This multisite study replicates Webb, Newton, and Chang's (2013) study on the effect of repetition on incidental learning of multiword units (MWUs). Even though more researchers have started to investigate MWUs, most data have been collected from university students. Furthermore, the large effect of MWU repetition on learning reported by Webb et al. has not yet been corroborated. Data in our study were collected from two university samples (EFL students in Poland and Flanders) and one nonuniversity sample (Flemish EFL learners in secondary schools). Unlike Webb et al., we adopted a counterbalanced within-participants design. Participants read and listened to a modified graded reader in which target MWUs occurred 1, 5, 10, or 15 times. In line with the initial study, we found a positive effect of repetition. However, the learning gains were smaller, and the number of repetitions needed was different. The findings were consistent across the university and nonuniversity samples. The study concludes with a discussion of these findings in relation to both pedagogical implications and the benefits of multisite replication research.

多词单元的重复和附带学习：Webb、Newton 和 Chang 的概念性多站点复制研究 (2013)

这项多站点研究重复了 Webb、Newton 和 Chang (2013) 关于重复对多词单元 (MWU) 附带学习的影响的研究。尽管越来越多的研究人员开始调查 MWU，但大多数数据都是从大学生那里收集的。此外，Webb 等人报告了 MWU 重复对学习的巨大影响。尚未得到证实。我们研究中的数据是从两个大学样本（波兰和佛兰德斯的 EFL 学生）和一个非大学样本（中学的佛兰德斯 EFL 学习者）收集的。与 Webb 等人不同，我们采用了参与者内部平衡设计。参与者阅读并聆听修改后的分级读物，其中目标 MWU 出现 1、5、10 或 15 次。与最初的研究一致，我们发现重复具有积极的作用。然而，学习收获较小，所需的重复次数也不同。大学和非大学样本的研究结果是一致的。该研究最后讨论了这些发现的教学意义和多站点复制研究的好处。
