This document discusses the differences between basic research, applied research, and action research. Basic research aims to expand theoretical knowledge without considering immediate practical applications. It involves collecting and analyzing data to develop and enhance theories. Applied research seeks to solve practical problems and is usually conducted for industries or governments. It applies existing theoretical knowledge to address specific issues. Action research is a type of applied research that focuses on solving an immediate local problem through a cyclical process of planning, acting, observing, and reflecting.
