The effect of synchronous computer mediated communication on language acquisition

进行了两项研究。Hughes(2022)回顾了过去十年中关于基于文本的同步计算机中介交际(TSCMC)在二语习得(SLA)中的39项研究。研究发现，TSCMC对二语习得有积极的影响，但在学习者-学习者对话中缺乏一些假设的促进语言习得的互动特征。Hughes(2023)通过实验比较了TSCMC和非交际性计算机辅助语言学习，发现虽然两组在统计上取得了相同的收益，但TSCMC组实现了这些收益，但输出明显较少，表明TSCMC组在学习效率方面具有优势。综上所述，TSCMC对二语习得有显著的积极作用，但这种作用背后的机制还有待进一步研究。

Two studies were conducted. Hughes (2022) reviewed 39 studies on text-based synchronous computer-mediated communication (TSCMC) in second language acquisition (SLA) over the past decade. It found a positive effect of TSCMC on SLA, but some features of interaction hypothesized to promote language acquisition were lacking in learner-learner dialogues. Hughes (2023) experimentally compared TSCMC with non-communicative computer-mediated language learning and found that, while both groups achieved statistically equivalent gains, the TSCMC group achieved those gains with significantly less output, indicating an advantage in learning efficiency. In conclusion, TSCMC has a significant positive effect on SLA, but the mechanism behind that effect requires further investigation.
