Introduction

This literature review began as an investigation on mobile learning but really ended up reviewing a far wider range of issues such as the digital divide and barriers such as prevailing attitudes and fears. It has led me to consider mobile technologies not so much as something separate from e-learning but as a natural progression in our networking and communication capabilities, taking learning outside the classroom and outside school hours. Are the advancements in the small portable devices going to provide the possibility of one-to-one computing (one computing device for each student)? Could this give us a chance to realize the vision to foster technological and new media literacies (Chan et al., 2006)? How can we harness the enthusiasm and popularity of these mobile devices amongst this generation of students to add value to education and enhance the learning/teaching process? 

The purpose of this essay is to investigate the opportunities provided to education by mobile technologies in a balanced unbiased way so the advantages and disadvantages are equally considered.

1. A learner centred approach

1.1.  The Student Needs

Most of our present generation of students were brought up as Digital Natives (Prensky) using computers and mobile phones. The immediacy of Short Message Service (SMS) instant messages has become the norm. We may hear the older Digital Immigrants complaining about the limited size of screens and buttons on MWDs but "it is precisely the combination of miniaturization, mobility, and power that grabs today's Digital Natives." (Prensky, 2005) Mobile phones are now owned by 95% of Australians (Low, 2007) opening the possibilities for mobile communication in education (Viteli, 2000).

Dede (2005) considers the needs of today's students in terms of their "Neomillennial Learning Styles". Students are now fluent in multiple media, they prefer to collectively "seek, sieve, and synthesise" experiences rather than individually locate and absorb information from a single best source. They want active learning experiences based on real or simulated experience with opportunities for reflection. Their preferred medium for expression is nonlinear, associational webs of representation rather than linear "stories" and they want to be co-designers of their learning experience so they can personalise it according to their individual needs and preferences (Dede, 2005).

Sword & Leggott, (2007) believe that that if the Ne[x]t Generation of students are to face the intellectual, technological, and cultural challenges of the future without losing sight of the past we will need to adopt teaching methods that will cultivate their ability to see both forwards and backwards. They suggest the following seven key strategies to do this:
1. relinquish authority,
2. recast students as teachers, researchers, and producers of knowledge,
3. promote collaborative relationships,
4. cultivate Multiple Intelligences,
5. foster critical creativity,
6. encourage resilience in the face of change and
7. craft assignments that look both forward and backwards.

These Digital Natives, the Ne[x]t Generation with Neomillennial Learning Styles, do not want to memorise endless facts because today's facts are often tomorrow's history. They want and need skills for the future.

"The tolerance of consumers for a traditional pedagogical approach is fast disappearing." (Peters, 2005)

1.2. New Pedagogies

New pedagogies already exist that can accommodate these neomillennial learning styles to meet the evolving needs and interests of our students (Dede, 2006). These new pedagogies are underpinned by a social constructivist learning theory (Vygotsky, 1978), principles of situated learning (Lave and Wenger, 1991), ideas of distributed cognition and connectivism (Siemens 2004) emphasising the connectedness of learners (Low & O'Connell 2006). This learner centered educational philosophy is based on giving the learner a degree of control over their own learning to "provide challenge, motivation and engagement for a wide range of student groups." (Hennessy et al, 2007. p.140) 

Solving real-world problems motivates these students. They want Authentic Learning and they prefer doing rather than listening. Immersion in authentic learning experiences cultivates "portable skills", transferable knowledge, such as critical thinking, judgment, patience, discrimination and flexibility. The benefits of authentic activity "can be realized through careful design of Web-based learning environments."(Herrington et al., 2002, Cited in  Lombardi & Oblinger, 2007). We will later explore how mobile learning experiences can provide these authentic activities.

Teacher and student roles have to change when these new pedagogies are adopted. The teacher becomes the facilitator rather than the leader and source of knowledge. The student becomes a co-desiger with power to influence the learning experience and a co-instructor as they engage in collaboration and peer tutoring (Dede 2005).

These new pedagogies emphasise the social means of learning so students are often working in collaborative groups, they become a community of learners whose focus is on "knowledge building" (Scardamalia & Bereiter, 2003) rather than on knowledge acquisition. They are actively constructing dynamic knowledge and understanding, no longer absorbing information as passive receptacles that will regurgitate static facts.

Kukulska-Hulme and Traxler (2005) make a distinction between didactic and discursive learning with mobile technology. A didactic approach would be to deliver learning materials to the device for the student to absorb. A discursive approach implies that the student uses the device for interactions and discourse with others in the learning community (p.26).

"The skills of constructing and exploring knowledge, conversing and collaborating with peers, and the ability to control one's own learning are fundamental requirements of effective learning" 
(Sharples 2001:7, cited in Kukulska-Hulme and Traxler 2005, p.30)

 

2.  Technological Opportunities

2.1.   Affordances of MWDs

The primary concern must always be on how the technology can enhance learning outcomes within the framework of these new pedagogies. MWDs provide "new opportunities…to be more intensely connected" (Roschelle, J. et al. 2005, p. 159).

"By utilizing computing power and wireless capability, these mobile technologies can make learning expedient, immediate, authentic, accessible, efficient and convenient" (Curtis et al. 2002; Kynäslahti 2003; Ogata &Yano 2004, cited in Lai et al, 2007, p.3)

Mobile technologies provide learning that is:

  •  Social, multi-way communications for social interaction;
  •  Situated (typically in the field or at the workplace);
  •  Contextualised through mediation with peers and teachers;
  •  Instant (with guidance and feedback);
  •  Accessable and available on demand (learning materials);
  •  Portable, flexible, anywhere and anytime (way to overcome barriers for those separated by huge distances);
  •  Interactivity, facilitating student control of the learning process;
  •  Personalised, tailored to the individual learner;
  •  Rapid, just-in-time learning.

All of these provisions support social, active, productive, creative, and collaborative learning that can increase student motivation, participation and engagement. It provides opportunities for any time, any place access to web-based information that can be used to expand the learning experience (Peters, 2005) and thus create Portable Personal Learning Environments (PPLEs). One-to-one computing with wireless connectivity can enable PPLEs but ownership of the device is important if the student is going to use it. These PPLEs serve as "gateways to rich, highly contextualised activities, virtual environments and augmented realities.

MWDs are also able to create a Seamless Learning Space which extends "formal learning time, usually limited to the classroom, into informal learning time, to embrace opportunities for out-of-school learning driven by the personal interests of students" (Computer Research Associations, 2005).

Note that, MWDs are 'personal' so if the device is loaned it is portable but not personal hence the "loaned device may not be appropriated by its user or integrated into daily patterns of activity" (Kakulska-Hulme, 2005, p.192).

2.3. Accessibility

In order to utilize the mobile technologies, outlined in the previous section, it will be essential to create learning materials in formats that are compatible and easily accessible with all of these various devices (Corbeil & Valdes-Corbeil, 2007). This highlights the "need for standards-based, portable content that can be reused in multiple environments and for different pedagogical purposes" and for "publishers to focus on 'granular' and highly 'portable' content that can be used and repurposed easily" (Reynolds, 2005:para.4, cited in Ragus 2006). Rae's glossary (in Kukulska-Hulme & Traxler, 2005) defines this characteristic as 'bite-size' gobbets of information designed to be short enough to be readable on a Pocket PC or mobile phone, for example about 800 words plus a couple of pictures (p.197). Reynolds suggests that this can achieved easily by building and providing teaching templates or "how-to" models that can be reused on multiple platforms. This means the design needs to be standardised according to the Shareable Content Object Reference Model (SCORM) to make them portable across platforms and devices. (Kukulska-Hulme & Traxler, 2005, p.34)

 

3.  Developing a Teaching Methodology 

3.1.   New Learning Styles

The next question is how can we use these MWDs to enhance teaching and learning? Can mobile technologies be used to promote deep knowledge and transferable skills?  We can begin to answer these questions by considering how to use the devices can be used to "facilitate listening, observing, imitating, questioning, reflecting, estimating, predicting, hypothesising and practicing functions" (Edwards, R. 2005, p.52). Alternatively, these questions can be considered from simpler learning activities suggested by Prensky and Brown, the "Four R's" for Net Generation learning:

  • Record: The learner as a gatherer and "builder" of new knowledge.
  • Reinterpret: The learner as an analyst of existing data to discover new knowledge.
  • Recall: The learner as a user of existing information and resources.
  • Relate: The learner as part of a social context and a network of knowledge.

(Prensky 2001a, 2001b; Brown, 2002, cited in Low & O'Connell, 2006).

M-learning does offer the opportunity for a contextualised authentic learning experience but it still needs skilled facilitation and guidance from teachers if learners are to benefit. Skilled facilitation and guidance can help to deepen their understanding of these situated activities (Low & O'Connell 2006).

 

3.2 Good m-learning makes the most of the affordances provided by the technology within a structure that provides: 

  • guidance (supervisor, co-worker and assessor),
  • discussion (via the moblog and email),
  • critical thinking (trainee revises ideas following input of others or review of procedure herself),
  • ownership and reward for effort (the trainee's recording, subsequently rewarded for effort via workplace acknowledgement and achieving competency). (Low & O'Connell 2006).

 

3.3  Uses for m-learning

Much like many other new technologies, how they are used is really only limited by ones imagination and proficiency with the tools. Below is a list of just some ideas for use in education:

  • Administration:
    • Automated mobile data recording such as making the roll on a PDA and sending it directly to the administration office.
    • Text message automatically sent to parents who's children are absent (reduce truancy)
    • Course or class administration- student records on PDAs
  • Organisation:
    • Daily news sent directly to teachers and students with a PDA or mobile phone.
    • Room changes or messages instantly sent by SMS to teachers and students
    • mobile technologies such as Barcodes for libraries
  • Teaching aids:
    • Flexible learning provided for distance education students by recording and transmitting lessons via Pod casts.
    • Field-trip-based and outdoor learning extending scope of current education
  • Learning support tools:
    • Scientific data collection
    • Visual journalism- Creative cell phone photos can inspire students' creative writing via caption or story contests.
    • Virtual library of electronic documentation in our pockets at an affordable rate.

 

4.  Issues Facing the Implementation of these Technologies.

4.1. The Digital Divide

The Digital Divide refers to the chasm between the "haves" and the "have-nots" of digital devices. Overcoming this issue of device ownership, having one-to-one computing, is an essential hurdle that must be crossed if we are to cross this chasm that causes this digital divide. Narrowing this digital divide is possible if the cost of the digital devices drops enough for every single student to have one (Chan et al., 2006). The relative low cost of mobile phones may provide the means to cross this digital divide.

 

4.2. Attitudes and Fear 

 Educational conversations about mobiles in schools are still dominated by questions of control & regulation (Goggin, 2005). It is public knowledge that the SMS casting service available on mobile phones was used to gather people to the 2005 Cronulla riots. This type of incident causes "moral panics" which are often associated with the regulation of sub-cultural groups by dominant groups (Goggin 2005). People are afraid of these negative possibilities. The existing conservative 'social and hierarchical ' structures in educational institutions makes them slow to change and adverse to these types of risk.  The use of SMS casting service is still bogged down in issues such as the cost of the calls and who pays.

 

4.3. The Up side

4.3.1. For the Student

A mobile learner is able to:

  • upload information to web-based tools,
  • interact with the tools using mobile internet,
  • integrate web 2.0 services and
  • share mobile learning resources

These abilities can be used to construct a 'mobile, social ecology' surrounding a mobile learner (Low, 2006).

4.3.2. For the Teacher

M-learning does have the potential to free up teachers from the delivery of materials to focus on the management of learning ways that will prepare students for their future in the information age. However, the adoption of this innovation would probably redefine the role of teachers. Traxer (2005) describes an interesting possible outcome. It could mean less face-to-face contact with students and the development of content and learning objects may be done by what he calls "'para-academics' (staff skilled in learning materials, design, graphics, technologies and content) (Kukulska-Hulme & Traxler 2005, p.30).

4.3.3.  For the Community

Howard (2005, cited in Chan et al.) predicts that cell phones and wireless devices will "allow global participation on a scale not yet seen. New online communities will emerge and social networking will expand. Free access to information and a means for anyone to participate will be available to huge numbers of people previously excluded from the information age. This will have a significant impact in politics, government, business, religion and education on our institutions". (p.18) 

 

4.4.   The Potential Downside

Blending informal and formal environments with pervasive computing as a threat to a balanced life.

  • Challenging data security, integrity, and privacy issues.
  • Being co-opted into the industry logic of a persistent digital divide.
  • The high environmental and ecological costs of low-cost pervasive computing.
    Chan et al., (2006)

These issues certainly warrant further discussion but I must refer you to the article by Chan et al. (2006) for this.

 

5.  Conclusion

Useability issues limit the use of MWDs to certain tasks that are "content light". Chan et al. (2006) argue that three factors "will create the potential for a new phase in the evolution of technology-enhanced learning, characterized by 'seamless learning spaces'." (Chan et al., 2006, p.)

  1. Ubiquitous access to mobile, connected, and personal, handhelds.

  2. The relentless pace of technological developments in one-to-one computing.

  3. The evolution of new innovative uses of these handhelds.
     

Ragus (2006) agrees that mobile learning has an enormous potential for the teacher's 'kit of creative practice' but he warns that we will need a planned and structured system that incorporates this technology into the day to day operations of learning organisations, from administration to learning delivery and from staff to the learners" if we are going to realise the potential. So many educational innovations have failed to add value to education, not because they lack potential, but "because of poor adoption, implementation, institutionalization, and support strategies" (Tinker et al, 2007).
