What Do ICTs Represent: A Bridge To Knowledge Or A New Exclusion Factor?

19 Iulie 2004
The new technologies obviously offer new, interesting opportunities for access to knowledge. Their application may also however become a new exclusion factor.
This paper sets out to offer a first examination of this issue, based on articles published on the elearningeuropa.info portal.

A brief theoretical note may prove useful to focus the question. According to Information Theory, knowledge tends to become concentrated in itself. Richer structures are able to accumulate new information with ease. In contrast however, “info-poor” structures tend to remain so. In other words, the distance between those who know a lot and those who know little is tending to grow because the former gather information faster than the latter. The propensity of information to become accumulated into increasingly complex structures seems to be a general tendency of all systems, from human societies to ecosystems.

This context provides the setting for the two basic academic visions that the new technologies invoke in contemporary societies:

1. The new technologies may constitute another exclusion factor to be added to the classics (age, poverty, illiteracy and so on). ICTs may therefore aggravate pre-existing problems.

2. The new technologies may help overcome some “traditional” exclusion, fostering as they do new methods of learning, and can especially benefit social groups distanced from traditional education.

Both visions are clearly contrasting. Yet both are probably true. What factors determine the predomination of one force or the other in one particular social group or context?

Do the information and communication technologies constitute a new exclusion factor?

Some of the articles published on the elearningeuropa.info will help us explore to what extent the new technologies may represent an exclusion factor.

The article, Obstacles to Older People using Computers, by Melanie Lewin, offers an interesting perspective on the problems affecting the elderly. Senior citizens make up a perfect example of the exclusion phenomena as they concentrate a large number of exclusion factors: their advanced age is added to their poverty (the elderly generally exist on a low income); they suffer disabilities (the severity of physical problems increases with age); their educational level (usually lower than average); elements related to gender (there are many more elderly women than men), and so on.

To date, the new technologies have acted as a factor of exclusion rather than one of inclusion in this context. Senior citizens have little or no access to the information society and this intensifies their remaining at the margin of the social system. In Catalonia, for example, 71.7% of young people between the ages of 15 and 19 are Internet users, a percentage that falls to 4.7% for people aged from 60 to 64, according to the study The Net Society in Catalonia, published in 2002.

Though the passage of time will tend to improve these results it is obvious that in our ageing Western societies an extremely high proportion of people have no access to the ever-increasing number of services available through the Internet. Worse still is the fact that many senior citizens show no interest whatsoever in the virtual world, seeing the new technologies as “not for them”, and thus tend towards their own self-exclusion, according to the thesis of the French sociologist Philippe Breton (see the article, “Old People Feel Excluded from New Technologies”.

Much remains to be done to redress this situation and in this respect the "Report on Special Education in Europe" provides a useful focus. When educational needs are highly specific and complex, e-learning systems should be adapted to certain specific contexts and thus introduce the flexibility that pupils lack. They should, above all however, also form part of a global, coherent educational approach. There is little point offering a few classes to senior citizens, for example, if later they have nobody to answer the endless number of little doubts that the day-to-day handling of computers raises for a novice in the field. An education and training service should be provided which is especially adapted to extremely well-defined areas and characteristics.

According to the "Charter for Digital and Social Inclusion", the digital divide, “is a multidimensional phenomenon which includes barriers that are highly diverse in nature. It is the cause of great concern that some of these are in essence psychological and must therefore be approached with an educational strategy. Others, involving a lack of confidence or motivation, are attributable to the user, but there are also barriers in the production of e-learning systems, such as the development of excessively formal systems and non-adapted technologies, the lack of meaningful context and the use of generalist methodologies that fail to pay the necessary attention to cultural and social contexts.”

Are the new technologies an inclusion factor?

On the other hand, some reports have detected an interesting potential for inclusion in the new technologies. A study carried out in Spain, for example, suggests that pupils with least motivation and the worst grades are those who experience greatest improvement when the computer and digital teaching materials are introduced into their education (see the article, “An experimental study on the impact of the computer in the classroom”). According to this line of argument, the new technologies can play a “redistributor” role in the dissemination of information by stimulating the rhythm of information acquisition of those who know less and bringing it closer to that of those who know more. This is the case because the new technologies exert influence in two essential aspects: motivation and learning processes.

With regard to motivation, the analysis carried out by Wendy Jones in her article, "The BBC and e-learning" is highly revealing. The wide range of resources and platforms made available by the BBC (interactive television, mobile telephony, websites and so on) has enabled the Corporation to reach segments of the public usually highly resistant to formal learning proposals. As Jones explains, “The e-learning environment created by these new technologies can break down barriers to learning, particularly among the young. For many of this “screen generation”, new technology is inherently attractive and ICT is linked to leisure.” The migration to e-learning from computer games or interactive TV may prove to be relatively simple.

As regards learning processes, obviously the new technologies bring into play a certain degree of diversity in cognitive processes, reason for which it is easier for a multimedia system to be adapted to individual learning styles. This will attract a wider variety of pupils and may lead to more uniform access to knowledge. Furthermore, as Professor Tony Bates emphasises, “multimedia systems allow a richer mental construction than classical linear text.”

Some characteristics of the new technologies seem to facilitate their inclusive role. Many e-learning projects work in informal environments and introduce certain leisure-based aspects: participative models are often introduced which are based on games and simulations and the diversity of resources (texts, animation, videos and so on) stimulates diverse styles of learning. But to be able to play out their inclusive role it is necessary for access to the new technologies to be produced in the right environment, an environment which excluded collectives obviously lack.

Conclusion

In certain contexts it seems clear that the new technologies may help distribute knowledge better. Information will continue its tendency to accumulate in itself, but ICTs can help in the flow of information towards the less fortunate. It is also highly likely that they help homogenize learning rhythms.

For this to occur however, minimum conditions of access must be available from which the ICTs can help break down the barrier of lack of motivation and previous information. When the problem of exclusion is serious and the minimum conditions of access to computer systems inexistent, the new technologies only exacerbate the existing problem by adding a further element of exclusion.

How can we avoid the negative side of ICTs and strengthen their positive aspects? The answer to this question lies in guaranteeing equality in their conditions of access, an issue far more related to media literacy than to access to technology. We shall be witnesses in the coming years to a multitude of projects along these lines. In fact, there are now so many initiatives that the e-Learning for e-Inclusion project has developed its own method of classification: a Digital Library containing a great number of projects, classified by the type of inclusion problem and the solution they provide.

The number of projects whose aim is to achieve digital inclusion will rise exponentially over the next few years. The challenge will consist in learning enough from them to be able to design a structured framework of knowledge. Research into exclusion factors must be energetically promoted, as well as that into the characteristics of the different social groups that are excluded. Bibliography:

Adult Learning and ICT

29 Iunie 2004
"I grow old learning something new every day" (Solon, c.639BC - c.559BC)

"We are all adult learners. Most of us have learned a great deal more out of school than in it." (Laurent A Daloz, Effective teaching and mentoring,1986, ch.1)
Although classes in the University of Strathclyde’s Extension Programme, run by the Centre for Lifelong Learning are "open to all, regardless of age or previous educational experience" most attendees are adults, who have completed secondary education.

A key feature of adult learners is that, in general, they attend classes voluntarily, unlike the Shakespearean schoolboy, "creeping like snail, unwillingly to school". That said, another characteristic of adult learners is that they have an agenda, a reason to be there. This differs from one person to another. Some researchers suggest that where the motivation is professional or work advancement, attendance cannot be said to be truly voluntary. However, a general distinction can be made between those attending school because it is compulsory or pursuing formal academic and vocational qualifications on one hand, and the majority of adult learners on the other.

The way in which adults learn

It is only relatively recently - from the 1970s onwards - that attention has been paid to the way in which adults learn as distinct from the way children learn. Malcolm Knowles cites four key differences.

· self-concept ; adults are less likely to ’brush off’ failure;
· experience : adults who cannot master a new skill suffer a lack of self-esteem;
· readiness: children are more willing and able to learn and accept new ideas;
· time : children are unafraid of failure as they feel they can always learn later; adults are less likely to feel like this.

Subsequent researchers identified other factors affecting the adult learner:

· Scheduling problems
· Lack of time and money
· Family and job responsibilities
· Transport problems

On the other hand, research also suggests that adults compensate for outdated knowledge by working harder, find it easier to incorporate new knowledge into existing knowledge, are more highly motivated and have a clearer purpose. Some writers suggest that older learners can compensate for being slower in some psychomotor skills by being more accurate and less likely to resort to trial and error. A corollary of taking errors personally and thus lowering self-esteem is that adults take fewer risks, relying on tried and tested methods.

Much of this applies to any class of adults, and it can be straightforward to deal with some issues. For example, open-ended sessions benefit those who do not want to miss their ‘bus or train home.

It could be argued that teaching computer skills to adults is a special case. Older learners are faced with a subject which may not have existed when they were undertaking school or post-school education. At worst, this can manifest itself as "computerphobia" or "communication apprehension". Brosnan and Davidson (The psychologist,vol. 7, 2, 1994, pages 73-8) looked at evidence which suggested that between a quarter and a third of all people are computerphobic. However, surveys suggest that computer ownership amongst older people (55+) is increasing - the so-called "silver surfers" - and that the average age of Internet users is therefore rising.

On my courses, familiarity with the computer, both hardware and software, varied amongst the participants. This confirms the findings of a survey by Clyde and Klobas of Internet trainees based in Iceland. The opening class is a good time to check if students are familiar with right-clicking, minimising windows, etc.

Motivations to learn ICT

Icebreakers in week 1 give each student a chance to say why he or she is there. Some reasons were obvious:

· retired people seeking a new interest (or wanting to keep up with their grand-children!);

Others were less so:

· need to use IT skills at work but lacked training opportunities;
· working towards European Computer Driving License;
· wanted to use Internet to plan and book holiday

With retired people, the motivation was often general - a desire to find out about new technology - but sometimes quite specific. One retired gentleman in my Internet class was also attending classes in JAVA, and wanted to find and download applets from the Web. A former English lecturer was interested in newsgroups and Web sources on his favourite authors. He later returned to my HTML class, and began building his own website. Another class member wanted to research family history, particularly connections with the Boston area. Within the overall plan for the class then, it had to be possible to cater for individual and quite specific interests, without neglecting those whose interests are more general. Learning to use the Internet can be a useful starting point for the acquisition of general computer skills.

Teaching about the Internet should establish general principles about searching, but also pass on useful information such as what to do about spam, or perhaps what not to do. Students should become aware that any information on the ’Net has to be approached with a degree of caution. Anyone who uses the Internet as a source of information has to learn to do so critically. Books on library shelves, articles in a journal, have normally gone through a selection or editorial process, which is transparent to the user. Such quality control does not necessarily apply to Internet sources.

Even those comfortable with the general skills of personal computing can find the Internet daunting. Searching for files on hard disk, floppy or CD-ROM is relatively uncomplicated. Using the Internet to find and download information is less so. Response times vary, error messages can be difficult to understand, and the lack of a coherent structure to the Internet is confusing, like having to use the telephone system without a phone book.

As one of "30 things we know for sure about adult learning", Ron and Susan Zemke say:

"…straightforward how-to is the preferred content orientation. Adults cite a need for application and how-to information as the prime motivation for beginning a learning project" (Innovation Abstracts Vol VI, No 8, March 9, 1984)

Applying that to teaching about the Internet means a minimum of formal lecturing and a strategy of using practical, hands-on exercises where possible. Instead of talking about truncating URLs, which generate error messages, let students point the browser at a problem URL and gradually truncate it until it works. Get them to e-mail a bogus address and then look at the resulting error message rather than just describe it. A student mistake such as typing one ’/’ instead of two in a URL, that can be used to reinforce correct practice. Once again, it is important that the students develop understanding and skills which will be relevant and lasting.

"We have to abandon the idea that schooling is something restricted to youth. How can it be, in a world where half the things a man knows at 20 are no longer true at 40 -- and half the things he knows at 40 hadn’t been discovered when he was 20?" (Clarke, Arthur C.

Commercial Cybercafés: A Useful Weapon Against the ‘Digital Divide’?

08 Iunie 2004
In some countries of the developing world, cybercafés are by far the main way to connect to the Internet and to interact with computers. This is the starting point of this interesting analysis on the role of Internet in less developed countries.
Internet use is rapidly spreading to the developing world, bringing connectivity to individuals and groups and promoting the transformation of communities on a global scale. Yet only a small fraction of the people in the developing world can afford to have home connection to the Internet. A dial-up connection, the way most people connect, implies to have a fixed telephone at home, to buy hardware and software equipment and to pay the monthly telephone and Internet charges. This way of connecting to the Internet is evidently not suited for all people, as most people in the world do not have the resources to afford all this.

Within this difficult context, collective access is the only alternative that can give Internet connectivity to the masses. Places for collective access have been growing steadily in the cities of the developing world, established by three main stakeholders: (1) governments, (2) NGOs, activists and the development community, and (3) the private sector.

1. Governments’ Programmes. Universal access to the Internet is acknowledged by most governments as an important step towards the progress of their nations. Programmes have been created with that purpose, sometimes under an umbrella programme, sometimes as fragmented small scope policies addressed to different target groups (students, low-income groups, isolated communities). However, developing countries’ governments have scarce resources and urgent problems, so they have difficulties to properly fund universal access programmes, which generally end as good intentions, or having modest goals and target populations. Further, governments’ telecentres may have social goals or not. Many public programmes have been addressed to simply establish public access centres while expanding the geographic coverage of public telephony and Internet in their national territories.

2. Socially Oriented Projects. NGOs, activists and other non-profit institutions have established ‘telecentres’ or public access centres with socially oriented goals. These have been set up in developing countries thanks to the support of the international donor agencies, which see in them the best feasible model for providing Internet access in rural and poor areas. Telecentres do not consider themselves as providers of universal access, they rather provide training on new technologies, youth and community gathering, and promote local economic activities through support to micro-enterprises and associations. Although the telecentre community is very dynamic and highly networked, there are no large numbers of this type of collective access points, which also suffer from problems of economic sustainability.

3. Demand-oriented Cybercafés. The commercial type of public access centres is, for the users, the most popular of the three types. Cybercafés are flourishing in places of concentration of activities in cities of the developing world. Cybercafés have existed in the large cities almost since the commercial introduction of Internet in cities. Originally, they were addressed to the demand of tourists or businessmen, and located in business and commercial districts. However, the new trend is another type of cybercafé run by local entrepreneurs addressing the demand of those who cannot afford home connection. Therefore, the prices per hour in this new type are much cheaper and tend to decrease when new businesses open their doors in the vicinity. But cybercafés have no social pretensions; they are simply the fruit of thousands of individual business initiatives of small entrepreneurs. Their function is to provide connectivity to the customers that pay for it, and as such, they are highly demand-oriented.

The example of Peru: the cybercafé as a new urban facility

In some countries of the developing world, cybercafés are by far the main way to connect to the Internet and to interact with computers. One of these countries is Peru, where more than 80 percent of Internet users connect from collective places. The effect of the popularity of cybercafés is visible in the Peruvian society. They have become a new urban facility at neighbourhood level. The use of computers and Internet has become common by school and university students. Peruvian have changed their recreation activities and since 2002 the visit to the cybercafé has become the first recreation activity. Peruvians are much better communicated with their relatives abroad than before, which has partly contributed to increase the level of remittances to the country. At city level, cybercafés are offering different urban services which have been systematically denied to poor neighbourhoods. Libraries, post-offices, recreation facilities, youth centres, training centres, etc. are now present and combined in the multiple services offered by cybercafés (Fernández-Maldonado, 2003). All this has happened without any support from the state, and in a country that has more than 50 percent of its population living in poverty.

The wide availability of affordable cybercafés in cities of Peru has developed a local Internet culture which is especially clear with youth and students of all sectors of society. This has already called the attention of outsiders, since Peruvian cybercafés have removed the first barrier that lower-income groups have to connect to the Internet. The experience in Peru poses a series of questions, from which an important one is: are commercial cybercafés a good alternative to tackle the digital divide in developing countries?

The nature of the Digital Divide: from access to the networks to the ‘effective use’ of ICT

But the answer to this question is not straightforward. There are multiple debates going on in the academic and practitioners fields that need to be spelled out to understand the context. To begin with, the very existence of the digital divide is a matter of debate. In developing countries, the ‘digital’ divide is just another symptom of the social and economic divide among rich and poor and, as such, not a very useful category. To alleviate it requires structural solutions. To solve the digital divide would be then, a matter of development.

Another important debate is on the nature of the digital divide. The initial conceptualisation of the digital divide as a difference in access to the networks has given room to a more comprehensive concept that encompasses the notion of ‘effective use’. The idea behind this is to redirect the resources to fight the digital divide from simple access towards more sensible strategies that provide more visible benefits to users. Because it is obvious that large software corporations and telecommunications firms are the great winners from the increased global connectivity.

But the notion of effective use, while useful in rich countries needs some attention in the context of developing countries. What is ‘effective use’? Michael Gurstein defines it as “The capacity and opportunity to successfully integrate ICTs into the accomplishment of self or collaboratively identified goals.” (2003: 8). If effective use is a matter of the users, individually or collectively, it is them who have to decide if they are getting an ‘effective use’.

The importance of the Internet in the ‘Global South’

When users in developing countries, and especially young groups, are consulted about the significance of Internet use in their lives, they all answer straightforwardly, enthusiastically and positively. This differs greatly with responses in rich countries, where access to the networks, and the new uses it brings, may be experienced as a threat to the familiar ways of doing things, especially in work environments. In affluent countries access to the new technologies is a matter of personal election; in disadvantaged regions it is a new resource that generally implies an improvement of daily life.

Regarding communications, if in the developed world the Internet complements other telecommunication media such as telegraph, traditional mail, fax, and local or long-distance telephone, in the developing world access to the Internet provides new possibilities for communication among peoples who previously could not contact others who were distant from them, because of the absence, scarcity, inefficiency, or unaffordability of traditional communication services.

Regarding information, if in the developed world the Internet complements familiar sources of written information as newspapers, books, magazines, bulletins, brochures, data bases, research papers, in the developing world access to the Internet provides new possibilities for information for peoples who previously could not afford a book, attend a library, read the news or consult an encyclopedia.

Common sense tells us that access per se is not an end in itself. But for the people in the global South, and especially for young users, access to Internet is making a big difference from their previous situation, a fact which is sometimes difficult to perceive for outsiders, or those interested in measuring economic impacts. In the developing world Internet is more a cultural than an economic phenomenon, and its use is rapidly transforming communities in unprecedented ways.

Another related debate goes on regarding the observed uses of commercial cybercafés in cities of the developing world. Several surveys and observations point out that the use of Internet in cybercafés is highly linked to communication and entertainment purposes, while didactic and economic uses are not as popular as the first. The public that attends cybercafés is mostly young people and students, who enjoy the possibilities to communicate and chat with their peers. The example of the success of text messaging in countries of the North suggests that young people’s strong ‘communication need’ is an age-related phenomenon.

But it becomes difficult to separate communication, work, entertainment and learning while using the Internet, because one of its singularities is precisely its multifunctionality. Further, almost no ethnographic studies have been yet carried on to see the impact of cybercafés on people’s lives. On the other hand, the great enthusiasm of young users towards the Internet as a window to the world is not taken into account. If we ask the users, they generally express the importance they give to improving their computer skills and training to get more chances in the highly difficult employment market. As in the previous debate, the scepticism towards Internet use in cybercafés suggests the higher importance assigned to economic productivity than to the daily life concerns of the users. The social implications of the Internet are not straightforward (DiMaggio et al., 2001).

Challenging the logic of the Digital Divide discussion

Recently, two economists from the World Bank have challenged the logic of the main arguments on the digital divide discussion, and provoked a lively discussion within academics and practitioners circles. Carsten Fink and Charles J. Kenny (2004) have point out that measuring absolute differences is quite a different affair than measuring relative differences in access to ICTs. They state that, given the presence of collective ways to access telephone and Internet services in developing countries, per head measurements do not constitute a good indicator of diffusion.

A better indicator, which gives idea of the relative importance attached to ICTs by users, is their per-income availability. On this indicator, low- and middle–income countries are ahead of affluent countries, a fact which becomes more surprising given the worsening of income inequality between the developed and developing countries during the last decades. This suggests that developing countries have found their ways to “catch up digitally”. Fink and Kenny finally state that the divide between rich and poor countries is closing instead of growing and that there are more digital opportunities than divides.

These and other related debates give an indication of the importance of the topic for academics, practitioners, NGOs, the development community, and policy makers. Perhaps is useful to remind that, despite its rapid diffusion, global use of the Internet is still in its infancy. The rapid pace of technological advances in ICTs may change the present picture in unforeseen ways. In the meantime, it is necessary to give careful attention to the digital problems and opportunities of the most disadvantaged groups. References:

How to Remove the Major Obstacle of Learning: poor usability

12 Martie 2004
Before starting to write this article, we checked if there was anything written about usability in Finnish or English in the elearningeuropa.info site and found some articles about this issue.
Now, at the latest, it is time to act for rooting out the usability problems related to nearly every aspect of virtual learning environments (VLEs):

· relevance and form of the content;
· navigational aids;
· activation and motivation of the students;
· guidance for studying.

Several recent publications of e-learning report usability problems in the current VLEs. The problems include, for example, unnecessary features, which are either rarely used or not used at all (Beasley&Smyth 2003), lack of navigational freedom affecting the user’s feeling of control (Armitage et al. 2003) and difficulties in identifying content (Lindh and Soames 2003). The environment may also be so difficult to use, that it causes deep dissatisfaction in the students (Kent 2003) or even withdrawals from the course (Jones et al 2003).

The VLE being highly technical or artistic does not matter, if the usability of the environment is poor. The lack of good usability makes students avoid using the environment or concentrate on irrelevant issues instead the content. One solution for achieving a VLE with good usability is to design the VLE using User Centred Design (UCD) approach.

Usability and user centred design

Usability is defined as effectiveness, efficiency and satisfaction (ISO 9241-11) which, in case of a learning environment, means:
· Are the users able to use the VLE for studying purposes?
· Is the learning with the VLE efficient, for example, is the user able to access the information and adapt the content?
· Is the interaction between the user and VLE smooth and comfortable?

Problems mostly occur, because learning environments are not planned and tested their target user group. In the beginning of the design process of a learning environment, the targeted user group and the environment of use, the context, should be defined. If a defined learning environment development method is used, this phase is usually included in the design process. However, the following phase is often somewhat, or even totally, neglected. During the design and implementation, the learning environment should be iteratively tested with prototypes within the targeted user group.

The motivation for usability studies during the design and implementation phases, in addition to better learnability, is money. Like in every other software engineering project, also in case of learning environments:
The later the change is made the more it costs in terms of labour, time and customer satisfaction. (Boehm 1987)

Case example

Virtual learning environment concerning safety at work, Virtu, was designed and implemented in co-operation between two institutes, Software Systems and Occupational Safety Engineering, in Tampere University of Technology using the UCD approach (Ihamäki and Vilpola 2003). In the beginning of the case Virtu, two user groups were defined; students at the university and workers in industry. The first paper prototype was tested within both groups and the most significant finding was that the same content was not appropriate for both user groups. As a result, two separate contents were made for students and industrial workers. This decision also affected the structure of Virtu, but the change was easy to make in requirements specification (Figure 1).



Figure 1. Project activities and usability actions in Virtu´s development.



Development of Virtu had six usability actions:
· ISO 13407 Human centred design processes for interactive systems (ISO 1999)
· Interviews
· Paper prototype and its testing
· Functional prototype and its testing
· Heuristic evaluation
· Iterative design

According to the standard ISO 13407, context of use and user and organisational requirements were specified using stakeholder interviews. From the basis of requirement specification, a paper prototype was made and tested within end users. Changes ware made to the requirements specification according to the test results. Next prototype was implemented in the design and implementation phase and it was tested again within the end users. Comments received from the tests were adapted to the implementation. Testing and implementation were iterated until no big changes occurred. In addition to the end user testing, a usability expert evaluated Virtu. In this evaluation the expert used Jakob Nielsen´s heuristics (Nielsen 1994).

How to ensure usability of the VLE

Usability is a key issue what comes to teaching and studying using VLEs. There is no way you can add usability in a ready-made VLE (of course the current VLEs can be tested and improvements can be made). The usability aspect has to be taken into account right from the beginning of the VLE design process.

To ensure usability in virtual learning environments (VLEs):
1. Define the user group(s) of the VLE and the context of use.
2. Make a paper prototype containing few key displays and play the computer while end users are testing the prototype. Make notes of all the actions and comments the users make.
3. Apply the ideas and iterate the tests and the design until no big comments occur.
4. Implement the environment and test it again.
5. When all the critical problems have disappeared, it is time to release the version 1 of the environment.
6. Encourage users to give feedback on the version 1
7. Collect the feedback and use it for improving the design of version 2.
8. Long-term acceptability study (optional).

You will be happy to see a new kind of commitment by the designers, implementers, and students to your VLE. And even more, you can now honestly say that the VLE is especially designed for users; effective, efficient and satisfying to use.

A Recommendation

We recommend that you should visit the usabilitynet site, to see other ISO standards related to usabilty.Figure 1. Project activities and usability actions in Virtu´s development.References

An Alternative Approach in the Use of e-Learning for Digital Inclusion

19 Iunie 2005
Five strategies to overcome mental barriers and empower capacities in a context of computer illiteracy.
This article offers an innovative contribution to the topic of digital inclusion. Most initiatives concerned with digital inclusion tend to focus on hardware issues: donation of computers, cabling homes, use of wireless devices, etc. Considering the specificities of the digitally excluded targets, we will argue, however, that an alternative approach is needed.

Our proposal is based on the main findings of the e-Learning 4 e-Inclusion Project– a European Union project, funded by the eLearning Initiative – that analysed more than 600 activities aimed at promoting digital inclusion.

Digital exclusion is a very vague concept. So-called computer illiterates, leaving aside disabled people, experience very diverse situations such as the ones facing, for instance, the senior citizens, the unemployed, convicts, young people living in difficult circumstances, immigrants and so forth.

For all these groups, designing and implementing ICT teaching schemes isn’t enough. An alternative approach should be developed based on two main imperatives:

  • Overcoming mental barriers (as opposed to simply technological ones)
    We find at present that major causal factors of marginalisation from the information society are those such as the mistrust often felt towards new technologies and the lack of any attractive or useful content for either the socially excluded or those at risk of being so.

  • Focusing on capacity empowerment (as opposed to immediate use)
    What is important is not so much teaching how to use, for instance, Netscape or Outlook, but rather the educational and liberating potential of new technologies. Making the internet an instrument for integrating the socially excluded requires giving them the necessary skills that will make them employable in the information society. This can’t be dissociated from developing their capacity to think critically, to form their own political views and to organise themselves as citizens and cultural groups. ICT should be considered in a broader social dimension rather than through a reductive technical approach.


In this context, we recommend five strategies to efficiently use e-learning for social and digital inclusion.

1. Strategy of combining teaching ICT with other non-digital knowledge equally important to social inclusion. Firstly, the students are much more motivated, since they associate learning ICT with something of genuine concern to them (obtaining a driver’s licence, a job, etc.). Secondly, there is an efficiency factor to combining learning purposes; that is, at the same time learners acquire internet skills, they also acquire others (such as learning how to drive; see the case of the project La casa de Shere Rom focusing on the gypsy community where computers were used as a tool to prepare for a driving exam. Thirdly, the fulfilment of the goal of social inclusion is greatly enhanced, given that not only digital skills are imparted, but also other skills which, though not digital, are nonetheless vital to social inclusion.

2. Communication strategy. Our analysis of failures has demonstrated that if the proposal is not properly communicated, it will not fulfil its objectives. There are innumerable websites dedicated to helping women or immigrants that, however well they may be designed and organised, don’t succeed in doing so because the ‘target group’ doesn’t know they exist. Communication needs to be appropriate to both the target group and its geographical situation – i.e., whether it is local, national or international in character. Furthermore, it must make use of non-digital means to deliver the message, given that the target group is precisely the digitally excluded.

3. Peer to peer teaching strategy. That is, in the degree to which it is possible, it is desirable for the students to teach one to each other. This can be structured either formally or informally. In the former case, the students are ‘promoted’ to the level of teachers; the important implication here is that if enough students are inspired to adopt a teaching role, sustainability is guaranteed. Meanwhile, in less formally structured situations, the help the students may offer will significantly reinforce the cognitive relevance of what is being explained and greatly boost motivation.

4. Creation of an informal environments strategy. This has the advantage of being applicable to various target groups. For instance, the traditional class environment for teaching computer skills can be very boring for children who are not used to them. Organising something more informal and experimental – where the children use the computer as a toy – can be highly effective. Likewise, such formal teaching environments might be intimidating for immigrants whose cultural background is significantly different from the host country’s; they may feel more comfortable in less formal circumstances. Moreover, much the same can be said with regards to certain groups of women and senior citizens.

5. Teaching strategy based on cultural or gender empathy. This approach is particularly well documented in cases of e-learning focused towards women. Since digital technology tends to be thought of as ‘man’s world’, adolescent girls often don’t feel motivated by it. Hence, it can be advantageous to use female monitors to explain the use of a given e-learning environment, as well as female avatars to present content. Though the effect may be a subconscious one, it can be important nonetheless, as it helps to break with the stereotype that only men can handle ICT. A similar phenomenon has been observed in the case of immigrants; an instructor from the same culture tends to be more motivating, however well the immigrant speaks the local language.

Conclusions

The practice of digital inclusion should combine both technical and cognitive approaches. Teaching technical skills involving the use of a computer or internet turn out to be useless if unaccompanied by motivation and contextualisation. The conjunction of these elements is what makes such know-how genuinely useful to the target group and effective in the fight against social exclusion.

New solutions are possible. They have been all too often overlooked, due to the predominance of an exclusively technical focus on the issue. In essence, the strategies put forward move towards a new paradigm, one based upon more informal teaching environments, wherein communication among peers is fundamental and damaging stereotypes regarding new technologies are avoided.

Of course, it goes without saying that these practices are all unfeasible without the necessary minimum of infrastructure, i.e., access to a computer and the internet. However, it is just as clear that investment based on providing technical means is ineffective when unaccompanied by a new methodology, one based on contextualisation and motivation. This text is a summarized version of the article ‘Digital Inclusion: Best practices from e-Learning’, presented at the eLearning for eInclusion Conference.
