The general procedure of educational experiment usually includes the following stages:
Determine the research question: Before starting any experiment, you must make clear what the research question is. This can help researchers determine the type of data needed, experimental design, participants and how to analyze the data.
Literature review: refer to relevant research literature to find out which studies have discussed related issues, thus helping to determine the uniqueness and novelty of the research. At the same time, we can understand the existing research results and theories, and provide theoretical basis for experimental design.
Making experimental design: according to the research questions and the results of literature review, determine the independent and dependent variables of the experiment and choose the appropriate experimental design. The experimental design should be able to answer the research questions and ensure the internal validity and external validity of the experiment.
Selection of experimental subjects: determine the subjects needed for the experiment to ensure that they meet the experimental requirements. This may require recruiting students, teachers, schools or other educational institutions as experimental subjects.
Experiment: During the experiment, it is necessary to properly intervene or operate the subjects and collect the required data. These data may include students' grades, participation and satisfaction.
Analyze data: Use appropriate statistical analysis methods to process and analyze the collected data to answer research questions. This may involve descriptive statistics, regression analysis, analysis of variance, etc.
Writing a research report: Write a research report according to the experimental results, including research objectives, methods, results and conclusions. The report should clearly, accurately and objectively describe the experimental process and results, and explain and discuss the results.
Evaluation and reflection: evaluate the experimental results to determine the effectiveness and reliability of the experiment. If there are shortcomings, we need to reflect and improve them in order to better solve the problems in future research.
In a word, the general procedure of educational experiment is a systematic process, which requires researchers to have strict scientific research attitude and methodological knowledge. Through the experiment according to this procedure, we can better explore the problems in the field of education and provide scientific basis for improving educational practice.
