Research is "creative and systematic work undertaken to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." or in other hand Research is a process of steps used to collect and analyze information to increase our understanding of a topic or issue. At a general level, research consists of three steps: 1. Pose a question. 2. Collect data to answer the question. 3. Present an answer to the question. This should be a familiar process. You engage in solving problems every day and you start with a question, collect some information, and then form an answer Research is important for three reasons.1. Research adds to our knowledge: Adding to knowledge means that educators undertake research to contribute to existing information about issues 2.Research improves practice: Research is also important because it suggests improvements for practice. Armed with research results, teachers and other educators become more effective professionals. 3. Research informs policy debates: research also provides information to policy makers when they research and debate educational topics. A research project may also be an expansion on past work in the field. Research projects can be used to develop further knowledge on a topic, or in the example of a school research project, they can be used to further a student's research prowess to prepare them for future jobs or reports. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological, etc. The scientific study of research practices is known as meta-research.
