A Quasi-experimental Teaching Research For Cultivating Students' System Thinking Skills

System thinking skills,as one of the necessary thinking abilities for middle school students to develop core literacy,play an important role in student learning and development.Combined with the biological background,it refers to the place where the biological phenomenon occurs as the boundary,by distinguishing the composition and structure of the life system,and then clarifying the relationship between the components,and analyzing how the life system operates to maintain its stability.Thinking skills.Theoretical and practical research at home and abroad has shown that cultivating students' systematic thinking skills helps students learn biology courses.At present,most of the research on system thinking in our country tends to regard the teaching link as a system,and there are few related researches on cultivating system thinking in combination with the specific content of biology.Therefore,this research aims to explore the impact of teaching classrooms that point to the cultivation of systems thinking on the process of middle school students' learning photosynthesis,and to propose teaching suggestions.This paper investigates the status quo of systematic thinking skills in biology among 883 senior high school students in four high schools in Jiangxi Province,using the scale of systematic thinking skills in biology compiled by ourselves as a measuring tool.In view of the deficiency of system thinking skills,two classes of a senior high school in Jiujiang City were taken as the experimental group and the control group to carry out the teaching experiment research.The experimental group was intervened,that is,classroom teaching under the specific teaching mode of system thinking was carried out.By analyzing the test results of concept maps and system thinking skills drawn by students in the experimental group and the control group,it was explored whether biology class with the specific teaching mode of system thinking could improve students' system thinking skills.The research conclusions are as follows:1.High school students' systematical thinking skills in biology are generally at a low level,especially lack of systematical comprehensive ability and systematical implementation ability.The main reason for the deficiency of system thinking skills is that students have not received special guidance,and system thinking skills are not students' natural thinking mode,so it is necessary to use system terms to stimulate the development of system thinking in a specific way of teaching.2.Classroom teaching under the specific mode of system thinking with system terms has a significant promoting effect on the cultivation of students' system thinking skills,and the cultivation effect of system analysis ability and system comprehensive ability is more significant.Based on the above conclusions,the following teaching suggestions are put forward: By constructing a conceptual model,the teaching content and the system thinking mode are effectively combined to teach;by strengthening the causal reasoning training to form a complex system thinking mode to enhance the system thinking skills;through the infiltration and training of multiple factors to form the cognitive habit of system thinking.
