Research is a way of gaining knowledge and finding solutions. It involves empirical investigation and corrects mistakes by experts. Research provides background information when experience or intuition may be limited. The main purposes of research are to agree with others, prove opinions, and apply the scientific method to solve problems. Research in education aims to expand knowledge and solve educational issues. The basic types of research are basic research, which adds to existing knowledge, and applied research, which provides practical solutions. Research can be qualitative, which studies topics holistically, or quantitative, which uses numerical data and focuses on a few variables. Good research questions are significant, feasible, clear, investigate relationships, and ethical.
