Choosing a topic is the first step in writing a thesis. A journey of a thousand miles begins with a single step, and topic selection is very important for paper writing. It not only determines the main direction and goal of thesis writing, but also stipulates the methods and approaches of thesis research to a certain extent. At the same time, it is also an important factor to measure a researcher's research ability and thesis writing ability.

◆ The importance of the topic selection of the paper

As the saying goes, "a good paper is half the battle", that is, choosing the right research topic is equal to half the battle in writing the paper. The topic selection of academic papers is largely restricted by the choice of research topics. There are many factors that determine the quality and value of academic papers. But the topic selection plays a decisive role. Only choose the right theme. It is valuable and meaningful to collect materials, understand materials, refine specific viewpoints and write research results. On the contrary, it is worthless even if it takes a lot of energy.

◆ The main problems existing in the topic selection of middle school students' papers

In the process of middle school students' project research, many students are confused about the topic selection due to the limitation of cognitive ability and academic accomplishment. There are many problems in the process of topic selection, among which the most important, easy-to-commit and serious problem is that the topic selection is too big and vague, such as "X-ray Double Star Research", "Cycling Research", "The Artistic Essence of Hegel's Music Philosophy" and "Extracurricular Classes for Primary and Secondary School Students". This is very difficult for a middle school student. Unless the author has accumulated profound academic knowledge in related fields for many years, discussing these issues in about 10,000 words will inevitably lead to empty and pale content, with nothing to say, mostly the induction of some common-sense theories and knowledge, and lack of basic academic innovation. Regardless of whether the author has the ability to master these grand topics, from the operational level alone, too large a discussion field will often put forward higher requirements for the author's knowledge reserve, data collection, argument enrichment, etc., which will invisibly increase the writing difficulty for middle school students.
