Vocabulary recall

One of the most important needs in learning a second or foreign language is vocabulary acquisition. Certainly, failure to keep vocabulary in mind is a problem for both typically-developing learners as well as those with a learning disability (LD). This language demand requires teachers to use techniques in order to reinforce vocabulary recall. The current study is an attempt to investigate the effect of two post-teaching vocabulary learning techniques of diglot-weave and cooperative learning on vocabulary knowledge of LD students and to compare them with the common instruction of picture-word definition. To this end, 90 Iranian female LD students from 10 intact classes in two Junior Exceptional Schools in Shiraz were randomly assigned to one of the three groups. After the intensive teaching sessions, the test was administered to examine their vocabulary recall performance in each group and after a two-week interval, the same test was used to examine their vocabulary retention. The results by conducting the one-way ANOVA indicated that both experimental groups of diglot-weave and cooperative learning techniques outperformed the control group of picture-definition in the vocabulary recall and retention tests. However, there was no significant difference between the performance of diglot-weave and cooperative learning groups. Therefore, the findings of the present study could provide useful implications for foreign language teaching programs particularly in Special Education and students with LD.

Given the role of lexical knowledge in language learning, strategies for vocabulary learning should be paid more attention in the literature. This study investigated the effects of visualization, drawing, and memorization on Iranian EFL learners' recall and retention of second language vocabulary using a quasi-experimental comparison design . To that end, three intact classes, incorporating sixty students in total , were randomly selected as the experimental groups of this study. Nation’s (2006) vocabulary size test was administered to them to homogenize them in terms of English lexical knowledge. The results of one-way ANOVA demonstrated that there were no significant differences among the three groups in terms of vocabulary knowledge. A piloted researcher-made vocabulary test was administered to the participants as the pretest and post-tests. The one-way ANOVA results showed that there were no significant between-group differences among the groups' performances on the immediate and delayed posttests. However, the results of a repeated-measures ANOVA indicated that the three strategies had a significant within-group effect on the three groups' vocabulary recall, while their vocabulary retention was found to have dropped significantly from immediate to the delayed posttest. All the same, the drawing group had the best performance from the pretest to the immediate posttest, and the control group was the weakest on delayed posttest. Finally, the findings are discussed, and implications are offered for EFL teachers and learners.

English for Specific Purposes (ESP) education has gained prominence as a specialized field designed to address the distinct linguistic needs of learners. Although AI-enhanced instruction has been investigated within general English language learning, its implementation in ESP contexts particularly concerning vocabulary recall and retention has remained insufficiently explored. This study sought to evaluate the impact of AI-supported instruction on vocabulary recall and retention among Iranian ESP learners. Based on non-random convenience sampling, a total of 48 undergraduate students in an ESP course from a university in a southeastern province in Iran participated in the present quasi-experimental study. The participants were non-randomly assigned into two different groups: an experimental group (n=24) receiving AI-powered vocabulary instruction through Diffit, and a control group (n=24) receiving traditional print-based vocabulary instruction. Data were collected during a twelve-week intervention through AI-powered instruction of ESP vocabulary. To address the research questions, a univariate repeated measures analysis of covariate (ANCOVA) was employed. Findings revealed that AI-enhanced instruction significantly improved vocabulary recall and retention among ESP learners. The results offer robust evidence supporting the efficacy of AI-based instructional approaches in enhancing vocabulary learning outcomes within ESP settings.
