Linear and non-linear learning
Thursday, December 13th, 2007
Obligatory pic of horrific looking 19th cen school that should add impact to the post.
In a previous post, I talked about what language learning 2.0 meant to me. In the coming weeks and months I’ll try to elaborate through examples from projects that I’ve been involved with. I begin with a description of a key concept in learning 2.0 - its non-linear nature. I’ll try to outline my thoughts on this before showing how it has affected the design of ChinesePod and SpanishPod in the next post.
Linear learning
Textbooks, curricula, and our educational system itself are the products of a mechanistic past. School knowledge is pre-determined by a centralized authority, and delivered in a linear format to a mass audience. The system is standardized, mass produced, scheduled, etc. In the classroom, the emphasis has been on teaching - it is expected that the learning will simply follow. The act of teaching, then, is seen as transfering information in a controlled sequence, a process that eliminates context - all learners receive the same content in the same format - but fails to accommodate variations in learner needs.
At the individual level, traditional learning is also ‘linear’. Most textbooks stagger information - you can’t proceed to Unit 2 until you’ve learned Unit 1, type of thing. Let me give you an example: English languge textbooks for decades, have begun with present tense (aspect) verbs with an emphasis on the 3rd person. It’s always the first lesson. Thereafter the books invariably proceed with simple past tense, then past continuous, and so on. In fact, however, most learners of English do not ‘acquire’ the earliest items until they reach an advanced stage of fluency. It’s obvious that these sequence of items are presented out of expediency. The question is, however, whose expediency - the teachers’ or the students’? (There is no natural order of language learning that can be described as a linear set of morphemes.)
Non-linear learning
In nature, linear learning doesn’t exist. Children learn their mother tongue through random exposure and make sense of the language by identifying patterns. Our brains are designed to work/learn this way, but it is a subjective process because each individual experiences distinct social and psychological phenomena.
If there is a metpaphor for learning in the natural environment it may be the network rather than the line: our neural networks forms the basis of memory/knowledge and even the brain itself. Which is interesting because all networks come down to two elements: links and nodes. (This is as true for the internet as it is for the human brain.)
The internet is changing the way we learn and that’s because of its network qualities. I believe we’ve moved beyond the Mechanical Age, and beyond the Information Age, to the Age of Networks, and therefore to the Age of Networked Learning. Networks are every where and, as Jay Cross persuasively argues, they are changing everything, including how we learn. The last time that happened we had the Enlightenment on our hands.
In the next post I’ll try to show how we’ve applied these insights in the real life design of our learning programs. In the meantime, feel free!
