Constructivism is growing on me
Here is a good definition of my new favorite (Not) learning theory - Constructivism:

There are many different schools of thought within constructivist theory, all fall within the same basic assumption about learning. The emphasis is placed on the learner or the participant rather than the teacher or the instructor. It is the learner who interacts with objects and events and thereby gains an understanding of the features held by such objects or events. The learner, therefore, constructs his/her own conceptualizations and solutions to problems. Learner autonomy and initiative is accepted and encouraged.

Constructivists view learning as the result of mental construction. Participants learn by fitting new information together with what they already know. People learn best when they actively construct their own understanding. In constructivist thinking, learning is also affected by the context and the beliefs and attitudes of the learner. Learners are encouraged to invent their own solutions and to try out ideas and hypotheses. They are given the opportunity to build on prior knowledge.

Cognitive experiences situated in authentic activities such as project-based learning, cognitive apprenticeships, or case-based learning environments result in richer and more meaningful learning experiences. Social negotiation of knowledge allows a process by which learners form and test their constructs in a dialogue with other individuals and with the larger society. Collaboration becomes a principal focus of learning activities so that negotiation and testing of knowledge can occur.
