Mediation-Based Pedagogy
The principal means of disseminating the content in the DSH
database is shipping DVDs to spoke schools. Each spoke school is given
at least a TV and a DVD player. (Many schools also need a big
lead-acid battery and a DC-to-AC inverter for dealing with
intermittent electricity.) An obvious question is whether kids can
learn by just watching TV. The short answer is no. The longer answer
concerns pedagogy.
Put simply, "mediation-based pedagogy" refers to the need of
placing a teacher (or a "mediator") in between the students and the
TV. The mediator periodically pauses the video and engages the
students in various activities based on what has just occurred on
TV. These activities may include asking questions, inviting kids to do
board work, and organizing role-playing activities. The mediator's job
is to make his or her class as lively, dynamic, and interactive as the
one conducted by the model teacher on TV. In effect, the video and the
mediator form a "team:" the video provides an example, a framework, a
lesson plan, and a content and methodology model; while the mediator,
who may not be highly skilled in some domain-specific knowledge,
supplies the crucial interactive element.
Another variation of the theme is "peer-mediation," the approach of recruiting the brightest fellow students to serve as mediators during periods when the local teachers are absent, which are common occurrences in government schools in India. In our experience, the student mediators appear to universally display a high degree of responsibility and enthusiasm when they are put in charge.
The highly motivated teachers can also study the supplied videos
on their own, ahead of the live classes. Without DSH, such motivated
teachers do not have an effective means of self-improvement; with DSH,
a path is open to them as long as they are willing to work hard. This
path leads to a best-case scenario, when we end up "graduating" the
teachers, who may indeed choose to cast aside the live mediation
crutch and become more effective teachers in their own right. In
traditional teacher training workshops that last just a few days, the
short duration necessitates that the topics covered must be kept at an
abstract level, and it is not always clear how such abstract
principles should relate to many of the daily topics. In DSH, the
videos carried home by the participating teachers provide an ongoing
and highly specific training: the local teachers learn by observing
the best model teachers in action day-in and day-out, and they learn
by doing. So this mode of training has the potential of being much
more effective.
In short, the focus of DSH is not to replace people; instead, it is about amplifying the reach and the power of the relatively small number of the skilled teachers, and to train and empower the less skilled teachers. In this sense, DSH is foremost a "people system," not just a computer- or network-system.
