Inquiry learning.

"Inquiry is not activities predetermined by the teacher linked by a predetermined focus, topic or theme. It is a collaborative process in which both students and teachers work together, often, to negotiate aspects of the curriculum. Inquiry learning encourages learners to examine the complexity of their world, to explore how it works and their place in it as they form their own understandings instead of being told simple answers to complex problems. It recognizes that students are powerful learners who must be actively engaged in the process of investigating, processing, organizing, synthesizing, refining, extending and applying their knowledge."
