We developed a method for efficiently quantifying communicative
orientations in accordance to the language teaching observation scheme
COLT part B (Spada & Fröhlich, 1995) by means of integrating transcripts
and features in tabular format. The drawback of COLT part B is that
reviewing a lesson in order to plan for the next is impractical because
recordings of lessons must be transcribed. Spada and Fröhlich's time
sampling procedure reduces time at the expense of skipping some transcripts
and ignoring some schematic features. Our method maximizes transcript
coverage. Tab and line-feed characters inserted within the transcripts allow
spreadsheet applications to tabulate utterances and turns along with their
speaker tags. Numerically coding of verbal interaction features provides
frequency counts of verbal interaction features by speakers or utterances. All
episodes in every turn are reflected in the analyses. Evaluation experiments
of our method suggest that, compared to literal coding representations,
transcribing lessons in our format covers more phenomena in less time.
