies.Moreover,mathematics problem string,as an effective teaching strategy,has a significant effect on promoting the development of thinking,which is conducive to improving the effectiveness of the classroom and the implementation of the key competencies of mathematics.Therefore,both unit teaching design and mathematical problem string are the ways to effectively implement the key competencies of mathematics discipline.The research aims to carry out the teaching design of high school statistical unit based on the mathematical problem string and implement the key competencies of data analysis subject.Therefore,three research questions are set:(1)How to design unit teaching plan based on the mathematical problem string?(2)How about the implementation of the key competencies of the data analysis discipline?(3)How to improve the teaching design based on the mathematical problem string?With 46 students from a class in a senior middle school in Gaizhou,four research methods are experiment,questionnaire,interview and observation.The purpose of experimental method design is to examine the implementation of the key competencies of data analysis through the implementation of unit teaching.The questionnaire survey adopts the method of distributing class hour target detection and unit target detection and recycling to the research objects to test the achievement of teaching objectives.The pre-implementation interview is used to understand students 'learning situation,and the post-implementation interview is used to understand the improvement of the teaching plan of the unit based on the implementation of key competencies of data analysis discipline.The observation method is to observe the students 'classroom behavior,and record each class hour teaching implementation effect observation table to check the achievement of the students' unit teaching objectives.Based on the above research problems and research methods,three research conclusions are drawn:(1)The unit teaching design based on the mathematical problem string is conducive to the implementation of the key competencies of mathematics.(2)When designing unit teaching,pay attention to the connection effect of the summary problems on the class time.(3)The mathematical problems in the real situation are conducive to the teaching design of the statistical unit and implement the key competencies of the data analysis subject.According to the research conclusions,the suggestions are as follows:(1)It is suggested that teachers design the unit teaching based on the mathematical problem string.(2)It is suggested that the exercises in the statistical unit are the mathematical problems of real situations,and make the problems as open as possible.
