Major concern as e-resource
developer… WHY? HOW?
• Today, English teachers of S/F language are
constrained to become familiar with emerging
learning technologies.
• Not only that, s/he has to use resources
prepared by other teachers, but also to
prepare his own e-resources and e-materials.

Key Issue….
• Well, the major problem is that it is not all
English teachers’ cup of tea.
• In such case what can be done???

Using existing software / programme /
web resources…
• The best of all idea is to use existing e-resources
available. These software are primarily prepared
for other purposes but can be utilized for ELL.
• So, if a teacher wants to improve writing skills of
the students, he can use MS Office - Word,
writeboard, blogger.com, orkut, face book,
moodle -LMS, wikieducator etc.
• If reading skills need to be improved, again above
mentioned e-resources can be effectively utilized.

From LSRW, LS skills and available
resources…
• So far as RW skills are concerned, available
resources can be of immense help to teachers.
• But the million dollar question is ‘how to
how
make effective use of available e-resources
e-
for LS skills’??
• B’coz listening and speaking skills are
different than the other two skills it needs to
be given special attention.

Available LS skill development material
and its disadvantage…
• Most of Listening materials used in the class
of ESL/EFL are developed by native speakers
speakers.
• These western courseware are designed to
meet general purposes and therefore cannot
address needs of learner in specific context.
• Often they are culturally biased (Supiyan,
1996).

Preparing LS skill material and its
advantages…
• If listening skill material is developed by the
teacher looking at the level of students and
context, it contributes to skill development.
• Studies have reported that learners respond
to computer aided / mediated teaching
learning materials produced by their own
teachers more effectively than prepared by
other agencies (Bloomer, 1985).

But how to do it??
Is it easy to do it??
Can all teachers do it ??
• Here again, the teacher need not sit with the
programmer to prepare programme/software.
• S/He just has to use some existing software or
download some open-source sound editing
programme and learn the basics to operate it.
• It is as easy as child’s play: - Record, Edit and
Play…
• And see how wonderfully you can teach your
students the most useful skills – listening and
speaking.
