This study investigated relationships between individual learner differences and the learning of two English structures that differed in their grammatical difficulty. Using a quasi-experimental design, 66 secondary-level learners of English as a foreign language from three intact classes were provided with four hours of instruction on two L2 structures –one considered relatively easy to learn (i.e., past progressive) and the other relatively difficult to learn (i.e. passive construction). The participants were pretested on their knowledge of both structures and posttested immediately after the instruction. Learners’ progress was measured via written grammaticality judgment tests (GJT) and oral production tasks (OPT). The instruments to measure individual learner differences included a computerized language aptitude test, an L1 metalinguistic awareness test, a motivation questionnaire, a backward digit span test, and a learner retrospection questionnaire.
The results revealed that aptitude and motivation were the two variables that significantly contributed to learners’ gains with respect to the ‘passive’ and that L1 metalinguistic awareness explained significant variation in learners’ gains regarding the ‘past progressive’. These relationships were observed with learners’ performance on the written but not oral measures. A detailed analysis of the aptitude test components revealed that the grammatical inferencing subtask was significantly related to L2 gains on the ‘passive’ – again only with respect to learners’ performance on the written GJT. The results also revealed that learners with different aptitude profiles (i.e., low, medium, high) benefited differently from instruction on the two target features. High aptitude learners performed better than low aptitude learners on the ‘passive’ as measured by the GJT posttest. With respect to the ‘past progressive’ only learners in the medium aptitude profile group improved significantly on the written GJT.
These findings confirm that language aptitude holds a role in language learning but that there are other factors (i.e., motivation and L1 metalinguistic awareness) that also contribute to L2 progress. These results also provide evidence from a classroom-based study that the grammatical difficulty of what is to be learned is a factor in determining what cognitive abilities L2 learners rely on in their efforts to learn a new language.
