Design And Practice Of Satl High School Chemistry Teaching Based On Systematic Thinking Ability Training

As a necessary thinking ability for middle school students,systematic thinking ability plays an important role in the learning and development of middle school students,and is also a necessary thinking ability for students to develop core literacy.The research on the training methods and strategies of systematic thinking ability has been widely concerned by scholars at home and abroad.In the teaching of chemistry,constructing a teaching strategy for the cultivation of systematic thinking ability and enhancing the systematic thinking ability of middle school students can help to improve the core literacy of middle school students and promote their comprehensive development.This article combines the microscopic,abstract and experimental characteristics of the chemistry discipline to discuss the design and evaluation of the SATL middle school chemistry teaching based on the cultivation of systematic thinking ability of middle school students.The main contents are as follows:1.Questionnaire surveys and interviews were used to investigate and analyze the chemistry teachers' knowledge of systematic thinking in Central Plains.The results show that in terms of personal factors of teachers,different genders of teachers have no significant difference in the cultivation of systematic thinking,and different teaching ages have no significant difference in the cultivation of systematic thinking of students.Teachers in the “40-50” age group have a stronger understanding of systematic thinking than others Age group;in terms of the selection of systematic thinking training methods,95.78% of teachers believe that the introduction of chemical life examples in teaching will help students develop their systematic thinking ability,and 91.55% of teachers believe that the construction of knowledge system diagrams will be beneficial to the cultivation of students' systematic thinking.2.Discuss the advantages of introducing systematic teaching methods in the middle school stage,establish a system thinking hierarchy model,and clarify the threeabilities necessary for the development of learners' system thinking,including system component analysis ability,component combination ability and specific implementation ability;For the purpose of improving students' systematic thinking,discuss the relevant strategies and specific requirements of the SATL teaching model in the construction of system diagrams,and summarize the teacher elements and student elements required by the SATL teaching model.3.According to the relevant design principles and methods,select "acid rain" related content for case design.In the teaching process,according to the formation of acid rain,the impact of human activities on the formation of acid rain and the microscopic reaction principle of acid rain formation,the knowledge concepts covered by the system are divided into three systems,namely: human disturbance subsystem and human elimination subsystem And the micro-change subsystem,design the system diagram and teaching content for each system separately.4.Choose experimental class and control class to carry out comparative experiments,compile systematic comprehensive test questions according to the teaching content to test the students' system thinking level,and divide system thinkingⅠ,Ⅱ,Ⅲ,Ⅳ according to the type of test questions.Using SPSS 22 to perform reliability analysis on the system comprehensive test questions,the Cronbach α values at the four levels of system thinking Ⅰ,Ⅱ,Ⅲ,and Ⅳ are 0.737,0.713,0.733,and0.683,respectively,and the α values are all greater than 0.6.Reliability is good;the Mann-Whitney U test is performed on the results of the two classes.The data shows that the P values on the four levels of systematic thinking I,II,III,and IV are 0.00,0.013,0.026,and 0.00,respectively,all of which are less than 0.05.In the divided system levels,there are significant differences between the experimental group and the control group.The data shows that on the basis of ensuring the stable performance of students,the SATL teaching model is conducive to improving students 'systematic thinking ability and cultivating students' core literacy.
