Abstract:
It is claimed that the teaching of English as a second language, in the post-independent
era of Sri Lanka, even with the adoption of four methodologies - Grammar translation,
Direct method, Audio-lingual method and Communicating language teaching - in
succession, could not make any difference in the standard of English of the school goers.
In the backdrop of these developments, the introduction of content based instruction, in
the science stream of the G.C.E. A / L classes, is a paradigm shift, for it not only changed
the medium of instruction, but also charged the subject specialist with the mission of
improving the standard of English of the student population, hitherto confined to
professional English teachers.
The research study on the Issue of Change of Medium to English and the Problems
Encountered by the Students in Learning at the G.C.E. Advanced Level classes was,
therefore, undertaken with the main objective of identifying the problems that the
students currently face in their pursuit.
The research methodology adopted was purposive sampling, for the content based
instruction, in the science stream of the G.C.E. A / L classes is largely confined to
Colombo schools. Moreover, the purposive sampling ensured the representation of all
ethnic groups and both genders in the sample.
The study brought out three major shortcomings in the practice of content based
instruction, in the science stream of the G.C.E. A / L classes: the lack of scaffolding in
overcoming students' difficulties in transition from mother tongue medium to the
medium of English; the lop-sided nature of in-service teacher training programme and its
/mp/ications in the classroom practices; and the non availability of an officially declared
criterion profile to evaluate the answer scripts of the student, in the science stream of the
G.C.E. A / L classes, in the medium of English.
V
The study suggests an institutionalization of a mechanism of scaffolding to assist the
students in transition from mother tongue medium to the medium of English in the
Science stream of the G.C.E. A / L classes; the streamlining of the in-service teacher
training programme, with a suitable curriculum on the theories and practice of content
based instruction, and with a suitable follow up to monitor the benefit of the in-service
teacher training programme at school level; and the declaration of an officially
proclaimed criterion profile, in order to guide the teachers of content based instruction to
evaluate the answer scripts of their students in the science stream of the G.C.E. A /L
classes, in keeping with the aims and the objectives of content based instruction.
