Comparative Study On Chemical Learning Difficulties Among Different Learning Level Students

Teaching students in accordance with their aptitude has a long history as an important teaching principle.This is because teaching students in accordance with their aptitude is not only a teaching principle,but more importantly,it contains the principle of justice in education.Different types of students may not necessarily have the same learning difficulties in their learning experiences and cognitive processes.It is difficult for the instructor to ask the teacher to analyze the difficulty and difficulty of each student in the class.Teachers are more directed at the problems that exist in a group of students.This study investigated and compared the difficulties and difficulties in the chemistry learning process of students of different academic levels,and made significant tests on the differences between groups.Based on the scientific learning theory and the learning style theory,the teaching suggestions for teachers to guide students to learn difficult points and break through the learning methods are proposed.The study conducted a survey of the chemistry learning difficulties of high school students of different academic levels by taking the Pedestrian Edition of High School Chemistry 1 as an example.Learning difficulty detection is divided into two parts: knowledge difficulty detection and chemical ability difficulty detection.The difficulty of chemical learning is divided into two parts: chemical knowledge difficult point detection and chemical ability difficulty point detection.The test method is used for the difficulty detection of chemical knowledge,and the questionnaire method is used for the detection of chemical ability.At the end of the first semester of the first year of high school,the learning difficulties of the three types of students in the high school chemistry compulsory 1 were determined by the scores and scores of the students in the test papers of the top,middle and poor students.The difficulty of the knowledge found that the students with excellent academic performance in the cultivating high school chemistry compulsory 1 difficult to learn from easy to difficult: material amount,non-metal and its compounds,classification of substances,solution preparation,metal and Its compound,chemical basic experiment synthesis.The students with average academic performance in the PEP version of the high school chemistry compulsory 1difficult to learn from easy to difficult: dispersion,solution preparation,redox reaction,ionic reaction,amount of substances,metals and their compounds,classification of substances,non-metal and its compounds,chemical basic experimental synthesis.Poor academic performance in the Pedestrian Edition of high school chemistry compulsory 1 knowledge difficult to sort from easy to difficult: separation and purification of the mixture,classification of substances,dispersion,solution preparation,redox reaction,redox reaction,ion reaction,non-metals and their compounds,metals and their compounds,chemical basic experimental synthesis,the amount of matter.Difficulties in chemical ability found that students with excellent academic performance have barriers to association;students with average academic performance have memory,calculation and association;students with poor academic performance have reading,memory,calculation,reasoning,experiment,Chemical language,impaired ability to imitate.According to the significant test of chemical ability in the three groups of students,it is found that students with poor academic performance and students with poor academic performance are significantly weaker than students in reading ability,memory ability,computing ability,reasoning ability and related ability.Students with excellent grades.Students with average academic performance and students with poor academic performance are similar in reading ability,memory ability and related ability.Students with poor academic performance are significantly weaker than middle school students in terms of computing ability,reasoning ability and experimental ability.In the difficult cause survey,the author mainly used the questionnaire method and interview method.The self-regulated learning strategies,learning psychology,and learning style of students with excellent academic performance,students with high academic performance,and students with poor academic performance were investigated.This paper directly analyzes the influence of three factors,self-regulated learning strategy,learning psychology and learning style,on the formation of chemistry learning difficulties in three types of students,and indirectly analyzes the influence of teacher factors on the formation of students' learning difficulties.Through interviews,interviews were conducted to interview the learning situation of three special and representative students as a supplement to the study.Through the investigation of students' difficult points and the analysis of the causes of difficulties,this paper puts forward some suggestions for cultivating students' breakthrough strategies,in order to provide teaching reference for frontline teachers.
