Applicability of the Natural Experimental Research Method in Educational Psychology to Research

The experimental method is a controlled observation. According to a certain research purpose, the researcher formulates a careful design in advance, controls the factors unrelated to the research, and allows the researcher to trigger a certain behavior under certain conditions, so as to study the causal relationship between a certain condition and a certain behavior. In psychology, the investigator of the experiment is usually referred to as the subject, and the person being studied is called the subject.

The experimental method is a rigorous and objective research method, which occupies an important position in psychology. Experimental methods can be divided into two types: laboratory experiments and natural experiments.

a) Laboratory experiments.

Laboratory experiments are controlled observations made using instruments and equipment in a psychological laboratory and in a rotational laboratory. It provides precise experimental results and is commonly used to study perception, memory, thinking, movement, and physiological mechanisms.

2. and calendar) natural experiments.

Nature experiments are controlled observations in the subject's original environment. For example, under the condition that classroom teaching does not affect classroom teaching, the effect of teachers' intonation on the attention of primary school students is studied. Studying the mutual aid behavior of elementary school children in physical activity on the sports field, etc.

Psychology is a highly empirical science. The characteristics and laws of the psychology of the subjects can only be analyzed and synthesized from the actual materials collected, and cannot be taken for granted by the researchers. Therefore, everyone who studies psychology must learn to use research methods correctly.

Psychological phenomena are complex, and which method to use should be determined according to the research object, research conditions, and research purpose, and sometimes it is necessary to combine several methods to collect multifaceted data.

The various research methods of psychology are direct hand-rented tent passages that collect perceptual materials, with the aim of analyzing and deducing regularities from them. Therefore, every person who studies psychology must also apply materialist dialectics to make a comprehensive, profound, and interrelated rational analysis of perceptual materials, so as to prevent one-sided, isolated, and static research on psychological phenomena.

Limitations of Educational Experiments.

Educational experiments require researchers to provide theoretical hypotheses, actively intervene in research objects, strive to control irrelevant variables, accurately determine dependent variables, scientifically summarize experimental results, etc., all of which put forward high requirements for the quality and ability of researchers, prompting them to study seriously, study hard, improve experimental techniques, and give full play to their subjective initiative.

On the other hand, the success of the experiment will prompt researchers to increase their enthusiasm for engaging in educational reform experiments, forming a virtuous circle.

First, many phenomena and problems in the field of education often contain many variables and complex interrelationships, and in a certain educational situation, only experimental methods may not be able to solve the problems, and must be combined with investigation methods and theoretical research methods to truly reveal the law of educational development.

Second, the object of educational research is people. During the experiment, it is easy to interact with the researcher and the subject. For example, the psychological reaction of teachers and students to experiments, etc.; Moreover, the researcher's own opinions, attitudes, and motivations will also affect the direction of the experiment. These can affect the results of the experiment.

Thirdly, under the existing measurement tools and experimental conditions, it is difficult to completely avoid the sampling error of the subject and the measurement error of the dependent variable. The sample size of the experiment is small, and the conclusions generalized to the subject population lack credibility.

Answer] The :d observation method is a method for teachers to observe, record and evaluate the phenomena or behaviors to be studied in a purposeful and planned manner under the conditions of natural calm.

1. Transversal research: less time-consuming, labor-saving, and large amount of information; However, it is a related study, less causal 2 Longitudinal study: strong control, causal research can be carried out, which is helpful to obtain detailed effects; But time-consuming, labor-intensive 3 aggregate crossover studies:

It combines the advantages of both horizontal and longitudinal orientation. 4 The advantages and disadvantages of various specific research methods are: (1) Interview method and observation method

Less control, less volume, more material analysis; (2) Case method: research with long time and meticulous research, which is conducive to the discovery and development process of causality (3) Questionnaire and measurement method: can be used for horizontal research, can also be used vertically, and can be used for large-scale research (4) Cross-cultural research

It is conducive to the construction of commonality and individuality of cultural level, and to the study of the relationship between human psychology and culture.

Practice is the only criterion for testing truth.

A controlled experiment is an experiment in which the conditions are the same except for the different conditions, and this different condition is the only variable Set up a set of control experiments to make the experimental results convincing The general treatment of experimental variables is the experimental group If there is no treatment, it is the control group

So the answer is: all other things being equal.

Answer] The :d observation method is a research method in which teachers observe, feast, record, and evaluate the phenomena or behaviors to be studied in a purposeful and planned manner under natural conditions. Mishi.
