1. In-depth understanding of the research field: In the research process of this paper, I have a deeper understanding of the selected research field. Through reading relevant literature and field investigation, it is found that the original topic has produced many research results in this field, and it is difficult to make new breakthroughs and innovative contributions. I decided to change the topic of my thesis and choose a direction with more research value and innovation.
2. Feasibility consideration of practical research: Before the preliminary practical research, I made further feasibility consideration on the topic of the original paper. Through discussions with tutors and experts, I realized that the original subject faced some technical, data acquisition or resource constraints in actual research, which led to research difficulties or inaccurate and unreliable results. In order to ensure the feasibility and effectiveness of the research, I decided to change the title of the paper and choose a research direction that is more in line with the actual conditions and resources.
3. Adjustment and optimization of research objectives: After preliminary research, I further thought and analyzed the title of the original paper. Through the communication and discussion with fellow scholars, I realized that the original topic had some vague or unclear definitions of research objectives and problems, and it was difficult to accurately measure the research results and values. In order to better clarify the research objectives and problems, I decided to change the title of my thesis and choose a more specific, clear and quantifiable research direction.
