Incorporating language structure into a communicative task: An analysis of the language component of a communicative task in the LINC Home Study Program

The purpose of this talk is to present the results of the analysis of a task included in the LINC Home Study (LHS) program. LHS is a federally funded distance education program offered to newcomers to Canada who are unable to attend regular Language Instruction for Newcomers to Canada (LINC) classes. For the purpose of this talk, a task is selected from one instructional Module of LHS that was offered as a demonstration Module for the general public. In this task, a language structure (a gerund) is selected and analyzed. Specifically, the analysis presented in this paper focuses on how language structure is integrated into the task. The integration of language structure into the task is assessed against the criteria outlined in the Task-Based Language Teaching and Learning (TBLT) literature and the Canadian Language Benchmarks (CLBs) guidelines. The analysis of this task demonstrates that the presentation of language structure in the task violates the main principle of a meaning-based approach to second language teaching (i.e. TBLT) that emphasizes the primacy of meaning over language forms. This paper calls for more research on LHS considering the fact that LHS is a national program that is identified as one of the Best Practices in Settlement Services language programs.

Positive Interactions in Variable Systems: Evidence for Constraint Scaling Factors in Phonology


Language systems characterized by high levels of variability offer unique possibilities for probing the structure of the phonological grammar.  This talk draws on data from developing L1 phonologies and loanword adaptation patterns to argue that marked structures within words interact in a positive fashion.  As the probability of accurate realization for one marked structure increases, so too does the probability of accurate realization for additional marked structures within the word.

Two case studies are presented.  The first case study looks at words that contain multiple sources of syllable-structure markedness, focusing on data from the twelve Dutch-acquiring children in the CLPF corpus (Fikkert 1994, Levelt 1994).  The overall finding is that accurate realization of marked coda structures increases the probability that marked onset structures will be accurately realized by the child.  These effects cannot be reduced to either age or the frequency with which the marked structures are attempted.  The second case study examines the realization of marginal segments in a corpus of Québec French borrowings from English (Roy 1992), and finds evidence for similar positive interactions at the level of segmental realization.

I argue these positive interactions are best modeled through scaling of constraint values within a probabilistic weighted constraint grammar – either Noisy Harmonic Grammar (Boersma & Pater 2008) or Maximum Entropy OT (Goldwater & Johnson 2003). Constraint scaling factors co-exist with basic constraints weights, and can be keyed both to grammatical factors like prosodic position, and to non-phonological factors like word frequency and attention.  The result is a model that captures the attested interactions between marked structures within words while avoiding the pitfalls of previous accounts that are too restrictive to accurately model the full range of variation.
