The main objective of this thesis is to establish whether or not there is a relationship between (foreign) language aptitude, pronunciation learning strategies (PLSs), and pronunciation performance. Also, embedded in the major objective is the aim of uncovering which PLSs are most frequently used and which PLSs have been used for the longest period of time. Following a positivistic approach to research, through a correlational and statistically descriptive methodology, all participants were asked to take three tests, each of which was intended to gather data for the three major variables under consideration, namely an adapted version of the Strategic Pronunciation Learning Survey (SPLS), the first two sections of the Modern Language Aptitude Test (MLAT), and a Pronunciation Test (PT), developed by the researcher. The study was conducted at a teacher education university in Chile, with a sample of 43 students, 24 of whom were Year 2 students and 19 were Year 3 students at the time of data collection. The results suggest that there is a good deal of coincidence between those PLSs that are used with the highest frequency and those used with the greatest duration. The results also indicate that the PLSs that are more frequently used and that have been used for the longest period of time by the participants seem to be of a cognitive type, following Oxford’s (1990) broad classification of learning strategies. Finally, the Spearman correlation tests and the diverse statistical models applied reveal that no major correlations were found between PLS frequency/duration and pronunciation accuracy; nor was a major correlation found between language aptitude and pronunciation accuracy. Nonetheless, the application of a statistical model comprising the most frequently used PLSs and those with the longest duration yielded a positive correlation between these PLSs and pronunciation intelligibility levels. Future studies incorporating motivational elements are required to establish how they correlate with pronunciation accuracy in particular. Similarly, research seeking to establish correlations between (a new version of) PLSs, grouped into factors through factor analysis, and pronunciation accuracy is recommended. Lastly, language aptitude – viewed, conceptualised, and quite possibly measured differently, considering differentiating elements (Robinson, 2007; Winke, 2013), is to be further examined to establish whether it can explain pronunciation accuracy in a larger sample of participants.

The purpose of this study was to determine whether language aptitude and the use of language strategies predict pronunciation gains in second language (L2) acquisition. A second goal was to determine whether these factors differed depending on whether learning occurred in an English as a second language (ESL) or English as a foreign language (EFL) learning context. Eighty-six ESL students in the United States and one hundred EFL students in China were asked to take the Pimsleur language aptitude test. The top 15 or 16 and lowest 15 or 16 scorers on this test from each group were asked to complete a test of pronunciation proficiency and a pronunciation strategies inventory at the beginning and end of a 10-week speaking class in which they were enrolled. The pre and post pronunciation tests were rated and pronunciation proficiency gains in global foreign accent, fluency, comprehensibility and accuracy were compared to both Pimsleur test scores and use of pronunciation strategies before and after training. Results indicated that general language aptitude did not predict pronunciation gains regardless of type of setting (ESL or EFL), but that auditory aptitude may be linked to pronunciation proficiency. Analyses revealed that specific pronunciation strategies were strong predictors of pronunciation gain for comprehensibility and accuracy gains. The findings for this study suggest that pronunciation strategies seem to play a bigger role in pronunciation improvement than language aptitude and are effective in both ESL and EFL settings.

The proposed thesis treats the topic of multilingual language acquisition and the occurring language interference. It aims to demonstrate the negative language transfer by the means of the results of a field research. The theoretical part introduces and discusses relevant topics, such as language learning, language processing, bilingualism and multilingualism. Furthermore, it focuses on the character of language transfer itself. In the practical part, two hypotheses are presented, specifically "the interference of the dominant foreign language is considerably higher than the interference of the other language, i.e. L3" and "passive interference reaches a higher degree than the active one". Eventually, the results interpretation is presented and both the hypotheses are verified.

The present dissertation is concerned with language aptitude in young learners. The first aim of this dissertation is to validate the content of two new instruments: the adaptation to both Spanish (MLAT-ES) and Catalan (MLAT-EC) of the Modern Language Aptitude Test – Elementary (MLAT-E) (Carroll & Sapon, 1967). The second aim of this dissertation is to study the relationship between language aptitude, L1 acquisition and cognitive development. The norming study of the MLAT-E offers data of children from grade 3 to 6 while that of the MLAT-ES covers grades 3 to 7. In both norming studies, while means increase steadily from grades 4 to 6, the largest increase is observed between grade 3 and 4. The third aim of this dissertation is related to the variable sex. While in the MLAT-E study the data appear divided according to this variable, the population in the MLAT-ES norming study appears as one cohort. It would be interesting to see if significant differences are observed between the performance of boys and girls to keep this variable or not when using these tests. Finally, the fourth aim of this study is to check the construct validity of the tests. The MLAT-E tests are intended to measure language aptitude for foreign language learning. One way to check their construct validity is to correlate scores on the tests with measures of foreign language proficiency. The first aim of the study - the validation of two versions of the MLAT-E in Spanish and Catalan - is supported by the statistical results obtained although some of the items in the MLAT-ES do not work as expected (or as they do for monolingual Spanish speakers or speakers of a Spanish regional variety other than the Peninsular). As for the second aim, it was observed that the tests functioned in a different way for 3-graders than for the rest of grades, as in the previous norming studies. This could be explained by the fact that 3-graders are at the beginning of their concrete operational stage, which limits their cognitive processing abilities. From an information processing perspective, children at this stage still have to develop problem-solving strategies as well as strategies for encoding and memorising information. Moreover, they have become literate relatively recently and show to have lower meta-linguistic awareness than their older counterparts. The third aim dealt with the sex variable. The results show that aptitude does not seem to be affected by the participants’ sex. However, perhaps a more cognitive oriented approach into the way each of the parts of the MLAT-E is answered would shed light on sex differences, if any. These should be explored along with different proficiency measures, those that, traditionally, have given an advantage to girls over boys (such as fluency) and vice versa (e.g. receptive tasks). Regarding the construct validity of the tests, both the MLAT-ES and the MLATEC seem to be valid measures of predictability of general concurrent proficiency although not in all skills, since the speaking skill sometimes did not correlate with the aptitude measures. Also, correlations in grade 3 were consistently non-existent or lower than those in other grades. This phenomenon could be related to the issues discussed in relation to the participants’ age and cognitive development and/or to the validity of the proficiency measures used. Consequently, the MLAT-ES and the MLATEC should be revised if they are to be administered to children this age. Oral data were collected from most participants, so perhaps a deep analysis of these oral data will shed more light on the relationship between FL aptitude in young learners and their true FL proficiency in further research. / Aquesta tesi doctoral presenta la validació de dos tests d’aptitud per a l’aprenentatge de llengües estrangeres en un context bilingüe català/castellà. Es tracta de l’adaptació al castellan (MLAT-ES) i al català (MLAT-EC) del Modern Language Aptitude Test – Elementary (MLAT-E) (Carroll i Sapon, 1967). 629 estudiants d’edats compreses entre els 8 i els 13 anys (de 3r de primària a 1r d’ESO) participaren en aquest estudi. Un cop validat el contingut d’ambdós tests, la primera pregunta de recerca explora la relació entre l’aptitud, l’adquisició de la L1 i el desenvolupament cognitiu, ja que els resultats mostren que, si bé les mitjanes obtingudes en els tests augmenten amb l’edat, aquest augment és molt més gran entre 3r i 4t de primària que entre els altres cursos. Aquesta diferència es podria explicar per l’estat de desenvolupament cognitiu dels participants a 3r de primària així com pel fet que en aquesta edat algunes estratègies de resolució de problemes i de memorització, entre altres, encara estan en vies de desenvolupament. La segona pregunta d’investigació té a veure amb la variable sexe. No s’observen diferències significatives entre els resultats obtinguts pels nens i nenes participants. Finalment, l’objectiu de la tercera pregunta de recerca és comprovar la validesa de constructe del MLAT-ES i del MLAT-EC correlacionant els resultats obtinguts amb proves de proficiència en llengua estrangera (anglès). Ambdós tests semblen ser vàlids en aquest aspecte tot i que amb excepcions significatives al grup de 3r de primària, sobretot pel que fa a la proficiència oral. Aquestes diferències es podrien explicar per les proves de proficiència utilitzades o per l’estat de desenvolupament cognitiu d’aquests participants, que podria haver influït en la manera com interpretaven els tests d’aptitud. Per tant, en futurs estudis s’hauria d’explorar amb més detall si les habilitats mesurades pels tests d’aptitud en nens i nenes d’entre 8 i 9 anys són les mateixes que en estudiants més grans.

The purpose of this study was to investigate the effects of metalinguistic knowledge and language learning aptitude on second language (L2) procedural knowledge. Three lines of inquiry were undertaken: (a) confirming the factorial structure of metalinguistic knowledge and language learning aptitude; (b) testing the relative effects of metalinguistic knowledge and language learning aptitude on L2 procedural knowledge; and (c) assessing the relative contributions of receptive and productive metalinguistic knowledge and components of language learning aptitude to L2 procedural knowledge. Two-hundred-forty-nine Japanese university students participated. One receptive and two productive tests of metalinguistic knowledge related to metalinguistic terminology and English grammatical rules were administered. Learners' language learning aptitude was measured using the Lunic Language Marathon, which consisted of four scales: number learning, sound-symbol association, vocabulary learning, and language analytical ability. Participants' L2 procedural knowledge was assessed through performance on a timed writing task. The writing samples were scored for overall quality, L2 complexity, accuracy, and fluency. The scores from each test were subjected to Rasch analyses to investigate the construct validity and unidimensionality of the instruments. The results of the Rasch analyses indicated that the test items fit the Rasch model, supporting the construct validity of the instruments. The unidimensionality of each instrument was established through Rasch principal component analyses. Interval-level Rasch measures were used for the subsequent analyses. The results of exploratory and confirmatory factor analyses indicated that metalinguistic knowledge and language learning aptitude were distinct constructs. A two-factor model showed good model fit and explained the relationship between the two constructs. Structural equation modeling revealed that metalinguistic knowledge significantly predicted L2 procedural knowledge, complexity, accuracy, and fluency. Language learning aptitude, however, was not a statistically significant predictor of the L2 procedural knowledge variables. The results of a path model analysis indicated that productive metalinguistic knowledge was the strongest predictor of L2 procedural knowledge, language analytical ability predicted receptive metalinguistic knowledge, and number learning was negatively associated with L2 procedural knowledge. The findings point to the facilitative role of metalinguistic knowledge in L2 learning and the viability of L2 declarative knowledge becoming proceduralized through practice. / Applied Linguistics

The senior secondary school learners' limited English proficiency motivated the researcher to investigate the extent to which contextual and learner factors contributed to this problem. The ultimate aim was to recommend guidelines for dealing with the problem. The review of literature and empirical methods of research were used to this effect. The literature review revealed that the learners' societal, home/family and school/classroom contexts contributed to learners' development ofESL proficiency. It further showed that the independent learner factors (i.e. learner factors that are not influenced by the context from which the learner comes and/or in which SLA takes place) and dependent learner factors (i.e. learner factors that are completely or partly subject to the influence of the context from which the learner comes or in which SLA takes place) significantly influenced the development ofESL proficiency. With its focus on language learning strategies, the empirical investigation found a significant relationship between the learners' level ofESL proficiency and use of direct strategies (i.e. strategies that involve the mental processing of the target language, albeit in different ways and for different purposes). The investigation found no significant relationship between the learners' level of ESL proficiency and use of indirect strategies (i.e. strategies that underpin the process of language learning). Several contextual and learner factors were found to influence the relationship between the learner's strategy use and the development ofESL proficiency. These findings formed the basis for recommending specific guidelines for dealing with limited ESL proficiency, as well as recommending possible directions for future research. / Educational Studies / D.

L’enseignement des langues par la tâche est une approche d’enseignement des langues secondes de plus en plus adoptée dans différents contextes. Toutefois, la place de l’enseignement de la forme au sein d’une tâche fait toujours l’objet d’un débat. En plus de savoir si l’enseignement de la forme devrait se faire de façon préventive ou réactive (Ellis, 2017; Long, 2015), le moment auquel il faudrait procéder à un enseignement de la forme ne fait pas consensus, que ce soit au début de la tâche (Dekeyser, 1997, 2007), pendant la tâche (Lightbown, 2008; Long, 2015) ou après la tâche (Willis et Willis, 2007). Cette incertitude mène les enseignants à se demander s’ils devraient intégrer ou non un enseignement de la forme à une tâche et à quel moment ils devraient le faire (East, 2017). La présente étude quasi expérimentale vise à mieux comprendre le rôle lié au moment de procéder à un enseignement de la forme dans le cadre d’une tâche et à contrôler certaines variables qui peuvent moduler les effets du type d’enseignement, dont le niveau de connaissances initiales et l’aptitude langagière des apprenants. Huit groupes, six groupes expérimentaux et deux groupes témoins, d’étudiants de français langue seconde (quatre groupes de niveau B1 et quatre groupes de niveau B2) ainsi que leurs enseignants respectifs ont participé à l’étude. L’intervention expérimentale consistait en une tâche de hiérarchisation et une tâche de prise de décision. Six groupes ont reçu un enseignement explicite du subjonctif soit au début de chaque tâche, soit pendant la tâche, soit après la tâche et deux groupes ont réalisé les deux tâches sans recevoir d’enseignement explicite. Les participants (n = 165) ont effectué un prétest, un post-test immédiat et un post-test différé mesurant les connaissances implicites (test d’imitation sollicitée) et explicites (test de jugement de la grammaticalité) et ont effectué un test mesurant l’aptitude langagière (LLAMA). Le degré de connaissances des apprenants a été déterminé en fonction de leurs résultats aux prétests. Les participants dont les résultats étaient en dessous de la médiane ont été attribués aux groupes de niveau faible et ceux dont les résultats étaient au-dessus de la médiane ont été attribués aux groupes de niveau avancé. Les résultats d’ANOVA à mesures répétées montrent que les apprenants moins avancés semblent bénéficier d’un enseignement pendant la tâche, alors que les étudiants plus avancés semblent bénéficier d’un enseignement au début de la tâche. Par conséquent, le niveau des apprenants est à prendre en considération au moment de planifier un enseignement de la forme. Par ailleurs, les résultats de régressions multiples montrent que l’aptitude langagière est davantage sollicitée dans les conditions d’enseignement de la forme avant ou pendant la tâche et que différentes composantes interviennent à des stades d’acquisition différents. Cette étude offre des répercussions pratiques et théoriques au regard du moment de procéder à un enseignement de la forme en fonction du niveau des apprenants et de leur aptitude langagière. / Task-Based Language Teaching is an increasingly popular approach used in a variety of second-language learning environments. There is debate, however, on the incorporation of form-focused instruction and, more specifically, regarding when precisely it should be integrated in the execution of a task. Beyond determining whether a form should be taught proactively or reactively (Ellis, 2017, Long, 2015), the lack of consensus as to whether form-focused instruction should occur at the beginning of a task (Dekeyser, 1997, 2007), during a task (Lightbown, 2008; Long, 2015), or after a task (Willis et Willis, 2007) drives language instructors to question whether they should integrate form-focused instruction at all and creates uncertainty as to when it is most beneficial to do so (East, 2017). The present quasi experimental study seeks to better understand the effects of the timing of form-focused instruction in the task-based teaching framework while controlling for moderating variables such as the degree of learner knowledge and learners’ language aptitude. Eight groups, six experimental and two comparison, of French as a second language students (four groups of B1 level and four groups of B2 level) and their respective teachers participated in the study. The experimental intervention consisted of two tasks, one hierarchical task and one decision-making task. Six groups received explicit instruction on the subjunctive at the beginning, during, or after a task while two groups completed the tasks without explicit instruction. The participants (N = 165) completed a pre-test, an immediate post-test and a delayed post-test assessing both implicit knowledge (Elicited Imitation Test) and explicit knowledge (Grammaticality Judgment Test). Participants also completed a language aptitude assessment test (LLAMA). Learners’ degree of knowledge was determined based on their pre-test performance. Participants whose mean scores were below or above the median were assigned to the low or advanced knowledge groups respectively. Repeated-measures ANOVAs show that lower-level learners benefit from instruction during a task while more advanced learners benefit from instruction at the start of a task. Consequently, learner readiness is a factor to consider when planning and executing focus on form instruction. Additionally, multiple regression results demonstrate that language aptitude plays a more significant role when form-focused instruction is given before or during a task and that different components are drawn upon at different acquisitional stages. The study concludes by offering theories and practical recommendations regarding the inclusion of focus on form instruction that considers the level and aptitude of learners.
