Educational psychology assists teachers in selecting an effective learning theory and developing a strategy based on it that takes into account the individual characteristics of their students, significantly increasing the effectiveness of learning. Theoretical developments of the ideas of programmed learning, problem-based learning, developmental learning, and so on enable teachers to select the most productive method of teaching their students based on their subject, a specific class, or a specific topic of the lesson. Knowledge of educational psychology, which employs neuropsychology and cognitive sciences, assists the teacher in developing an effective teaching strategy. Empirical, cognitive, and neuropsychological studies, for example, show that training in the form of productive struggle is more effective.
