Effects of Practice Types on the Acquisition of English Phrasal Verbs

English phrasal verbs are ubiquitous and challenging for second language (L2) learners, particularly for those whose first language does not have an equivalent structure. This study investigates the facilitative role of three distinct L2 practice types in promoting English phrasal verb acquisition. Eighty first-year college students from China were randomly assigned to three groups: the continuation group, which was first presented with an input text and then required to complete it; the retrieval group, which was first presented with the input text and then required to engage in retrieval practice; and the trial-and-error group, which was first required to engage in trial-and-error practice before reading the input text. The effectiveness of these practice types was compared via both an immediate post-test and a 1-week-delayed post-test. The results showed that in the immediate post-test, the continuation group performed comparably with the retrieval group but outperformed the trial-and-error group. However, in the 1-week-delayed post-test, the continuation group significantly outperformed the other two groups. The findings revealed that the continuation writing task not only initially equips learners with declarative knowledge and subsequently closely integrates static L2 learning with dynamic idea expression but also enhances learners’ task self-efficacy, thereby optimally promoting phrasal verb learning and retention.
