Abstract

Instructed second language (L2) research has frequently addressed the effects of spacing, or, alternatively, the distribution of practice effects. The present study addresses Rogers and Cheung’s (2021) concerns about the ecological validity of such work via a natural experiment (Craig et al., 2017). Learners’ self-determined exposure and in-app behavior were examined in relation to language gains over time. Duolingo learners of Spanish or French (N = 287) completed a background questionnaire, scales measuring L2 motivation and grit, and two tests of L2 proficiency before and after a six-month period of user-controlled app usage. Total minutes of app exposure exhibited a correlation with written but not oral proficiency gains. More dependable correlates of gains were frequency- and curriculum-oriented measures. Additionally, L2 grit and motivation were weakly to moderately correlated with several in-app behaviors. We conclude with implications for how apps can best be leveraged to produce L2 gains.

频率、持续时间和强度对多邻国外语学习的影响

指导性第二语言（L2）研究经常涉及间距的影响，或者说，实践效果的分布。本研究通过自然实验解决了Rogers和Cheung（2021）对此类工作的生态有效性的担忧（Craig et al.，2017）。随着时间的推移，研究了学习者的自主暴露和应用内行为与语言习得的关系。双语西班牙语或法语学习者（N = 287）完成了一份背景问卷、测量二语动机和毅力的量表，以及在用户控制的应用程序使用六个月前后的两次二语熟练度测试。应用程序暴露的总分钟数与书面能力的提高相关，但与口语能力的提高无关。更可靠的收益相关性是以频率和课程为导向的衡量标准。此外，第二语言的毅力和动机与一些应用内行为呈弱到中度相关。最后，我们对如何最好地利用应用程序来产生L2收益提出了建议。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
