This is what George Siemens writes about the science and art of learning:
It's important to understand and measure ... the impact of training and learning. Unfortunately the scientists of learning have the dominant voice in the learning space. The artists are not being heard.
The scientist's role is one of determining best approaches to knowledge discovery, creation and dissemination .... What is the role of the artist in the learning space?
The artist is the individual who sees the magic in learning. They may not know exactly why something worked well, but can see that the learners are changing, growing and developing ... the artist sees the beauty of uncertainty and values learning as both a process and a product.
We need the voices of both the scientist and the artist Nether one is necessarily better than the other. Both, held in balance and for appropriate task, are needed for learning and knowledge sharing.
