Statistical Analysis And Thinking On The Changes Of "Student Experiments" Of Senior Middle School Physics In My Country

The syllabus(draft),curriculum standards(afterwards collectively called curriculum standards)is the minimum standards school students should grasp in their learning.It is drafted by the Ministry of Education.As the new curriculum reform continues to advance,the status of student experiment in senior high school physics teaching and assessment is changing.To study this situation,the first part of this research focuses on the total number of senior high school student experiment in senior high school physics curriculum standard after the foundation of our new nation.The author divides the content into five branches including force,heat,electricity,light and the original and then studies the number of student experiment in each branch as well as the percentage changes.The study finds that student physics experiment in senior high school is given priority to mechanical and electrical experiments,taking up around 40% of the total number of student experiment on average annually.According to the statistical analysis of the specific situations in senior high school students’ physics experiments,it finds that there are 14 frequently-conducted student experiments,among which there are 9 mechanical experiments.Teaching materials are the reference books that teachers and students rely on in the process of teaching and learning.It is also the basis of the Entrance Examination papers.Combined with the recent development requirement as well as the teachers’ and students’ feedback in the process of implementation of each teaching material annually,the second part analyses the changes of students experiment in the material in recent 3 years.The study wants to find which student experiments are “ever present”,“restored after deletion” “the newly added” and “the deleted”.And it combines the curriculum standard requests,the difficulty,the cognitive law of students and era development needs to analyze the reasons for suchchanges.Finally,taking the author’s school as the research object and based on the first two chapters,"Research on the students experiments changes in senior high school in curriculum standards over the years" and "Research on the students experiments changes in senior high school textbooks in the recent three years ",the study finds some special student experiments including: 1.There have always been 7 student experiments in curriculum standards and textbooks,among which 3 are mechanical experiments,2 are about electricity,1 is about optics and 1 is about heat.2.New student experiments have been added to the curriculum standards of the 2017 edition and the textbook of the 2019 edition.There are altogether 10 student experiments in this part,of which 3 are in mechanics,6 are in electricity and 1 is in heat.Next,combined with the core literacy education goals,and the era’s demand for innovative talent training,the research was carried out from different perspectives,such as teaching objectives and teaching key points and difficulties.Referring to the book "Innovation and Practice Analysis of Experimental Innovation Literacy Evaluation Scale for High School Physics Students" written by Lv Hongshen and Zhu mei-xia in yantai economic and technological development zone high school,the research divides the Evaluation criteria of physical core literacy into Evaluation of innovation consciousness,content evaluation and result evaluation giving different scores respectively.The calculation is based on the innovation ability evaluation formula: E=AX(C+S+I+P+D)XR(where E is the evaluation result of innovation ability,A is score of innovation awareness,C is score of experimental range,S is score of problem situation,I is score of instrument selection,P is score of experimental principle,D is score of data processing and R is score of result evaluation).From the perspective of teachers’ evaluation,the key points of the teaching design and implementation process of each student experiment are obtained.Combined with the changes of student experiments in the curriculum standards and textbooks,the teachers design improved students experiments teaching plans to highlight the experimental teaching objectives and key and difficult points revealed by the investigation results in the teaching cases.The above methods and design schemes will provide a way of thinking for the future teaching of teachers.
