One of the things I’ve enjoyed least about my OU Maths journey so far has been group theory. I ploughed through whole swathes of M208 applying the techniques and not really seeing the relevance1 I found group theory and the proofs related to it tedious. Mainly because I was proving something that was “obvious”. However, I’ve always had a healthy acceptance of partial learnings – knowing that if I was being taught a technique then there was a reason for it. Two years later and that reason finally hit me.

I gave myself a birthday present again this year, by registering for another 60 points worth of Open University maths modules. I’d put it off for quite a while as I couldn’t decide which level three modules I wanted to do most and also in which order. The only fixed option was “The quantum word” which was only available once I’d completed1 60 points worth. This left me with a choice of 3 modules from 4 other interesting options. Sadly, I discovered (thanks to a comment) that the pure maths module I intended to do was a 60 point module, meaning I either had to lose that from my choice or two of the modules I was really wanting to do. In the end, pure mathematics lost out and I’m committed to four 30 point modules. Continue reading OU level 3: Complex numbers and stochastic dynamics
This week was results week for the Open University. Many of us who had been checking the website weekly since the exam1 finally got the link through to our overall module scores. If, like me, you were waiting for a result then I hope you got what you needed2. MST210 marks the end of level 2 of the B.Sc. Mathematics and I now have some choices on level 3. Continue reading OU Maths – decisions on level 3
This week I was delighted to be at the Royal Statistical Society as a business representative for the launch of their Data Science Section. At over 160 years old, the RSS is one of the more established professional bodies and I like that it is questioning and making a difference as the application of their industry changes and when faced with an increasing challenge of abuse of statistical methods. I wish the general public had a greater understanding of statistics so they wouldn’t be so easily swayed by the media with a simple graph “proving” a point. Continue reading Professional body for data science? Yes Please
This week was the exam for my level 2 OU module MST210 on methods, models and modelling. This was a compulsory module, but had it not been I would have never chosen it. The module has been mostly applied maths, which has been really interesting, but what’s been a problem for me has been the mandatory team work modelling exercise, which makes up 16% of the continuous assessment. So much so, that I lost motivation to do the final TMA or revise for the exam as much as I wanted to. I thought it would be worth a short reflection on why I disliked this aspect so much (especially as it led to a repeat of last year when it came to revision…). Continue reading MST210 – Exam and modelling exercise reflections
After the lack of focus I’d had studying for M208, I was adamant that with MST210 I’d get into a routine and stay on top of the work regardless of what else life through at me. This worked pretty well in October and November. I did the work during my commutes, approximately 3-4 hours a day, even if I had to sit on the floor of a train carriage or find a dusty corner of Paddington while waiting for a delayed train. All was going well. At the end of November I began the process of changing jobs and, because of the nature of my work, was put on garden leave for three months. Suddenly I wasn’t confined on trains for about one seventh of every weekday. This is where my whole routine broke down. Continue reading MST210 – Lack of routine has consequences
I’ve written before about the power of literate programming, using to create reports when code runs. It’s fairly simple to combine this with the graphical drawing packages to create impressive graphs and figures on the fly. A lot of academics I’ve spoken to have shied away from using for drawing, despite being very proficient with the textual layout. Similarly, a lot of students on the OU Mathematics degree write up all of their assignments in but drop in hand drawn graphs and diagrams. Just like anything else in , once you get your head around how it works, it’s actually not that difficult to create very complex structures. Continue reading Diagrams with LaTeX – easier than you might think
I get a lot of attention when using my surface for note taking at work, studying on the tube or train and during OU tutorials, making full use of multiple notebooks, tabs and pages in OneNote. I’ve written before about using the surface but following a discussion after my most recent tutorial I realised I hadn’t covered the way I use it along side the OU’s electronic TMA submission process1. A lot of people on the same maths course as I am tend to use and typeset their marked assignments. While I am a great fan of and appreciate how clear this is for the tutors to mark, I have always preferred to hand write assignments. While there is some aspect of writing by hand helping to cement ideas more than those typewritten, the main reason I prefer to handwrite is that the exam is handwritten. If I don’t force myself into regular, neat mathematical writing then it’s easy to make mistakes in the time pressure of the exam. Simple things like forgetting to underline vector or matrix definitions can cost marks and if the examiner can’t distinguish a 0 from a 6 then you’re going to be in trouble! Continue reading Using OneNote for Open University TMAs
If you’ve been reading my blog for a while you’ll know that I start off with good intentions for my OU modules and then finding myself rushing TMAs, skipping a lot of the text and generally revising the day before the exam. While I’ve got away with this so far, it is getting harder to get the scores I want and I knew going into MST210 that my focus and time management would need to improve to take this seriously.
One of the things I took into account when doing this module was the amount of time I spend commuting. Working in London I have a train journey of between 30 mins and 1 hour 15 (depending on whether I travel in rush hour or not) and a tube journey of 27 minutes (fortunately on a single line) in each direction, so at a minimum I have 2 hours on public transport in four good half hour blocks. That’s 10 hours study time a week, which should be sufficient1.
I’m getting a head start on MST210 as with previous modules I’ve fallen behind due to work commitments and I don’t want to impact my family time playing catch up as I did last year. I’ve done one full week and completed book A unit 1. This is on par with the pace that the study calendar sets2 and I have made notes on all the examples and done every single exercise in the unit.
Keeping focus has been really hard. It’s really easy when you’re on a train at 6.30am to sip coffee and stare out of the window as you wake up gradually. It’s so easy when you get on a train or tube and have to stand to just leave my surface and book in my rucksac and play Peak on my phone. It takes no effort after a day at work to grab a gin and tonic and read my Kindle. What is hard is having that focus and discipline to make every minute count – every minute I spend geting ahead now is a minute I can spend having fun with my family rather than having to isolate myself to rush that TMA. It seems like a no-brainer, but humans do tend to make short-term decisions at the expense of long-term success . One of the best things we can do to overcome how our brains work is have a routine and stick to it3.
This is what I’ve been doing – every morning and evening, I’ve forced myself to get my MST210 books out, not only when I’m actually on the train/tube, but also while waiting for them – I keep them in my hands while changing trains; if I don’t put them away, then there isn’t the effort to get them out again. If I need to sit on the floor of a train so I can write, then that’s what I do. This focus has taken a lot of effort and I’m not sure how long it will be before it’s automatic, nor indeed what will happen when my routine changes due to business travel.
However, backed by the science that our brains are dumb enough to make bad short term decisions even if we are aware of the long term consequences, I know that the focus I need is entirely in my own control and if I stick to the routine long enough, it will become the go-to task for my selfish limbic system.
Today, after a lot of pondering I finally signed up for MST210 to start in October. This is the second 60 point module and, just like M208, is mandatory on the BSc Maths pathway. I’d been holding back for a number of reasons and reviewing my post from last year, I realised that nothing had changed. If anything my job is now more mathematically demanding as I dig deeper into the bleeding edge internals of machine learning. My 3D printer is nearly finished and my daily commute is now 3 hours a day, giving me 2 hours a day sitting on trains. That time is currently occupied with getting through a ridiculous amount of books1. What I really want to avoid with MST210 is some of the rushing that I did for M208 – I want to enjoy this module.
