Teaching Practice Of Probability And Statistics In Senior High School Under The Guidance Of Recent Development Zone Theory

The basic idea of the new curriculum is “ People-oriented,all for the development of The basic idea of the new curriculum is "people-oriented,all for the development of every student".Take students as the main body,teachers as the leader,and give full play to students' initiative.However,traditional basic education overemphasizes knowledge-based and teacher-centered.Often,in order to cope with the phenomenon of cramming in exams,teachers blindly instill it without considering whether students can really understand it,which makes students study in a passive position,with low learning efficiency,which is not conducive to students' development.Under the guidance of the theory of the zone of proximal development,taking the probability statistics of senior high school as an example,this paper determines the students' current level through pre-school tests,analyzes the shortcomings of the students' current level through the existing development level,and adopts scaffolding teaching to guide students to carry out cooperative learning.Interventions of dynamic evaluation in the teaching process help students make up for the shortcomings and reach the potential level.Finally,the research conclusions are as follows:1.After the intervention measures,the students' level in the experimental class is obviously improved,which is significantly different from that in the reference class;2.In the teaching examples of classical probability and total value rule,good teaching effect has been achieved by adopting intervention measures;3.Scaffolding teaching is adopted to establish a framework to help students climb up the scaffold step by step,but it is difficult to establish the framework because of individual differences;4.Conduct dynamic evaluation in the process,adjust teachers' teaching and students' learning according to the progress of teaching,and improve teaching efficiency;guiding students' cooperative learning is helpful to students' development with the help of their peers.
