Esta dissertação descreve e analisa a estrutura argumental e as classes verbais da língua Dâw (família Nadahup, Amazonas). Estudamos os verbos dessa língua do ponto de vista semântico e sintático, identificando classes e subclasses de acordo com o comportamento morfossintático das raízes verbais. Além disso, avaliamos as hipóteses descritivas e explicativas das classes verbais identificadas por Martins (2004), primeira pesquisadora a abordar a morfossintaxe Dâw. Nosso arcabouço teórico é a teoria de estrutura argumental desenvolvida por Hale & Keyser (2002), que propõe uma análise da sintaxe e da semântica dos itens lexicais por meio da estrutura argumental sistema de relações estruturais estabelecidas entre o núcleo e seus argumentos, dentro de estruturas sintáticas projetadas pelo próprio núcleo. Por meio de testes linguísticos variados, incluindo alternância de valência e julgamento de (a)gramaticalidade, reclassificamos as nove classes verbais identificadas por Martins (2004) em três classes de acordo com a valência do verbo: classe dos verbos intransitivos, classe dos verbos transitivos e classe dos verbos bitransitivos. Martins (2004) afirma que, na sentença, os verbos podem mudar de tom devido à presença de um morfema tonal transitivizador ou intransitivizador. Contudo, mostramos neste trabalho que o sistema tonal da língua, no nível da sentença, é previsível. Desse modo, independentemente do processo de aumento de valência envolvido, percebemos que a mudança tonal dos verbos decorre devido ao fraseamento fonológico das sentenças. Quanto ao processo de transitivização, este identificou subclasses de verbos intransitivos: verbos alternantes e verbos nãoalternantes. As restrições de alternância devem-se à estrutura argumental de cada tipo verbal. No caso dos verbos intransitivos alternantes ou inacusativos, observamos que eles são formados a partir de estrutura diádica composta, que projeta um especificador interno e um complemento, o que lhe permite alternar entre uma forma intransitiva e transitiva. No caso dos verbos não-alternantes encontramos três padrões: verbos denominais e inergativos, formados a partir de uma estrutura argumental monádica (que não projeta especificador interno), o que impede a alternância; verbos inacusativos nãoalternantes, formados a partir de uma estrutura monádica que toma como complemento uma estrutura diádica básica verbos desse tipo não alternam, pois eles não são formados por uma estrutura diádica, mas contêm tal estrutura; e ve b s e jetiv is, formados a partir de uma cópula que toma como complemento um adjetivo. Uma vez que raiz e núcleo verbal possuem conteúdo fonológico pleno (não vazio), não é possível fazer conflation entre núcleo e raiz, o que impede que o predicado verbal seja formado. Essa estrutura explica a agramaticalidade desses verbos frente ao processo de transitivização automática. Também testamos a sintaxe e a semântica da intransitivização (construções incoativas, voz passiva, reflexiva e média). De modo geral, percebemos que não há morfologia específica para a construção de sentenças médias, incoativas ou anticausativas. Não existem passivas em Dâw; no lugar desta voz, os falantes produzem sentenças incoativas ou com o sujeito subespecificado. As sentenças reflexivas são geradas por meio de pronomes reflexivos na posição de objeto da sentença. Por fim, vimos que objetos diretos de sentenças transitivas são marcados pelo morfema {-uuy\'} analisados por nós como MDO. Sua aplicação está condicionada a restrições semânticas de definitude e animacidade / This thesis describes and analyzes the argument structure and verbal classes of the Dâw language (Nadahup family, Amazon). We studied the verbs of that language from the semantic and syntactic perspective, identifying classes and subclasses according to the morphosyntactic behavior of verbal roots. Furthermore, we evaluated the descriptive and explanatory hypotheses of verb classes identified by Martins (2004), the first researcher to address Dâw morphosyntax. Our theoretical framework is the theory of argument structure developed by Hale & Keyser (2002), which proposes an analysis of the syntax and semantics of lexical items by means of the argument structure the pattern of structural relations between the head and its arguments within syntactical structures projected by the head itself. Through various language tests, including verbal valency alternation and judgment of (a)grammaticality, we reclassified the nine verb classes identified by Martins (2004) into three classes according to the verbal valency: the classes of intransitive verbs, transitive verbs and bitransitive verbs. Martins (2004) states that, in the sentence, the verbs may change in tone due to the presence of a transitivizing or intransitivizing tonal morpheme. However, we show in this paper that the tonal system of the language is predictable at the sentence level. Thus, regardless of the valency-increasing process involved, we realized that the tonal change of verbs arises due to the phonological phrasing of sentences. Regarding the transitivization process, subclasses of intransitive verbs were identified: alternating and non-alternating verbs. The restrictions on alternation are due to the argument structure of each verb type. In the case of unaccusative or alternating intransitive verbs, we observed that they are formed from a composite dyadic structure, projecting an internal specifier and a complement, which allows them to switch between intransitive and transitive forms. In the case of non-alternating verbs we found three patterns: denominal and unergative verbs, based on a monadic argument structure (that does not project internal specifier) that prevents alternation; non-alternating unaccusative verbs based on a monadic structure that takes a basic dyadic structure as a complement verbs of this type do not alternate because they are not formed by a dyadic structure, but contain such a structure n e jectiv l ve bs, f me f m c p l ve b th t t kes n jective s complement. Since the root and verbal head have full (non-empty) phonological content, no conflation is possible between head and root, which prevents the formation of the verbal predicate. This structure explains the agrammaticality of these verbs with regard to the automatic transitivization process. We also tested the syntax and semantics of intransitivization (inchoative constructions, passive, reflexive and middle voices). In general, we found that there is no specific morphology for constructing middle, inchoative or anticausative sentences. There are no passives in Dâw; in place of this voice, the speakers form sentences that are inchoative or have a subspecified subject. Reflexive sentences are created using reflexive pronouns in the position of the object of the sentence. Finally, we found that direct objects of transitive sentences are marked by the {-uuy\'} morpheme analyzed by us as DOM. Its use is subject to semantic constraints of definiteness and animacy

Este trabalho pretende levantar questões relativas ao uso e aos efeitos provocados pela utilização de estratégias argumentativas no discurso. Para exemplificar a importância de tais estratégias na construção da significação no uso da linguagem, elegemos como objeto de análise um discurso em especial, o pedagógico, e, dentro dele, optamos pelo estudo das avaliações no ensino superior, especificamente, das provas escritas, representantes do poder da linguagem no processo ensino/aprendizagem e do conflito existente na relação professor-aluno. A partir deste recorte metodológico, repensaremos, em especial, as figuras de argumentação e retórica, estratégias discursivas inesperadas - causam o efeito de surpresa no discurso - e privilegiadas, na medida em que permitem analisar não apenas o fazer persuasivo do enunciador, bem como a construção do ethos dos sujeitos envolvidos na situação comunicativa. Acreditamos que em todos os tipos de discurso a linguagem pode ser utilizada não apenas para convencer um interlocutor, mas para persuadi-lo. Tal fato nos leva a buscar no discurso do aluno quais são as estratégias utilizadas para este fim, e a tentar identificá-las dentro de um quadro teórico e metodológico discursivo. Para tanto, empreendemos um retorno às origens histórico-pedagógicas da avaliação, recorremos à Retórica Aristotélica e às Neo-Retóricas, à Teoria Semiótica de Greimas, à Teoria dos Gêneros do Discurso de Bakhtin, e a estudos sociossemióticos e discursivos que privilegiam questões como a construção da identidade individual e social dos sujeitos por meio do discurso e os aspectos interacionais envolvidos nas relações sociais. / The proposal of this work is to produce questions about the use of argumentatives strategies in the discourse, as well as questions about the effect of this use. To analyze the importance of these strategies during the construction of the meaning, we choose a special type of discourse, the pedagogical discourse, and inside of it, we have decided to analyze the proofs in the university, more specifically, the written proofs, because they are representative of the language´s power in the education and learning process and of the existing conflict between professor and students. From this method, we will analyze, in special, the argument and rhetoric figures and the unexpected and privileged discoursive strategies - because they cause surprise in the discourse and allow to analyze the construction of the ethos of the involved people in the communication situation. We believe that the language can be used to persuade an interlocutor and to convince him, not importing the type of discourse used. This fact makes us to search in the students´ discourse the used strategies and trying to identify them into inside of a theoretical, methodologic and discoursive frame. With this objective, we made a visit to the historical and pedagogical origins of the proofs, we appeal to the Aristotelian Rhetoric and the Neo-Rhetorical, to the Greimas´ Semiotics Theory and the Bakhtin´s work, and to the sociossemiotic and discoursive studies that privilege questions, as the construction, through the discourse, of the individual and social identity of the people, and aspects that are involved in the social relations.

Esta dissertação tem como objetivo investigar as propostas de ensino de produção de texto argumentativo, no apostilado de Língua Portuguesa, elaborado pela Secretaria da Educação do Estado de São Paulo, em 2008, e utilizado na rede pública de ensino desde então. Neste trabalho, buscamos (1) descrever o encaminhamento das atividades de ensino de redação de textos argumentativos no apostilado de Língua Portuguesa do Estado de São Paulo, (2) analisar as atividades de produção escrita que abordam o ensino do texto argumentativo (resenha, artigo de opinião e dissertação escolar) e (3) estabelecer o confronto entre as atividades de ensino de redação do texto argumentativo no Caderno do Aluno, as orientações dirigidas ao professor no Caderno do Professor e as prescrições desse conteúdo no Currículo de Língua Portuguesa. Fundamentamos a análise com o apoio teórico do conceito de texto de Bakhtin e o Círculo (1926; 1928; 1929; 1952-53; 1959-61), articulado a outros conceitos do pensamento bakhtiniano - signo ideológico, enunciado e linguagem -, o que contribui para uma concepção da linguagem como atividade humana. Nessa perspectiva, o texto é considerado como uma teia de relações entre textos, que traduzem ações humanas, marcadas social, cultural e historicamente. Recorremos, também, às contribuições do campo de estudos em argumentação denominado Nova Retórica (PERELMAN; OLBRECHTS-TYTECA, 2005), que tratam do conceito de argumentação, dos elementos necessários à argumentação e dos procedimentos argumentativos utilizados na construção da argumentação; elementos que nos auxiliam no aprofundamento da discussão sobre texto argumentativo. Com base nessa fundamentação, descrevemos e analisamos quatro unidades didáticas chamadas Situações de Aprendizagem, presentes em três volumes do apostilado de Língua Portuguesa, composto por doze fascículos, distribuídos aos alunos e professores do Ensino Médio. Nas atividades escolhidas, o ensino do texto argumentativo em três gêneros resenha (1ª série), artigo de opinião (2ª série) e dissertação escolar (3ª série) e a proposta de escrita nos gêneros mencionados ocorrem pela primeira vez no apostilado de Língua Portuguesa do Ensino Médio. A partir da análise desse objeto de ensino, verificamos que há um embate entre o que está prescrito no Currículo de Língua Portuguesa (2010) e o que, efetivamente, é proposto ao aluno, no que se refere ao conceito de texto e aos conteúdos de ensino do texto argumentativo. Os resultados obtidos mostraram que, no referencial curricular, o texto é considerado como um produto vivo da interação social, e o texto argumentativo deve ser a expressão de um posicionamento crítico diante da sociedade. Nas atividades analisadas, o texto é apresentado como um modelo a ser seguido, favorecendo uma prática escolar pouco voltada à cidadania, e transforma-se em uma tarefa a ser entregue ao professor, na qual o aluno não se constitui como autor, mas como reprodutor de textos. Acreditamos que entre as prescrições e as práticas escolares ainda temos um conhecimento de texto argumentativo genérico e abstrato. / This thesis has the purpose to investigate teaching proposals of argumentative texts into Portuguese booklets from Sao Paulo State Ministry of Education, which has been applied in the public school system since 2008. In this study, we aimed (1) to describe writing activities routing, (2) to analyze writing texts that attempt to teaching proposals of argumentative texts (report, text opinion and school essay) and (3) to seek confrontation between teaching activities of argumentative text from the Students Notebook, the issue guidance to teachers from the Teachers Notebook, and content prescription inside Portuguese National Curriculum. This theoretical analysis is based on Bakhtin and the Circle Concepts (1926; 1928; 1929; 1952-53; 1959-61) connected to other Bakhtinian concepts ideological sign, proposition and language that contribute to a language conception as a human activity. Accordingly, a text is considered a net of relationships between texts translating human actions that are social, cultural and historical marked. We are also based on studies from the argumentative field called New Rhetoric (PERELMAN; OLBRECHTS-TYTECA, 2005) concerning about argumentative concepts, basic elements necessary to argue into and argumentative procedures discussions used to build this specific kind of texts. All of these theories help us to get deeper into argumentative discussion. In this manner, we described and analyzed four didactic units called Learning Situations, presented on the three volumes of Portuguese Booklet formed by twelve fascicles, distributed to High School teachers and students. In the selected texts, the teaching process of three types of argumentative texts report (First High School), text opinion (Second High School) and school essay (Third High School) happens at first inside the Portuguese High School Booklet. From this educational target analysis, we verified the confrontation between prescribed elements at Portuguese National Curriculum and what effectively is proposed in the classroom referred to contents and concepts of teaching argumentative texts. The results showed that in the Portuguese National Curriculum the text is considered a product of critical placement in front of society. In the analyzed activities, the text is showed as a model to be followed promoting a school practice that is not looking at citizenship process, and it becomes just a task for a teacher where the student is not an author but just a person that is writing something for someone. We believe that between prescription and practice there is a limited and abstract knowledge about the importance of text production.

A meta da presente tese é analisar as orações não-finitas em Karitiana. Esta é uma língua Ameríndia falada atualmente por 400 pessoas que habitam a Terra Indígena Karitiana. A reserva Karitiana está localizada a 95 quilômetros ao sul da área urbana de Porto Velho, Rondônia, Brasil. A língua é a única representante do ramo Arikém, família Tupi. A presente pesquisa investiga as diferenças entre as orações subordinadas que funcionam como orações subordinadas adverbiais, relativas e completivas, bem como a nominalização oracional e as orações infinitivas marcadas pelos sufixos e , respectivamente. Apesar de a língua não apresentar morfologia de tempo, modo ou concordância em subordinadas, ela possui várias outras características, tais como núcleos aspectuais, voz, variação na ordem de palavras (SOV ou OSV), morfologia de foco do objeto, o que sugere que se trata subordinação e não nominalização (Storto 1999, Storto 2012, Vivanco 2014). Mostramos ainda que as orações encaixadas Karitiana podem ser modificadas por advérbios, negação e evidenciais que estão associados a orações ou sintagmas verbais. Esta pesquisa levantou uma discussão que tem sido amplamente abordada na literatura sobre as orações subordinadas nãofinitas em línguas Ameríndias. A literatura sobre essas orações não-finitas mostra que muitos autores que assumem que elas são nominalizações utilizam dois argumentos: (1) a falta de traços finitos e (2) o fato de algumas línguas exibirem marcas de caso. Os argumentos com base no item (2) supramencionado não parece muito convincentes para assumirmos uma análise de nominalização em Karitiana, visto que orações subordinadas finitas em várias línguas podem ser usadas como complemento verbal e receber marcas de caso. A nossa análise apresentada nesta tese assume que a falta de traços finitos não significa necessariamente que estas orações sejam nominalizadas porque elas exibem em suas estruturas várias características de orações ativas, tais como núcleos funcionais de voz, aspecto, advérbios, negação e evidenciais. Tipologicamente, esses núcleos funcionais estão associados a orações ou a sintagmas verbais. E, internamente à língua, eles estão também relacionados a orações ou a sintagmas verbais tanto em ambientes finitos quanto em ambientes não-finitas. / The main aim of this dissertation is to analyze non-finite clauses in Karitiana. Karitiana is an endangered Amerindian language spoken today by approximately 400 people who live in a reservation located 59 miles south of the urban area of Porto Velho, the capital of the state of Rondônia, Brazil (Amazonian region). The language is the unique representative of the Arikém branch, one of the ten linguistic groupings identified inside the Tupian family. The current research investigates differences among embedded clauses that function as adverbial, relative, and complement clauses in Karitiana, as well as nominalization and infinitival embedding marked respectively by the suffixes and . Even though subordinate clauses in Karitiana do not display any finite morphology of agreement, tense, or mood, it is true that the language shows many other functional heads such as morphemes of causativization, passivization, and object focus construction, as well as aspectual nuclei, and word order variation (SOV, OSV), suggesting that they are clauses and not nominalizations (Storto 1999; Vivanco 2014). Furthemore, we show that Karitiana embedded clauses can be modified by adverbs, negation and evidentials that are associated with clauses or verbal phrases. The literature on non-finite clauses in Amerindian languages shows that many specialists in these languages have claimed that these clauses are nominalized based on two arguments: (1) lack of finite traits and (2) the fact that some of these languages display case-marking. The argument that the presence of case-marking in subordination characterizes them as nominalizations seems to be unconvincing because finite subordinate clauses in several languages can be used as verbal complement and can be marked with case. In our analysis, the lack of finite features also does not necessarily mean that these clauses are nominalizations, since Karitiana subordinate clauses exhibit other properties of active clauses such as functional heads: voice, aspect, adverbs, negation, and evidentials. Typologically, these functional heads are associated with clauses and, internally to the language, they are also correlated with clauses and verbal phrases, functioning either in matrix clauses or in subordinate clauses.

Nesta dissertação, o objetivo é investigar um conjunto de redações do Exame Nacional do Ensino Médio (Enem)/2012, analisando as relações dialógicas estabelecidas pelos escreventes a partir da interação ativa com as vozes reportadas para a defesa de um ponto de vista sobre o tema: O movimento imigratório para o Brasil no século XXI. Desde 2009, o Enem seleciona candidatos para o ingresso no ensino superior e a redação é o instrumento que solicita a elaboração de um texto dissertativo-argumentativo. A partir do total de 2720 redações cedidas pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), o corpus foi constituído por 121 redações, segundo dois critérios: (a) a faixa de desempenho de 200 a 1000 pontos, respeitando a diversidade de notas, e (b) as cinco regiões brasileiras, marcando a representatividade regional. A fundamentação teórica deste trabalho centra-se na perspectiva dialógica da linguagem de Bakhtin e o Círculo, principalmente, nos conceitos de enunciado concreto e discurso citado, e na perspectiva ideológica dos estudos de letramento. Assumindo o trabalho com a escrita como um processo de compreensão responsiva, esta pesquisa buscou compreender cada texto como uma réplica ativa à proposta de redação e aos discursos oficiais que dela ecoam. No conjunto das redações, foram identificados quatro tipos de réplicas, que serviram como eixos norteadores para a análise dos modos heterogêneos de como os escreventes responderam às instruções objetivas da proposta e ao tema da imigração: (i) réplicas à exigência dissertativa; (ii) réplicas aos textos da coletânea, (iii) réplicas à imagem da identidade nacional e (iv) réplicas à história oficial do Brasil. Dentro de cada uma dessas réplicas, os resultados mostraram que os escreventes utilizaram procedimentos linguístico-discursivos para a construção do texto argumentativo, tais como: citações nos diferentes estágios composicionais da dissertação, paráfrases associadas à síntese, cópia e imitação dos textos da coletânea, construções referenciais para a caracterização do Brasil, como o uso de slogans, a mobilização de alusões históricas e narrativas da colonização. Tais procedimentos foram usados para assumir posicionamentos polêmicos e não polêmicos, alguns empregados com tendência à reprodução da palavra alheia e outros com vistas a sua reelaboração. Sob um olhar dialógico-axiológico, a análise da apreensão dos discursos de dentro e de fora da coletânea constatou não só o engendramento ativo dos sujeitos na produção de sentidos, mas os seus direcionamentos para os interlocutores presumidos e para as vozes institucionais dentro da rede de relações que envolve o projeto de escrita na avaliação do Enem. As réplicas puderam mostrar percursos discursivos construídos no diálogo com diferentes repertórios sociais, culturais e linguísticos, sinalizando que o trabalho com a escrita não está desvinculado dos contextos sócio-históricos das práticas letradas dos escreventes, refletindo e refratando os modelos normativos. / In this dissertation, the goal is to investigate a collection of essays from the National Secondary Brazilian Examination (Enem)/2012, analyzing the dialogic relations established by the writers from the active interaction with the reported voices to defend a point of view on the topic \"the immigration movement to Brazil in the 21st century\". Since 2009, Enem selects candidates for admission to higher education and the writing is the instrument that calls for the development of a dissertative-argumentative text. From the total of 2720 essays provided by the National Institute for Educational Studies Anísio Teixeira (INEP), the corpus was consisted of 121 essays, according to two criteria of selection: a) the performance range of 200-1000 points, respecting the diversity of scores, and b) the five Brazilian regions, marking the regional representation. The theoretical foundation of this work focuses on the dialogic language perspective of Bakhtin and the Circle, mainly, the concepts of \"utterance\" and \"quoted speech,\" and the ideological perspective of the literacy studies. Assuming the job with writing as a process of responsive understanding, this research sought to understand each text as an active response to the writing proposal and to the official discourses. In all the texts, four types of responses were identified, which served as a guide for the analysis of the heterogeneous modes of how the participants answered to the instructions of the proposal and to the issue of immigration: (i) responses to the dissertation requirement; (ii) responses to the texts of the collection, (iii) responses to the image of national identity and (iv) responses to the official history of Brazil. Within each of these responses, the results showed that the subjects used linguistic-discursive procedures for the construction of the argumentative text, such as: quotes in different compositional stages of the dissertation, paraphrases associated with synthesis, copy and imitation of the texts from the collection, characterization of Brazil as the use of slogans, the mobilization of historical allusions and narrative of colonization. These procedures were used to take controversial positions and not controversial ones, some employed with the tendency to reproduce the alien word and others with the tendency to remake them. Under a dialogical axiological perspective, the analysis of the comprehension of the inside and outside discourses of the collection found not only the active gendering of the subjects in the production of meanings, but their directions for the presumed actors and to the institutional voices within the network relationships of the writing project on the assessment of Enem. The responses could show discursive routes constructed in dialogue with different social, cultural and linguistic repertoires, signaling that the work with writing is not disconnected from the socio historical contexts of the student´s literate practices, reflecting and refracting the normative models.

This dissertation is an extended argument for the syntactic structure proposed in (1), referred to as the 'VICTR Hierarchy' after the initials of the five functional heads it comprises: (1) [VolitionP Volition [InitiationP Initiation [ConsecutionP Consecution [TransitionP Transition [ResultP Result [VP ] ] ] ] ] ] The VICTR Hierarchy is a hierarchy of functional heads corresponding to the part of the clause generally known in the minimalist literature as `vP' or the `thematic domain'. Nominal arguments are merged in the specifiers of one or more of these heads and receive their thematic interpretations on the basis of their merged positions. Evidence for a model of thematic roles and syntactic argument structure based in the VICTR Hierarchy is presented for a range of domains, with a focus on 'split intransitivity'. Split intransitivity is explored initially in regard to English, with close consideration of a range of split intransitive diagnostics (e.g. 'out'-prefixation, the resultative construction); a VICTR account of these patterns is presented. A VICTR account of auxiliary selection patterns in Western European languages is also given. This is followed by analysis of split intransitive case and agreement systems. A formal account of the case and agreement patterns in these languages based in the VICTR hierarchy is presented, derived in part from the inherent case theory of ergativity (Legate 2002, Aldridge 2004 and others) and drawing on a detailed typology. The dissertation then proceeds to detailed analysis of the semantic basis of split intransitive alignment in two languages, Basque and Georgian. Other split intransitive behaviours in these languages are also considered in VICTR terms. Throughout, the VICTR approach is compared to other approaches to split intransitivity following Perlmutter's (1978) Unaccusative Hypothesis. The VICTR Hierarchy is also compared to the similar proposal of Ramchand (2008). It is argued that the VICTR Hierarchy accounts more readily than these other approaches for the particular classes of verbs identified by split intransitivity diagnostics in the languages considered, and also for cross-linguistic variation in split intransitive behaviours. Much support, with some caveats, is also found in the data considered for the applicability of Sorace's (2000) Auxiliary Selection Hierarchy (ASH) to a range of split intransitive phenomena cross-linguistically. Together with acquisitional considerations, the VICTR features are argued to allow for a formalisation of the patterns described by the ASH.

Critical Thinking has been identified in the Common Core State Standards (CCSS) and Next Generation Science Standards (NGSS) as skills needed to prepare students for advanced education and the future workforce. In science education, argument-based inquiry (ABI) has been proposed as one way to improve critical thinking. The purpose of the current study was to examine the possible effects of the Science Writing Heuristic (SWH) approach, an immersion argument-based inquiry approach to learning science, on students' critical thinking skills. Guided by a question-claims-evidence structure, students who participated in SWH approach were required to negotiate meaning and construct arguments using writing as a tool throughout the scientific investigation process. Students in the control groups learned science in traditional classroom settings. Data from five data sets that included 4417 students were analyzed cross-sectionally and longitudinally. Yearly critical thinking gain scores, as measured by Form X of Cornell Critical Thinking Test, were compared for students who experienced the SWH approach versus students who experienced traditional instruction in both elementary (5th grade) and secondary schools (6th-8th grades). Analyses of yearly gain scores for data sets that represented a single year of implementation yielded statistically significant differences favoring SWH over traditional instruction in all instances and statistically significant interactions between gender and grade level in most instances. The interactions revealed that females had higher gain scores than males at lower grade levels but the reverse was true at higher grade levels. Analyses from data sets that included two years of implementation revealed higher overall gains for SWH instruction than for traditional instruction but most of those gains were achieved during the first year of implementation. Implications of these results for teaching critical thinking skills in science classrooms are discussed in detail.

The purpose of this study was to examine the patterns of dialogue that were established and emerged in one experienced fifth-grade science teacher's classroom that used the argument-based inquiry (ABI) and the ways in which these patterns of dialogue and consensus-making were used toward the establishment of a grasp of science practice. Most current studies on ABI agree that it does not come naturally and is only acquired through practice. Additionally, the quality of dialogue is also understood to be an important link in support of student learning. Few studies have examined the ways in which a teacher develops whole-class dialogue over time and the ways in which patterns of dialogue shift over time. The research questions that guided this study were: (1) What were the initial whole-class dialogue patterns established by a fifth-grade science teacher who engaged in ABI? (2) How did the science teacher help to refine whole-class dialogue to support the agreeability of ideas constructed over time? This eighteen week study that took place in a small city of less than 15,000 in Midwestern United States was grounded in interactive constructivism, and utilized a qualitative design method to identify the ways in which an experienced fifth-grade science teacher developed whole-class dialogue and used consensus-making activities to develop the practice of ABI with his students. The teacher in this study used the Science Writing Heuristic (SWH) approach to ABI with twenty-one students who had no previous experience engaging in ABI. This teacher with 10 of years teaching experience was purposefully selected because he was proficient and experienced in practicing ABI. Multiple sources of data were collected, including classroom video with transcriptions, semi-structured interviews, after lesson conversations, and researcher's field notes. Data analysis used a basic qualitative approach. The results showed (1) that the teacher principally engaged in three forms of whole-class dialogue with students; talking to, talking with, and thinking through ideas with students. As time went on, the teacher's interactions in whole-class dialogue became increasingly focused on thinking through ideas with students, while at the same time students also dialogued more as each unit progressed. (2) This teacher persistently engaged with students in consensus-making activities during whole-class dialogue.These efforts toward consensus-making over time became part of the students' own as each unit progressed. (3) The classroom did not engage in critique and construction of knowledge necessarily like the community of science but rather used agreeing and disagreeing and explaining why through purposeful dialogic interactions to construct a grasp of science classroom practice. The findings have informed theory and practice about science argumentation, the practice of whole-class dialogue, and grasp of science practice along four aspects: (1) patterns of dialogue within a unit of instruction and across units of instruction, (2) the teacher's ability to follow and develop students' ideas, (3) the role of early and persistent opportunities to engage novice students in consensus-making, and (4) the meaning of grasp of science practice in classroom. This study provides insight into the importance of prolonged and persistent engagement with ABI in classroom practice.

The purpose of this study was to characterize ways in which teaching practice in classroom undergoing first semester implementation of an argument-based inquiry approach changes in whole-class discussion. Being that argument is explicitly called for in the Next Generation Science Standards and is currently a rare practice in teaching, many teachers will have to transform their teaching practice for inclusion of this feature. Most studies on Argument-Based Inquiry (ABI) agree that development of argument does not come easily and is only acquired through practice. Few studies have examined the ways in which teaching practice changes in relation to the big idea or disciplinary core idea (NGSS), the development of dialogue, and/or the development of argument during first semester implementation of an argument-based inquiry approach. To explore these areas, this study posed three primary research questions: (1) How does a teacher in his first semester of Science Writing Heuristic professional development make use of the "big idea"?, (1a) Is the indicated big idea consistent with NGSS core concepts?, (2) How did the dialogue in whole-class discussion change during the first semester of argument-based inquiry professional development?, (3) How did the argument in whole-class discussion change during the first semester of argument-based inquiry professional development? This semester-long study that took place in a middle school in a rural Midwestern city was grounded in interactive constructivism, and utilized a qualitative design to identify the ways in which the teacher utilized big ideas and how dialogue and argumentative dialogue developed over time. The purposefully selected teacher in this study provided a unique situation where he was in his first semester of professional development using the Science Writing Heuristic Approach to argument-based inquiry with 19 students who had two prior years' experience in ABI. Multiple sources of data were collected, including classroom video with transcripts, teacher interview, researcher field notes, student journals, teacher lesson plans from previous years, and a student questionnaire. Data analysis used a basic qualitative approach. The results showed (1) only the first time period had a true big idea, while the other two units contained topics, (2) each semester contained a similar use for the given big idea, though its role in the class was reduced after the opening activity, (3) the types of teacher questions shifted toward students explaining their comprehension of ideas and more students were involved in discussing each idea and for more turns of talk than in earlier time periods, (4) understanding science term definitions became more prominent later in the semester, with more stating science terms occurring earlier in the semester, (5) no significant changes were seen to the use of argument or claims and evidence throughout the study. The findings have informed theory and practice about science argumentation, the practice of whole-class dialogue, and the understanding of practice along four aspects: (1) apparent lack of understanding about big ideas and how to utilize them as the central organizing feature of a unit, (2) independent development of dialogue and argument, (3) apparent lack of understanding about the structure of argument and use of basic terminology with argument and big ideas, (4) challenges of ABI implementation. This study provides insight into the importance of prolonged and persistent professional development with ABI in teaching practice.
