The Research On The Validity Of Research Methods In The Field Of Library And Information Science

Validity is first put forward in the field of surveying to verify that measuring tools can accurately measure the degree of things being tested.Method as a tool for research,its scientific nature is an important means to ensure the orderly conduct of research,a scientific study of whether the validity of the method selected by the research should be reflected by the validity.At present,as an important research type in the field of library and information science,more and more scholars choose empirical methods to conduct research.The validity of the research method proposed in this study is actually the validity of the empirical research method.The validity of the method selected in the empirical research can ensure the scientific nature of the research results.At present,in the field of library and information science,many researchers apply validity theory to statistical analysis,and use some software to test the validity of questionnaire,scale and other measuring tools used in the research.However,this method is not suitable for all validity tests.Questionnaires and scales that can carry out validity tests also need to meet certain conditions,and the validity of research methods cannot be tested.This study considers that the validity of the research method is not enough to be tested by statistical analysis software or expert evaluation,but by the logic of the implementation process of the research method.To embody.The full text is divided into five chapters.The first chapter is the introduction,which introduces the background,the research status and the significance of the research.The second chapter combs the development of the titer theory,introduces its development stage and test type,and introduces the research logic.It is pointed out that the validity of the research method can not be tested,but should be reflected by the research logic.The third chapter analyzes the documents published by the authoritative journal "Journal of Library Science in China" in the past five years,and introduces the current research situation of the validity of relevant research methods in the field of library and information science.The fourth chapter starts with the research logic,and points out that the validity of the research method can be improved through four aspects: Reliability is the basis of validity,the reliability of the investigation data should be guaranteed.The theoretical hypothesis is the premise to guarantee the validity of the research method,so it is necessary to put forward the theoretical hypothesis scientifically.The logic of operation is the key to guarantee validity.In the process of operation,we should follow the logic.Firstly,we define the related concepts in the theoretical hypothesis.It is also very important to select the typical survey object in the typical research and the representative sample in the sampling study.The fifth chapter summarizes the above,and points out that the commonly used validity test method is to test the validity of the tools selected in the empirical research,but not to the validity of the research method.In the process of empirical research,researchers are urged to pay attention to the logic of research and ensure the validity of the research.
