Abstract (EN):
The present study investigates the effects of delivery mode in adult EFL
courses by comparing a) languaging, the “process of making meaning and shaping
knowledge and experience through language” (Swain 2006: 98) and b) learning in
three settings that are representative of common course delivery modes: i) face-to-face
group classes; ii) one-to-one private tutoring sessions; and iii) individual online
courses. Conducted within a Vygotskian (1978, 1987) sociocultural framework, data
for this quasi-experimental study include recordings of pairwork in group classes and
of tutor-learner interaction in one-to-one classes, and also think-alouds of individuals
in online courses, thus drawing on Vygotsky’s concept of inner speech and more
recent work on self-scaffolding (Holton & Clark 2006; Knouzi, Swain, Lapkin, &
Brooks 2009). The analysis is a mixed-methods approach of microgenetic qualitative
analysis of learner talk and quantitative analysis of LRE number, focus, resolution and
engagement, and includes questionnaire responses and scores from post-tests.
Findings indicate that languaging, evidenced in Language-Related Episodes
(LREs), occurred in all three modes. While individuals in the online mode produced
significantly fewer LREs than learner-learner dyads in group classes or learner-teacher
dyads in one-to-one tuition, online individual numbers were similar to LREs initiated
by each learner in learner-learner dyads, suggesting individuals identified language
problems with a similar frequency as their group counterparts. Learner-learner dyads
in group classes and one-to-one learner-teacher dyads produced similar numbers of
LREs, but one-to-one episodes were more closely associated with learning than group
or individual LREs, as observed in instances of microgenetic development and posttest responses. This may be because one-to-one episodes were better quality in terms
of correct resolution and greater resolution by the learner, rather than the teacher. In
one-to-one, resolutions followed scaffolding in the form of elicitations and prompts
contingent on learners’ tentative responses and teachers’ perceptions of learners’
current knowledge. Such teacher guidance towards learner resolution may have made
outcomes more memorable for subsequent post-test recall. Regarding LRE focus, dyads produced more grammar LREs than online
individuals, which may relate to habitual grammar-focussed learning practices of faceto-face classrooms, whereas one-to-one dyads focussed more on spelling, suggesting teachers sensed their role was to correct learners’ written language. Regarding LRE
resolution, proportions of correctly resolved episodes were similar between group and
online individual modes, although the individual proportion was based on fewer
LREs, suggesting individual learners did not initiate episodes they would be unable to
resolve. The extent to which LREs were characterised by limited engagement
(linguistic preferences were stated without further deliberation) or elaborate
engagement (there was evidence of a cognitive self-regulation strategy) did not differ
significantly between modes. In learner-learner interaction in group mode, the
prominence of LREs characterised by limited engagement in one learner and elaborate
engagement in the other suggested it was unnecessary for both participants to be
elaborately engaged for episodes to be languaged and resolved.
Learners across modes averaged post-test scores of 70% to 80% of items
resolved in agreement with LRE resolution in the task, suggesting associations
between languaging and learning.(...)
