The Research Of Text Analysy-based Problem Situation Setting On Cultivating High School Students' Physical Problem Posing Ability

The 21 st century is the information age,which has put forward the new request to the talent training standard.Cultivating innovative talents is the basic requirement to ensure the competitiveness of all countries.In response to the call of the Times,the new curriculum reform of physics requires the cultivation of students' innovative spirit and practical ability.Proposing valuable questions can stimulate students' creativity,Therefore,in the process of science education,it is very important to develop students' ability to ask questions.On the basis of understanding the current situation of students' questioning in classroom teaching in China,this study further analyzes the influence of problem situation setting on the cultivation of high school students' questioning ability.So as to provide reference for teachers to create problem situation and improve students' questioning ability.Teaching objectives play the role of motivation,orientation and evaluation in teaching activities.By analyzing teachers' teaching objectives,we can grasp the key and difficult points of classroom teaching.In order to understand the current situation of Chinese students' questioning in actual teaching,this paper analyzes more than 200 teaching target texts selected from the website of " One Division,one merit class ",and verifies the focus of teachers' setting of teaching target and the importance of putting forward the question target by using quantitative research method.The results show that teachers pay more attention to students' understanding of knowledge,applying knowledge to real life and understanding the principles of knowledge to experience the process of inquiry in setting teaching objectives.However,it is also found that even in the teaching design of ministerial and provincial excellent grades,the teaching design with the goal of cultivating students to "raise questions" is relatively few,so it can be seen that teachers still need to pay more attention to it.In physics class,to guide students to raise questions,teachers need to create a scientific problem situation.According to the situation of the problem and the existing life experience,the students put forward questions worthy of exploration,and the spirit of innovation and the consciousness of inquiry will be greatly improved.The research on the creation of problem situation is mainly based on the teaching experience summary of the front-line teachers,or through the summary of teaching design cases to set up.However,the scientific selection and analysis process of instructional design cases have not been explained accurately,which is lack of rigor.In this paper,text analysis is carried out on the problem raising link of the selected teaching design,so as to obtain a more accurate and comprehensive way to set up the problem context.In the process of text analysis,the BICOMB 2 software is firstly used to conduct word frequency statistics on the text to obtain the key points of the text preliminarily.Then the keyword co-occurrence technology is used to obtain the potential connections between keywords.The UCINET 6 software is used to conduct social network analysis on the obtained keywords to obtain the correlation between keywords.The SPSS 22 software is used to conduct clustering analysis on the obtained similarity matrix,and the clustering tree diagram can be obtained by clustering analysis.Combining with the multidimensional scaling analysis of the different matrix,the knowledge map of the proposed problem can be drawn.According to the above text analysis results,five kinds of situation setting methods are obtained,which are summarized into two categories.Namely,setting intuitive problem situation and using cultural knowledge to set problem situation.Then an experimental study is carried out and two experimental classes and one control class are set up.Class three of the experimental class put forward the problem link using the intuitive problem situation.Class four of the experimental class uses the cultural knowledge to set the problem situation.Class two adopts the form of teacher's asking and student's answering questions.Different teaching designs are developed to carry out experimental teaching,and students' questioning ability is tested by standard questionnaire and scoring criteria.After the implementation of the education experiment for one semester,the number of questions raised by the experimental class is higher than that of the control class,which is statistically different.The number of questions in the first level of the control class is significantly different from that in the experimental class,and the control class is significantly more than the experimental class.In the second level,the number of questions in the control class is less than that in the experimental class,which is statistically significant.At the third level,there is no significant difference in the number of questions in the class that used cultural knowledge to set the situation compared with the control class,while there is a significant difference between the control class and the intuitive situation.There is a significant difference between the fourth level problem quantity control class and the class with intuitive problem situation,but there is no significant difference between the fourth level problem quantity control class and the class with intuitive problem situation.Therefore,teachers should set up scientific problem situation,especially intuitive problem situation,in the process of raising questions,which can not only enhance students' perceptual understanding,conform to the content of intuitive teaching,but also promote students to raise in-depth questions.
