Using chunks is said to bring about fluency into speech as they save speakers from constructing their speech upon a word-by-word basis. Particle phrases (A term coined in this study to refer to phrasal verbs and their derived and deviated nouns and adjectives) are also among those chunks. This study seeks to see whether memorizing them will affect EFL learners' spoken fluency. To this end, 51 Persian speaking participants (37 females, 14 males) who were selected from 3 intact classes based on their performance in narrative video-based retelling constituted the sample of the study. The study was a quasi-experimental one in design because of the non-random assignment of the participants into either of the experimental and control groups. They were assigned to three groups: two experimental and one control. Both experimental groups received the same instructions on metaphorical concepts of particles (out, off, etc.) in the 150 phrasal verbs available in Garnier and Schmitt’s (2015) frequency list. They both engaged in self-generated contexts except that those in the first came up with hands-on task of drawing sketches, too. The control group, however, received none of the above treatments. The results of a one-way ANOVA procedure in the immediate post-test indicated that the participants in the first experimental group significantly outperformed not only the control group, but also the second experimental group that made more relative gains than their counterparts in the control group. The outperformance of the first experimental group was also found in the delayed post-test, which represented the long-term effects of the methods. The findings suggest several implications for this vital but surprisingly neglected issue of engaging students with self-generated sketches.
