I. Purpose and significance of the study
When writing an introduction, students should first clearly explain the purpose and significance of their research, that is, why they should write this paper, what specific problems this paper should solve, what effect it should achieve, and what reference or help it should provide to anyone or work.
For example, when writing an experimental paper, students can explain the instruments, equipment and experimental materials used, under what conditions, record the experimental results, and use what methods to analyze them, so as to achieve what results and provide reference or help for anyone or work.
When writing a design paper, students should explain where the design begins (generally from the current situation), investigate and study, analyze and consider various comprehensive factors and conditions, determine what kind of design scheme to achieve what kind of effect, and provide reference or help for who or work.
If you write a comprehensive survey paper, you should explain what the survey object is, analyze the existing problems and influencing factors, and then put forward some improvement measures or countermeasures to achieve what effect and provide reference or help for who or work.
Second, the research background
After explaining the purpose and significance of the research, students should also explain their research background in the introduction, such as what experiments, investigations, research or designs have been done by predecessors in this field, and what work has been done, and what inspiration does it have for this research? What research gaps does this paper fill? What are the related researches at home and abroad? The predecessors have not investigated and studied it, which means that a novel and meaningful topic in the research field has been ignored by the predecessors; There has been research or discussion before, but the discussion and demonstration are not comprehensive enough (or no one in the student area has done it), so students' papers should be enriched, developed or supplemented, or their views should be refuted.
Third, the main contents and methods of the study
In the process of thesis writing, the research methods used by students should also be explained in the introduction. Literature review is a method used in all kinds of papers, and writing academic papers is inseparable from consulting various materials, academic documents and monographs. According to the different types of papers, students will also use other research methods in the process of writing papers, such as investigation and analysis, statistics, field visits, typical case analysis, questionnaires and so on.
In the introduction, students should also summarize the main contents of the paper. For example, the main contents of experimental papers usually include experimental materials and methods, result analysis, conclusions and so on. The main contents of design papers usually include current situation analysis, design scheme, specific design instructions, drawings and conclusions, and the main contents of comprehensive investigation papers include current situation investigation, analysis of existing problems, analysis of influencing factors, countermeasures and suggestions, conclusions, etc.
