One may be able to identify research problems from the following sources:
Reading: Relevant questions may come to mind as we critically examine books and articles on the subject of our interest. When we read study reports, similar research areas could come to mind.
Teaching And learning materials: Many interesting problems to study will be suggested through classroom lectures, class debates, seminar discussions, and outside-of-class exchanges of ideas with classmates and lecturers.
Everyday Life: Life has motion. Every day brings new experiences and new learning. If we are all perceptive and curious about the same issue, we can come upon some intriguing questions. This is demonstrated by the tale of Newton. Before Newton, apples had landed on the beads of other people. However, it was only sensitive Newton who posed the query regarding the apple fall that resulted in the discovery of the Law of Gravitation.
Suggestion: Identification of important research problems will be aided by consultation with experts, researchers, etc.
Field situation: Exposure to issues that demand investigation is provided by field trips, training, and extension activities.
Brainstorm: An intense conversation among a group of interested people can frequently lead to the development of fresh perspectives on a topic and the identification of significant questions.
Thinking: The reflecting mind is a wellspring of knowledge, and new ideas can occasionally come to one's head in a flash.
