Retention

Most of the studies on the key word method of second/foreign language vocabulary learning have been based on the evidence from laboratory experiments and have primarily involved the use of English key words to learn the vocabularies of other languages. Furthermore, comparatively quite limited number of such studies is done in authentic classroom contexts. The present study inquired into the effect of using mnemonic key word method of vocabulary instruction on the learning and retention of vocabulary over long term in a normal EFL classroom context.Fifty5th grade primary school students were selected and randomly assigned into experimental and control groups. The experimental group received vocabulary instruction using mnemonic key word method and the control group received classic memorization based instruction of the same vocabulary items. The two groups took three posttests a day, two weeks, and a month after the last treatment session. A MANOVA analysis was run on the data and the results indicated that subjects in the key word group outperformed the memorization group at a significant level in both their learning and retention of the newly learnt vocabularies. The results of the study underscore the efficacy of the establishment of mental links and images for the vocabulary learning and retention of novice and beginning level EFL learners. It further implies that mnemonic devices like key word method should be given prompt attention by both EFL material developers and practitioners as a potentially effective strategy for vocabulary teaching, learning and long term retention at the early stages of second or foreign language development.

The environmental crisis is increasing today and this makes it imperative for people more than ever to expand their understanding of the environmental concepts. Accordingly, films can be an effective tool to do that, but finding the right medium is a matter of debate. Needless to say, different forms of films have different effects. Within the same line, the current paper aims to test out the effectiveness of narrative and non-narrative documentary films on the learning and retention of the environmental concepts. The research method was quasi-experimental, administering a pre-test and a post-test on 20 male and 20 female participants between 20-27 years old. The samples were randomly categorized into two groups. Both groups had an equal number of participants who did not have any earlier  environmental activities and their majors were not related to environment and natural resources studies. They were from a variety of educational backgrounds. The groups were homogenous in terms of GPA, too. Firstly, the pre-test was administered to both groups. One group watched a narrative documentary on environmental and natural resources for 8 weeks, while the other group watched the non-narrative version of the same film for the same period. Then, a learning and retention test was given to both groups. The MANCOVA test was administered on the data and the findings showed a significant difference between the two groups in terms of learning and retention. It was concluded that narrative films can have a more significant effect on the learning and retention of the variables.

This study investigates the effect of four types of oral corrective feedback, namely, explicit elicitation, implicit elicitation, explicit recast and implicit recast on the most commonly mispronounced phonological features among Iranian EFL learners through immediate uptake and retention. Five classes were randomly categorized into four experimental groups and one control group, each with 18 intermediate-level male learners. The treatment was conducted in the form of a retelling task in nine sessions. During the feedback sessions, the learners’ uptake was recorded. The learners’ retention was also perused in one immediate and one delayed post-test. The results revealed that those learners who received explicit recast obtained the highest score in terms of correct uptake, and that the groups performed differently across different time periods. The learners’ scores enhanced over time; however, the increase then leveled off and even dropped in the delayed post-test in all the experimental groups except for the group which received explicit elicitation, apparently leading to more retention of the target phonological features. The study offers insights to teachers regarding the effect of recast and elicitation in their explicit and implicit form on L2 pronunciation.

Given the vital role that vocabulary plays in learning a language along with the fact that sense-induced emotions are noteworthy due to their influence on cognition, this study examined the impact of emotioncy-based language instruction on the long-term memory (LTM) vocabulary retention of Iranian EFL learners. To this end, 32 participants were selected based on their level of trait/state anxiety, working memory span, language proficiency, neophobia, and emotioncy towards the selected words to be instructed. Two weeks after the instruction session, the participants were given a retention test. To compare the mean scores of each participant exposed to the three emotioncy-based language instruction conditions (i.e., avolvement, exvolvement, and involvement), a one-way repeated measures ANOVA was employed. The results showed that the participants outperformed in recalling the words that were taught through the involvement level of the hierarchy of the emotioncy model in comparison to those taught through the exvolvement level as what is currently practiced in language classrooms. Finally, drawing on the concepts of emotioncy, emo-sensory quotient, embodied cognition, and multisensory learning, the study elaborates on the value of senses in evoking emotions conducive to cognition and memory enhancement. After all, the study suggests that senses act as the main gears that stimulate the evocation of certain emotions, and the resultant emotions shape cognition, resulting in better LTM retention of vocabulary items.

It is widely acknowledged that collocations play a crucial role in second or foreign language learning by enabling learners to know more about language chunks and lexical strings. Although many studies have examined L2 learners’ collocational competence, comparatively less research has been carried out to probe into the effective instruction and exercises for enhancing the acquisition, retention, and production of lexical (e.g. make a mistake ) vs. grammatical ( on purpose ) collocations. Therefore, the present study attempted to explore the effect of L2 definitions, fill-in-the-blanks, and sentence writing exercises on the acquisition, retention, and production of lexical vs. grammatical collocations. The data were collected from 66 EFL participants who were studying English at a private language institute. First, an Oxford Placement Test (OPT) was given to homogenize the learners. Then, the participants were divided into three groups, each receiving one of the three different types of exercises including definitions, fill-in-the-blanks, and sentence writing exercises. Data analysis using multivariate ANOVA (MANOVA) indicated that learners who received the sentence writing treatment significantly outperformed those learners who received definition and fill-in-the-blank exercises in the acquisition, retention, and production of lexical vs. grammatical collocations. Moreover, fill-in-the-blanks could help the participants learn, retain, and remember both types of collocations significantly better than the L2 definitions. These findings have some pedagogical implications for learning and teaching lexical and grammatical collocations.

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.

This study aimed to investigate the effect of oral and written contextualization of collocation teaching on the learning and long-term retention of semantically semitransparent collocations by Iranian EFL learners. To this end, 65 students were selected from a cohort of students who were studying English at an English language institute in Sanandaj, Iran. They were randomly divided into two groups based on whether they would receive oral and written contextualization. Then, each group was further subdivided into two groups based on whether they would receive instruction on the concept of semantic transparency, yielding two experimental groups each including 16 learners as the Written Practice Group plus and minus instruction on the concept of semantic transparency, two experimental groups as the Oral Practice Group plus and minus instruction on the concept of semantic transparency, including 16 and 17 learners, respectively. Their initial general English proficiency was measured through the Preliminary English Test (PET), and they were pretested on semitransparent collocations through a researcher-made collocation test. Finally, two equivalent researcher-made collocation tests were used to measure the participants’ learning and retention on the immediate and delayed posttests. The results of two-way ANOVAs revealed that the oral group outperformed the written group on the immediate and delayed posttests and the plus transparency instruction groups in each modality (oral and written) group outperformed the minus transparency instruction groups. The interpretations of the findings and their pedagogical implications have been discussed.

With the rapid development of technology, multimedia comes into English classes and positively improves learners’ language proficiency. The present study attempted to consider the use of animated infographics on the vocabulary gain and retention of Iranian intermediate EFL students. The classes were held online through the Jitsi meet website in the autumn of 2021. To this end, 60 EFL students were selected among 90 students through a homogeneity test. At the beginning of the treatment period, a pretest was administered to both groups, and then, the participants attended 13 sessions. In these sessions, the animated group (AG) was taught through animated infographics, while the control group (CG) was instructed conventionally. The posttest and delayed posttests were administered to test the student’s vocabulary gain and retention. The findings indicated that the AG outperformed the CG significantly in the posttest and delayed posttest. Therefore, the animated infographics proved to be more effective in learning English vocabulary for these students. The results could have implications for teachers because it heightens their understanding of using technologies in general and animated infographics in particular and leads to more effective teaching methodologies.

Poor vocabulary retention is one of the major difficulties experienced by English as a foreign (second) language (EFL/ESL) students. To tackle this problem, the current study explored the impacts of the modified visual input and the modified oral input on the short-term and long-term vocabulary retention of Iranian EFL students and their perceptions regarding implementing these two types of input in their classes. The initial population consisted of 90 male and female students from Islamic Azad University, Science and Research Branch in Tehran, Iran. The convenience sampling method was implemented to select the participants. After administering the Oxford Placement Test (OPT), 60 students were chosen to serve as the participants, and they were randomly divided into two groups of 30 learners, namely the experimental groups A and B, which received instructions based on the modified visual input and the modified oral input, respectively. Later, the participants received ten 60-minute treatment sessions. Next, the learners' short-term vocabulary retention was assessed using the same vocabulary test as the posttest. One month later, the same test was given to students to check their long-term vocabulary retention as the delayed posttest. The results showed that the two types of input had significant impacts on the vocabulary short-term and long-term retention of the Iranian EFL students to varying degrees. Moreover, the qualitative findings indicated that the learners adopted a significantly positive view toward implementing oral and visual input modifications in their classes. In the end, the implications of the study are provided.

Acknowledging the critical role of working memory in language acquisition, this study examines the effects of multimodal input enhancement on working memory capacity (WMC) and collocation learning in adolescent and adult EFL learners. A cohort of 117 participants was randomly assigned to either experimental groups, receiving enhanced textual and auditory inputs, or control groups, experiencing standard inputs. Assessments included the Preliminary English Test, n-back test, and immediate and delayed collocation posttests. The results indicated that multimodal input significantly improved WMC and the recall and retention of collocations for all learners. Adolescents, in particular, excelled in both immediate and delayed tests and adapted their WMC more effectively in a multimodal context than adults. Additionally, an interaction between age and WMC was noted, affecting collocation recall and retention. These findings affirm the benefits of multimodal materials in enhancing cognitive functions and memory resources, thus improving language learning. The study offers practical insights for educational practices, advocating for the use of varied modalities in teaching materials to cater to different learning styles and cognitive needs. It also highlights the significance of designing age-appropriate materials and managing cognitive load in curriculum development, providing a tailored approach to language education for diverse learner populations.
