The document discusses defining a research problem through several key points:
1) A research problem identifies an area that needs further investigation to address a gap in knowledge or understanding. It questions an issue but does not propose a solution.
2) Sources for identifying problems include a researcher's field of study, social and economic trends, existing programs/initiatives, observations, and literature.
3) In selecting a problem, considerations include the topic's uniqueness, significance, researcher's expertise and interest, available resources and data, and ethics. A well-defined research problem is important to successfully conduct meaningful research.
