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.

Students with attention disorders face many challenges in the educational process, which also affects their academic future. The goal of this study was to compare the effect of the Cup Stacking Method and Transcranial Direct Current Stimulation on the working memory and information processing rate on students with attention deficits. The research population included all fifth and sixth grade students in public schools in Tehran in 2019-2020. Forty-five students with attention deficit were purposefully selected and then randomly divided into three groups of 15: Transcranial Direct Current Stimulation; Cup Stacking; and Control groups. The Transcranial Direct Current Stimulation group was given a 10-session therapeutic trial; a 30-minute cup stacking game was played for 10 sessions by the second group. The Symbol Digit Modalities Test and the Digit Span subtest were used to assess the study variables. The results of mixed variance analysis showed that although both cup stacking and Transcranial Direct Current Stimulation improved the information processing rate and working memory of students with attention deficit, the two methods did not have a significant difference in their impact on these functions of the research subjects. It is recommended that school teachers use cup stacking in their daily interaction with the students, and that clinical professionals use Transcranial Direct Current Stimulation to address executive function issues.
