There are two sources of materials for undergraduate graduation design (thesis) creation: one is to obtain direct materials from social surveys and scientific experiments; The second is to obtain indirect materials from various documents. The materials obtained through literature review are mainly indirect materials.
One of the ways to obtain materials for literature review is to aim at mainstream literature, such as core journals, classic works, research reports, important viewpoints, and discussions related to this topic. It is a basic requirement to fully collect the relevant information of mainstream literature. For the requirements of undergraduate graduation project (thesis), the mainstream literature collected and read includes at least two foreign original documents. This method of collecting materials aims at solving where the materials for literature review come from.
Literature review the second way to obtain materials is to accumulate over time and sort them out at any time. For example, when studying at ordinary times, we should classify the documents, record the information of the documents and the places where books are collected. For particularly important documents, you should take reading notes and extract important opinions and arguments. In this way, by the time I started my graduation project (thesis), I had accumulated a lot of useful information. This method of collecting data aims at solving the problem of how to obtain literature review data.
The writing of literature review should embody the three basic characteristics of literature review: comprehensiveness, description and evaluation, so as to collect all the literature materials related to the subject as much as possible, analyze and summarize all the viewpoints as accurately as possible, and comment on the basis of objectively describing the viewpoints of various factions as much as possible, so as to express their own views and expound the development trend and trend of the subject. The main structure of literature review should include the review of research history, the comparison of research status quo and the development trend of research.
Generally speaking, the number of words in the main body of literature review that provides viewpoints and material basis for writing undergraduate graduation design (thesis) should be at least 2000 words. There are no less than 15 references and no less than 2 foreign documents. Literature review requires that references be listed at the end of the article, and the places cited in the article are marked with superscripts, which correspond to the serial numbers of listed references one by one.
