Investigating the Relationship between the Morphological Processing of Regular and Irregular Words and L2 Vocabulary Acquisition

Word formation in Arabic is rather different from English and relies more heavily on derivation rather than word creation. This study tests whether this difference may impact on the learning of words in English. Results of the study suggest that words that are irregularly derived in English are subject to a frequency effect in learning while regularly derived words are not. Results suggest that the predisposition of English for these irregular constructions may be a barrier to learning for learners with an aarabic speaking L1 background

The use of lexical complexity for assessing difficulty in instructional videos

Although measures of lexical complexity are well established for printed texts, there is currently no equivalent work for videos. This study, therefore, aims to investigate whether existing lexical complexity measures can be extended to predict second language (L2) learners’ judgment of video difficulty. Using a corpus of 320 instructional videos, regression models were developed for explaining and predicting difficulty using indices of lexical sophistication, density, and diversity. Results of the study confirm key dimensions of lexical complexity in estimates of video difficulty. In particular, lexical frequency indices accounted for the largest variance in the assessment of video difficulty (R2 = .45). We conclude with implications for CALL and suggest areas of further research

How many words do you need to speak Arabic? An Arabic vocabulary size test

This study describes a vocabulary size test in Arabic used with 339 nativespeaking learners at school and university in Saudi Arabia. Native speakervocabulary size scores should provide targets for attainment for learners ofArabic, should inform the writers of course books and teaching materials,and the test itself should allow learners to monitor their progress towardsthe goal of fluency. Educated native speakers of Arabic possess arecognition vocabulary about 25,000 words, a total which is largecompared with equivalent test scores of native speakers of English. Theresults also suggest that acquisition increases in speed with age and thisis tentatively explained by the highly regular system of morphologicalderivation which Arabic uses and which, it is thought, is acquired inadolescence. This again appears different from English where the rate ofacquisition appears to decline with age. While the test appears reliableand valid, there are issues surrounding the definition of a word in Arabicand further research into how words are stored, retrieved and processedin Arabic is needed to inform the construction of further tests whichmight, it is thought, profitably use a more encompassing definition ofthe lemma as the basis for testing

The Impact of Preschool Education on L1 Vocabulary Development and Sequential Bilingualism: The Case of Arab Schoolchildren

Considerable research has investigated the effect of preschool education on subsequent school success and proposed a positive link between the two. Less research, however, has directly investigated the influence of preschool education on children’s vocabulary development. This paper reports on a study that examines the impact of preschool education on children’s first language (L1) vocabulary development in early childhood settings and the potential impact this has on the successive acquisition of second language (L2) vocabulary in later school years. To conduct the study, data from 200 Arabic-English successive bilingual children were collected. The data are scores on receptive vocabulary knowledge in L1 and L2 of two groups of fourth grade schoolchildren (with and without preschool education). The results show that: (1) preschool education contributes largely to L1 vocabulary development and L2 vocabulary acquisition; (2) there is a strong link between L1 and L2 receptive vocabulary knowledge; and (3) bilingual mental lexicon size is predicted by preschool education. The present study provides further insights on the relation between preschool education and L1 vocabulary growth and the influence of this on sequential bilingualism. These findings will allow informed decisions on the support for preschool education by parents and educational policymakers

The impact of L1 lexical organisation in L2 vocabulary acquisition

Abstract This paper presents an empirical study investigating the relationship between first languag

Extensive Reading and Incidental Vocabulary Acquisition: The Case of a Predominant Language Classroom Input

A considerable body of research has investigated the effectiveness of extensive reading on incidental vocabulary acquisition in second language (L2) learners. However, we still know very little about the relationship between extensive reading and vocabulary development among Saudi learners of English as a foreign language (EFL) where language classroom is the predominant source of learning, if not the only one. In the present case study, a single participant was instructed to read extensively for eight weeks as an informal activity outside the classroom. The participant’s written receptive vocabulary knowledge was measured before and after the treatment. Results indicated that extensive reading contributed largely to the participant’s vocabulary gain, suggesting that a vocabulary uptake of about eight words from extensive reading intervention has occurred compared to about two words per contact hour from language classroom input where reading texts are short and scattered throught the textbook. Finding is interpreted in order to provide some pedagogical recommendations

Vocabulary knowledge and academic achievement revisited: General and academic vocabulary as determinant factors

It is uncontroversial to suggest that in order to be successful in academic study through the medium of English as a Foreign Lanuage, a learner will need a large general vocabulary and knowledge of academically relevant vocabulary, and the latter usually means knowledge of Coxhead’s influential Academic Word List (AWL). However, a large general vocabulary is likely to include all or most words from the AWL, so the contribution of knowledge of the AWL specifically to academic success is unclear. This article reports a study where the impact of word frequency in the test of the AWL is controlled, so the separate effects on grade point average (GPA) of AWL knowledge and general vocabulary size can be better understood. To this end, 61 native Arabic speaking learners of EFL took a test of AWL and a test of general vocabulary size, and their GPAs were collected. Results indicate that general vocabulary size explains nearly 47% of the variance in GPA and that knowledge of the AWL adds an additional 11.5 % to the explanation of the variance. The discussion addresses the varying importance of general and academic vocabulary to academic success

Measuring the contribution of specialist vocabulary knowledge to academic achievement: disentangling effects of multiple types of word knowledge

Abstract This study investigates the idea that knowledge of specialist subject vocabulary can make a significant and measurable impact on academic performance, separate from and additional to the impact of general and academic vocabulary knowledge. It tests the suggestion of Hyland and Tse (TESOL Quarterly, 41:235–253, 2007) that specialist vocabulary should be given more attention in teaching. Three types of vocabulary knowledge, general, academic and a specialist business vocabulary factors, are tested against GPA and a business module scores among students of business at a college in Egypt. The results show that while general vocabulary size has the greatest explanation of variance in the academic success factors, the other two factors - academic and a specialist business vocabulary - make separate and additional further contributions. The contribution to the explanation of variance made by specialist vocabulary knowledge is double that of academic vocabulary knowledge

Exploring Links Between Aural Lexical Knowledge and L2 Listening in Arabic and Japanese Speakers: A Close Replication of Cheng, Matthews, Lange and McLean (2022)

Aural lexical knowledge (ALK) is crucial for second language (L2) listening. Despite its importance, there is scant research that has validly explored the relationship between ALK and L2 listening across different English as a Foreign Language (EFL) contexts. In an effort to broaden this research base, the current study closely replicates a previous study, Cheng et al. (2022), which measured single-word ALK, phrasal verb ALK and L2 listening comprehension among participants with Chinese as a first language (L1). The current study administered the same instruments but did so among 147 Japanese and 131 Arabic-speaking English language learners. Results indicated that the capacity of ALK to predict variance in L2 listening for the Japanese group (R2 = .38) was similar to that observed in the original study (R2 = .42). However, the results for the Arabic-speaking group were very different to that of the original study and showed an unexpectedly strong relationship between ALK and L2 listening (R2 = .92). Future research directions and pedagogical implications are discussed
