The table below illustrates how different established pedagogies tend to lead to different kinds of learning experiences. Combining pedagogies which share common practices can help reduce the trade-offs of using too many pedagogies. For example, in a school where students are practiced in inquiry-based learning, teachers might feel more confident in combining his approach with challenges or complex projects, knowing that students are competent at managing their own learning. Studying common combinations of pedagogies can help to identity those practices which are common to several pedagogies, such as presentations of learning, or student self-assessment.
