1. Questionnaire survey method: Questionnaire survey method is a commonly used research method, which is mainly suitable for the collection and analysis of large-scale data. Through the questionnaire survey, we can understand the attitudes, opinions and behaviors of the respondents, thus providing data support for the research.
2. Experimental method: The experimental method is to explore the causal relationship by comparing the differences between the experimental group and the control group. This experimental method can accurately control variables, so as to get accurate experimental results, but the experimental process needs a lot of time and energy.
3. Case study method: Case study method is a research method through in-depth analysis of specific cases. Case study method can deeply understand the situation and background of the research object, but due to the small number of samples, the universality and representativeness of the results may be poor.
4. Literature review method: Literature review method is a method to study problems in a certain field through systematic analysis and synthesis of existing literature. Literature review method can quickly understand the present situation and trend of research field, but it needs high literature retrieval and screening ability.
5. Observation method: Observation method is a method to conduct research by observing and recording the behaviors and phenomena of the research object. Observation can deeply understand the behavior and reaction of the research object, but the observation result may be influenced by the subjective factors of the observer.
To sum up, the design methods of this paper include questionnaire survey, experiment, case study, literature review and observation, and researchers should choose appropriate methods according to the research purpose and specific situation.
