The Enormous Technological Challenges Facing Education
Advances in technology continue to change how adults view and interact with the world. Of course, those same advances are available to teachers and the youngsters who populate their classrooms.
These developments are leading to enormous challenges for teachers regarding the role digital devices can and should play in the learning process. For some educators, the view is that technology should only be utilized as a tool to help facilitate student understanding and mastery of the current curriculum. For other educators, technology is as fundamental to learning as reading and writing and therefore must become a separate segment of the school curriculum.
To get a sense of the differences in these viewpoints, we turn to the 2011 Horizon Report (pdf), the eighth in the ongoing annual series of reports from Educause focused on emerging technology in higher education. As in the past, the current Horizon Report seeks to highlight the six emerging technologies or practices that are likely to enter mainstream use within three adoption horizons: near-term (those technologies that will see adoption over the next twelve months), mid-term (those that will be adopted over a 12-36 month period), and far-term (those that will be pursued over the 36-60 month time frame).
The 2011 report identified the following specific areas as technologies to watch:
– Near-term: mobile computing and open content.
– Mid-term: electronic books and simple augmented reality.
– Far-term: gesture-based computing and visual data analysis.
Most educators are no doubt very familiar with the first three elements noted in the Horizon report. These topics have garnered a lot of press over the last couple of years and their use is becoming more common in Pre K-12 classrooms.
The last three, on the other hand, are not generally seeing much if any time in the current learning environment. But if tomorrow’s workers are going to be ready to take advantage of the incredible technological progress available to them, teachers will need to become more knowledgeable of these incredible new options.
In that regard, one of the critical findings of the report centers on the issue of digital media literacy and the subsequent challenges that literacy creates for educators. The report reveals the significance of digital media literacy in every discipline and profession but that formal training in digital literacy skills and techniques is rarely found in teacher education programs. Worse yet, the Horizon report reveals that formal training is virtually non-existent in higher education.
While many educators are working on the topic in an informal manner, the fact remains that literacy is deemed to be “less about tools and more about thinking.” Therefore, a systems approach to digital literacy is necessary if we are to ensure that teachers are ready and able to lead students down this ever-evolving path.
Below we examine the six areas briefly and the challenges facing educators in implementing these short-term, mid-term, and far-term technologies. For greater depth, readers may simply turn to the Horizon’s 2011 detailed report (pdf – 40 pages).
1. Mobile Technology
Today, we have a wealth of options for staying connected while on the go. While many equate the idea of mobile technology with the cell phone, the term mobile device is used to categorize everything from smart phones to netbooks.
Today, not only are there many devices (smart phones, netbooks, laptops and the like) to choose from, each of these options is capable of performing multiple functions. Whatever the choice, the ability to access the Internet and personal data from anywhere in the world is becoming ever more important especially as technology becomes cloud-based.
Ultimately, this online data storage is creating a totally new view of IT support. It also creates the requirement that our information be accessible to us no matter what our choice of device or our location.
The result is that more and more people are looking to mobiles as their device of choice. Furthermore, they are generally seen as cheaper and easier to use than desktop or laptop computers.
While many have long espoused the potential of mobile devices to revolutionize learning, educators continue to have concerns with the privacy and classroom management issues that come with student use of such devices. But clearly the digital world is headed firmly in this direction and education must follow suit.
2. Open Content
Open content appears to carry fewer concerns for educators and is generally seen as critical to addressing the ever-rising costs of higher education. Perhaps even more importantly, open content has the ability to provide the level of flexibility today’s students are beginning to demand.
Providing individual choice as to when and how to learn, open content is already becoming a critical format for colleges and universities. As traditional lines of learning get further blurred by the needs of adults to constantly upgrade skills to remain competitive in the workplace, education must follow suit.
The ability to learn informally, without constant direction and supervision, is a skill that we must increasingly begin to utilize in the classrooms of tomorrow. And whereas education used to center on a just-in-case format (becoming knowledgeable in a wide variety of topics to ensure future flexibility) the easy access to information requires a switch to “just-in-time” and “found” learning. Both of these formats will ensure that learning is far more timely and efficient.
This demands a new educational perspective where knowledge is not held by a select few and shared only upon demand but instead is collective in nature and sharable. This will continue to push teachers towards a new model where they focus on guiding and coaching students on methods for accessing and evaluating the volume of information available.
3. Electronic Books
While the Horizon report notes that “electronic books have been available in some form for nearly four decades,” the last twelve months “have seen a dramatic upswing in their acceptance and use.” Add to the mix the various assortment of electronic reading devices now available and it is easy to see why “electronic books are appearing on campuses with increasing frequency.”
For the student with the overweight backpack, the idea of being able to carry an entire library in their book bag is enormously appealing. On the college campus, electronic books are not only proving to be a cost-effective and portable alternative to heavy textbooks, these devices are able to store all syllabi and supplemental reading selections for even the most intense courses.
The latest e-book readers not only rival the experience of reading a paper book, they offer the ability to easily mark up and highlight text when desired, annotations that can be easily exported and shared with fellow students. Perhaps even more importantly, electronic readers offer keyword searching and instant dictionary lookups, two elements that can greatly enhance the learning possibilities for students.
Today we see the list of available titles is growing rapidly and with that development, the new format’s convenience will also yield even greater cost-effectiveness over time. Throw the fact that our wireless devices enable individuals to purchase materials from nearly anywhere on the planet means that entire libraries are now available to both teachers and students without ever leaving their home or the walls of their respective classroom.
4. Simple Augmented Reality
The ability to combine the real world with virtual information is the fundamental tenet of what is referred to as augmented reality. It involves the blending of virtual data, the information available to users via technology, with live action and what we see in the real world.
According to the Horizon report, AR dates back to the late 1960s and 1970 though it was not until the 1990s that major companies put the technology to use for visualization and training purposes. Those applications once required headsets that kept users tethered to their desktop computers but now the camera and screen embedded in smart phones and other mobile devices (our basic GPS system) can serve as the tools to blend the real world with virtual data.
Augmented reality applications exist in two basic formats: marker-based, whereby a “camera must perceive a specific visual cue in order for the software to call up the correct information,’ and markerless, whereby “positional data, such as a mobile’s GPS and compass is compared against a library of images to find a match.”
For education, the major focus could well be on augmented reality gaming. Such games would be based on real world situations that are then augmented with networked data, bringing incredible life to the study of both history and geography.
For the extremely futuristic minded, there is also the development of augmented reality books. Though the books are printed normally, they are made so as to include AR elements. After purchase, special software installed on a webcam allows the camera to interact with the book to create three dimensional visualizations.
5. Gesture Based Computing
Gesture-based computing gives rise to truly transformative technology where devices are created “that react to us instead of requiring us to learn to work with them.” Therefore, instead of teaching children how to use a mouse and keyboard, we would instead teach them to use natural movements to engage their technology.
Most of us are familiar with the iPhone or the Nintendo Wii, gesture-based systems that accept input in the form of taps, swipes, motion, pressure, and the number of fingers touching the devices. Incorporating the potential for more kinesthetic classroom would also take away one of the current fears associated with computers and those popular video games, the sedentary lifestyle that often accompanies those activities.
In addition, yet another one of the most important elements would be the collaborative nature gesture-based computing would offer teachers. By removing the need to share a keyboard and mouse, gestural interfaces would allow multiple users to potentially interact with a single computer simultaneously.
More than simply making technology easier to engage, gesture-based computing has been shown to enhance fine motor skills. One such study revealed that surgeons-in-training who warmed up with the Wii scored an average of 48% higher on tool tests and simulated surgical procedures than those who did not.
6. Visual Data Analysis
Visual data analysis is a new field that blends highly advanced computational methods with sophisticated graphic generating tools. These computer enhancements make it possible for almost anyone to see any existing patterns and/or structure in even the most complex of data settings.
Data collection and compilation has long been seen as a tedious process. While computers removed some of the manual challenges of this process, analyzing, interpreting, and displaying data was largely a field only statisticians and engineers fully grasped.
Most people see these tools as being useful when studying scientific topics such as climate change and global warming trends. But if we can make “it possible for anyone to sift through, display, and understand complex concepts and relationships,” then visual data representation will soon lead to applications in the social sciences and humanities.
As for the implications for educators, the field is deemed to be more consistent with the pattern matching skills that seem to be hard-wired into the human brain. But the greatest impact could well be the concept’s ability to enable educational researchers to finally isolate the specific variables that truly impact learning and identify the most effective educational practices to employ in the classroom.
