How it started

Nine years ago I received the message below, which would spark a spiral of learning in the coming years and eventually change my career, although I didn't know that at the time.

Learner story - featured in edx

I have been thinking for a while now about writing an article in LinkedIn about changing careers, and this could probably be the final trigger to do it. Really honoured to be featured in the front page of the edx blog page. And happy to help as well, which was the reason why I submitted the story in the first place. Just imagine someone is inspired by this to start learning something. How cool is that? 

You can read the mini article here and browse courses here, here, here or here to name just a few platforms.

The year of the MOOCs

Today I took the exam of the fifth #MOOC I have completed in the last year. Even I am surprised of how this last year has evolved. There was no plan behind this, it simply started as a birthday present from my wife in the form of additional "time off" to take one course from MITx and it quickly developed into an addiction, if such a thing makes sense when it come to education.

I was initially attracted to #edx.org through the names of MIT and Harvard. Would I be up to the challenge? Well, it turns out I did well enough on #6.00x for me to be very satisfied. Lucky this did not exist at the time I was at college. I would have struggled with the lectures and the MOOCs :-)

After #MITx's 6.00x (Oct to Jan) I was hooked on MOOCs, so I went on to complete a couple more courses on a different platform, #Coursera. These were Georgia Tech's Computational Photography (April - May) and IIT Delhi's Web Intelligence and Big Data (April - June) before taking the highly acclaimed #Machine Learning from Stanford´s Prof. Andrew Ng , which offered a superb learning experience.

After the Summer break, I have completed Data Mining with Weka, from the Waikato University, which makes the fifth one, plus a couple of others I have audited for some lessons.

All in all I have invested a significant amount of my time on education through MOOCs in the last twelve months. I took much fewer photos this year, I read fewer newspapers and blogs, watched much fewer movies and, in exchange, I focused on something I am convinced it will have a long time benefit, my education. The courses were heavily weighted towards Computer Science, which meant challenging programming assignments beside simply watching the videos and reading additional information.

So what´s next? Well, there is a course about Semantic Web offered by the HPI which caught my eye because of something related to work. Plus there is the XSeries offered by MITx, which I will definitely endeavour to follow. Plus so many others that, again, the problem is making up your mind which one to take. Something I learned this last year is that two MOOCs at a time is one too many for me (tried Harvardx CS50x at the same time as MITx 6.00x and did not work since both demand quite a bit of time, plus I had trouble with Web Intelligence, Computational Photography and Machine Learning partly overlapping for some weeks).

So this was my particular year of the MOOCs. Very enjoyable...

Visiting MIT...

On the way back to the airport a few days later, and as you can see from the photo above, I had a bit more luck with the weather. I stopped by in Cambridge once more, as Prof. John Guttag at MIT Computer Science and Artificial Intelligence Laboratory had kindly made time on his schedule to meet me. We talked briefly about my experience taking the 6.00x course and he gave me a signed copy of the Spring version of his book, the one which includes me in the acknowledgements.

Just by chance, I had bought the big book "The Human Face of Big Data" a few days earlier in Hartford (seriously, it´s really big and won´t fit on my shelves!). John Guttag and fellow researcher Collin Stultz appear in this book and their photo was actually taken in the Stata Center. As I needed a photo for an internal newsletter from my company, John agreed to have one taken and he suggested that we do it in the same spot as the one in the book. Quite memorable!

Finally, I also found time to visit the edX offices, just a few hundred meters away. I just showed up to the entrance and asked to see one of the staff, whose name I could remember from the forum discussions. Luckily she was there and, surprised as she was, she took some time to show me the offices and talk about MOOCs and the challenges they are facing. All in all, a great experience before rushing to the airport for my flight back home.

I am very grateful for the effort that goes into making these courses freely available, so when edX asked for stories from students, I sent mine hoping it would be useful. I don´t usually post photos of myself, but I felt this was worth it and I am very happy that my story has been featured on their facebook page.

If you have not done it yet, have a look at edx.org or any other of the platforms offering MOOCs. You will be stunned by the quality of the courses.

Python & applying knowledge gained in an MOOC

I recently saw this at a school biology lab here in Berlin. When I read the (very) old label and noticed that these were two pythons, I took my blackberry and snapped the photo above. There was a teacher next to me so, rather apologetically, I explained that I had recently finished a programming course and that the name of the language was Python! She smiled at me and probably thought I am nuts. Maybe. Maybe not.

But I actually wanted to write about something else today. There is a lot of hype about MOOC´s and all the stuff that can be learnt these days for free. But learning without applying your knowledge later is sort of useless. OK, you get a certificate (and apparently mine from +edX will be ready tomorrow!), but that is not the whole point of doing a course, is it? In contrast, most of what I read about Raspberry Pi´s are actual applications of what people are doing with it. You don´t buy a Pi just to tick a box of cool things to own, but because you have a project in your mind and you are itching to get started with it. It should be the same with programming. 

I am happy to say that I have already applied some of what I learnt on 6.00x at work. I have developed a simple search tool which actually makes life in my department a bit easier. It allows to search a huge repository of documents from an old system in a way which was not possible before. It is not rocket science, and surely many a professional programmer would find ways to do this in quicker and more effective ways. But it works and it reduces search times from hours and hours to a few minutes. And I have the feeling this is just the start. I recently came across this book and, time permitting, I already have something else in my mind. Again, it is not about learning Python for the sake of learning. It is what we can now do. And I have a feeling it is a lot that we can do!

So how are you applying the knowledge gained from whatever latest MOOC you took?


PS: I know, Python did not get its name because of the animals...

MIT - 6.00x

Quite predictably, I passed the exam and the course. Actually, I got an A, which is sort of nice thinking which institution is behind the course. From the stats I´ve seen, literally thousands of people did drop half way through the course. So finishing it and passing is, by no means, a given. Even less getting the top grade. 

So thank you to my wife for this wonderful birthday present. And now it´s time to apply the newly gained knowledge...

MIT - 6.00x Final Exam

Just got the e-mail that the exam window is now open. In my case, I have been in bed for the last few days with a persistent cough and I am late with reviewing, which now looks like it will mostly happen on Saturday. I have already passed the 55% line anyway, thanks to my scores on the mid term exams and the problem sets, so it is really a matter of honour to try and get a nice grade (the final is worth another 40%), but knowing I am already through definitely takes some pressure off (which maybe also explains why I am so late with reviewing). I am currently planning to take the 6.00x final exam on Sunday morning, for which the instructions say I should plan four hours. That´s a full morning and leaves me Sunday afternoon to relax. And probably to start thinking which course to do next...

Acknowledged

As mentioned on earlier posts, I am taking the MITx 6.00x course, Introduction to Computer Science and Programming. The textbook is available online in the edx platform for the students, but it is such good value for money that deciding to buy the paper version is a no-brainer. 

As it happens, I found a couple of typos while reading the book and, since it is a print on demand book, I decided to write back to the author, Prof. John Guttag, to make my humble contribution to the course. To my complete amazement, I got an answer encouraging me to keep up sending typos, which I did. Eventually Prof. Guttag asked me if I would agree to appear in the Acknowledgements for the Spring edition. I cannot even start describing the joy I felt... It was about the same I felt a few minutes ago when I noticed the Spring edition is already available as e-book and, indeed, I am in the Acknowledgements page!

Como ya he mencionado antes, estoy haciendo un curso online de la plataforma edX. Hay un libro de texto disponible online para los alumnos, que también se puede adquirir como libro impreso. Dado su reducido precio y la alta calidad del contenido, no tuve que pensar mucho si merecía la pena comprarlo o no.

El caso es que cuando empecé a leerlo encontré un par de errores tipográficos en los primeros capítulos y los fui marcando igual que hago cuando reviso los informes técnicos de mi equipo en el trabajo. Pensando en ayudar, aunque fuera mínimamente, a mejorar un poco la experiencia de aprendizaje del curso, le mandé un mensaje al autor, Prof. John Guttag. La sorpresa fue mayúscula cuando me contestó él mismo agradeciéndome el mensaje y pidiéndome que siguiera mandando mensajes similares al continuar con el libro. Para cuando lo acabé, había hecho suficientes comentarios como para que el autor me ofreciera estar en la página de agradecimientos, algo imposible de rechazar. La edición de primavera ya está disponible como e-book y, efectivamente, el J.C. Cabrejas que aparece mencionado soy yo!

Como +Enrique Dans dice muy a menudo, la bidireccionalidad que ofrece internet es una gran diferencia y algo impensable no hace tanto.

MITx - 6.00x Midterm Exam 2

So far so good. Just finished the second midterm exam, well below the two hours provided and with a score which is even higher than in the first one.

It´s been a hectic week, at work, at home, online finishing the last pset and reviewing the book in preparation for today. Time to relax now and go out and play in the snow with the kids.

PS: This blog only receives an extremely modest number of views per day. Somehow, during the midterm exams the number of visitors grows by an order of magnitude. While you are all welcome, I hope it is not fellow 6.00x students looking for the answers. Remember the honour code!

MITx - 6.00x midterm exam

The first midterm exam of 6.00x was due today. I woke up at 5am so that I could have some peace and quiet before the kids get up. It took me two hours to go through the exercises, which were not particularly easy (but doable).

This T-shirt must be more than 15 years old. I found it on my wardrobe a few days ago and thought it was quite appropriate.

In case you are wondering, I scored 1011111 out of 1100100 :-)
