Cross-situational learning of object-word mapping using Neural Modeling Fields

The issue of how children learn the meaning of words is fundamental to developmental psychology. The recent attempts to develop or evolve efficient communication protocols among interacting robots or Virtual agents have brought that issue to a central place in more applied research fields, such as computational linguistics and neural networks, as well. An attractive approach to learning an object-word mapping is the so-called cross-situational learning. This learning scenario is based on the intuitive notion that a learner can determine the meaning of a word by finding something in common across all observed uses of that word. Here we show how the deterministic Neural Modeling Fields (NMF) categorization mechanism can be used by the learner as an efficient algorithm to infer the correct object-word mapping. To achieve that we first reduce the original on-line learning problem to a batch learning problem where the inputs to the NMF mechanism are all possible object-word associations that Could be inferred from the cross-situational learning scenario. Since many of those associations are incorrect, they are considered as clutter or noise and discarded automatically by a clutter detector model included in our NMF implementation. With these two key ingredients - batch learning and clutter detection - the NMF mechanism was capable to infer perfectly the correct object-word mapping. (C) 2009 Elsevier Ltd. All rights reserved.

Podcasting Oral Presentations

This presentation tells how podcasts can be used to enhance the learning experience of English as a Second Language (ESL) students registered in a content-based language immersion program. The students were placed in groups of four and asked to prepare an oral presentation. The topics of the presentations included Financial Aid, College Courses and Course Schedules and Academic Policies. Each presentation was podcasted to give students an opportunity for self-evaluation and feedback.

"She was a Bitch" : A Socio-Educational Perspective on Motivation for Learning English.

AbstractThis degree project focuses motivation for learning English among a group of Swedish uppersecondary school students. By employing a socio-educational perspective, some vital factorsbehind a strong motivation for learning English in school are investigated through individualinterviews. Components in the past, heralding either a high level of motivation for English or a low such, are primarily focused. Moreover, essential socio-educational factors behind managing to achieve grades in English despite a low level of motivation and various impediments, such as severe socio-psychological adversities, are looked into. While motivation for English is emphasized as a critical factor, in accordance with socio-educational motivation theory, the study also stresses the importance of a positive first encounter with the English language, a satisfying English teacher-student relationship, and a sense of success in the English classroom. But above all, the study stresses a need for early tests among young students for reading disabilities, which according to this study often go undetected and thus severely impede any kind of second language learning and motivation.

Un estudio sociolingüístico sobre el catalán : Los efectos de la inmersión lingüística

This thesis analyzes the current state of the language immersion program in Catalonia after its implementation 30 years ago, and after the immigration wave of the last decade. The language immersion is a method of teaching a second language using a language of instruction different than the students’ mother tongue. The Catalan authorities use this as a method for preserving Catalan in the society.The aim of this study is to examine the use of Catalan at school and outside of school by students who have followed the language immersion program. Language attitudes play an important role for the maintenance of a minority language, as Catalan. Therefore, in this study, the informants’ attitudes towards Catalan have also been measured. The method applied is a quantitative method where the informants have answered a written questionnaire. The results show a high level of knowledge of Catalan and its frequent use in the classroom. In contrast, outside of school the Castilian language is more often used. The informants seem to have a positive attitude towards Catalan.The conclusion is that the language immersion works satisfactory in a school context but often fails outside of school.

”Vi måste träna på språket hela tiden precis som man måste göra om man vill bli duktig på fotboll” : Pedagogers syn på att arbeta med elever som har svenska som andraspråk

Syftet med denna studie är att få en inblick i hur pedagoger som arbetar i grundskolans senare år upplever hur det är att arbeta med elever som har svenska som andraspråk, och vilka svårigheter som kan uppstå. Undersökningen genomfördes med kvalitativa intervjuer på en skola i mellersta Sverige. De intervjuade i studien är totalt fyra stycken: en SVA-lärare, en NO-lärare och två SO-lärare. Resultatet visar att samtliga lärare är medvetna om att det är viktigt att arbeta med språket även i ämnesundervisnigen, men olika faktorer gör att det är svårt att genomföra detta i praktiken. Dessa faktorer är: tidsbrist, stora nivåskillnader mellan eleverna och att det saknas kompetens hos ämneslärarna inom området svenska som andraspråk. Slutligen kan man ej förvänta sig att de intervjuade pedagogerna och andraspråkseleverna som de undervisar ska vara representanter för hela Sveriges skolor, då undersökningen endast genomförts på en skola med fyra intervjuer med pedagoger.

El cambio de código en hispanohablantes en Suecia : Experiencias y actitudes

In this thesis it is investigated how Spanish-speakers in Sweden experience living with two languages ​​and how common it is for them to use code-switching in their everyday speech. The study has focused on not only the experiences but also the use of code-switching among Hispanics who have become bilinguals in Sweden. The study has also examined the attitudes the informants show towards code – switching.The aim of this study is to provide a picture of the experiences Spanish-speakers have of becoming bilinguals in Sweden and of learning and using Swedish as a second language. It is of interest to see how the bilinguals converse inside and outside the home and how frequent and accepted it is among the Hispanics in Sweden with the use of code-switching in different social contexts. In summary, we can see that the Hispanics in Sweden are satisfied with the linguistic development they have experienced by learning a new language and that they consider it beneficial being bilingual. The study shows that code-switching is very much used, but not fully accepted even by those who use it on a daily basis. Code-switching is in many cases not considered appropriate and it is sometimes performed unconsciously.

Muntlig framställning : att tolka och förstå kunskapskraven i nationellt prov SVA 1

Den här studien har haft som syfte att studera om kvalitetskraven i betygsskalan stämmer överens mellan nationellt prov i SVA1 och motsvarande kursplan svenska som andraspråk 1 (SVA1) samt på vilket sätt det nationella provet underlättar tolkningen av kunskapskraven i kursplanen för SVA1. Undersökningen begränsar sig till att omfatta enbart den muntliga delen, delprov A muntlig framställning. För att beskriva och analysera vilka kunskaper som anses vara eftersträvansvärda i muntlig framställning har en kvalitativ innehållsanalys genomförts som ger en grundmodell till den efterföljande kunskapsanalysen. Resultaten från studiens innehållsanalys visar fram en hur processen kring den muntliga framställningen utgår från den retoriska arbetsmodellen med ett gediget förberedande arbete som följs upp med anförande och avslutas med elevresponser. Resultatet från kunskapsanalysen visar hur eleverna behöver behärska en kombination av kunskapsformerna episteme, techné och fronesis för att uppfylla betygskraven på de högre nivåerna. Studiens slutsatser är att kvalitetskraven stämmer överens mellan det nationella provets bedömningsmatris och kursplanen i svenska som andraspråk 1 (SVA 1) vad gäller bedömningen av elevens språkliga kvaliteter. Dessutom går det att dra slutsatsen att de krav på anpassning till det retoriska sammanhanget också är krav som återfinns i kursplanen men beskrivs mer allmänt i ett språkutvecklande perspektiv vilket underlättar tolkningen av kunskapskraven i kursplanen. Studien visar hur eleven för att få det lägsta betyget (E) behöver kunskaper om en retorisk framställning och att eleven kan presentera ett förberett innehåll inför en publik.

Svenska för invandrarskap? : Språk, kategorisering och identitet inom utbildningsformen Svenska för invandrare

The overall purpose of this thesis and the four independent studies it builds upon is to examine how categorizations and identity positions are constructed and negotiated in the educational program Swedish for immigrants (SFI) both historically and among participants in the program at the beginning of the 21th century. The analytical focus is on the discourses that frame the development of the SFI program with a specific interest in categorizations and identity in relation to gender, language and national belonging. The empirical material includes historical texts (curricula, commission reports, public inquiries, political propositions, laws) from 1965 to 2010, as well as approximately 95 hours of audio and video recorded data and ethnographic field notes from five SFI classrooms. The results are presented primarily in the four articles but partly also in the thesis itself. Our analysis in the first study, that takes a sociohistorical perspective as a point of departure, indicates shifts in discourses with regards to the categories and aims of the educational program, thus, making certain identity positions more accessible than others at specific times. Using the approach of nexus analysis, the theoretical framework employed in the second study approaches language policies n terms of a dialectical elationship between policy and the learning that takes lace in the language focused classroom. Feminist and postcolonial frameworks re employed ore pecifically in the third and fourth studies. The historical nalysis presented in article three shows how the categories of “immigrant” and Swedes” ave been produced and negotiated in discourses on gender and gender quality in the SFI program since the early 1970s. The fourth study highlights he omplex relationship between gender equality and integration policies, as well as he perception of gender equality as a central part of Swedishness”, negotiated in he everyday conversations in the SFI classroom. Overall, the results illuminate he circulation of discourses both cross ime and between policy and classrooms. oreover, it contributes to a critical discussion about the intersection of language, ender and national elonging in the negotiation of boundaries between insiders and outsiders in Swedish society.

LA ANSIEDAD Y SU RELACIÓN CON LA EXPRESIÓN ORAL EN EL APRENDIZAJE DE LENGUAS EXTRANJERAS : Una elaboración de revisión sistemática de la literatura

La importancia de la dimensión afectiva que acompaña el proceso de adquisición de lenguas extranjeras es indiscutible. Sin embargo, a pesar de esta realidad, y de la evolución de los enfoques comunicativos como métodos de enseñanza de idiomas, la literatura continúa asegurando la existencia de aprensión lingüística en el aula y su efecto debilitador en el proceso de aprendizaje de una nueva lengua. Este estudio tiene como objetivo examinar cómo el aprendiz experimenta la variable de la ansiedad al expresarse oralmente y en qué medida el profesorado de lenguas extranjeras puede lograr crear condiciones en la clase que reduzcan los niveles de ansiedad. En este trabajo utilizamos la revisión sistemática de literatura como estrategia de investigación, un método que constituye una buena herramienta, permitiéndonos sintetizar coherentemente, de forma rigurosa, los resultados de los estudios empíricos sobre el fenómeno de la ansiedad. Los análisis revelan, en primer lugar, que los síntomas experimentados por aprendices de una nueva lengua suelen manifestarse en cada uno de los niveles que integran al individuo, en un nivel emocional, psicológico, fisiológico, de comportamiento y psicopedagógico; en segundo lugar, los investigadores plantean diversas estrategias a nivel psicológico, pedagógico y socio ambiental con el objetivo principal de incrementar en el aprendiz una serie de recursos personales para hacer frente a la ansiedad. Comentamos las implicancias pedagógicas de estos resultados para una mejor comprensión de la ansiedad y del aprendizaje de una lengua extranjera.

The priority of temporal aspects in L2-Swedish prosody : Studies in perception and production

Foreign accent can be everything from hardly detectable to rendering the second language speech unintelligible. It is assumed that certain aspects of a specific target language contribute more to making the foreign accented speech intelligible and listener friendly, than others. The present thesis examines a teaching strategy for Swedish pronunciation in second language education. The teaching strategy “Basic prosody” or BP, gives priority to temporal aspects of Swedish prosody, which means the temporal phonological contrasts word stress and quantity, as well as the durational realizations of these contrasts. BP does not prescribe any specific tonal realizations. This standpoint is based on the great regional variety in realization and distribution of Swedish word accents. The teaching strategy consists virtually of three directives: · Stress the proper word in the sentence. · Stress proper syllables in stressed words and make them longer. · Lengthen the proper segment – vowel or subsequent consonant – in the stressed syllable. These directives reflect the view that all phonological length is stress-induced, and that vowel length and consonant length are equally important as learning goals. BP is examined in the light of existing findings in the field of second language pronunciation and with respect to the phonetic correlates of Swedish stress and quantity. Five studies examine the relation between segment durations and the categorization made by native Swedish listeners. The results indicate that the postvocalic consonant duration contributes to quantity categorization as well as giving the proper duration to stressed syllables. Furthermore, native Swedish speakers are shown to apply the complementary /V: C/ - /VC:/ pattern also when speaking English and German, by lengthening postvocalic consonants. The correctness of the priority is not directly addressed but important aspects of BP are supported by earlier findings as well as the results from the present studies.

Attitudes towards the minority variety Caló in the south of Spain : a sociolinguistic study

Caló is a variety spoken by the Spanish Calé (i.e. the Roma). It belongs to a group of languages referred to as “Para-Romani”, characterized by Romani vocabulary, but largely non-Romani morphology, phonology and syntax, in the case of Caló deriving from Spanish. According to previous research carried out – with focus on the vocabulary and the grammar of this variety – Caló is on its way to extinction. However, there is an expressed interest in reintroducing a form called “Romanó-Caló”. Attitudes play an important role in minority language maintenance as well as in order for a revitalization project to be successful. The aim of this study is to measure the attitudes that both Calé and non-Calé have towards Caló and Caló speakers, a type of study never carried out in the past. The methods applied are both direct and indirect. In total, 231 informants listened to different recordings of voices acting as either a “Spanish speaking person” or a “Caló speaking person”, a technique referred to as ‘matched guise’, answering questions related to the voices on attitude scales. Furthermore, 182 of the informants rated their agreement or disagreement to positive and negative items towards Caló and its speakers on a Likert scale. The results of the analysis indicate that the attitudes differ towards Caló and Caló speakers, depending on the informant’s (a) ethnicity (b) contact with Caló as well as with Caló speakers, and (c) gender. It is those who – in their own opinion – belong to the ethnic group Calé, as well as those who claim that they have some contact with the variety and its speakers, who show positive attitudes in both parts of the study. The women also show more positive attitudes than the men. It is also possible to note positive attitudes towards the variety and its speakers among the subjects with a high level of knowledge of Caló words, as well as among those with the highest willingness to use Caló. These observations suggest that a revitalization project of the variety Caló has a clear chance of being successful.

Reading That Matters : A Literature Review on Meaningful Reading Experiences in the EFL Classroom

This thesis is a literature review on literature reading in the English as a Foreign Language (EFL) and the English as a Second Language (ESL) classroom, of mainly upper secondary schools. The underlying objective for this work is that meaningful reading experiences can have a positive impact on a developing young individual on his or her way into adulthood. The aim of this thesis is to explore what theories and methods are used when trying to create prerequisites for meaningful reading experiences, and how these experiences actually are realized. Qualitative methods are mainly used, except for a small section of the methodology of finding the sources, which is quantitative in nature. Since very little previous research has been done in the field, the six sources used in this review are internationally spread over five continents. They are mainly analyzed from a theoretical background of reader response and critical literacy perspectives. The main findings show that a number of theoretical approaches and methodologies can be useful in creating meaningful reading experiences. What may have proven most effective was addressing actual problems in the students’ everyday lives through applied critical literacy.

What affects recognition most – wrong wordstress or wrong word accent?

In an attempt to find out which of the two Swedish prosodic contrasts of 1) wordstress pattern and 2) tonal word accent category has the greatest communicative weight, a lexical decision experiment was conducted: in one part word stress pattern was changed from trochaic to iambic, and in the other part trochaic accentII words were changed to accent I.Native Swedish listeners were asked to decide whether the distorted words werereal words or ‘non-words’. A clear tendency is that listeners preferred to give more‘non-word’ responses when the stress pattern was shifted, compared to when wordaccent category was shifted. This could have implications for priority of phonological features when teaching Swedish as a second language.

The relative perceptual weight of two Swedish prosodic contrasts

Abstract. In addition to 9 vowel and 18 consonant phonemes, Swedish has three prosodic phonemic contrasts: word stress, quantity and tonal word accent. There are also examples of distinctive phrase or sentence stress, where a verb can be followed by either an unstressed preposition or a stressed particle. This study focuses on word level and more specifically on word stress and tonal word accent in disyllabic words. When making curriculums for second language learners, teachers are helped by knowing which phonetic or phonological features are more or less crucial for the intelligibility of speech and there are some structural and anecdotal evidence that word stress should play a more important role for intelligibility of Swedish, than the tonal word accent. The Swedish word stress is about prominence contrasts between syllables, mainly signaled by syllable duration, while the tonal word accent is signaled mainly by pitch contour. The word stress contrast, as in armen [´arːmən] ‘the arm’ - armén [ar´meːn] ‘the army’, the first word trochaic and the second iambic, is present in all regional varieties of Swedish, and realized with roughly the same acoustic cues, while the tonal word accent, as in anden [´anːdən] ‘the duck’ - anden [`anːdən] ‘the spirit’ is absent in some dialects (as well as in singing), and also signaled with a variety of tonal patterns depending on region. The present study aims at comparing the respective perceptual weight of the two mentioned contrasts. Two lexical decision tests were carried out where in total 34 native Swedish listeners should decide whether a stimulus was a real word or a non-word. Real words of all mentioned categories were mixed with nonsense words and words that were mispronounced with opposite stress pattern or opposite tonal word accent category. The results show that distorted word stress caused more non-word judgments and more loss, than distorted word accent. Our conclusion is that intelligibility of Swedish is more sensitive to distorted word stress pattern than to distorted tonal word accent pattern. This is in compliance with the structural arguments presented above, and also with our own intuition.

Duas vertentes da ontogênese da linguagem no desenvolvimento cognitivo

Este estudo pretende trazer uma contribuição à discussão da relação linguagem-cognição, através do exame de um aspecto restrito do problema: a hipótese de uma base cognitiva para aquisição de linguagem. O modelo teórico piagetiano é analisado em sua explicação da ontogenese da linguagem como resultante das construções da inteligência sensório-motora. Alguns de seus aspectos são questionados, a possibilidade de sua explicitação em forma de hipótese verificável é examinada e a literatura é analisada em busca de evidências relevantes. A principal lacuna constatada é a visão de linguagem restrita a aspectos de desempenho, sendo levado em conta apenas o começo da emissão de palavras na quase totalidade das pesquisas. Ainda dentro de uma perspectiva construtivista, o esboço de um novo modelo teórico é proposto, incluindo a discussão da ontogenese da compreensão de linguagem. Hipóteses decorrentes da proposta teórica, especialmente a de início da possibilidade de tratar o signo linguístico antes do estágio VI, são formuladas e verificadas por pesquisa empírica. Esta inclui um estudo longitudinal e outro transversal do desenvolvimento linguístico e cognitivo de 45 crianças entre 8 e 18 meses. O desenvolvimento da compreensão é comparado em diversos aspectos ao da produção ou fala. Verifica-se que o primeiro começa mais cedo, é mais rápido e atinge um vocabulário maior e um nível mais complexo na faixa etária estudada. Há evidências ainda de diferenças no papel da imitação na construção do vocabulário nas duas vertentes. Observa-se um início de resposta mais generalizada e sistemática à linguagem a partir de nove meses, ocasião em que a criança se mostra capaz de coordenação de reações circulares secundárias e quando consegue reconstruir mentalmente um objeto invisível a partir de uma fração visível. Considera-se que esta resposta já envolve a decodificação de signos e a diferenciação significante-significado, numa etapa preliminar de um processo evolutivo que se entrelaça com a formação de conceitos. Os dados nao permitem a identificação de prê-requisitos cognitivos para aquisição de liguagem, mas dois aspectos podem ser destacados como correlatos do início do processo de compartilhar o signo linguístico: a possibilidade da criança compreender que tem um nome e responder a ele e uma intencionalidade primitiva. Os resultados apoiam as hipóteses formuladas e sugerem que as construções finais do período sensório-motor não são condições necessárias para aquisição de linguagem e que esta não ê consequência direta do desenvolvimento cognitivo. Novos estudos são necessários para suprir as limitações desta pesquisa e verificação das implicações decorrentes dos resultados obtidos.
