Do you really need a degree to enroll on a postgraduate course?

One of the (many) non-teaching duties I have to do is to review applications for courses - it is as a Course Director that I have to do this, not as a Lecturer. I am Course Director for an NFQ level 8 Higher Diploma. There are set criteria for applicants, this is regarded as a postgraduate course - so it is relatively easy for applicants with a degree to be accepted. But what about those without a degree?

First - let's take a look at the word "postgraduate". It means that you should first be a graduate before continuing on this path of study. Courses such as these are designed for students who have completed undergraduate degrees. A BA or BSc is the ticket you need to get into a postgraduate course. There is no doubt in my mind that studying for a degree prepares students for postgraduate work (and academics all over the world share this belief). Studying through 1st, 2nd, 3rd, and 4th year builds students' learning abilities and critical skills such as higher-order thinking and problem solving. Also - there is no doubt that the ability to write good essays also develops over the four years of study. Learning outcomes at NFQ level 8 demand a significantly higher ability than lower levels. In all, a degree is an ideal requirement for postgraduate study. 

Nevertheless, many people who apply for postgraduate courses don't have a degree. Many universities will not accept non-degree holders. The message very often is - "Come back when you have a degree". Some Colleges, such as NCI, offer a path through what we call RPEL (Recognition of Prior Experiential Learning) to get into postgraduate study. The idea is that applicants may have lots of experience that will enable them to complete the postgraduate course. For example, suppose a computer programmer with 10 years experience in software development, and who has set up their own company, applies for an MSc in Technology. Arguably they are more qualified than a fresh BSc in Computing graduate who has never worked on real software development. Usually I would recommend to the Admission Office that in a case such as this that the applicant be admitted to at least a level 8 course. 

Basically - the idea of RPEL is that if you can demonstrate that you have done the equivalent of achieving the Learning Outcomes of a degree programme, then your experience qualifies you for the programme.

However, many cases are less clear than above and it becomes a little more difficult when applicants have experience that is short or not so relevant. I am then asked to judge whether they are capable of completing the postgraduate programme. This is not a pleasant task as often an applicant is highly committed and motivated to participate in a course that might change their lives. Some such applicants succeed very well, though many do find it tough and drop out. A one year Higher Diploma is a very attractive option for someone seeking a level 8 qualification compared to having to go through 3 or 4 years for a primary degree. Often my head says "No" and my heart says "Yes". I've no desire to put barriers to education in front of applicants, but I am mindful that it is a postgraduate course that I am dealing with.

NCI's mission statement is "To change lives through education". I reject very few applications.

I deal with level 8 applications only.

My First "How To..." @YouTube Video using @tableau Software #FilledMap

Later in this upcoming semester I will be using Tableau Software for the first time in my Statistics classes. I normally run a lab session on visualizing data: first I used Excel, last year I added SPSS, and this year I will add Tableau to the lab. Tableau is free to students and academics for learning and teaching purposes, though a (free) license is needed to run the software. Many students have already been using Tableau in projects, and there certainly has been a demand for more experience in data visualization tools like this.

For the video below I used a simple data table from the "Living in the EU" web page - I selected "Quality of Life" data showing the GDP by country. While this is easy to chart in Excel using bar or pie charts, the idea is to see how this looks in filled map (a kind of heat map) using a map of the European Union. The video also shows how good Tableau is at recognising different data types. Hopefully I can create few more for my students to help them get through the lab.

Flipped Classroom - "professional suicide" for Lecturers (via @jhrees)

Writing in The Kernel on 23rd August last, Jonathan Rees asks many questions about one of the latest trends in third-level education - his article is entitled: The ‘flipped classroom’ is professional suicide*. Clearly no fan of this trend, Rees wonders about "pedagogical problems" such as how his students "would find time to do their assigned reading if they were watching class videos in their dorm rooms three times a week" and what would his other students "be doing while I [he] personally interacted with other students". Later in the articles he raises questions about "copyright issues" and "competition" with the Internet.

I find myself agreeing with Rees, though I have to say that I have not tried to formally adopt a flipped classroom methodology (is it a "methodology"?). While I do create and upload many videos to YouTube for my students, I still use class time for traditional lecture and tutorial work. Some of my colleagues use the flipped classroom with success and feedback from students seems to be good so far.

There is an interesting (unattributed) quote in Rees' article:

Why should you lecture, when you can get some hotshot from Harvard to do your job for you?

This is a hard one to agree or disagree with. As a learner I definitely would prefer an on-line lecture on a subject from a Professor at Harvard who has written books on the subject and has been teaching it at Harvard for many years, compared to an inexperienced part-time lecturer who has never taught the subject before. While lecturers, especially younger ones, must start somewhere (we all remember that first time we taught a module) the temptation to go for the Harvard professor as a learner is huge. When College management are deciding who teaches what, some subjects are inevitably given to new and inexperienced lecturers (who in time may become great teachers and experts in their field). When it comes to exams, the Harvard professor does not set these and there is the dilemma for students on which set of lecture notes/podcasts to study in preparation for exams (the good stuff from Harvard, or the class notes on which the exam will be based).

In 2010 I started (and completed) the free Harvard University course on "Justice" by Professor Michael Sandel. There were 12 lectures in this course and I enjoyed every single one of them. In short, this was the best on-line class I have ever "attended" - it would be hard to get a better set of lectures than this. So - what about this for a dilemma? What if your College had a module on "Justice" in one of its courses? As Professor Sandel himself might ask - what would the right thing to do be? Should Sandel (the best) be on the module timetable? Could/should he (or Harvard) be paid for this? If a new lecturer is assigned, should they create their own material or use Sandel's (I use his train wreck story from lecture #1 in my class)? Should Sandel's course be on the module Reading List (or video/podcast equivalent)?

As a leaner I know which I'd go for, but as a Lecturer the decision is more difficult. I don't want to be a turkey voting for Chistmas, and talk myself out of a job - but I do see more more flipping happening in the future. If a course has several flipped modules, it would be easy to trawl the finest Universities for on-line content and say to students - "Watch this video and we'll discuss it in the next tutorial". This would save a lot of money. The temptation for Colleges/Schools to do this will become more and more real. The availability of top class content combined with tight or decreasing budgets will (I believe) force Colleges to rethink how they allocate teaching duties. When you think about it - what is wrong with creating a full degree programme with modules taught by experts from Harvard, MIT, Oxbridge, or any of the top-class Colleges around the world? Expensive Lecturers would no longer be needed! Learners would get the best education available and Colleges would save a lot of money that could be put to other use (such as research).

I just hope this doesn't happen before I retire in 10 years time!

How To... Calculate the Percentage of a Number in Excel 2013

I've always been confused when calculating percentages. If I want to determine what is 15% of 456, I have to always check if I am using the right method to calculate. Sometimes I have to do a simple calculation first - eg, use a formula to calculate what is 15% of 100 - if I get a result of 15 I know I am right. In Excel I use formulas to do the same, but am always wondering things like should I divide or multiply by 100? Where should the numbers go?

So I decided to make a video to remind me how it is done, and hope that this will also help other "percent" challenged folks out there in YouTube land. Here is the video:

First Metered Water Bill #IrishWater

Yesterday I wrote about Irish Water and the work of Geoffrey Drage on statistics, and coincidentally today I got my first metered water bill. This is just the second bill I've received from Irish Water - the first was a fixed reading with a cap €64.82. 

I'm sure that like many people I wondered what would I have paid if the cap was not in place and I had to pay for every litre used. In my bill below we used just over 20,000 litres of water during April/May/June - I'm visualizing the 1,000 litre oil tank in my garden and at 20 of these, this does not seem like a lot of water. Had my bill been based on usage it would have been just over €10 higher - not a lot. This is not so bad after all???

Have We Learned Anything in Nearly 100 Years? #Statistics #BigData #IrishWater via @ad_greenway

In a short story by Andrew Greenway on data and digital, he writes about the work of Geoffrey Drage nearly 100 years ago. In December 1916, Drage presented a paper to the Royal Statistical Society on "The Reorganisation of Official Statistics and  a Central Statistical Office" (available in Jstor). This paper was published in the Journal of the Royal Statistical Society (Vol. 80, No. 1, pp. 31-64) in 1917. 

In 1916 there was no Central Statistics Office in the UK (Ireland of course was part of the UK until 1921), and when I read some of the key findings of Drage's paper I wondered have we learned anything about data and statistics since then. With more news this week from Irish Water of new databases, plus the lack of existing data when the company was set up, and the difficulties they are having with errors - I thought I was reading a list of things wrong with Irish Water (and other bodies), when I read the following findings by Drage:

In 1916, Drage diagnosed six problems with government statistics as follows:
  1. Lack of cooperation between the different departments
  2. The absence of any central or general supervision of national statistics as a whole
  3. Publications (such as the Parliamentary Blue Book) serving conflicting purposes, confusing users like administrative and departmental officers
  4. The inclusion of departmental reports of quantities of matter for the purpose of showing how much work is done in a year
  5. The fact that compulsory powers are too few and seldom applied
  6. Defective supervision in the collection of statistics and the employment, especially for census work, of ill-paid, uneducated, and therefore uninterested persons in the collection.
With the exception of the point #6 above, the others make for interesting reading (though in #6 above you could make a case for front-line staff today being under-valued. It wasn't until 1941 that a Central Statistics Office was set up in the UK when Churchill got fed up with bad data during World War II. The CSO in Ireland was set up in 1949 (we didn't need a war).

It seems to me that problems at the bewildered Irish Water Company with new databases, PPS numbers, data protection, and joining the dots seems to have learned nothing in nearly 100 years. Expect lots more data analysis mess to come!

"How To... Add Music to a PowerPoint 2013 Presentation" - new @YouTube video

In an effort to boost video views on my YouTube channel I have looked back at some of my popular videos in PowerPoint and Excel versions 2010, with the aim to update them for version 2013.  While writing this post, my "How To... Add Music to a PowerPoint 2010 Presentation" video has 365,943 views. So it is the first of a few that I will create a newer version of over the next couple of weeks. 

In this video I show how to insert and play an audio file (I use the free Kalimba MP3 file that comes with Windows) on a slide. I then show how to play the audio this across slides, and finally show some of the basic editing features available in PowerPoint.

Book Review: "The Wright Brothers" by David McCullough

One of the top books (#4 as I write) on the New York Times Best Seller List this summer is "The Wright Brothers" by David McCullough - the great story of the history of aviation with Orville and Wilbur Wright as the central characters. The story of how these two pioneers of aviation were the first to fly a heavier than air powered airplane (the "Wright Flyer") at Kitty Hawk in North Carolina on 17th December 1903 is reasonably well-known - but there was more to it that that single day. nI bought the paper back version to read on holidays in Italy

Image Source: Amazon.
David McCullough has a very easy to read writing style. This is a well researched book that traces the origins of the Wright brothers' burning desire to fly just over 110 years ago. Today it is difficult to look up to the sky and not see a jet or their white trails - we take flying for granted. But in the years before 1903 several aviators around the world were in a race to be the first to fly - the Wright brothers got there first.

Their story is one of perseverance - they had made many attempts before they finally got it right (see famous photo of this flight below). The relationship between the two brothers undoubtedly helped them to succeed as they were very close and worked well together. Neither brother every married - too devoted to their work. The book does not stop at the Kitty Hawk flight as it tracks subsequent brothers' efforts and those of others as aviation was a new horizon at the beginning of the last century. The founding of a company and the rivalry between countries to build airplanes based on their design makes for further fascinating reading. Wilbur's early death in 1912 perhaps robbed the 20th century of one of its most brilliant inventors before time.

As you might expect, there is much more to the story of the Wright brothers than the flight at Kitty Hawk. This is a fascinating popular history read that I heartily recommend to anyone who has ever set foot on the steps of an airplane stairs.

Book Review: "The Boys in the Boat" by Daniel James Brown

I love my Kindle Reader on my iPad, but reading from it in the sun is very difficult. So for summer holidays I decided to buy a couple of paper books to read in the sun. I looked up the New York Times best seller list on-line to see what Americans were reading this summer. "The Boys in the Boat" by Daniel Brown (not the one who wrote The Da Vinci Code) was at the top of the list and sounded interesting, so I went to Hodges Figgis on Dawson St  in Dublin to buy. In reading the description of the book it reminded me a bit of Laura Hillenbrand's "Unbroken", which I previously read and reviewed.

Image source: Amazon.
This book tells the story of Joe Rantz and the University of Washington rowing team who won gold at the Berlin Olympics in 1936. It is also a story of the depression and how a boy like Rantz managed to overcome poverty and family difficulties to not only study at university, but also to be a key member of the rowing team. The rivalry between UW and other colleges, particularly from the east coast, is fascinating, and builds up nicely to the Olympics. The boys in the boat rowed to victory in front of Hitler and his Nazis. They did not get to fight Hitler in World War II because they were too tall for the army.

While the story is fantastic, there is a lot about rowing in this book. The terminology and the endless training that the boys went through does get a bit boring. Once one race is done, it is back to training and onto the next - then more training and more races. However, this is a trivial compliant in an otherwise excellent book.

Dramatic fall-off in YouTube views

In the past I have never been slow to (boast) report about reaching milestones such as 7 or 8 million views on my YouTube channel. Since I founded the channel in 2006 the rate of growth has been steady and followed fairly distinct patterns. 

I expected (and hoped) for growth to continue - on 25th March 2014 the channel reached a record high daily view of 11,944 views. Had previous patterns been followed, this would have been exceeded later in 2014 and nearly doubled by March 2015 - not so. While late 2014 and early 2015 were similar to corresponding periods 12 months earlier, since May this year there has been quite a dramatic fall-off in views, dropping down to 2012 levels, and even lower than Christmas 2013 and 2014.

I have no explanation for this. In April/May this year I did introduce custom thumbnails and updated keywords/descriptions on the advice of my YouTube Partner Manager. I'd be really surprised if this caused the drop-off, as most of my views are the result of searches in YouTube and these changes should have improved that. Perhaps this fall-off was going to happen anyway if I had reached a saturation point. I have been adding more videos, and hope to keep this up in the next few months - but it has always taken time for a new video to gather views

There is some evidence in the chart above that the downward trend is reversing, this normally happens after the summer - so hopefully it will soon be in five figures a day again.

New Book: "Exploring Northern Ireland's Causeway and Mourne Coastal Routes"

This morning I have published my third book!

Following on from "Exploring Ireland's Wild Atlantic Way" (which is now out of print), I have written about the Causeway and Mourne coastal routes in Northern Ireland which I toured last year and revisited this summer. It has taken nearly a year to write (including several episodes of writer's block and laziness). Much of the time was taken in formatting photos and inserting them in a way that does not disrupt the flow of text. The book is self-published through CreateSpace, and the process of uploading and re-uploading files took quite some time.

The book is short (113 pages) - the two routes are way shorter (500 kms) than the Wild Atlantic Way (2,500 kms), so inevitably there is less to write about. While I was reasonably familiar with the Co Down coast, before 2014 I had never been north of Belfast or east of Derry. For a bike ride - it doesn't get better than these two routes. The A2 road runs right along the coast for long stretches, and with sites like the Giant's Causeway, the Mussenden Temple, the Glens of Antrim, and the Mountains of Mourne - it is arguably as good as, if not better, than the Wild Atlantic Way. The WAW takes a long time (10 days for me), so the CCR and MCR are ideal for a shorter trip (3-5 days).

The experience of self-publishing through Amazon's Createspace was interesting. First, there is no stress with trying to get a regular publisher interested - I did not submit this book to any publisher. No rejection letters! The quality of the printed proof I got was very good - I'm keeping it as my first copy. Createspace will print the book to order, but this makes it expensive. The minimum I could sell it for is $22.50, so I really don't expect to sell very many at this price for such a short book. At the moment, it is just  available on the Createspace Bookstore, but it will be available on Amazon in 3-5 days. I can make it available as a Kindle book which I plan to do next week - this will mean that it can be a lot cheaper to buy.

Both my WAW and CCR&MCR books cover exploring the Irish coast from Kinsale in Cork to Newry in Down. The coast from Newry to Kinsale around the Southeast coast is a natural follow on - and this is my next book project. Much of it is already written, though I may need some more photos.

Touring South Wexford

Yesterday I took advantage of one of the few rainless days this summer and decided to tour around the South Wexford coast. It is three years ago since I first set out to complete a circuit of the coastal roads of Ireland. I had started to write about my explorations as soon as I got home, beginning with South Dublin and continuing on to Wicklow, Wexford, Waterford, and Cork. The intention was to write a book (tentatively called "The 100 Corners of Ireland") about the entire trip, but it has ended up in three parts: "Exploring Ireland's Wild Atlantic Way" (published in 2014), "Exploring Northern Ireland's Causeway and Mourne Coastal Routes" (published in 2015), the third part will be "Exploring Ireland's East and South-East Coast" (hopefully to be published next year). When I originally started I did not have the intention to include photographs (even though I took hundreds).

I did not have that many photos of the Co Wexford coast, so my trip yesterday was to put that right - below are a sample of some of the photos I took:

Kylmore Memorial Garden.

Outside Sinnott's Pub in Duncormick.

Bannow Church (where the Normans first landed in 1169).

Inside Bannow Church.

Ruined Church in Wellingtonbridge.
