How a person learns is not just a matter of what happens inside their head. The brain's own workings are shaped by culture, by the people around them, by how they are taught, and by their stage of life. A full picture of learning has to connect what goes on inside the learner with these outside forces.
Whether and how well someone learns depends on their motivation, not only on their ability or the quality of the material. Motivation is one of the core influences on learning, alongside the mental processes involved.
Educational technology works better when it is designed around what is known about how people learn. It also has to be adapted to the particular place and people using it, rather than dropped unchanged into any setting.
People from different cultural and social backgrounds can learn in different ways. These differences are a real influence on learning, not noise to be averaged away, so one way of teaching should not be assumed to suit every group.
Learning is not finished in childhood or confined to school. The brain keeps adapting from birth through old age, and people learn in workplaces and everyday life as well as in classrooms. What helps someone learn can change as they age.
