Morpheme studies
The masterminds behind morpheme studies are Dulay and
Burt. They fashioned a scoring scheme that awarded different point values depending
upon whether a morpheme was correctly supplied in an obligating context,
occupied but not well formed, or omitted altogether. They applied this scheme
to their “subjects” “speech” by Bilingual Syntax Measure (BSM). Their
research is an approach to the study of a learner’s competence in a language;
based on the study of a learner’s total linguistic performance (i.e. what the
learner is able to say and do is the language and not just the learner’s
errors.
