Blended Learning: A way to assist learners in rural sectors
The term “Blended learning” is used frequently along with the term “e-Learning”. Is it just another buzz word or an old wine in a new bottle?
It is
relevant to review the present situation in the country with reference to
computer literacy and the percentage of households owning computers in
different sectors, urban, rural, estate, etc. Computer literacy/Computer
ownership as a percentage (Sri Lanka: 30.1/22.2, Urban: 41.5/38.3, Rural: 28.6/19.9,
Estate: 13.7/3.8), as per the published statistics.
The
above statistics clearly indicate a vast disparity within the sectors in
computer literacy and ownership of computers by households. Under such
situation, a heavy emphasis on e-learning or technology based education could worsen
the present relative social standing of rural and estate sectors. While actions
need to be taken to reduce the above disparities in the longer run, it is
imperative that less privileged sectors be provided with facilities such as
blended learning to mitigate the disparities currently exist.
Blended learning is defined as a combination of multiple approaches to
pedagogy or teaching. It is achieved through the combination of virtual and
physical resources. Blended learning is a blend between
e-Learning and traditional delivery methods such as traditional class rooms,
printed learning material, etc.
Most learners are familiar with how teachers use
different delivery methods to achieve learning outcomes, e.g. lectures,
discussion groups, drills and practices, role plays, audio/video clips,
computer-based tutorials, etc. Therefore, it can be said that blended learning is a new name for an
old concept.
Blended learning can cater to a large cross section of
learners including rural and estate sectors in achieving their learning goals
by accommodating different modes of delivery, models of teaching and styles of
learning. All students do not learn in just the same way nor do they have same
accessibility to technology; therefore, it is important to provide different
methods, media and approaches to learn the same content by different students.
With regular Internet, TV, radio, etc., it is possible
to deliver educational and training content for the benefit of the learners
throughout the country. The content could include material for school and
university programmes, improvement of general skills such as English knowledge
and computer literacy, vocational skills such as repair and maintenance of
automobiles, computers, etc. However, those who are familiar with distance
learning are aware of the main hardships the learners face; the lack of tutor support and feedback.
The "theory" part of the learning task
can be delivered through the technology mentioned above. How can the tutor support and feedback be provided? The way to proceed may be to use a blended
learning approach. It is possible to meet the above learner needs through a
combination of online and face-to-face tutor support. Face-to-face tutor
support can be provided at venues such as Open University's regional centres, University
of Vocational Technology, technical colleges, and other suitable public and
private sector educational establishments. This is a feasible approach that would
directly benefit the rural sector learners.
The learners would choose the method that suits them
best based on preference, accessibility, affordability, etc. Different
approaches in delivery are also necessary due to different learning contexts
(traditional learning, distance learning, etc.), learner types (auditory
learners, visual learners, etc.) and leaning tasks (facts, concepts, etc.).
Also, when the technology is not equally accessible to the entire cross-section
of learners, blended learning could
provide alternatives to choose from.
The factors that influence the blend of methods and
technologies used to achieve desired learning objectives include: learning
context, type of learners, learning task, availability, accessibility and
learner attitudes towards using technology for learning, time availability for
learning, language and subject proficiency levels, pace at which learning goals
are to be achieved, the pedagogical approaches.
The actual making of the ‘blend’ should be based on
proper study and evaluation of the learning situation. Such study is
called Instructional Design. A typical instructional design process
includes five stages; Analysis, Design, Development, Implementation,
and Evaluation (ADDIE). The most critical of these stages is the
first stage, Analysis. Analysis is the basis for design of instructions and
their delivery. The Analysis stage consists of three components; analysis of
learning context, the learner, and the learning task. The selection of the type
of instruction and the mode of its delivery is based on the findings of the
instructional analysis. Analyses of the learning context and the types of
learners will provide information on: gaps in knowledge, learner background, preferred
styles of learning, performance levels, language proficiency, computer
literacy, access and attitude towards technology, time constraints, etc.
These findings have implications on the design and
delivery of instructions. For example, if most of the learners are either
auditory or visual learners, the design of instruction should include audio and
video components. Similarly, if the learners are adults who work full-time or
part-time, face-to-face delivery of instruction is not suitable as the primary
mode of delivery. In this case the design and delivery of instruction should be
made to suit a distance learning environment. Then, the question arises as to
what type of distance learning is affordable. Does the learner have access to
ICT where instructions can be delivered in the form of offline content or
online through the Internet? If the learners have no access to ICT, then the
option will be to provide the learners with print material designed for
distance learning or media broadcasts. If the analysis shows that a good part
of the learners have access to ICT, then the delivery of learning content should
be made through both ICT, print material and/or media broadcasts. This is just
an example of blending different methods of delivery of instruction to suit
different types of learners and learning contexts.
Blended learning methods also become relevant when
implementation of different steps in the learning process is considered. The
different steps that a learner needs to go through to accomplish a learning
task are known as Events of Instruction. There are nine events of instruction: Gaining
attention, informing the learner of the objective, stimulating learner’s
attention, stimulating recall of prior knowledge, providing learning guidance,
eliciting performance, providing feedback, assessing performance, and enhancing
retention and transfer. Different approaches or media could be used to achieve
each event of instruction.
The type of learning task too has a bearing on the
methods of delivery. Design of events of instruction varies from task to task.
Providing learning guidance, eliciting performance, giving feedback, etc. will
be dependent on the type of learning task and mode of delivery. Giving feedback
on learner performance will be quite different in a computer-based learning
environment as compared to a face-to-face learning environment. Also, intelligent
tutoring systems can evaluate the learner input and suggest possible
routes for solving a problem or task. It is the instructional designer’s task
therefore to select the appropriate mix of media to ensure effective learning
under a given learning situation.
However, the challenges associated with such an
endeavour include the design and development of suitable indigenous learning
content suitable for delivery through technology and design and implementation
of pedagogically sound blended learning environments that will result in
successful learning outcomes.
With
such blended learning settings, a large portion of the country's population including
those in rural sectors can benefit from the new technology and the country can
steadily move towards its vision to become a knowledge-based economy with a
more equitable society.
