Then this research explained an ideal experimental research method and a realistic experimental research method, focusing on an experimental research method. This might provide realistic research guidelines for researchers in the area of literacy education research who have been interested in an experimental research method. Through this paper, the investigator would like to help them become independent literacy researchers.
