Study On The Optimization Design And Evaluation Criteria Of High School Geography "Soil And Hydrology And Vegetation" Simulation Experiment

Knowledge related to “soil,hydrology and vegetation” is an important part of high school geography.At the same time,these three elements are closely related to daily life.Therefore,many knowledge structures also exist in the form of cases that are closely related to human activities.Geographic simulation experiment is an effective method to assist geography learning.In 2017,the Ministry of Education issued the“Ordinary High School Geography Curriculum Standards” and proposed the concept of cultivating the core literacy of geography disciplines.Among them,one of the four major geography core literacy is geographical practice.Geographical simulation experiment is one of the main methods of geography learning.In the new curriculum standard,it is not only a method but also a goal.However,there are not many excellent simulation experiments in the actual classroom teaching of high school geography.Some of the deficiencies are that the experimental evaluation is not standardized.Therefore,the case study on the “Soil and Hydrology and Vegetation” simulation experiment of high school geography was conducted on the characteristics of the related knowledge of “soil,hydrology and vegetation” in the high school geography and related existing simulation experiments.The design and evaluation criteria study hopes to provide reference for the optimization design and simulated experimental evaluation of high school geographical "soil,hydrology and vegetation" simulation experiment cases.The research background and significance of the optimization design and evaluation criteria for high school geography “soil,hydrology and vegetation” simulation experiment cases are described.The current research status is analyzed and the results and deficiencies are summarized to further determine the optimal design and evaluation criteria for simulation experiments.The method and route lay thetheoretical foundation.Through the analysis of the textbook's knowledge about "soil,hydrology and vegetation",the specific optimization experiments were determined.Then,a large number of relevant cases and watching the relevant teacher's classroom records were analyzed to simulate the experimental cases and learn from each other.The optimal design idea of ??the simulation experiment is to take the student as the experimental subject,to take the experimental operability as the entry point,to draw on the research route of the science and technology experiment,to optimize the design of the simulation experiment case,and to summarize the optimization design method theoretically.Practice and reflect on the optimal design of the experiment,especially the inadequacies,in order to make the experimental case better.The construction process of the simulation evaluation criteria is mainly through the combination of interviews,curriculum requirements and physical,biological,and chemical disciplines related to experiments and evaluation criteria for the first-line teachers on high school geographical "soil,hydrology and vegetation" simulation experiment evaluation criteria.To establish the theoretical basis for experimental standards,to provide practical basis for the establishment of overall experimental standards,to specific experimental case design evaluation criteria,and to study the evaluation criteria for high school geography “soil,hydrology and vegetation” simulation experiments on the basis of theory and practice and standard case design.The main conclusions are as follows "Water and soil loss" and "Comprehensive development of watersheds-construction of dams" are specifically optimized for designing experimental cases and the two experiments are optimized,high school geography "soil,hydrology and vegetation" simulation experiment case optimization.The design should follow the principles of scientificity,openness,connection and operability of the elements,from the perspective of operability,efficiency,and ideology of the experiment,the case study of the “Soil,hydrology and vegetation” simulation experimentin high schools should be optimized.The geography “soil,hydrology and vegetation” simulation experiment case optimization design considerations are full preparation,the availability of experimental materials,the classroom nature of the experiment and focus on reflection and summary.The design of high school geographical "soil,hydrology and vegetation" simulation experiment evaluation criteria should follow the principles of scientificity,orientation,delamination,development and operability,the design of high school geography "soil,hydrology and vegetation" simulation experiment evaluation standards One of the major evaluation indicators is the geographic practice ethos of geography disciplines,with students as the object of evaluation,the content of the evaluation criteria is designed from the four dimensions of experimental operation,experimental methods,experimental harvest,and experimental attitude,and the rating of the evaluation criteria is divided into Four levels,from level 1 to level 4 to reach the highest level 4,implemented by means of teacher evaluation and student evaluation.Designing the "Water and Soil Loss" simulation experiment rating standard,"Comprehensive development of the basin-dam construction" simulation experiment evaluation Standards and high school geography "soil,hydrology and vegetation" simulation test evaluation criteria.
