The book highlights the educational process, which opens up new perspective and warrants the adoption of new strategies for achieving better research. The traditional approaches focused mainly content and methodology from a teacher- centered point of view, ignoring crucial student factors which profoundly affect his performance. Teachers and educational authorities were dismayed and puzzled to find students performing poorly in spite of good methods and content. This led to the search and study of other factors that influence the student's learning and performance and a lot of research work was undertaken in this direction.
