内容简介
For decades, researchers in the field of second language acquisition have examined the relationship between individual differences, such as aptitude and motivation, and second language (L2) achievement. These efforts have led to a body of empirical work that is vast and diverse in terms of settings, samples, instruments, and outcomes. This talk will attempt to make sense of this domain by examining the core relationships of interest through the lens of meta-analysis (i.e., a systematic approach to synthesizing findings across a body of empirical studies). More specifically, after situating individual differences in the context of SLA, I will present an overview of meta-analytic findings on a range of individual differences as they relate to L2 achievement. I will also discuss when and why those relations have been found to vary across different methodological and substantive features.

内容简介
Research on language learner psychology relies heavily on surveys. Such instruments can be very useful for measuring latent (non-observable) variables such as motivation, anxiety, and grit. They are also popular among researchers because they can be designed in a relatively short amount of time. However, developing psychometrically sound scales for measuring individual difference variables is actually quite challenging and requires great care if we want the measure to yield high-validity data for a given study. This talk will go over some of the major considerations—both conceptual and practical—in designing and developing scales for measuring learner individual differences. Recent examples from L2 research will be used to illustrate the points be made throughout.
