Good Font, Bad Font

16 November 2014 by · 2 Comments · Uncategorized

Introduction

I have been an occasional student of fonts ever since 2010 when I designed a font for an organisation. I have also watched with interest fonts aimed at dyslexic people. All these fonts are aimed at improving the visual readability of “printed” text, and we have come to take for granted the efforts of font designers. To put their efforts into some relief, I thought to make a font that sets out to be very difficult to read.

Some Design Ideas

We have grown used to having a number of features common to any particular family of fonts. For example,

  • curves are common
  • the visual bulk of lower case letters tends to avoid the top edge
  • upper case letter usually have a stronger presence on the top edge
  • each occurrence of a letter looks exactly the same every time

The task was to design a font that turned as many of these features as possible on their head.

The Result

The result was built around using straight lines that went from point to point on a rectangular matrix. The lines themselves came in two different thicknesses. The thickness of each line was chosen at random. The result looked like this:ugly_font_1People of a masochistic nature will notice that the text in the image above are the words at the start of this post.

Enough of this foolishness. :)

Should We Let Students Struggle?

26 July 2014 by · 1 Comment · Uncategorized

ACKNOWLEDGEMENT

My thanks goes to Aviva Dunsiger (web site http://adunsiger.com/, twitter @avivaloca) for prompting me to write this post. She made the following tweet:avivalocato which I repliedavivaloca_1
Aviva then expressed interest in how I had done so, hence this post.

OBSERVATIONS

The nature of the struggles that I set are governed by the subject that I happen to be teaching. The struggles needed for mathematics are quite different to those for English, for example. The subject of computer programming lends itself to making the nature its struggles easily explained.

LEARNING ACTIVITY
It is my practice to create learning activities where the goal is made explicit at the start, and the learners then have to solve a series of problems to be able to reproduce that result. For example, the goalrgb_resultcan be achieved with the following code:
private void show_colours() {
red_value.setText(String.format(“%d”,red_slider.getValue()));
green_value.setText(String.format(“%d”,green_slider.getValue()));
blue_value.setText(String.format(“%d”,blue_slider.getValue()));
show_red.setBackground(new Color(red_slider.getValue(), 0, 0));
show_green.setBackground(new Color(0, green_slider.getValue(), 0));
show_blue.setBackground(new Color(0, 0, blue_slider.getValue()));
show_rgb.setBackground(new Color(red_slider.getValue(), green_slider.getValue(), blue_slider.getValue()));
}

To present the above text to learners would simply be to over-face them. The learning activity consists of describing what each word means (for example, “setBackground” sets the background colour of something on the screen), and offering a collection of “code fragments” which they can use to build a working program. A “code fragment” can look like this:

show_blue.setBackground(new Color(0, 0, blue_slider.getValue()));

The struggle then comes down to three components:

  1. Understanding how each code fragment works internally;
  2. Working out how each code fragment contributes to the goal;
  3. Figuring out how to assemble all the code fragments into a working whole.

The learners are usually very quiet during this activity: it is rare for any learner to ask anything. The learning activity allows self-evaluation: when the learner has completed it successfully, they know immediately. The most common issue that I find in such learning activities that a learner may have mistyped something, which then affords an opportunity for a whole-class discussion on debugging. In my experience, learners always feel happy when they complete such learning activities, and one learner went to far as to shout “Hooray!” to the whole of the class when he completed it.

CONCLUSION

I suggest that this can be related to similar problem-solving issues in other subjects. Using English composition, for example, how do you want to break down and organise your ideas in a blog post so that they are presented logically and can be easily understood by your audience. And at the risk of turning this blog post in on itself, you may care to critique it for those qualities.

Trouble with (information) technology (or: A Study in English Composition)

31 May 2014 by · 1 Comment · Uncategorized

A Good Start

I was recently in Adelaide, and I had cause to use a car park courtesy (if that is the right word) of Wilson Parking. The entry to the car park offered the use of a credit card by way of payment, with its obvious means of identifying both the duration of the stay in the car park and a means of payment upon exit. The entry was quite uneventful, with me inserting and retrieving my credit card in a wholly natural way.

Things Start Getting Exciting

Having spent a pleasant time in Rundle Mall, I returned to the car park to pay for the privilege using it, and my subsequent departure. It is at that point that things became exciting. The pay station that I used had a credit card reader, much the same as the credit card reader that I had used upon my entry to the car park. I put my credit card in, and nothing happened. I tried to extract my credit card, but without success. I then used a second credit card to force the first credit card in so far into the credit card reader to try to cause it to eject the first credit card, but still nothing happened. The credit card reader was plainly malfunctioning: it had failed to accept the first credit card, and it had failed to reset itself under a fault condition.

There was a communications station next to the pay station, complete with push-button, speaker and microphone. I pushed the button. Nothing happened. I pressed the button for longer, and still nothing happened. After about six attempts, all unsuccessful, I called the help telephone number displayed beside the communications station. The first call was dropped. The second call was dropped. I got through on the third attempt. The first question that I was asked was “which car park?”. I had no idea. There were no identifiers showing the car park in which I found myself. It was only the kindness of a passing stranger that help me to provide an answer. It took a very long time for the person at the other end to finally comprehend what had gone wrong, at which point me she informed me that the manager of the car park would arrive in 15 to 20 minutes to retrieve my credit card. He arrived late.

In the meantime, my partner had gone to a second communications station, and had got through. She informed the person at the other end that the communications station that I was using was non-functional, and the person at the other end denied that this was the case. She was asked by the person at the other end which pay station was causing the issue. There were no identifiers on either of the pay stations.

While we were waiting for the manager, we were informed by other car park users that these pay stations had a reputation for swallowing credit cards.

The manager turned up, and was unable to retrieve my credit card. He felt the need to ask me if I actually had a credit card in the reader. He then stated that he would need to get a technician in to retrieve my card, and that this would take some time. We agreed that we should make contact with him in an hour or so. As we were planning on going elsewhere at that time, this then raised security issues, and the manager stated that me quoting the first four digits of the credit card would be an adequate identifier. Anybody with even a rudimentary knowledge of credit card security knows that this is inadequate.

I work with information technology as a matter of course, and I am normally more tolerant that most other people of its foibles. When we left the car park, I was livid and my partner was distraught.

An Analysis

I formed the following opinions, and here I must choose my words with extreme care, this for obvious reasons.

  • The pay stations also had a ticket entry point, and appear to require the insertion of a ticket (not provided to me at the point of entry), before the insertion of a credit card. This might indicate a failure to fully think through how the whole system worked.
  • The software within the pay station was inadequate. Whether this was due to an inadequacy of the Use Case diagram at the system design stage, or a coding failure, or an omission from the test procedures, I cannot determine.
  • The technology exists to prevent a credit card being inserted into a reader at inappropriate times. This had not been selected at the design stage.
  • The failure to eject any contents under either a fault condition or a reset condition could be considered a design failure.
  • The reputation for swallowing credit cards could indicate a design weakness, or quality control issues during manufacturing, or some combination of both.

Finally

On returning to the car park about an hour and a half later, the technician had just retrieved my credit card, and gave it back to me.

Hyperlinks opening the wrong application?

11 October 2013 by · No Comments · Uncategorized

My Thanks Go To …

My thanks goes to Gail Poulin (Blog: http://poulingail.edublogs.org/, Twitter: @poulingail) for asking a question about something that seemed to be going wrong on a computer.

Background

Gail, others and I were in a Blackboard Collaborate room when she reported that all the hyperlinks were opening OpenOffice for her, rather than taking her web browser there. I was not able to solve this in the time available in the webinar, so we agreed that I would find an answer, and get back to her, and I am using this post to do just that.

The Cause?

It is not possible to be completely confident that I have found the cause until the proposed solution has been tested and been found to be effective. With that disclaimer out of the way, it seems that there is something wrong with something known as “file associations” in her Windows 8 computer. The “http” protocol (don’t worry if that is meaningless to you) was linked to OpenOffice instead of her default web browser.

A Solution?

Gail is running Windows 8, so the steps below are tailored for that environment.

  1. Start Windows 8.
  2. If required, log on.
  3. Press the Windows+W key. The search panel should appear.
  4. Type in the word “default” (without the double-quotes). A list of items should appear.
  5. Click on the”Default Programs” item. A “Default Programs” window should appear.
  6. Click on “Associate a file type or protocol with a program”. A list of file extensions should appear.
  7. Scroll down to the bottom, and look for “URL:HyperText Transfer Protocol” in the description column.
  8. Verify that the “Name” field looks like “OpenOffice” (or possibly “OpenOffice Writer”, or just “Writer”)
  9. Click on that line. It should become selected (i.e. be displayed in blue).
  10. Click on the “Change program” button. A dialogue box should appear.
  11. Click on “Internet Explorer” (or, if your preferred web browser is different, click on that one instead). Wait a few moments, and check that your change has been effected.
  12. If necessary, repeat the above few steps for “URL:HyperText Transfer Protocol with Privacy”.
  13. Close the “Default Programs” window.
  14. Verify correctness of operations.
  15. This procedure is complete.

Firehosed by Professional Development

5 July 2013 by · 7 Comments · Uncategorized

INTRODUCTION

My thanks goes to Rodney Turner (web site http://techyturner.blogspot.com.au/, twitter @techyturner) for prompting me to write this post. He mentioned the word “firehosing” in connection with professional development sessions, and brought into sharp focus something that had been at the back of my mind for some years. I then tweeted firehosingPDwhich provoked two retweets and some jaundiced exchanges about professional development.

THE INSIGHT

Rodney’s comment made me re-evaluate both the professional development (PD) sessions that have been to, as well as those where I had been an observer. What, I wondered, would people remember of being talked at for eight hours in a PD session? A little bit of Internet research came up with a study which can be summarised as learners remember

  • 10 percent of what they read;
  • 20 percent of what they hear;
  • 30 percent of what they see;
  • 50 percent of what they see and hear;
  • 70 percent of what they say; and
  • 90 percent of what they do and say

(Metcalf, T. (1997) Listening to your clients, Life Association News, 92(7) p16 – 18). Adult learning principles indicate that activities in a PD session should as varied as possible. See, for example this article by the Journal of Extension. There is one sentence in that article which is particularly telling: “Their motivation can be blocked by training and education that ignores adult learning principles (Knowles et al., 2005)”.

There is also the question of the amount of information that is presented in any one day of PD. If the PD is properly planned and executed, this would be the same amount of information that you would expect your own adult learners to learn in the same amount of time. From what I have seen for myself, and what the jaundiced exchanges would also indicate, is that this does not happen!

Why do we, who are educators and who should know better, allow this sort of disjunction between when we know to be good practice and what we allow to be done to ourselves? Why are we wasting our time, our presenters’ time, and our administrators’ budgets on this sort of thing? How many people can remember all the relevant details of the first session in a day’s PD by the end of the day?

My gut feeling is that less than 20% of all the relevant information is retained at the end of such a day. To put it into the perspective of personal finances, would you be happy for your garage to charge you five times as much as normal for an ordinary service for your car? No, I though not.

A WAY FORWARD

Enough of this bellyaching on my part.

Rodney described a situation where PD is built into the method of work. There is no “once a year formal PD session”. There is, however, a culture of continuous learning. (As I write, it occurs to me that this mirrors a culture of continuous [self-]improvement.) Just-in-time learning comes to mind here. As an aside, when I have seen Information Technology (IT) specialist come across a novel problem (and given the nature of information technology today, there are plenty of those), the first thing they do is use the Internet to see if somebody has already found a solution. Rodney’s comments made it plain that this just-in-time IT solution can be morphed effectively to suit educators.

A FINAL THOUGHT

What would it take to sell this idea to the relevant decision makers?

Don’t Be Scared, It’s Only Maths!

28 April 2013 by · 2 Comments · Uncategorized

INTRODUCTION

I was co-moderating a webinar a few days ago when the subject of numeracy came up, and I had my usual rant about the teaching thereof. Now, I would like to share my thoughts on some of the challenges that teachers might face when it comes to maths.

THE TEACHER’S OWN UNDERSTANDING.

One of my teachers in kindergarten had a very good understanding of how to teach place value. She made it simple for this six year-old child to see the pattern. She praised correct answers to questions, and fostered my own fascination with patterns. Later teachers also taught the patterns of numeracy, and I was hooked for life. This is evident in both my work and my leisure activities.

Other teachers in my primary schooling demonstrated a poor grasp of not just numeracy, but also of reasoning (the next step up in the field of mathematics). It was this that caused me to rant.

A STUDENT PERSPECTIVE

I have heard two main reasons for why people find maths less than appealing. The first is that “it is all too complicated”. This may be due to the intellectual bias of the learner, but most of the time it seems to come down to the teacher lacking either or both of two key skills: a thorough grasp of the material being taught, and an ability to put it across in such a way that the student can learn. The other reason is that students don’t engage with the subject: they do not see it as being relevant to their lives. Again, this comes down to the teacher: the relevance of numbers in our lives is not communicated.

A PERSONAL RECOLLECTION

I cannot remember a time when I was unable to do simple multiplications in my head, so working out the total cost of three bananas at $2.00 each is trivially easy for me. At the other extreme, I have seen people being totally confused when I have tendered $12.30 for an item costing $7.30 . Having said that, I can share an experience where the real-life relevance of what I was learning was not to become apparent for 20 years.

There is something called “constrained optimisation”, where the basic idea is to make as much money as possible from any given situation, usually some sort of manufacturing. The favourite scenario used by maths teachers seems to be breweries. I can also remember this being used in my own schooling, but I soon forgot about it in the flood of mathematical techniques that I was learning. In terms using of those techniques in the abstract setting of a high school maths class, I was entirely comfortable

It was not until 20 years later that the importance of those mathematical techniques in the human context was to become apparent to me. I was told by my employer that the results of my mathematical labours were saving them around $10 million each year. Had it not been for my own fascination with patterns, I would not have remembered what I had learned 20 years previously.

CONCLUSION

The human cost of innumeracy should not be underestimated. I see it every time I care to look (which is not very often, as I find it distressing). I see innumeracy as being as disabling as illiteracy. If this post is about anything, it is a plea to decision makers to drag the teaching of mathematics up to the level that applies to literacy.

An Essay on Technical Writing

10 March 2013 by · No Comments · Uncategorized

MOTIVE

I have often wondered what technical writing was all about, and my curiosity finally reached the level where I decided to find out.

IN ESSENCE

Technical writing is about the transfer of knowledge and understanding from one person to another.

DISCUSSION

The foregoing definition hides a multitude of details. This post outlines my own understanding of technical writing.

RESEARCH

My first move was to see how other people were describing technical writing. This included a Wikipedia article at http://en.wikipedia.org/wiki/Technical_writer (accessed 10 March 2013), as well as course summaries from four training organisations. While the levels of detail differed in every case, they all had a number of common themes.

Drawing on my own experiences in both education and information technology, I was able to recast those themes in my own terms.

TECHNICAL WRITING IS …

A useful starting point is to identify who is involved in the technical writing process. There are three main groups:

  1. The subject matter expert,
  2. The technical writer,
  3. The people who need to acquire the subject matter expert’s knowledge and understanding (the target audience).

When viewed like this, the technical writer is acting as a conduit between the subject matter expert and the people with the need to know.

This has a number of implications for the technical writer:

  • A good interview technique
  • The ability to record the subject matter expert’s knowledge and understanding accurately
  • A good understanding of aspects of the target audience:
    • existing knowledge and understanding,
    • vocabulary,
    • culture,
    • expectations.
  • A thorough grasp of language
  • A facility to present the knowledge and understanding using words that are readily understood by the target audience (“plain English” if you like)
  • An ability to organise all the material in a logical and coherent fashion
  • The ability to use authoring tools efficiently and effectively, including word processors, web page builders, and image editors
  • A good understanding of the strengths and weaknesses of different communications technologies, and how this impacts on the target audience’s learning experience
  • An ability to work well within the client’s documentation styles and conventions
  • A strong desire to produce a first-class document, this requiring persistence and patience.

With the exception of the first two items, educators who prepare their own delivery materials can be expected to have all of the above. Even so, the ability to read and fully understand a curriculum document is similar to the first item, and consulting colleagues on any of points of concern bears a resemblance to the second item.

HOIST WITH MY OWN PETARD?

I must leave it to others to decide for themselves how well this post meets the requirements listed above. If you are interested in also evaluating my work with images, you might want to critically review this article on managing images.

Zombie code: the ghost that bites you.

3 February 2013 by · 1 Comment · Uncategorized

Acknowledgment

My thanks goes to Julian Sims (web site http://www.bbk.ac.uk/management/our-staff/academics/sims-julian, twitter @juliansims) for prompting me to write this post.

Background

Julian and I had a long and wide-ranging discussion on Twitter about some of the causes of the recent disasters experienced by banks when it came to delivering services to their customers. Examples include the Lloyds Banking Group and Bank of America. This was underpinned by Leo Kelion’s article entitled “Why banks are likely to face more software glitches in 2013” which examined the causes of such events. One of the key phrases in that piece is “dead code was brought back to life”. This is often known as “zombie code”, hence the title of this post. The problem with such zombie code is that it was created for another age – it is much the same as asking a stagecoach driver from 1750 to drive a modern day Ferrari: the result is guaranteed to be a disaster.

Discussion

Julian and I were were tweeting each other about possible causes of zombie code, and one of his tweets “@philhart in the UK Aspergers is labelled ‘learning difficulty’ rather than ‘learning specialty’ – could that be part of the problem?” jolted my thinking out of its usual ruts. My short answer to that question is “No”, but that answer needs justification.

Before I go too far, I should mention that Asperger syndrome covers a range of symptoms, one of which includes “Intense preoccupation with a narrow subject” (Wikipedia, accessed 3 February 2013). It is entirely conceivable that this would manifest itself in the way such an individual would write software. I have seen examples where software writing was done in such a way that it was obvious that the software writer had an intense preoccupation with over-applying a particular design style. It is not obvious to me how the software writer’s style would have been influenced by his educators’ use of the labels “learning difficulty” or “learning specialty”.

Once a piece of software has been written and properly tested, it will continue to do the same thing forever, regardless of whether or not its author had Asperger syndrome. We now need to look at the business context in which this happens. Business rules change over time, and financial products come and go. In particular, a new financial product with a strong resemblance to a previous financial product can arise. The key point here is “a strong resemblance”, meaning that it is not identical. In particular, there is something different, and the piece of software that worked correctly for the old financial product is not guaranteed to work with the new product: it has been resurrected, and has turned into a zombie.

By way of a thought experiment, imagine that “cash account” has been changed into a “ready cash account”, and with a change to at least one of its rules, such as what happens when an attempt it made to go overdrawn. It is a new product, but the decision maker, usually somebody high up the organisational tree, is unaware of its impact on the piece of software that is about to become a zombie. The individual responsible makes the assumption that the old software will work correctly with the new financial product. The behaviour of the piece of software then becomes undefined. At the lowest level, cash could simply disappear – this would be picked up by an internal audit and rectified, and the general public would be none the wiser. At the other extreme, it can cause the whole system to crash, and everybody knows about it.

To the Future

Re-casting Leo’s words, I think it is something that we may need to learn to live with. :(

Save or Save As …

6 December 2012 by · No Comments · Uncategorized

Acknowledgment

My thanks go to Derek McCoy (web site http://mccoyderek.wordpress.com/, twitter @mccoyderek) for bringing my attention to this post entitled “Save or Save As: Should Third Graders Know How Computers Work?”

My reaction to that article can be summed up with with this image:
save or save_as

Background

Working as I do in information technology, I use the tools of the trade. I use files and folders for a variety of purposes, in exactly the same way as a 19th century artisan. I have them organised in such a way that I can find everything that I need easily and efficiently. It is a skill, or perhaps a habit of mind, that is well over 200 years old.

Analysis

Today’s children are growing up in an information age. In terms of learning how to be organised, it is no different to children growing in the technological age that has been with us for well over a century. Today’s teachers have a duty to help their charges learn to function as effectively as possible in their own futures. (Teach not what you were taught yesterday, for their futures belong to them.)

Failure to help today’s children learn such skills amounts to a dereliction of duty.

A Way Forward

It is ludicrous that this situation was allowed to arise in the first place. I suggest that every concerned parent takes this matter up with their relevant educational authority, with the aim of having it fully resolved by the end of 2013.

Recognition of Prior Learning by e-Portfolio

4 October 2012 by · 2 Comments · Uncategorized

Background

When I was working for my (now outdated) Certificate IV Trainer and Assessor (TAA) qualification, I went through the exercise of assessing a portfolio of evidence against a national qualification. Strangely enough, I have never assessed any student’s portfolio of evidence for the same purpose. But I wondered what creating and submitting a portfolio of evidence was like from the student’s point of view. Added to that, I wanted to see if it was possible to submit such a portfolio entirely by electronic means, rather than (as I have seen others doing) submitting three large lever-arch files crammed full of paper.

The short answer is “Yes, e-portfolios can work”. The rest of this post describes a history of my efforts.

A Piece of Educator’s Jargon

There is a process in Australian education known as “Recognition of Prior Learning” (RPL). If somebody submits a portfolio of evidence, often based on their experience in the work place, to a Registered Training Organisation (RTO), and the RTO assesses that the portfolio demonstrates competence for the award claimed, then the RTO must award the submitter an appropriate certificate.

Subject Area

My subject area was information technology. More specifically, it was Certificate IV in Programming.

The Production Process

Following guidance others who work a lot with the RPL process, I wrote a number of web pages describing my work experiences, and set about matching those experiences against the specific “Performance Criteria” contained in the Units of Competency that constitute the award. Just as I was about to find an RTO that would accept my portfolio, the Certificate was changed, which meant a major overhaul of my portfolio. It will come as no surprise that I found doing the overhaul rather irksome, but at least it meant that the qualification would be valid for rather longer than otherwise.

Structure of the Portfolio

The portfolio was designed with the following objectives:

  • Navigability: it had to be easy for assessors to move their way around the portfolio
  • Adequacy of evidence: the evidence presented needed to be absolutely convincing
  • Entirely electronic

The result was a web site stored on a CD. It contained the following items:

  • A front page, containing links to the rest of the portfolio
  • A guide to the portfolio: how it was organised, with suggestions to assessors as to how they might like to use it
  • An “evidence matrix”, containing exactly one link for each Unit of Competency
  • For each Unit of Competency, a listing of all the Performance Criteria, along with links into the rest of the portfolio showing how each Performance Criterion was met
  • A listing of each of the work place experiences

The portfolio contained a mixture of text, pictures, screen shots, movies and links to external web sites.

I regarded both the evidence matrix and listings of the Performance Criteria for each Unit of Competency as being crucial to the organisation of the portfolio. It allowed me to check for completeness of evidence prior to submission, and it also afforded assessors a means to do their work easily and efficiently.

A Side Issue

As an educator, I assess student work against Units of Competency, and I do so quite ruthlessly. If there is a requirement for something to be demonstrated, but it is not demonstrated by the student, then I am required to not sign off on the award. As I was digging through one of the Units of Competency (ICAA5154B), I came across two things that I did not immediately recognise (Oikos, SOCCA). After doing some research on the Internet, I discovered that they were both projects that had ceased by 1997, and so could no longer be considered relevant. I approached Innovation and Business Skills Australia about this, and was told, in effect, that they can be ignored for the purposes of assessment. This was in stark contrast to what I was taught when I undertook my TAA training. This, and other issues with other Units of Competency, has left me wondering about how well Units of Competency relate to the needs of such a rapidly evolving industry.

Finding an RTO

There are a number of RTOs near where I live, any one of which could have assessed my portfolio. The first one that I approached kept on passing me from person to person, and never returned my telephone messages. This carried on for weeks. The second responded on the same day that I approached them, and I was enrolled on an information session for RPL candidates two days later.

Feedback from the Assessors

When I attended the information session, I handed in a CD with a copy of my portfolio as it then was, this with the purposes of establishing whether or not the assessors might be happy with it as a means of proceeding. In my view, the contents of that CD could not in any way be considered as being fit for assessment: almost half the evidence matrix was missing, and there was a major error in one the work place experience files. Nevertheless, the assessors concluded that I “was operating at a level far higher than [the] Certificate IV level” (their words), though they did not tell me this until much later. Being educators, and hence rushed off their feet, it can be argued that going through that version of the portfolio thoroughly would not have been a legitimate use of their time.

The assessors needed to check that the portfolio was indeed my own work. They checked with one of my clients that I performed the work claimed in the portfolio. They had also encountered another RPL candidate whose portfolio was not his own work (in other words, a fraudulent candidate), and they needed to check that I was indeed the author of the portfolio. We arranged to meet. It was at this meeting that I handed over a CD containing a complete and correct portfolio of evidence. They also revealed that the fraudulent candidate did not even understand the questions that he was being asked at the equivalent meeting.

The assessors deliver learning in a Microsoft context. I work an an open source context. This might have presented something of an issue when it came to a practical demonstration of my own competence. I required of my assessors that I perform my demonstration in my own context, to which they were unhesitatingly agreeable. As a result, I needed to use a student computer in a sandpit setting so that I could load on to it everything that I required. Fortunately, such computers were available. (For the uninformed, most student computers are locked down so hard this sort of thing is quite impossible on them.) The practical demonstration went flawlessly.

The meeting continued after the practical where we chatted about both education and information technology. I was asked for my motive in going through this RPL process, and I duly explained. They also invited me to go for a Diploma based on the evidence that they had seen on the initial CD.

And returning to the theme of having an entirely electronic portfolio, the assessors said that it was by far the best that they had seen, and that it was very easy to navigate. I had achieved my objective.

Update

In a similar fashion, I submitted a CD for the Diploma of Software Development a few weeks later. This was assessed as demonstrating competence without any further work needed on my part.

To the Future

There is a Teachers Guide on the Use of ePortfolios in Education by Med Kharbach (twitter: @medkh9). My own portfolios sit at the “Portfolio as Showcase (Product)” end of the spectrum. They were created using a simple text editor and basic image editing software, this coupled with a good grasp of HTML and CSS. For classroom usage, I would suggest the tools pointed at by Med’s post.
