I’ve been fortunate to work in the three great cities of the East Midlands – Leicester, Nottingham and Derby. My first 29 years of life were spent in Leicester. As a result of hundreds of trips to family and friends, I was able to develop an extensive knowledge of the area. Despite no longer living there, I often visit, and when traffic is bad I benefit from knowing most of the rat runs to ensure a timely arrival at my destination. Having this knowledge means that I can be creative with the journey I take. I can make sound judgements about where the traffic is likely to be bad and where I can save time by going alternative routes.
After much of my life in Leicester, I spent 3 years working in Nottingham in a role which required a lot of travel around the city. During this time, I developed a reasonably good knowledge of the city, getting to grips with most areas. Today I visited an area of Nottingham that I hadn’t previously, so as I neared my destination I needed to switch the sat nav on to guide me in. As I left the area to go to another part of the city, I started to recognise where I was and so the sat nav could be put away. Some knowledge of the area meant that I didn’t need to rely on the sat nav for too long.
I’ve been working in Derby for the last few months and prior to that, had only visited on a few occasions. Much like my previous role, my current position involves a lot of travel. Today I made it out of Derby to Nottingham and back to Derby without my sat nav – the first time I have managed such a feat! Usually I am reliant on my sat nav to direct me everywhere in Derby.
On my travels, I started to think about learning, specifically knowledge of new areas. You see, when I drive around a new city, I use my sat nav as it tells me exactly where to go and on most occasions, I get to my destination in the most time efficient manner. Were I to try getting to a destination without the sat nav, I’d lose much of my day trying to figure out where I needed to go. Until I have developed a sufficient knowledge base which allows me to recognise that I’m on the correct route, the sat nav is my guide. Once I have a wealth of knowledge, the sat nav becomes redundant.
This is analogous to learning. Teacher = sat nav. If we want to learn anything, it is far more efficient and effective to be told by the teacher in the first instance. It is no good trying to figure out things for ourselves – it is not an efficient or effective way of proceeding. When we have more knowledge, we can begin to remove the teacher, until we become fluent. When we are fluent, we are able to do the ‘higher order’ stuff independent of the teacher.
I have blogged previously about the need to adopt different instructional methods for different learners (no this is nothing to do with learning styles!). The different methods of instruction are more/less effective based upon the prior knowledge of the learners. For example, there is a body of research (Kirschner et al) which shows that direct instruction is more efficient and effective with novice learners. Essentially, they need to be told what to do, due to having insufficient knowledge to allow them to think for themselves (much like me trying to find my way around a new city – Derby). When sufficient knowledge is accrued, then the guidance can become less. Much like me driving around Nottingham. When learners acquire expertise in a subject, they are actually impeded by direct instruction according to Sweller et al (expertise reversal effect blog). This I suspect, is much like a sat nav telling me where I should go in Leicester. Sure it will send me the quickest route, but it won’t know where there is likely to be more traffic, like me. It will probably add more time to my journey.
In summary, the more we know, the less support we need; the less we know, the more support we need. How do you know what they know… initial assessment of course!
Some points I am aware of:
- The post is a bit of tongue in cheek. We all know that learning isn’t quite as simple as I have made it out to be.
- I know there is a danger of becoming over reliant on the teacher (sat nav).
- Bad teacher instruction is bad – much like a bad sat nav (I’ve hit a few dead ends in my time).
