An editorial in the April 2010 edition of Nature Magazine raises some important issues about student learning experiences in the sciences. [The] "evidence strongly suggests that most of what the general public knows about science is picked up outside school, through things such as television programmes, websites, magazine articles, visits to zoos and museums — and even through hobbies such as gardening and birdwatching. This process of 'informal science education' is patchy, ad hoc and at the mercy of individual whim, all of which makes it much more difficult to measure than formal instruction. But it is also pervasive, cumulative and often much more effective at getting people excited about science — and an individual's realization that he or she can work things out unaided promotes a profoundly motivating sense of empowerment." (Nature 464, 813-814)

The same argument can be made for many other disciplines. The relationship between informal and formal learning is characterized by extreme fuzziness. As I have discussed in recent articles (particularly, The Radical Impossibility of Teaching) classrooms and formal lectures may well be the last place in which empowered and empowering learning takes place. The formal schedules of schools, departments divided into sometimes highly contested disciplines, and the credit system all discourage the value and importance of informal learning.

In fact, learning informally is at the heart of how people discover new things and new ways of understanding the world. For example, a visit to a museum combines the experiences of viewing with the challenges of interpretation. It would be difficult to summarize or quantify the relationships that viewers developed with Mark Rothko's work at a recent retrospective at the Tate Modern in London. Something was happening, although it was difficult to know what. Many visitors sat and stared at the paintings for quite a while. Were they wasting time? Or were they exploring the canvases, their brilliant colours and careful shading?

"An Ad Hoc Committee of the National Association of Research in Science Teaching
(NARST) stated in 2003 that there are three “important characteristics of learning… First, learning is a personal process, second, it is contextualized, and third, it takes time…Learning occurs when people reconstruct meaning and understanding; a different way of thinking, perhaps, or a different way of responding to an idea or event. Learning that occurs today depends on yesterday’s learning and is the foundation for tomorrow’s learning. The cumulative, iterative process of learning emphasizes the importance of time.”. Our own research in this area reinforces the importance of iteration." (Susan Stocklmayer, Public awareness of science and informal learning - a perspective on the role of science museums, published by the National Academies in the US)

Learning takes time and follows many pathways. A good teacher can create a map with destinations, but the routes have to be developed by the students. Those routes may meander for a while because the iterative process is not the same for everyone. Knowledge and information can be shared along the way. Wisdoms can be imparted through discussion and interaction, but these travels will always be characterized by the richness of the unexpected sometimes colliding with the expectations of teachers and other times producing engaged and engaging dialogue.

The tyranny of schedules in schools is that they artificially 'locate' learning at a time and place that may not be convenient for everyone. The schedule cannot account for iterative processes because it generates a linear type of learning that goes against its very essence.

"To summarize: learning rarely, if ever, occurs and develops from a single experience. It is cumulative, emerging through diverse experiences. It is a dynamic, never-ending, and holistic phenomenon of constructing personal meaning. Much of what people come to know about the world, including the world of science content and process, derives from real world experiences within a diversity of appropriate physical and social contexts, motivated by an intrinsic desire to learn."
