Technology-Enhanced Learning...
Technology enhanced learning (or TEL) refers to the support of any learning activity through technology.
TEL is often used synonymously with E Learning even though there are significant differences. The main difference between the two expressions is that TEL focuses on the technological support of any pedagogical approach that utilizes technology. However this is rarely presented as including print technology or the developments around libraries, books and journals in the centuries before computers.
A learning activity can be described in terms of the
- learning resources: creation, distribution, access, compilation, consumption of digital content; tools and services
- actions: communication, collaboration, interaction with software tools
- context: time, duration, surrounding people and location
- roles: A learning activity is carried out by various actors in changing roles(e.g. student, teacher, facilitator, learning coach, human resource or education manager).
- learning objective: to support every human in achieving her or his learning goals, respecting individual as well as organizational person preferences
Approaches to E-Learning Services...
E-learning services have evolved since computers were first used in education. There is a trend to move towards blended learning services, where computer-based activities are integrated with practical or classroom-based situations.
Bates and Poole (2003) and the OECD (2005) suggest that different types or forms of e-learning can be considered as a continuum, from no e-learning, i.e. no use of computers and/or the Internet for teaching and learning, through classroom aids, such as making classroom lecture Powerpoint slides available to students through a course web site or learning management system, to laptop programs, where students are required to bring laptops to class and use them as part of a face-to-face class, to hybrid learning, where classroom time is reduced but not eliminated, with more time devoted to online learning, through to fully online learning, which is a form of distance education. This classification is somewhat similar to that of the Sloan Commission reports on the status of e-learning, which refer to web enhanced, web supplemented and web dependent to reflect increasing intensity of technology use. In the Bates and Poole continuum, 'blended learning' can cover classroom aids, laptops and hybrid learning, while 'distributed learning' can incorporate either hybrid or fully online learning.
It can be seen then that e-learning can describe a wide range of applications, and it is often by no means clear even in peer reviewed research publications which form of e-learning is being discussed. However, Bates and Poole argue that when instructors say they are using e-learning, this most often refers to the use of technology as classroom aids, although over time, there has been a gradual increase in fully online learning.
Computer-based learning...
Computer-based learning, sometimes abbreviated to CBL, refers to the use of computers as a key component of the educational environment. While this can refer to the use of computers in a classroom, the term more broadly refers to a structured environment in which computers are used for teaching purposes. The concept is generally seen as being distinct from the use of computers in ways where learning is at least a peripheral element of the experience (e.g. computer games and web browsing)Computer-Based Training...
Computer-Based Trainings (CBTs) are self-paced learning activities accessible via a computer or handheld device. CBTs typically present content in a linear fashion, much like reading an online book or manual. For this reason they are often used to teach static processes, such as using software or completing mathematical equations. The term Computer-Based Training is often used interchangeably with Web-based training (WBT) with the primary difference being the delivery method. Where CBTs are typically delivered via CD-ROM, WBTs are delivered via the Internet using a web browser. Assessing learning in a CBT usually comes in the form of multiple choice questions, or other assessments that can be easily scored by a computer such as drag-and-drop, radial button, simulation or other interactive means. Assessments are easily scored and recorded via online software, providing immediate end-user feedback and completion status. Users are often able to print completion records in the form of certificates. CBTs provide learning stimulus beyond traditional learning methodology from textbook, manual, or classroom-based instruction. For example, CBTs offer user-friendly solutions for satisfying continuing education requirements. Instead of limiting students to attending courses or reading printing manuals, students are able to acquire knowledge and skills through methods that are much more conducive to individual learning preferences.CBTs can be a good alternative to printed learning materials since rich media, including videos or animations, can easily be embedded to enhance the learning. Another advantage to CBTs are that they can be easily distributed to a wide audience at a relatively low cost once the initial development is completed.
However, CBTs pose some learning challenges as well. Typically the creation of effective CBTs requires enormous resources. The software for developing CBTs (such as Flash or Adobe Director) is often more complex than a subject matter expert or teacher is able to use. In addition, the lack of human interaction can limit both the type of content that can be presented as well as the type of assessment that can be performed. Many learning organizations are beginning to use smaller CBT/WBT activities as part of a broader online learning program which may include online discussion or other interactive elements.
History...
Early E-Learning systems, based on Computer-Based Learning/Training often attempted to replicate autocratic teaching styles whereby the role of the e-learning system was assumed to be for transferring knowledge, as opposed to systems developed later based on Computer Supported Collaborative Learning (CSCL), which encouraged the shared development of knowledge.
As early as 1993, William D. Graziadei described an online computer-delivered lecture, tutorial and assessment project using electronic Mail, two VAX Notes conferences and Gopher/Lynx together with several software programs that allowed students and instructor to create a Virtual Instructional Classroom Environment in Science (VICES) in Research, Education, Service & Teaching (REST). In 1997 Graziadei, W.D., et al., published an article entitled "Building Asynchronous and Synchronous Teaching-Learning Environments: Exploring a Course/Classroom Management System Solution".They described a process at the State University of New York (SUNY) of evaluating products and developing an overall strategy for technology-based course development and management in teaching-learning. The product(s) had to be easy to use and maintain, portable, replicable, scalable, and immediately affordable, and they had to have a high probability of success with long-term cost-effectiveness. Today many technologies can be, and are, used in e-Learning, from blogs to collaborative software, ePortfolios, and virtual classrooms. Most eLearning situations use combinations of these techniques.
Market...
The worldwide e-learning industry is estimated to be worth over thirty-eight (38) billion euros according to conservative estimates, although in the Europian Union only about 20% of e-learning products are produced within the common market.Developments in internet and multimedia technologies are the basic enabler of e-learning, with consulting, content, technologies, services and support being identified as the five key sectors of the e-learning industry.
Higher Education...
By 2006, 3.5 million students were participating in on-line learning at institutions of higher education in the US. According to the Sloan Foundation reports, there has been an increase of around 12-14 per cent per year on average in enrollments for fully online learning over the five years 2004-2009 in the US post-secondary system, compared with an average of approximately 2 per cent increase per year in enrollments overall. Allen and Seamen (2009) claim that almost a quarter of all students in post-secondary education were taking fully online courses in 2008, and a report by Ambient Insight Research suggests that in 2009, 44 per cent of post-secondary students in the USA were taking some or all of their courses online, and projected that this figure would rise to 81 per cent by 2014. Thus it can be seen that e-learning is moving rapidly from the margins to being a predominant form of post-secondary education, at least in the USA.
Many higher education, for-profit institutions, now offer on-line classes. By contrast, only about half of private, n schools offer on-profit them. The Sloan report, based on a poll of academic leaders, says that students generally appear to be at least as satisfied with their on-line classes as they are with traditional ones. Private institutions may become more involved with on-line presentations as the cost of instituting such a system decreases. Properly trained staff must also be hired to work with students on-line. These staff members need to understand the content area, and also be highly trained in the use of the computer and Internet. Online education is rapidly increasing, and online doctoral program have even developed at leading research universities.
Benefits...
E-Learning can provide benefits for the organizations and individuals involved.
1. Improved performance: A 12-year meta-analysis of research by the U.S. Department of Education found that higher education students in online learning generally performed better than those in face-to-face courses.
2. Increased access: Instructors of the highest calibre can share their knowledge across borders, allowing students to attend courses across physical, political, and economic boundaries. Recognized experts have the opportunity of making information available internationally, to anyone interested at minimum costs.
3. Convenience and flexibility to learners: in many contexts, eLearning is self-paced and the learning sessions are available 24x7. Learners are not bound to a specific day/time to physically attend classes. They can also pause learning sessions at their convenience. High technology is not necessary for all online courses. Basic internet access, audio, and video capabilities are common requirements.
4. To develop the skills and competencies needed in the 21st century in particular to ensure that learners have the digital literacy skills required in their discipline, profession or career Bates (2009) states that a major argument for e-learning is that it enables learners to develop essential skills for knowledge-based workers by embedding the use of information and communications technologies within the curriculum. He also argues that using e-learning in this way has major implications for course design and the assessment of learners.
Additional advantages of computer-based training over traditional classroom training include the ability to:
1. Pay less per credit hour
2. Reduce overall training time
3. Spread training out over extended periods of time (even months)
4. Bookmark progress (computer remembering where the student left off so they can resume the courses from there)
5. Remain in one location (e.g., home, office, airport, coffee shop, etc.) with no need to travel (also reduces the cost of transportation to physical classrooms and benefits environment).
6. Participate in class activities when convenient (not tied to class meeting times)
7. Access public content such as webcasts or other course content
8. Access courses from a variety of locations
E Learning...
E learning is defined as instruction delivered on a computer via internet or CD-ROM (Clark & Mayer, 2007). It can be self paced or instructor led and includes media in the form of text, streaming video, and audio and builds user knowledge to improve organizational functioning. E learning commonly refers to training delivered electronically in an organizational setting while Online Learning is used to differentiate courses delivered via the internet in educational settings.
