Recent Developments in Technology-Enhanced Learning: A Critical Assessment

.


Introduction
The last decade has seen numerous new developments in the field of technology-enhanced learning.The one that has attracted by far the greatest deal of public attention is the advent of Massive Open Online Courses (MOOCs), which was triggered by Siemens' (2004) vision of connectivism as a learning theory for the digital age.
The use students make of the digital devices used in technology-enhanced learning environments depends to a large extent on their attitudes towards these devices and on the affordances they perceive in them.
New developments in learning theory with regard to digital devices have also made it necessary to rethink conceptions of instructional designs for the new technology-enhanced learning environments.Posited as a form of integrated research and applied development in education, design research investigates complex pedagogical and technological learning contexts.
The three topics we will discuss in this paper -connectivism and MOOCS, the affordances of digital devices, and design research-are all recent development in the field of technology-enhanced learning.However, they have been developed in different discourses that have paid hardly any attention to each other.In this paper we would like to point out that these topics are interrelated and that all three of them can be integrated into a common theoretical framework.

Learning with digital technologies
In 2004, George Siemens published an article on the Internet entitled "Connectivism: A Learning Theory for the Digital Age".His basic arguments were that classical theories of learning (on behaviorism, cognitivism and constructivism) were developed when today's technologies were not available and that these theories did not address the learning that takes place outside people and within organizations.According to Siemens, "The act of learning… is one of creating an external network of nodes-where we connect and form information and knowledge sources.The learning that happens in our heads is an internal network (neural)" (Siemens, 2006, p. 29).
Siemens' ideas on connectivism also triggered the development of Massive Open Online Courses (MOOCs).In

2008, Siemens and Downes created an open online course on "Connectivism and Connective Knowledge" (CC08).
In total, 2,300 students enrolled on the course, which led Cormier and Alexander to call it a "massive open online course" or MOOC (Siemens, 2012).The MOOCs that Siemens and Downes created (cMOOCs) were based on their ideas on connectivist learning.In cMOOCs, interaction is intended to take place among all members of the course.
On the other hand, in xMOOCs, where x stands for exponential or extended and alludes to the large number of participants, the typical interaction patterns are more likely to resemble those in traditional classrooms, where a teacher provides students with knowledge and the students interact mainly with the teacher.
MOOCs in higher education have received a great deal of attention (Martin, 2012;Armstrong, 2013;Karsenti, 2013;UNESCO, 2013) The role of digital devices in technology-enhanced learning The use of digital devices in learning depends not only on their availability but also on the students' attitudes towards these devices (Kirkwood, & Price, 2005) and the affordances the students perceive in these devices.The notion of affordance, which originated in the work of Gibson (1977), is frequently used to provide a lens or a language to frame an analysis of the capability and learning potential of educational technologies (see, for example Conole, & Dyke, 2004;Bower, 2008;Dalgarno, & Lee, 2010).It is important to differentiate, however, between two competing articulations of the notion of affordance.James J. Gibson's (1977) notion is encapsulated in the following quotations: "the affordance of anything is a specific combination of the properties of its substances and its surfaces taken with reference to an animal" (p.67) and "although an affordance consists of physical properties taken with reference to a certain animal it does not depend on that animal... an affordance is not what is called a subjective quality of a thing... " (p.69).Donald Norman's (1988) definition of the term is similar but, by introducing the idea that the perceived properties as well as the actual ones of an object affect its potential use, the notion is changed in subtle and important ways: "... the term affordance refers to the perceived and actual properties of the thing, primarily those fundamental properties that determine just how the thing could possibly be used... " (p.9).In his later writing (see, for example, Norman, 1999), he emphasizes the importance of the perception of affordance in a more definitive way: "When I get around to revising [The Psychology of Everyday Things], I will make a global change, replacing all instances of the word 'affordance' with the phrase 'perceived affordance' ... the designer cares more about what actions the user perceives to be possible than what is true".When applied in an educational context, Gibson's notion encourages a focus solely on what is possible using the technology irrespective of the prior experience of the educator or students.Norman's notion, on the other hand, which we subscribe to, has the ability to explain decisions taken by educators or students not to adopt an educational technology even in situations where the technology apparently has a clear capability for relevance to the learning situation.
Recent papers on digital devices in education vary in the degree to which they critically analyze the unique affordances of the newer devices and their educational implications.Sharples, Taylor and Vavoula (2010), for example, highlight the consequences of the mobile nature of digital devices for more flexible and social approaches to learning and teaching that go well beyond the traditional classroom context.In a similar vein, Kukulska-Hulme and Traxler (2007) emphasize the ubiquitousness, affordability, and portability of new digital devices and how they open up new possibilities for spontaneous communication and collaboration in the context of teaching and learning activities in both formal and informal settings.Some media commentaries on devices such as the iPad have tended to treat these devices as though they are entirely unique and do not acknowledge the fact that iPad applications, for example, are generally not conceptually different to other interactive learning resources that have been available on other devices for many years.Some commentators have treated apps on mobile devices as though they are something completely new and therefore consider as somehow revolutionary, new technology (when clearly it is not) a drill and practice application on the iPad that is conceptually similar to something we might have seen on the Apple II in the 1980s.In reality, as was demonstrated in a review of 315 iPad applications conducted by Murray and Olcese (2011)

Design research and technology-enhanced learning
The intersection of new emergent learning technologies, learning design and design research requires a reconceptualization of these methods individually as well as collectively (Bannan, Cook, & Pachler, in press).For example, the complexities inherent in educational research in a global context, the natural ambiguity of the creative design process, and the drive for rigor in research methods all present significant challenges.In combination, these challenges multiply but they also provide opportunities for reconsidering and reconceptualizing educational technology or technology-enhanced learning research.Sandoval (2013) recently defined design research as: 1) pursuing the joint goals of improving practice and refining theory; 2) occurring through iterated cycles of design, enactment and analysis; 3) employing methods that link processes of enactment to outcomes; 4) involving sustained engagement with stakeholders; and 5) striving to produce usable knowledge (p.389).Reimann (2013;p. 44) states that design-based research "brings a qualitative change in the relation between design and research" in that the research is "fully integrated as a key component of an ongoing design process and from engaging in long-term collaborations with researchers and practitioners" (p.45).
From the point of view of education-based research, education and learning take place in very complex environments that may be considered learning ecologies (Cobb, Confrey, diSessa, Lehrer, & Schauble, 2003;Gravemeijer, & Cobb, 2006).Education-based research is especially oriented towards research on new themes, new learning tools and new ways of organizing learning environments (Confrey, 2006).Of special interest are learning environments that incorporate digital technologies (Fishman, Marx, Blumenfeld, & Krajcik, 2004;de Jong, & Pieters, 2006;Lajoie, & Azevedo, 2006).
Design research has gained attention over the last ten years in multiple publications and academic practices (McKenney, & Reeves, 2012;Anderson, & Shattuck, 2012;Kelly, Lesh, & Baek, 2008).Posited as a form of integrated research and applied development in education, design research has been leveraged to investigate complex pedagogical and technological learning contexts.One aim of design research is to identify and model technologymediated, social learning and behaviors in order to design tools that support and promote the practices under investigation.Researchers have embraced this type of research as a form of inquiry that will best position them to generate learning theory and to generate and test solutions for complex problems in contexts for which no clear guidelines or solutions are available (McKenney, & Reeves, 2012).
Accordingly, conducting educational design research on a global level presents unforeseen challenges for design research, design process and learning research.For example, Traxler (2013) presents evidence to suggest mobile technology now dictates the agenda for prior educational technologies by providing learning opportunities to disenfranchised populations across the world who were "previously too distant or expensive to reach" and that their inclusion is "enhancing, enriching and challenging the conceptions of learning itself " (p.237).

Discussion
Siemens' ideas on connectivism are certainly some of the most interesting proposals on technology-enhanced learning presented in the last decade.Although Siemens suggests that connectivism is a learning theory for the digital age, it may be queried whether connectivism actually is one (Kop, & Hill, 2008).According to Verhagen (2006), it is more of a pedagogical view than a learning theory.In their critical analysis of Siemens' approach, Duke, Harper and Johnston (2013) reached the conclusion that connectivism as described by Siemens is "a tool to be used in the learning process for instruction or curriculum rather than a standalone learning theory" (Duke, Harper, & Johnston, 2013, p. 10).Nevertheless, the idea that people who are interested in a specific problem or field of knowledge connect with each other online to study available knowledge, gain new insights, and possibly create new knowledge is certainly an intriguing vision and is one that is particularly apt for describing learning that takes place in the kind of MOOCs that Siemens was thinking about (connectivist or cMOOCs).
Most MOOCs however, are just that -Massive Open Online Courses, i.e. online courses with a very large number of registered students.Despite public enthusiasm for MOOCs, MOOC participants seem to have serious problems and dropout rates are huge.A recent study showed that only 4% of students attending Coursera MOOCs completed their courses (Armstrong, 2013).The very low retention rate of MOOC participants has also been of concern to other researchers (Koller, Ng, Do, & Chen, 2013;Yang, Sinha, Adamson, & Rose, 2013).One problem may be that many courses were created without taking into account the findings from research in the fields of learning and self-regulated learning (Bartolomé, & Steffens, 2015).
It seems, however, that the original excitement about MOOCs is gradually fading (Zemsky, 2014;Kolowich, 2015).Nevertheless, we expect that MOOCs are here to stay.Most likely, they will be offered in parallel to regular university courses (without replacing them) and might be made components of programs leading to nanodegrees, i.e. degrees of a lower level than traditional bachelor or master degrees (Zapata-Ros, 2014).While Karsenti (2013) believes that MOOCs will have a transformative impact on universities, he also states that "It would also be important to keep uppermost in our minds that neither technologies in general nor MOOCs in particular will foster successful university careers.Instead, it is the use that the students will make of them" (Karsenti, 2013, p. 34).
The use that students will make of MOOCs and of digital devices in general will very much depend on their attitudes towards these devices and on the affordances they perceive in them.In articulating a position on the implications of technology-enhanced learning environments for student learning, it is essential to be clear on the broader role of technology in the learning process.Numerous authors, most notably Selwyn (2010Selwyn ( , 2012) ) have criticized educational technology research that adopts a technocentric or a technodeterminist stance.
Technodeterminism assumes that integrating technology into the learning process is by its very nature positive or desirable, while technocentrism focuses too much on the objective capabilities of the technology and too little on the social and contextual aspects of the learning situation.In this paper we totally reject any notion of technodeterminism and have attempted to ensure a more critical approach.Nor do we accept the notion of technocentrism since we focus on encapsulating the broader social and contextual issues.
Underpinning our position on the relationship between technology and learning is the notion of affordances.
Specifically, we see technology as affording particular learning tasks for particular learners in a particular context, and we see these learning tasks as then contributing to student learning.We are making two important points here.
First, we reject any direct causal relationship between the use of particular technologies and particular learning outcomes.We see the learning outcomes as occurring through the learning activities and, although a particular technology can afford a particular learning activity, the provision of a specific technology never guarantees that the learning activity will occur for all learners and it is never the only way to afford a particular activity.Second, we see the learning affordances of a particular technology as being dependent on the prior experiences of the learner.
As a result, they are different for different learners.
Given the definition of design research as a catalyst in the changing landscape of educational research, it behoves educational researchers to re-examine research methods and contexts that particularly relate to the current affordances of emerging digital technologies for education.
Designing learning and conducting design research in learning with new forms of ubiquitous, seamless and sensor-based technologies adds another layer of complexity to the research process.For example, the technological affordances and pedagogical considerations of mobile learning technologies blur the lines between formal and informal education regarding who facilitates learning, what learning is facilitated, and where learning is facilitated (e.g. is it user-generated and socially shared and are the technologies location-aware?).They also promote the powerful potential of leveraging simultaneous, in-situ, real-world and virtual data (e.g.augmented reality applications provide digital layering of real world information in real time) and illustrate exactly how these new technological "mixed reality" capabilities may impact applicable design processes and educational research methods for design research (Bannan, Cook, & Pachler, in press).

Conclusions
The three topics that we have discussed in this paper -connectivism and MOOCs, digital devices and their affordances, and design research-have only recently entered the discussion on technology-enhanced learning.They constitute three different strands developed in three different discourses that seem to have been hardly aware of each other.
Interestingly, it is the first of these topics that has received by far the greatest amount of public attention in the last few years.The New York Times even named 2012 "The year of the MOOC" (Pappano, 2012).From an educational point of view, this is quite surprising.It is difficult to see why online courses that are open to masses of students should have any advantage over traditional online courses in helping students learn.We would not expect students to learn better from hard cover books than from paperback editions, although students might prefer paperback editions because they are cheaper and weigh less.It is also true that we are still lacking empirical evidence on the impact of MOOCs on student learning.Nonetheless, we believe that MOOCs are here to stay and deserve a critical examination.Also, Siemens' ideas on connectivism, which gave rise to the development of cMOOCs, have opened up a new perspective on technology-enhanced learning (Yeager, Hurley-Dasgupta, & Bliss, 2013).
As Li (2014) pointed out, in thinking about technology-enhanced learning we will have to take into account the relationships between the learner, the learning context and the technology.Referring to Archer's morphogenetic approach (Archer, 1995), she suggests that the development of an online course (she even refers to a MOOC in her example) may include several morphogenetic cycles, beginning with the structural conditions of the learning context including the external context (political, social, and cultural), a delivery platform, and instructional design (designed learning outcomes, learning materials, and teaching and learning activities).Students with different characteristics (motivation, prior knowledge, and digital literacy) enter this learning context, interpret it from their point of view, and interact with its technology as well as with their peers and tutors.Their interaction may result in changes in the learning context which then give rise to another morphogenetic cycle (Li, 2014, p. 16).Li's (2014) background is realist social theory and in her contribution she focuses on the social interaction that takes place in a learning environment and the extent to which this is influenced by its structure.There are some interesting parallels between her line of reasoning and ours.We also believe that the affordances of digital devices influence students' learning.However, we believe that it is the perceived affordances that matter while Li argues that affordances are a more objective aspect of the structural conditions of the learning context.There is another interesting parallel between Li's presentation of the morphogenetic approach and our presentation of design research.As stated by Sandoval (2013), one of the important aspects of design research is that it occurs through iterated cycles of design, enactment and analysis.
Although the three topics we have discussed in our paper -connectivism and MOOCs, digital devices and their affordances, and design research-are different strands that were developed in three different discourses that seem to have hardly been aware of each other, we believe that they are related in both practice and theory.We believe that design theory has the capacity to integrate these three topics by describing the learner as an agent in , very few applications really capitalize on the device's unique educational affordances to allow educators to design learning activities beyond what would be capable without the device.RUSC Vol. 12 No. 2 Special Issue | Universitat Oberta de Catalunya and University of New England | Barcelona, April 2015 CC K.

MOOCs may be considered special forms of online courses, which have a long tradition in distance education.Their innovative aspect lies in the fact that they are online courses in which huge numbers of students participate.RUSC Vol. 12 No. 2 Special Issue | Universitat Oberta de Catalunya and University of New England | Barcelona, April 2015 CC K.
