There are several key factors that can affect learning: 1) Factors related to the learner themselves, including their physical and mental abilities, potential, health, interests, attitudes, intelligence, prior knowledge, and motivation. 2) Factors related to the teacher, such as their mastery of the subject matter, teaching skills, ability to understand learners, teaching approaches, content selection, organization, linking new concepts to old, balancing theory and practice, providing feedback, and transferring learning. 3) Environmental and working conditions that can impact learning, like the physical environment, socio-emotional climate, facilities, class size, noise levels, schedules, staff coordination, and basic resources.
