Welcome. We are Aarón Alzola Romero and Elton Barker, from the Open University's Department of Classical Studies. This blog is part of a broader research project exploring the uses (and abuses) of mobile learning in the Arts. Our aim is to examine mobile learning applications, assess their strengths and weaknesses (in terms of user interaction, contribution to learning outcomes, cost and popularity), identify areas of opportunity and challenges in their future implementation and assess the impact that mobile learning solutions have on the delivery of Arts courses.

Whitewashing the ML fence

One of the reasons behind some of the scepticism towards ML is the popular perception that this form of education leads to an over-reliance on the very resources that make it possible. Students, some argue, are reaching a stage where they aren't able to achieve anything for themselves without the use of their smartphone or tablet.


On one end of the spectrum, there are those who argue with horror that modern pupils do not bother to learn facts any more, because they can simply google anything up on the spot if and when they need the information. The implications are that ML students don't really know anything themselves -- they just know where to find someone (usually in the form of a digital resource) who does know.

On the other end of the spectrum, there are those who don't see a problem with the idea of not learning facts. We don't memorise all our friends' phone number or all the times and venues of the meetings we need to attend this month (we simply use a calendar or a diary to remind us), so why should education be any different?

When the problem is approached from a pedagogical point of view, most people take a middle ground. In many ways, developments in ML do not challenge modern attitudes to teaching -- in fact, they complement approaches to pedagogy that were already well established way before tablets and mobile phones were around.

In the 1960s, there was a radical change in instruction strategy: a shift from test-driven transmission teaching (conceived as a top-down, mental transfusion from the teacher to the pupil) to exploratory, hands-on and problem-centred approaches. The maxim became: learning is not the same as memorising. Encouraging students to develop useful learning skills became more important than hammering raw data into their brains. Aspects like observation, critical thinking and communication started making their way to the top of the curriculum.

This led to decades of debate among educational researchers. People like Paolo Friere and John Dewey argued against rote learning and for an active, dialectical, student-centred approach, while E.D. Hirsch, Jr. argued against what he termed their naturalist perspectives and for the core root of facts necessary for domain specific knowledge. Today, most teachers see these apparently conflicting positions as two sides of the same coin -- complementary aspects of the learning process. Developing knowledge is still an important part of education, but learning to develop that knowledge and what to do with it (i.e. the 4 Cs -- critical thinking, creative thinking, communicating, and collaborating) is also crucial. This aspect of education is what educational researchers call 'learning skills'.


As well as providing access to online repositories full of facts, ML resources allow students to develop a broad range of transferable learning skills as they classify, analyse and evaluate content (assessing the reliability of particular online resources, collating useful data from a range of platforms and learning how to adequately reference online and offline materials); they participate in problem solving activities; imagine, design and create their own resources; and collaborate with groups of people, setting goals and exercising team building skills.


Although ML is a very young field in education, its underlying principles are  not a radical departure from the teaching methods that educational researchers have been developing since the 1960s. Contrary to popular perception, in many ways ML complements and extends a long established pedagogical tradition.

Galileo and ML

Galileo is a global positioning system that is currently being deployed by the European Space Agency. It's made up of a network of satellites which will complement and integrate with the functionality of existing international positioning systems. Despite a fair amount of funding headaches (and a little tantrum thrown in by the USA), the first Galileo satellite was successfully launched in 2005. The system is not expected to be fully operative until around about 2015.

Compared to current global positioning systems, Galileo introduces a few snazzy features. However, the feature that really stands out (in terms of its implications for ML) is its level of precision. Galileo will be accurate down to the metre range. Current general-purpose GPS receivers have an accuracy range of about 10-20 metres (or even worse at high altitudes). This means that, in practice, they only work as navigation systems for large, open areas. For example, integrated with a ML smartphone app, these systems are able to tell us where the nearest open museum is, what building we are looking at, or what part of town we are in.

With Galileo, provided a clear satellite signal is available, mobile devices will be able to detect which display case museum visitors are standing by (and provide personalised content at point of consumption); generate diagrams showing how people move around the gallery on a metre-by-metre basis and how long they spend interacting with each individual display (facilitating user data analysis for curators and events organisers); they could allow participants in educational crowdsourcing projects to geotag locations / learning resources / interesting features in libraries, archaeological sites, art galleries, etc. with a high level of precision (making it easy for other users to go back to that precise spot, find the resource and benefit from it); they could provide a new set of tools for blind students to engage with educational resources spatially in a classroom or lecture hall.

By reducing the error margin of existing geolocation systems from 20 metres to <1 metre, Galileo could open a massive range of new options for teachers and students in mobile learning.

Mobiles in numbers


A few quick stats about the current state of the mobile industry:

-The global mobile phone user base is growing exponentially
There are approximately 6 billion mobile phone subscribers in the world. It took 20 years to reach the first billion mobile phone users, but only 15 months to reach the last billion users.

-Most mobile phone users do NOT speak English
Many ML resources are created with Western English speakers in mind, but these users account for less than 10% of the global user base. The fastest growing world regions in terms of mobile phone usage are China and India (which, together, make up 30% of the global user base).

-The amount of internet resources accessed through mobile devices is also growing exponentially.
70% of all phones sold in the USA are internet-enabled smartphones (this could reach 90% by X-Mas). Less than 50% of all mobile traffic is voice. 60% of all Twitter traffic and 70% of all Pandora traffic come from mobile phones.

-The mobile phone sector is highly volatile.
Around about a year ago, the word ‘iPhone’ was synonymous with smartphone. In fact, things were looking quite rosy for Apple – the iOS market share had grown by a whopping 115% in 2011. Today, Android has more than doubled the smartphone user base of iOS. Half a million Android handsets are activated every day. Blackberry, the brand that epitomised flashy corporate smartphones merely four years ago, is now looking at a global market share of potentially less than 5% next year.

 What does this tell us? 

  • Most internet resources / services that are not adequately accessible through mobile devices could risk disappearing in the medium / long term. 

  • The global mobile phone user base is enormous, but cultural and linguistic differences make it difficult to create resources that have a global appeal.

  • The demand for mobile resources, including ML, is likely to grow exponentially in the short and medium term.


  • The high level of volatility in the mobile industry means that platform-specific resources (e.g. apps) could have a relatively short shelf-life and limited scalability. Web-based mobile resources might be a more attractive prospect for long-term projects.

The battle of the ages

The Nintendo 3DS console was introduced to the Louvre last March with much fanfare. You might think that this games console is more likely to be associated with mustachioed Italian plumbers than the Venus of Milo. Well, on this occasion it is conceived as an audio guide on steroids. It provides museum visitors with interactive maps of the museum, suggests themed itineraries for different visitor profiles, complements the displays with hundreds of commentaries recorded in seven different languages, provides high resolution images of paintings that may be difficult to look at closely in the galleries (like the Mona Lisa) and even generates 3D reconstructions of statues. According to Agnes Alfandri, Louvre’s head of multimedia, less than 4% of visitors were using the old audio guide, so it was imperative to galvanise the system in order to keep up with the times.

Interestingly, user feedback suggests that the Nintendo 3DS guide may have received mixed reactions. In fact, it seems to have drawn a wedge between two group categories: the under-thirties (approximately 1/3 of all visitors), who have responded quite positively to the new system, and the over-thirties (approximately 2/3 of all visitors), who appear to be somewhat less enthralled by the entire thing.

This battle of the ages is being fought on three fronts:

1. Games consoles in a museum
    • Under-thirties: many in this category see museums as intimidating, alien environments. Games consoles make museums appear less serious, more approachable and engaging.
    • Over-thirties: the idea of using games consoles in a museum is about as appropriate as bringing a vuvuzela to a funeral.
2. Ease of use
    • Under-thirties: The console and its interface are very intuitive and easy to use.
    • Over-thirties: The console and its interface are very alien and difficult to use.
3. Eye candy
    • Under-thirties: The 3D reconstructions of artefacts are cool.
    • Over-thirties: I’m standing in front of the actual statue. What is the point?
Of course, these are gross generalisations, concealing an even broader and more complex range of reactions to the system. However, the initial user feedback does highlight two important aspects about ML and some of the challenges faced in its implementation:

1. ML (and digital learning resources in general) have the capacity to reach a broad user base, but these users have very different needs, tastes and priorities.

2. The digital divide is not just about being able to access ICT, it’s also about developing the skills and knowledge required to use it efficiently.
