### Test and Effect Evaluation
#### 4.4.3 Test Results Before and After the Course  
1. Knowledge mastery. In the test of wetland ecosystems and migratory bird habitats, at the beginning of the course, the average score of students was about 60 points, the correct rate of multiple-choice questions was about 60%, the answers to short-answer questions were relatively brief, and the analytical questions generally lacked depth. As the course progressed, after multiple knowledge tests and learning activities, the average score in the middle of the course increased to about 75 points, the correct rate of multiple-choice questions increased to 80%, the short-answer questions were able to explain the principles in more detail, and the analytical questions began to be analyzed in depth with actual cases. At the end of the course, the average score reached more than 85 points, the correct rate of multiple-choice questions stabilized at more than 90%, the answers to short-answer questions were accurate and in-depth, and the analytical questions were able to comprehensively and deeply analyze the complex relationship between wetland ecological changes and migratory bird habitat changes. In the group discussion and report on the knowledge of forest ecosystems and the impact of human activities, at the beginning of the course, students had low participation, superficial views, and an insufficient ability to integrate and apply knowledge, with an average score of about 65 points. After a series of learning and practical activities, the students' participation in the course was significantly improved in the middle of the course. They were able to put forward some valuable ideas, and their ability to integrate and apply knowledge was enhanced. The average score increased to about 80 points. At the end of the course, the students were active in the discussion, able to deeply analyze the relationship between forest ecosystems and human activities, and could use the knowledge they learned to put forward reasonable protection and development suggestions, with an average score of more than 90 points. 2. Practical operation ability. In the practice of data collection and processing ability, at the beginning of the course, students had major problems in the accuracy of data collection, such as large errors in the statistical number of migratory birds and inaccurate soil moisture measurements. Data processing was also relatively unfamiliar, and the average score was only about 50 points. With the increase in the number of practices and the real-time guidance of ERNIE Bot, the accuracy of the students' data collection increased to more than 80% in the middle of the course, and they were able to skillfully use tools for data processing, with an average score of about 75 points. At the end of the course, the accuracy of the students' data collection reached more than 95%, and they were able to efficiently and accurately complete data processing and analysis, with an average score of more than 90 points. In the practice of simulating ecological models and predictive ability, at the beginning of the course, the models constructed by students had many scientific problems, the prediction results were unreasonable, and the average score was about 45 points. With the deepening of learning and the proficiency of the ERNIE Bot simulation tool,
