Different pedagogies are based on different theories of learning and what is regarded as most important; the full power of a pedagogy - and of pedagogical innovation - can only be evaluated in taking into account all the things the pedagogies are trying to achieve. The way that people are taught affects how and what students leam. Particular pedagogical approaches have been developed and refined to promote a variety of different kinds of learning: for example, learning of explicit content, learning of particular ways of doing things, or the learning of values and habits.
