Hundreds of millions of language learners around the globe study a second language with popular apps such as Duolingo, Rosetta Stone, Busuu, and Babbel. This study examined the effectiveness of one app, Babbel, for developing both receptive linguistic knowledge of vocabulary and grammar, as well as oral communicative ability in Spanish as a second language. Fifty‐four English speakers not enrolled in Spanish classes studied Spanish on Babbel over the course of 12 weeks, with a goal of studying roughly 10 min per day. Participants completed pretests and posttests, and provided data on their motivation to learn Spanish and use Babbel. Results showed that learners were able to develop grammar and vocabulary knowledge as well as oral communicative ability. The amount of Babbel study time was the strongest predictor for all three measures, with motivation to learn Spanish also significantly predicting growth in oral communicative ability.

基于应用程序的语言教学对培养接受性语言知识和口语交际能力的有效性

全球数以亿计的语言学习者使用 Duolingo、Rosetta Stone、Busuu 和 Babbel 等流行应用程序学习第二语言。本研究检验了一款名为 Babbel 的应用程序在培养词汇和语法的接受性语言知识以及西班牙语作为第二语言的口头交流能力方面的有效性。54 名未参加西班牙语课程的英语使用者在 12 周内在 Babbel 上学习西班牙语，目标是每天学习大约 10 分钟。参与者完成了前测和后测，并提供了有关他们学习西班牙语和使用 Babbel 的动机的数据。结果表明，学习者能够发展语法和词汇知识以及口语交际能力。Babbel 学习时间是所有三个指标的最强预测因子，
