Research On The Practice Of Cultivating Scientific Thinking Literacy Based On Model-based Teaching Strategies

"General High School Biology Curriculum Standards(2017 Edition 2020Revision)"(hereinafter referred to as "Curriculum Standards")emphasizes the importance of classroom teaching based on the development of students' core literacy of biology disciplines,among which,the cultivation of scientific thinking literacy It has a decisive influence on the overall development of students.Modeling and modeling are not only a manifestation of high school biology scientific thinking literacy,but also an important means of cultivating high school students' biology scientific thinking literacy.Model construction teaching strategy is a teaching method based on students' hands-on making models and using the resulting models to solve practical problems.When constructing,the complex text information is transformed into a model,so that it can be standardized,visualized and simplified.Through problem solving,students will be trained to change their thinking,improve the flexibility of thinking,and cultivate innovative talents for the fast-growing society.This research clarified the definition and theoretical basis of related concepts by consulting a large number of documents;using questionnaire survey method to understand the basic use of model construction teaching strategies and teachers and students' meta-cognition of model construction teaching strategies;compiling corresponding test questions and evaluation forms Understand the students' pre-scientific thinking literacy level(pre-test);construct teaching strategies based on models,and determine and implement corresponding teaching designs in conjunction with classroom introduction,promotion,and consolidation and improvement,in order to cultivate students' biological scientific thinking literacy;through classroom practice Later,through the corresponding test questions and evaluation form to understand the students' post-scientific thinking literacy level(post-test).Analyze the research results through Excel2010 and IBM SPSS Statistics21 software,and compare the differences in the level of scientific thinking literacy between students' pre-test and post-test to test the effectiveness of teaching practice based on model-based teaching strategies.The results show that 90.91% of teachers support classrooms that carry out model-building teaching activities,agreeing that the implementation of model-building teaching strategies has a positive impact on student learning,but they rarely carry out such activities due to time-consuming and lack of systematic training;students themselves The lack of understanding of model construction is due to the lack of systematic introduction of models in the textbooks,and teachers neglect the cultivation of students' modeling awareness when teaching.After teaching practice,analyzing the pre-test and post-test results of the scientific thinking literacy test questions,it was found that:(1)The pre-test results of the experimental group and the control group were different P>0.05,the difference was not significant,and the scientific thinking literacy levels of the two groups of students were similar;(2)The post-test differences between the experimental group and the control group in the conceptual model,physical model and mathematical model test questions are P=0.174(P>0.05),P=0.003(P?0.01),P=0.248(P> 0.05).The effect of constructing teaching strategies based on physical models in cultivating students' scientific thinking literacy is extremely significant,while the effects of constructing teaching strategies based on conceptual models and mathematical models are not significant,but compared with the control group,their academic performance is improved;(3)The results of the experimental group's own before and after tests showed that the effectiveness of constructing teaching strategies based on physical models was extremely significant,P=0.000**(P?0.01);the effects of mathematical model teaching strategies were second,P=0.047(0.01<P?0.05);The effect of the conceptual model construction teaching strategy is not obvious,P=0.059(P>0.05).In summary,the teaching strategy of model construction is conducive to the cultivation of students' biological scientific thinking literacy.This research has reached the following conclusions:(1)Time,knowledge reserve and ability are important factors that affect the implementation of model construction teaching strategies;(2)Students are willing to participate in model construction activities after class,and insufficient learning time will force them to give up;(3)Model-building teaching strategies can effectively improve students' classroom attention;(4)Model-building teaching strategies are conducive to cultivating students' scientific thinking literacy.In addition,this research combines the implementation of the model construction teaching case,and compiles the corresponding evaluation questions and grading rules for the three models on the scientific thinking literacy,which provides a reference for frontline teachers to cultivate students' scientific thinking literacy.
