The correct answer is: Action research.
Action research is a type of research that aims to solve practical problems in real-world settings. It is a cyclical process that involves identifying a problem, planning and implementing a solution, evaluating the results, and taking action based on the findings. Action research is often used in education, social work, and other fields where there is a need to improve practice.
Empirical research is a type of research that is based on observation and measurement. It is used to gather data about the world and to test hypotheses. Empirical research can be quantitative or qualitative. Quantitative research involves collecting data in the form of numbers, while qualitative research involves collecting data in the form of words or images.
Conceptual research is a type of research that is concerned with developing and refining concepts. It is often used in the humanities and social sciences. Conceptual research can be theoretical or empirical. Theoretical research involves developing new concepts or theories, while empirical research involves testing existing concepts or theories.
Fundamental research is a type of research that is aimed at expanding knowledge for its own sake. It is often conducted in universities and research institutes. Fundamental research can be theoretical or empirical. Theoretical research involves developing new theories, while empirical research involves testing existing theories.
Action research is the type of research that aims at immediate application because it is a cyclical process that involves identifying a problem, planning and implementing a solution, evaluating the results, and taking action based on the findings. This makes it well-suited for solving practical problems in real-world settings.
