This paper reports a mixed-methods study that explored the strategy use of a cohort of Chinese as second language learners in mainland China from the perspective of mediation theory. Data sources include a questionnaire survey (N = 189) and a semi-structured interview (N = 12). The findings revealed that the participants orchestrated a repertoire of language learning strategies and frequently used social and meta-cognitive strategies. Analysis of the qualitative data suggested that the participants' strategy use was shaped by the learners' self agentic power (their beliefs and Ideal L2 self), and the socio-cultural environment. Specifically, their strategy use was mediated by a host of socio-cultural factors, including learner beliefs, social agents, cultural artifacts, and learning environment. Considered together, the findings illuminate the socially situated nature of the use of language learning strategy. That is, strategy use of the participants stems from the interplay of learner agency and socio-cultural factors. The findings also imply the necessity of strategy-based instruction and highlight the importance of a Chinese-speaking environment for Chinese learning.

It has been proposed that children differ from adults in that children license a conjunctive inference to disjunctive sentences that lack any licensing expression. The proposal is that children infer “A and B” from sentences of the form “A or B.” Although children’s conjunctive interpretations of disjunction have been reported in some studies, they have not been observed in other studies. This study investigates one possible source of the different findings, which is the presence or absence of objects that are contextually introduced, beyond those mentioned in the test sentences. Using a Truth Value Judgment Task, we conducted three experiments with preschool Mandarin-speaking children and a control group of adults. Test sentences in Experiment 1 included disjunction and a deontic modal verb, and the contexts only included objects that were mentioned in the test sentences. In Experiment 2, the deontic modal verb was omitted from the test sentences. Experiment 3 presented the same sentences as Experiment 2, but the contexts included additional objects beyond those mentioned in the test sentences. Both children and adults assigned a conjunctive inference to the test sentences in Experiment 1. In Experiment 2, with no deontic verbs and no contextually introduced objects, a subset of children computed conjunctive inferences, whereas none of the adults did. In Experiment 3, neither group made a conjunctive inference. The findings reveal that entities in nonlinguistic contexts influence children’s understanding of logical expressions. Moreover, preschool children already have linguistic knowledge that modal verbs license conjunctive inferences for sentences with disjunction.

In sentences with internal negation, Free Choice Inferences (FCIs) are canceled (Chierchia, 2013). The present study investigated the possibility that FCIs are negated, not canceled, by external negation. In previous research, both Mandarin-speaking children and adults were found to license FCIs in affirmative sentences with a modal verb and the disjunction word huozhe ‘or’ (Zhou et al., 2013). The present study contrasted internal versus external negation in sentences that contained all the ingredients needed to license FCIs. Four experiments were conducted using the Truth Value Judgment Task (Crain and Thornton, 1998). Experiment 1 tested Mandarin-speaking children and adults using sentences with internal negation, a modal verb and disjunction. As expected, children did not license FCIs; rather, they assigned a ‘neither’ interpretation to disjunction. Also as expected, adults analyzed disjunction as taking scope over internal negation, yielding a ‘not both’ interpretation (Jing et al., 2005). Experiment 1 provided the benchmarks for sentences with external negation in Experiments 2-4. Experiment 2 confirmed that English-speaking adults distinguish between internal and external negation in sentences with disjunction. In Experiment 3, external negation was conveyed by the focus adverb zhiyou ‘only’. External negation eliminated the between-group differences observed in Experiment 1. Both children and adults analyzed external negation as taking scope over disjunction. Experiment 4 tested the effect of external negation on the computation of FCIs. The test sentences only differed from Experiment 1 by using external negation, rather than internal negation. Again, children and adults interpreted the test sentences in the same way. Most importantly, in contrast to Experiment 1 (with internal negation), both groups analyzed external negation as negating, rather than canceling, FCIs. The findings support the distinction between internal and external negation.

Teacher identity formation provides a direction for the development of autonomy (Huang & Benson, 2013). However, the process of identity formation is complex and how this process influences teacher autonomy has not been sufficiently studied. To contribute to knowledge in this field, the present study investigated the relationship between teachers’ attitudes toward teacher identity and teacher autonomy. We first observed 14 Chinese College English teachers’ classroom teaching. Following that, we conducted stimulated recall interviews with all the teachers to pinpoint their autonomous practices. Finally, we conducted semi-structured interviews to investigate these teachers’ attitudes toward their identities. One of the main findings was that the teachers who held a positive attitude toward their professional identity were more autonomous in their teaching practices than those with a negative attitude. The findings invite us to conclude that teachers’ attitudes toward their professional identity are positively associated with teacher autonomy.
