Observation method refers to a method in which researchers use their own senses and auxiliary tools to directly observe the research object according to a certain research purpose, research outline or observation table, so as to obtain information. Scientific observation is purposeful, planned, systematic and repeatable. In scientific experiments and investigations, observation has the following functions: ① Expanding people's perceptual knowledge. 2 inspire people's thinking. (3) lead to new discoveries.

How to present the observation method of graduation theory in the paper

First, the basic concept of observation method

Observation is that scientific research objects make corresponding plans according to the researcher's research purpose, and systematically inspect objective things through sensory organs and auxiliary equipment, so as to obtain effective information.

Second, the characteristics of observation method

1. purposeful

According to the needs of the research topic, to carry out research to solve a certain problem has a clear research purpose and research object.

2. Objectivity

3. Initiative

Make plans and make changes in case of unexpected situations in the process.

Third, the role of observation method

For example, in the research of animal husbandry, observation is the most intuitive and commonly used method.

Observation is the most basic method to collect raw data, such as estrus identification of sows.

The mating time is determined by observing the behavioral characteristics of estrus sows.

According to different standards, observation methods can be divided into structural observation and unstructured observation, direct observation and indirect observation, natural observation and laboratory observation, key observation and comprehensive observation. Any observation method is different, and the author needs to make specific observation according to the research object.
