Profiles of Second Language Learners in Bilingual Education: A Comparative Study of the Characteristics of Finnish and American Students

The purpose of this comparative study is to profile second language learners by exploring the factors which have an impact on their learning. The subjects come from two different countries: one group comes from Milwaukee, US, and the other from Turku, Finland. The subjects have attended bilingual classes from elementary school to senior high school in their respective countries. In the United States, the subjects (N = 57) started in one elementary school from where they moved on to two high schools in the district. The Finnish subjects (N = 39) attended the same school from elementary to high school. The longitudinal study was conducted during 1994-2004 and combines both qualitative and quantitative research methods. A Pilot Study carried out in 1990-1991 preceded the two subsequent studies that form the core material of this research. The theoretical part of the study focuses first on language policies in the United States and Finland: special emphasis is given to the history, development and current state of bilingual education, and the factors that have affected policy-making in the provision of language instruction. Current language learning theories and models form the theoretical foundation of the research, and underpin the empirical studies. Cognitively-labeled theories are at the forefront, but sociocultural theory and the ecological approach are also accounted for. The research methods consist of questionnaires, compositions and interviews. A combination of statistical methods as well as content analysis were used in the analysis. The attitude of the bilingual learners toward L1 and L2 was generally positive: the subjects enjoyed learning through two languages and were motivated to learn both. The knowledge of L1 and parental support, along with early literacy in L1, facilitated the learning of L2. This was particularly evident in the American subject group. The American subjects’ L2 learning was affected by the attitudes of the learners to the L1 culture and its speakers. Furthermore, the negative attitudes taken by L1 speakers toward L2 speakers and the lack of opportunities to engage in activities in the L1 culture affected the American subjects’ learning of L2, English. The research showed that many American L2 learners were isolated from the L1 culture and were even afraid to use English in everyday communication situations. In light of the research results, a politically neutral linguistic environment, which the Finnish subjects inhabited, was seen to be more favorable for learning. The Finnish subjects were learning L2, English, in a neutral zone where their own attitudes and motivation dictated their learning. The role of L2 as a means of international communication in Finland, as opposed to a means of exercising linguistic power, provided a neutral atmosphere for learning English. In both the American and Finnish groups, the learning of other languages was facilitated when the learner had a good foundation in their L1, and the learning of L1 and L2 were in balance. Learning was also fostered when the learners drew positive experiences from their surroundings and were provided with opportunities to engage in activities where L2 was used.

Näkökulmia kielen oppimisen käytäntöihin. Turun yliopiston kielikeskus 30 vuotta - Perspectives on Language Learning in Practice. University of Turku Language Centre 30-year Celebration

Tämä julkaisu ilmestyy Turussa 18.–19.5.2009 järjestettävien valtakunnallisten kielikeskuspäivien yhteydessä. Turun yliopiston kielikeskus viettää samaan aikaan 30-vuotisjuhlaansa. Erään luokittelun mukaan 30–45-vuotias elää varsinaista keski-ikäänsä, kun taas joissakin katsotaan, että 28–35 vuoden ikä on vasta ns. jäsentymisen vaihe ja että varhainenkin keski-ikä sijoittuu vasta ikävuosiin 35–42. Voitaneen siis sanoa, että kielikeskus on ainakin ohittanut nuoruusvuodet ja on jäsentymässä tai siirtymässä keski-ikään. Tämä tuo mukanaan tietynlaista kypsymistä, itsensä varaan asettumista, imagon ja profiilin vakiintumista. Tähän kasvuun saattaa liittyä myös jonkinlainen aikuistumisen kriisi. Sen myötä kuitenkin ymmärrys lisääntyy ja oman paikan rakentaminen yliopistoyhteisössä voimistuu. Arvo- ja ajatusmaailmaan tulee uusia kehityspiirteitä: olemassaolon ja toiminnan syvemmät perustelut, illuusioiden väheneminen, hallinnan tunne, tyydytys onnistuneesta toiminnasta ja realistinen voiman tunto. Laitos esittäytyy julkaisussa 13 kirjoituksen välityksellä. Tekstit ovat sisällöltään ja käsittelytavaltaan hyvin erilaisia, mutta juuri sellaisina ne valottavat monipuolisesti laitoksen ja sen henkilökunnan toimintaa ja tuntemuksia. Kuvaukset valaisevat laitoksen erikoisluonnetta ja kuvailevat henkilökunnan erilaisia tehtäviä. Kielikeskus paljastuu dynaamisemmaksi ja heterogeenisemmaksi yksiköksi kuin ensi silmäyksellä saattaa luulla, mutta juuri siinä piilee sen voima ja rikkaus. Juhlakirjaan toivottiin kirjoituksia kielikeskuksen opetukseen tai toimintaan liittyvistä aiheista. Kirjaan sisältyy selontekojen ja kuvausten lisäksi muutamia tiukan tieteellisiä artikkeleita. Joukossa on myös joitakin esseitä, jotka koskettelevat kielen ja kulttuurin välisiä suhteita ja luovat katsauksia kielikeskuksen monikulttuuriseen arkeen. Useassa kirjoituksessa käsitellään kielipedagogisia ja -didaktisia kysymyksiä. Erityisesti tulee esiin kielikeskuksessa viime vuosina tehty uudistustyö opetuksen ja oppimisedellytysten parantamiseksi. Samalla kun muun muassa opetusteknologiaa ja kielen oppimisen käytäntöjä virtuaalisissa oppimisympäristöissä on kehitetty, opettajan rooli on muovautunut uudentyyppiseksi: perinteisen opetushenkilöstön ja muun henkilökunnan tehtävät ja toimenkuva ovat selvästi lähentyneet toisiaan. Tämä suuntaus on jatkunut jo kauan ja jatkunee tulevaisuudessakin. Kolmekymmentä viime vuotta ovat olleet yliopistossa erittäin nopean muutoksen aikaa. Tämä on näkynyt erityisesti kielikeskuksen toiminnan laajenemisessa ja kehityksessä, joissa tosin on ollut notkahduksiakin. Varsinkin nopea kansainvälistyminen, Euroopan yhteisön laajentuminen ja koko maailman avautuminen ovat tuoneet mukanaan uusia haasteita, joihin kielikeskus on heti tarttunut: kielivalikoimaa on laajennettava, kielitaitoa kohennettava ja erilaisia kulttuureja tunnettava ja ymmärrettävä syvällisemmin. Turun yliopiston kielikeskus pyrkii omalta osaltaan täyttämään nämä velvoitteet ja luomaan toiminnallaan mahdollisimman hyvät edellytykset yliopiston kansainvälistymiselle. Nämä seikat on otettu huomioon laitoksen toimintalinjojen suunnittelussa ja kehittämisessä. Kieli-ja viestintäopintojen rakenteiden uudistamista jatketaan yhteistyössä tiedekuntien kanssa. Opintojen valinnaisuutta ja vapaaehtoisuutta pyritään lisäämään sekä turvaamaan kielivalintojen monipuolisuus ja kieliosaamisen laajaalaisuus resurssien mukaan. Toimintaa kehitetään niin, että siinä otetaan entistä paremmin huomioon yhteiskunnan monikulttuuristuminen ja Euroopan komission tavoite, jonka mukaan jokaisen EU- kansalaisen tulisi osata oman äidinkielensä lisäksi vähintään kahta yhteisön kieltä. Samalla otetaan huomioon globalisaation tuomat uudet haasteet tukemalla tärkeimpien Euroopan yhteisön ulkopuolisten kielten opetusta (mm. venäjä, kiina, japani, arabia). Edelleen kielikeskus seuraa tarkoin keskustelua Suomen kielikoulutuspolitiikan perusteista ja tavoitteista ja ottaa toimintansa suunnittelussa huomioon valtakunnalliset suositukset Suomen kielikoulutuksen uudistamiseksi vastaamaan nykypäivän ja tulevaisuuden tarpeita ja tavoitteita. Se että kielikeskus on viime vuosina selvästikin vakiinnuttanut asemansa yliopiston strategisesti tärkeänä yksikkönä, ei tarkoita sitä, että nyt voitaisiin turvautua pelkästään vanhoihin toimintamalleihin ja rutiineihin. Päinvastoin, koko maailmassa, suomalaisessa yhteiskunnassa ja yliopistojen toiminnassa tapahtuneet ja tapahtuvat suuret muutokset edellyttävät kielikeskustoimintojen vireää kehittämistä ja uudistusmieltä. Laitos onkin ilmoittanut tulossopimuksessaan tukevansa opetuskokeiluja ja innovatiivisia ratkaisuja. Opettajajohtoisen opetuksen ohella on voimakkaasti kehitetty myös ohjattua itseopiskelua, monimuotoopetusta sekä vaihtoehtoisia ja uudentyyppisiä oppimismuotoja. Uutta opetusteknologiaa käytetään tehokkaasti hyväksi ja kehitetään edelleen. Opetuksessa ja ohjauksessa käytetään suomalaisten ja ulkomaisten opiskelijoiden työpanosta. Laitoksen suunnittelu- ja kehittämistyössä opiskelijat ovat toimineet viime vuosina aktiivisesti ja ansiokkaasti: yhteistyö ylioppilaskunnan kanssa toimii erinomaisesti, ja sitä on tarkoitus vielä tehostaa. Laitos on saanut runsaasti kiitosta korkealaatuisesta toiminnastaan: muun muassa v. 1998 ja 2008 Turun yliopiston vuoden opettajan palkinnon, v. 1999 Turun yliopiston parhaan koulutusyksikön palkinnon ja v. 2007 vuoden opintojaksopalkinnon. On toivottavaa, että tämä tuloksellinen työ jatkuisi ja entisestäänkin paranisi tulevina vuosina. Hyvät tulokset on saavutettu kovilla ponnistuksilla ja tiukalla sitoutumisella työhön. Aina se ei ole ollut aivan helppoa nopeiden muutosten myllerryksessä, tiukentuneessa resurssitilanteessa ja vaatimusten ja odotusten ristiriidoissa. Toivon, että pääosin hyvin sujunut yhteistyö yliopiston johdon, tiedekuntien ja opiskelijoiden kanssa sekä henkilökunnan keskuudessa voisi säilyä ja kehittyä ja että alkava vuosikymmen kielikeskuksen historiassa voisi olla entistä parempi. Hyvä yhteistyö on hyvien tulosten edellytys. Suurten uudistusten vuosi 2010 sisältää mahdollisuuden parempaan, mutta se on samalla myös riski ehkä hyvinkin paljon muuttuvassa toimintaympäristössä. Lainaan lopuksi roomalaisen historioitsijan Sallustiuksen sanat: Concordia res parvae crescunt, discordia maximae dilabuntur. Yksimielisyys saa pienetkin asiat kukoistamaan, eripura suuretkin tuhoaa. Turun yliopistolla on hyvä kielikeskus, jota kannattaa vaalia ja tukea. Kiitän kaikkia kirjoittajia ja juhlajulkaisun toimittajia Minna Maijalaa, Timo Hulkkoa ja Jane Honkaa tämän julkaisun synnystä. Samoin esitän kiitokset kielikeskuksen kirjallisen viestinnän lehtoreille, Markus Lahdelle ja Arja Lampiselle, jot ka ovat nähneet vaivaa tekstien kielellisinä korjaajina. Koko kielikeskuksen nykyistä ja aikaisempaa henkilökuntaa kiitän työstä, jota laitoksen hyväksi on tehty kuluneiden 30 vuoden aikana. Erityisen kiitoksen ansaitsee laitoksen juhlatoimikunta kaikista juhlavuoden järjestelyistä.

Is there a relationship between bilingual language switching and executive functions in bilingualism? Introducing a within-group analysis approach

Several studies have suggested a bilingual advantage in executive functions, presumably due to bilinguals' massive practice with language switching that requires executive resources, but the results are still somewhat controversial. Previous studies are also plagued by the inherent limitations of a natural groups design where the participant groups are bound to differ in many ways in addition to the variable used to classify them. In an attempt to introduce a complementary analysis approach, we employed multiple regression to study whether the performance of 30- to 75-year-old FinnishSwedish bilinguals (N = 38) on tasks measuring different executive functions (inhibition, updating, and set shifting) could be predicted by the frequency of language switches in everyday life (as measured by a language switching questionnaire), L2 age of acquisition, or by the self-estimated degree of use of both languages in everyday life. Most consistent effects were found for the set shifting task where a higher rate of everyday language switches was related to a smaller mixing cost in errors. Mixing cost is thought to reflect top-down management of competing task sets, thus resembling the bilingual situation where decisions of which language to use has to be made in each conversation. These findings provide additional support to the idea that some executive functions in bilinguals are affected by a lifelong experience in language switching and, perhaps even more importantly, suggest a complementary approach to the study of this issue.

Self-assessment of individual differences in language switching

Language switching is omnipresent in bilingual individuals. In fact, the ability to switch languages (code switching) is a very fast, efficient, and flexible process that seems to be a fundamental aspect of bilingual language processing. In this study, we aimed to characterize psychometrically self-perceived individual differences in language switching and to create a reliable measure of this behavioral pattern by introducing a bilingual switching questionnaire. As a working hypothesis based on the previous literature about code switching, we decomposed language switching into four constructs: (i) L1 switching tendencies (the tendency to switch to L1; L1-switch); (ii) L2 switching tendencies (L2-switch); (iii) contextual switch, which indexes the frequency of switches usually triggered by a particular situation, topic, or environment; and (iv) unintended switch, which measures the lack of intention and awareness of the language switches. A total of 582 SpanishCatalan bilingual university students were studied. Twelve items were selected (three for each construct). The correlation matrix was factor-analyzed using minimum rank factor analysis followed by oblique direct oblimin rotation. The overall proportion of common variance explained by the four extracted factors was 0.86. Finally, to assess the external validity of the individual differences scored with the new questionnaire, we evaluated the correlations between these measures and several psychometric (language proficiency) and behavioral measures related to cognitive and attentional control. The present study highlights the importance of evaluating individual differences in language switching using self-assessment instruments when studying the interface between cognitive control and bilingualism.

Sexual dimorphism of sonic apparatus and extreme intersexual variation of sounds in Ophidion rochei (Ophidiidae): first evidence of a tight relationship between morphology and sound characteristics in Ophidiidae

Many Ophidiidae are active in dark environments and display complex sonic apparatus morphologies. However, sound recordings are scarce and little is known about acoustic communication in this family. This paper focuses on Ophidion rochei which is known to display an important sexual dimorphism in swimbladder and anterior skeleton. The aims of this study were to compare the sound producing morphology, and the resulting sounds in juveniles, females and males of O. rochei.Results: Males, females, and juveniles possessed different morphotypes. Females and juveniles contrasted with males because they possessed dramatic differences in morphology of their sonic muscles, swimbladder, supraoccipital crest, and first vertebrae and associated ribs. Further, they lacked the ‘rocker bone’ typically found in males. Sounds from each morphotype were highly divergent. Males generally produced non harmonic, multiple-pulsed sounds that lasted for several seconds (3.5 ± 1.3 s) with a pulse period of ca. 100 ms. Juvenile and female sounds were recorded for the first time in ophidiids. Female sounds were harmonic, had shorter pulse period (±3.7 ms), and never exceeded a few dozen milliseconds (18 ± 11 ms). Moreover, unlike male sounds, female sounds did not have alternating long and short pulse periods. Juvenile sounds were weaker but appear to be similar to female sounds.Conclusions: Although it is not possible to distinguish externally male from female in O. rochei, they show a sonic apparatus and sounds that are dramatically different. This difference is likely due to their nocturnal habits that may have favored the evolution of internal secondary sexual characters that help to distinguish males from females and that could facilitate mate choice by females. Moreover, the comparison of different morphotypes in this study shows that these morphological differences result from a peramorphosis that takes place during the development of the gonads

First- and second-language phonological representations in the mental lexicon

Performance-based studies on the psychological nature of linguistic competence can conceal significant differences in the brain processes that underlie native versus nonnative knowledge of language. Here we report results from the brain activity of very proficient early bilinguals making a lexical decision task that illustrates this point. Two groups of SpanishCatalan early bilinguals (Spanish-dominant and Catalan-dominant) were asked to decide whether a given form was a Catalan word or not. The nonwords were based on real words, with one vowel changed. In the experimental stimuli, the vowel change involved a Catalan-specific contrast that previous research had shown to be difficult for Spanish natives to perceive. In the control stimuli, the vowel switch involved contrasts common to Spanish and Catalan. The results indicated that the groups of bilinguals did not differ in their behavioral and event-related brain potential measurements for the control stimuli; both groups made very few errors and showed a larger N400 component for control nonwords than for control words. However, significant differences were observed for the experimental stimuli across groups: Specifically, Spanish-dominant bilinguals showed great difficulty in rejecting experimental nonwords. Indeed, these participants not only showed very high error rates for these stimuli, but also did not show an error-related negativity effect in their erroneous nonword decisions. However, both groups of bilinguals showed a larger correctrelated negativity when making correct decisions about the experimental nonwords. The results suggest that although some aspects of a second language system may show a remarkable lack of plasticity (like the acquisition of some foreign contrasts), first-language representations seem to be more dynamic in their capacity of adapting and incorporating new information. &

Population structure in a highly pelagic seabird, the Cory's shearwater (Calonectris diomedea): an examination of genetics, morphology and ecology

Increasing evidence suggests oceanic traits may play a key role in the genetic structuring of marine organisms. Whereas genetic breaks in the open ocean are well known in fishes and marine invertebrates, the importance of marine habitat characteristics in seabirds remains less certain. We investigated the role of oceanic transitions versus population genetic processes in driving population differentiation in a highly vagile seabird, the Cory"s shearwater, combining molecular, morphological and ecological data from 27 breeding colonies distributed across the Mediterranean (Calonectris diomedea diomedea) and the Atlantic (C. d. borealis). Genetic and biometric analyses showed a clear differentiation between Atlantic and Mediterranean Cory"s shearwaters. Ringing-recovery data indicated high site fidelity of the species, but we found some cases of dispersal among neighbouring breeding sites (<300 km) and a few long distance movements (>1000 km) within and between each basin. In agreement with this, comparison of phenotypic and genetic data revealed both current and historical dispersal events. Within each region, we did not detect any genetic substructure among archipelagos in the Atlantic, but we found a slight genetic differentiation between western and eastern breeding colonies in the Mediterranean. Accordingly, gene flow estimates suggested substantial dispersal among colonies within basins. Overall, genetic structure of the Cory"s shearwater matches main oceanographic breaks (Almería-Oran Oceanic Front and Siculo-Tunisian Strait), but spatial analyses suggest that patterns of genetic differentiation are better explained by geographic rather than oceanographic distances. In line with previous studies, genetic, phenotypic and ecological evidence supported the separation of Atlantic and Mediterranean forms, suggesting the 2 taxa should be regarded as different species.

A Case-based reasoning approach to validate grammatical gender and number agreement in Spanish language

Across Latin America 420 indigenous languages are spoken. Spanish is considered a second language in indigenous communities and is progressively introduced in education. However, most of the tools to support teaching processes of a second language have been developed for the most common languages such as English, French, German, Italian, etc. As a result, only a small amount of learning objects and authoring tools have been developed for indigenous people considering the specific needs of their population. This paper introduces Multilingual–Tiny as a web authoring tool to support the virtual experience of indigenous students and teachers when they are creating learning objects in indigenous languages or in Spanish language, in particular, when they have to deal with the grammatical structures of Spanish. Multilingual–Tiny has a module based on the Case-based Reasoning technique to provide recommendations in real time when teachers and students write texts in Spanish. An experiment was performed in order to compare some local similarity functions to retrieve cases from the case library taking into account the grammatical structures. As a result we found the similarity function with the best performance

The Connectivity of Musical Aptitude and Foreign Language Learning Skills: Neural and Behavioural Evidence

Given the structural and acoustical similarities between speech and music, and possible overlapping cerebral structures in speech and music processing, a possible relationship between musical aptitude and linguistic abilities, especially in terms of second language pronunciation skills, was investigated. Moreover, the laterality effect of the mother tongue was examined with both adults and children by means of dichotic listening scores. Finally, two event-related potential studies sought to reveal whether children with advanced second language pronunciation skills and higher general musical aptitude differed from children with less-advanced pronunciation skills and less musical aptitude in accuracy when preattentively processing mistuned triads and music / speech sound durations. The results showed a significant relationship between musical aptitude, English language pronunciation skills, chord discrimination ability, and sound-change-evoked brain activation in response to musical stimuli (durational differences and triad contrasts). Regular music practice may also have a modulatory effect on the brain’s linguistic organization and cause altered hemispheric functioning in those who have regularly practised music for years. Based on the present results, it is proposed that language skills, both in production and discrimination, are interconnected with perceptual musical skills.

La productividad de la morfología verbal a los años dos años de edad

Este trabajo se centra en estudiar la adquisición de la morfología verbal en una lengua con un paradigma verbal morfológicamente rico. Se predice que los niños de dos años no mostrarán productividad morfológica ante verbos desconocidos. La muestra se compone de 12 sujetos de edades comprendidas entre los 22 y los 31 meses. El procedimiento, de tipo experimental, se caracteriza por entrenar a los niños con verbos inventados. Los resultados muestran que los sujetos solamente utilizan los nuevos verbos con la forma morfológica con la que se han presentado. También se observa la omisión de determinados constituyentes de la oración. Estos resultados se discuten en relación con la asunción de discontinuidad de las competencias lingüísticas infantiles

La relación entre el aprendizaje léxico y el desarrollo gramatical

El presente trabajo se centra en estudiar la relación que existe entre el desarrollo de léxico y el de la morfosintaxis. Concretamente pretendemos explorar el tipo de vocabulario que mejor predice el desarrollo de la morfología verbal y el de la complejidad gramatical, así como establecer el tipo de relación entre desarrollo léxico y desarrollo morfosintáctico. La muestra comprende 517 niños de edades comprendidas entre los 18 meses y los 30 meses. Los datos se han recogido a partir de la adaptación al catalán del instrumento MacArthur-Bates Communicative Development Inventories (CDI). Los resultados muestran que el mejor predictor del desarrollo morfológico y gramatical es el vocabulario de clase cerrada, conjuntamente con el vocabulario general. Por otra parte, se observa una relación predominantemente lineal entre el desarrollo del léxico y el desarrollo morfosintáctico

The usefulness of phonological information for the acquisition of grammatical structure in child language development

During the process of language development, one of the most important tasks that children must face is that of identifying the grammatical category to which words in their language belong. This is essential in order to be able to form grammatically correct utterances. How do children proceed in order to classify words in their language and assign them to their corresponding grammatical category? The present study investigates the usefulness of phonological information for the categorization of nouns in English, given the fact that it is phonology the first source of information that might be available to prelinguistic infants who lack access to semantic information or complex morphosyntactic information. We analyse four different corpora containing linguistic samples of English speaking mothers addressing their children in order to explore the reliability with which words are represented in mothers’ speech based on several phonological criteria. The results of the analysis confirm the prediction that most of the words to which English learning infants are exposed during the first two years of life can be accounted for in terms of their phonological resemblance

El plan de lengua y cohesión social en Catañunya: primeros datos de una investigación = Language and Social Cohesion Plan in Catalonia: Initial research data

Los programas de inmersión lingüística han constituido y constituyen dentro del Sistema Educativo catalánla principal forma para que el alumnado de lengua familiar no-catalana aprenda una nueva lengua, el catalán,sin que, en su proceso de aprendizaje, vea mermado ni el desarrollo de su propia lengua ni su rendimientoacadémico. El éxito de la inmersión lingüística en las décadas anteriores ha sido frecuentemente utilizado comouno de los argumentos orientativos para justificar la política lingüística que se sigue en la escolarización de lainfancia extranjera. Sin embargo, los resultados obtenidos por investigaciones recientes parece que no avalanempíricamente dicho argumento. Este artículo analiza dichos resultados y expone, a partir del Plan para laLengua y Cohesión Social puesto en marcha por el Departamento de Educación de la Generalitat de Cataluña,cuáles son los retos que se presentan a su Sistema Educativo dentro del nuevo marco que supone el aumento de ladiversidad cultural y lingüística en la actual sociedad catalana
