The circuitry of my head

UnknownSo as part of the ongoing exploration of online learning or MOOCing around as i’m fondly calling it, I enrolled in a second MOOC. This MOOC is nothing to do with anything I really need to know. I am doing it for the love of learning. Suitably it is the Learning Creative Learning MOOC.

I might step back a bit here. Just a little though.

Just over a blog posting ago…

Before I found a tweet about OpenBadges and before that led me to MOOCs and the joining of, I took a small test on a whim. The test highlighted that I am motivated by learning. This is not the learning which results in a piece of paper that motivates me. This motivation is through the solid act of learning in itself. I liken this to experiencing a puzzle box.

“Before you lies a simple box unknown, locked with a mechanism that can be discovered through tactile exploration. Unlock this mystery box and whether you find it is empty or full, the satisfaction is not in the contents, but in the opening.”

The discovery of being motivated by learning resonated with me on some level. I had been feeling a little unmotivated recently and this suggested a way forward. Looking through mental lists of options I would cycle through over and over again finding not a single one that appealed. In part this is laziness: I am easily dissuaded from difficult things. In part it is tiredness: I have a lot on! In part though: it is because I lacked a motivation. So I am on a quest to find one.

Let’s step back into creative learning again.

Learning about learning…

Each week of the MOOC reading is assigned and tasks are suggested. Task 1 is around doing the reading and reflecting on it.The reading this week was around connected learning (video) as an approach which differs from traditional education by leveraging the interest of an individual and allowing that interest to develop in a way that improves their academic, civic or employment prospects. The connected element means that new media helps develop this innate passion or talent. E.g., in the plainest of terms, the writer is allowed to write for the passion of it, they post their work online and receive feedback from peers on their interest. They learn from this and eventually become an author 1.

I haven’t reflected much but isn’t there something to that (especially for those learning-motivated) which makes good sense? I don’t think it’s a new idea – there seems to be a trend recently for the internet to find a new way of doing something and for people to think that nothing like it ever happened before. I’m confident that there was connected learning before connected computers which is why I like the phrase from one of the readings: “New media amplifies opportunities for connected learning.” The internet is a massive great big amplifier of things, including learning, then. Now that I like the idea of!

The second task is much more intriguing: read Seymour Papert’s essay on the “Gears of My Childhood” and write about an object from your childhood that interested and influenced you.

Much more up my street in my current exploration of the world. Perhaps a little bit ego-orientated but internal focus helps introverts like me make sense of the world. Hopefully we then find a way to apply that externally.

So let’s jump back again. Way back this time. I called this post the circuitry of my head because it resonated with an object pertinent in my childhood. The computer. I’m adding in a second object though: DNA.

The computer and DNA

My earliest memory of a computer was in school. I’m not sure what it was. It had a game involving a train and traffic signals. It had a painting app. It was all I can remember about the machine. I played with it twice, once in Year 1 and once in Year 2. Nobody really knew how to use it beyond those two apps i’m sure. I’m fairly confident it was an IBM PC AT given what I remember about it.

My second earliest memory was when my mum and I lived with my Nan. An uncle at the time had a BBC Micro. I’m also convinced that he never really knew how to use it. One day when he was out I sneaked in and retyped in a command i’d seen him type. It was probably a load command of some kind. A while later something happened.

Here’s the thing. After those early experiences I didn’t have a computer until I was older. It was a Commodore 64. My family never had the money for computers those early years so I spent many of them still wondering about those cream white boxes with the green text or the poor colour range and what made them work. What was inside them that brought them to life.

Those same years I was learning that I was broken. That what was bringing me to life was also, slowly, destroying me. At age 8 I did not have the real comprehension of that 2. At age 8 I believe two objects in my universe collided quietly and even I didn’t notice for a while.

I found that Commodore, and the Amiga that followed and the 486 after that and the Pentium and the AMDs and the Core 2′s and ultimately the i7 i have today were all there at the moments I needed them.

I learned about computers at a time people really started to use them personally (80s). I learned about the internet arguably when it started to enter the mainstream (90s). I studied the science of computing just before it has become essential in information societies (00s) and now I am productive on a daily basis using them despite their still being an element of seperation (10s).

DNAs influence has followed a similiar trajectory. I lost any potential in physical pursuits early on (80s). I went to secondary school at a time when it became an option for those with disabilities to study in the mainstream (90s). I went to university at a time when funding existed to make it feasible for me to leave home (00s) and finally if computers didn’t exist as they do today my access to the world would be severely limited and my job would be difficult 3. Books for a start are impractical. But research doesn’t need books anymore.

So in true double-helix fashion two strands have been joined, two objects have provided a structure for my path through the world, a sequence to progress by. The DNA was an object influencing me behind the scenes, subtly limiting certain choices and promoting others. The computer was acting as a magnet pulling me toward it, clearly highlighting an interesting path forward. It’s probably also the reason my dissertation was in genetic algorithms. I still have a mild fascination with evolution today.

I think it wasn’t the only path open to me. I might have taken another path. I might have written or reported. I might have travelled or read. I might have managed or sketched. All but for one thing: I need to understand the puzzles in the boxes. It’s the circuitry of my head.

Building Blocks and MOSAIC Tiles

Booth map of Whitechapel

Booth map of Whitechapel

A few weeks ago I spotted Oliver O’Brien had blogged about using Booth style maps to present spatial data in a more user friendly way 1. An example of this style of map is shown to the right.

Oliver mapped the ONS Output Area Classification (OAC), which is a free geodemographic 2 dataset. I don’t make much use of the OAC at work, but I do use Experian’s ‘MOSAIC’ product instead which is very similiar 3. Experian produce the data at postcode level and household level.

A quick overview of MOSAIC

MOSAIC is a dataset that classifies every household or postcode area into one of fifteen lifestyle groups, or one of sixty-nine lifestyle types.The types have names like ‘affluent singles in new build areas’ or ‘older people reliant on friends and family’ and a statistical profile of characteristics behind those names. The profiles allow you to make some broad assumptions about the nature, characteristics and interests of those people. It can be a useful research tool. For example by using the MOSAIC data and comparing it to Child Poverty, we’ve identified that some groups are more likely 4 to have children in poverty than others. This means we can then focus resource on these groups first, rather than blanketing everyone in Blackpool 5.

A challenge to present

When trying to provide a summary of MOSAIC for Blackpool at group level though, I have always found it challenging to present the information in a meaningful way to complete geophobes. At household level it becomes a blur of colour 6, while at postcode level it is difficult to relate the postcode districts back to individual areas and the postcode sectors can make some groups appear more important than others.

I have tried various approaches, from dot plots to thematically shaded postcode polygons or larger areas colour coded to the most prevalent MOSAIC type. The most useful to date ended up being a very blocky postcode sector image a snippet of which is reproduced below – each colour corresponds to a MOSAIC group. Messy, impractical to identify and a bit ugly (but functional) 7

MOSAIC by Postcode Sector

When I saw Oliver’s approach I thought it would be an interesting experiment to learn how to map data in that way, and to use the same approach to mapping MOSAIC household data particularly.

Learning and Doing, Breaking and fixing

The process is actually more straightforward than I realised, if you can get to grips with software like Quantum GIS, an open source geographic information system. Essentially for me it went like this (skip this if you have no interest in doing GIS work):

  • I created a new map layer using MOSAIC household data which was basically a single point for every household in Blackpool.
  • I added in map layers from the Ordnance Survery OpenData – specifically the ‘Vectormap District’ data which is a broadly detailed dataset containing building outlines, streets, landscapes, water features.
  • I tried to spatial join the building outlines to the MOSAIC household data (essentially ‘linking’ data in one dataset to the other). This means I tried to give every building a MOSAIC attribute which I could use to colour code the map. This didn’t work well! The problem being that the first ‘point’ encountered is used to join on – so a street with 9 Group A households and 1 Group B would sometimes be categorised as Group B. Terribly misleading.
  • Plan B then! – I added building references to every point – I then exported the data, and with a bit of industrial light and magic, identified the dominant mosaic type for each building. In the example above this would result in Group A being selected.
  • I then merged this new ‘dominant’ data set to the building outlines using Quantum’s join tool.
  • The resulting map then is a map of the dominant MOSAIC group for each block of buildings.

Et Voilà!

Results below. Image on the left is the basic point map. Image on the right is the new Booth style map after joining data together. Which works for you? 8.

Comparison of point vs infrastructure map [DISCLAIMER: Points are not necessarily accurate classifications of households

I think I prefer this to the raw point data and to the original postcode sector map. I feel I can connect better with the places and streets. If I have a criticism it’s that some detail is lost in the process. In the example above a lot of the ‘green’ households are lost – you could even suspect there was none. Again feel free to ask if you’d prefer to see full maps.

There is More to maps than colour

There’s a wider issue there. The point data is often falsely assumed to be really accurate – people often point out that their household MOSAIC type is wrong. The reasons for this are a) it’s not directly tied to actual people, but to idealistic profiles so it’s a mistake to assume everything in the profiles applies to every person in the group. b) it’s often a ‘best fit’ of data – which MOSAIC group is the closest match based on data available? c)in the worst case it may just be an infilled point where no data was available and so it’s been classed as the same as the neighbouring household. d) previous residents have written to Experian to demand they are given a more affluent group so they can get that new sofa on credit 9.

For me then, I prefer the blurring of the detail to create an impression of an area rather letting people reach false conclusions about individual households. Does aggregating point data make MOSAIC data appear less accurate than it is? Interestingly the debate went slightly the other way round on the spatial analysis blog – does applying OAC data to buildings make OAC appear more accurate than it is?

I think that one is a challenge for educators and presenters – asking people to think about the data behind the picture helps.

Notes:

  1. See the wikipedia article on Charles Booth
  2. it classifies people by where they live and their social characteristics essentially
  3. but also very expensive
  4. relatively
  5. In theory at least though it isn’t always that straightforward
  6. Pointillism at it’s best
  7. Due to my own ignorance about copyright, I haven’t made full maps available but if anyone is interested feel free to ask.
  8. I’m not an expert in Quantum GIS – it would have been nice to get the street names to scale better and similiar with road lines
  9. Completely innacurrate and untrue. It was for the TV.
