First of all, a common misunderstanding is that the topic is too broad or too narrow. Too broad a topic will make the research content too scattered and it is difficult to draw specific conclusions; However, too narrow a topic may limit the depth and breadth of research. The way to solve this problem is to conduct sufficient background research and literature review before selecting the topic, understand the research status and unresolved problems in this field, and then choose a suitable topic.

Secondly, another common misunderstanding in the process of topic selection is that the feasibility and importance of topic selection are not fully evaluated. Sometimes, graduate students may be attracted by some novel or popular topics, but whether these topics have enough resources and conditions for in-depth research has not been considered. The solution to this problem is to make a detailed feasibility analysis of the selected topic, taking into account the requirements of time, funds, experimental equipment, data and so on.

In addition, there is a common misunderstanding, which is to choose a topic that is too difficult or too simple. It is too difficult to choose a topic, which may lead to slow research progress and even no effective results; But if the topic is too simple, it may lack innovation and academic value. The way to solve this problem is to reasonably evaluate the difficulty of selecting the topic according to your own research ability and time limit, so as to ensure that the topic has certain research challenges and academic contributions.

In addition, there is a common misunderstanding that there is no sufficient discussion and communication with the tutor. Tutors are important instructors and participants in the process of selecting topics for graduate thesis, and their opinions and suggestions on topic selection are very valuable. The solution to this problem is to discuss with the tutor regularly, report the research progress, and accept the tutor's criticism and suggestions.
