Research deals with the application of the scientific methods to problem solving. It has not always been evident to teachers and other educators that scientific methodology is of importance in education. Very likely this neglect of scientific methodology has occurred because research has been considered irrelevant to educators. Teachers have too many practical problems to worry about ivory tower research or so the belief goes. The book approaches research from a perspective different from that taken in other educational research text-books. The goal is to show educators that the application of research principles can make them more effective in their job of promoting learning. The basic point is that we do not have to stop teaching to do research; research is something we can do while teaching and if we do good research, we will do better teaching. This book includes most of the topics treated in traditional educational research books, but in a different order and with a different emphasis. The important content consists of using research ideas in a way that will promote effective teaching and learning in our Indian context. This book has been written for the use as a basic text-book for an introductory course of "Educational Research" or as reference for those interested in research and teaching research fundamentals. It includes twenty-three chapters in which concepts of research, education as discipline and hypothesis, sampling, historical, philosophical. Experimental research, methods, research tools, data collection, analysis or data, formulation of conclusions report writing, errors in conducting research, the development of educational research and priority fields of educational research. The author has been teaching educational research for last eight years to M.Ed., M.B.A. and guiding Ph.D. students. Students often expressed that there is no such comprehensive book in research of education, which can satisfy their needs. It was the encouragement of students of different disciplines and research scholars that led me to take up this work and the book "Research Methodology" is in your hands as a solution and future guidance in the field of research.
