Educational psychology helps teachers and school administrators address problems in teaching and learning that they were previously unable to solve due to inexperience, lack of psychological knowledge, and heavy workloads. It is the study of how social interactions and experiences influence a child's development and ability to learn. Educational psychology provides a scientific basis for understanding teaching and learning processes, handling individual differences, and ensuring students are ready and motivated to learn. It helps teachers decide what, when, how, and why to teach to best facilitate long-term retention of information.
