The basic idea of factor education theory is that the education process should start with the simplest "factors" that some children can accept, and then gradually turn to more and more complex factors.
Pestalozzi's theory of factor education is rooted in his acceptance that Rousseau's education should adapt to natural thought. He believes that children are born with the ability and strength to demand developmental tendencies. Education should adapt to children's nature and follow the natural development order of children's natural ability and strength. The development of children's ability is from simple to complex. For example, people's understanding begins with feelings. By observing the outside world, they gradually form clear beliefs and turn to thinking, and all kinds of feelings are based on simple elements. When you fully understand the simple elements, the most complicated feelings and impressions will become simple and clear. Education should start with the simplest elements and gradually turn to more complex aspects. For example, the simplest element of exercise is various joint activities; The simplest element of moral education is children's love for their mothers; The simplest elements of intellectual education are numbers, shapes, words and so on.
