Investigation method:

Investigation is one of the most commonly used methods in scientific research. It is a purposeful, planned and systematic collection of original data related to the actual situation or historical situation of scientific research objectives. Investigation is a common basic research method in scientific research, which flexibly uses historical time method.

Through observation, conversation, questionnaire survey, case study, testing and other scientific research methods, we can master the cultural and educational situation in a planned, detailed and systematic way, and analyze, synthesize, compare and sort out many materials collected from the investigation, so as to show you staged professional knowledge.

Observation method

Observation is a way for academic research to observe the research object in real time with its own senses and auxiliary software according to a certain research purpose, research outline or observation table, and then obtain materials. Scientific observation is utilitarian, purposeful, targeted and accurate. In scientific experiments and investigation reports, observation has the following functions:

(1) Expand your perceptual knowledge.

② Enlighten everyone's logical thinking.

(3) There are new discoveries

experimental method

Experimental method is a scientific research method to discover and determine the causal relationship between things according to the transformation of main branches and the manipulation of scientific research objectives.

Its main features are:

First, active and transformative observation and investigation are all about understanding scientific research objectives and finding problems without interfering with them, while experiments stipulate the necessity of actively controlling inspection standards, artificially changing the existing mode of objectives and transforming the whole process to make them obey scientific understanding.

Secondly, according to the needs of scientific research, the zoning planning of scientific experiments relies on various technical means to reduce or eliminate the influence of various irrelevant factors that will harm scientific research, and to understand the scientific research objectives in a simplified and purified way.

Thirdly, causality test is a reasonable and special tool and necessary way to find and determine causality between things.
