Desenvolvimento da análise de vizinhança em mapas conceituais a partir do uso de um conceito obrigatório / Development of neighborhood analysis in concept maps considering the use of one compulsory concept

Camila Aparecida Tolentino Cicuto 06 October 2011 (has links)
Os mapas conceituais (MCs) são úteis para representar o conhecimento dos alunos e promover a aprendizagem significativa. A análise detalhada de mapas conceituais pode revelar informações latentes que não são percebidas a partir da mera leitura do seu conjunto de proposições. O presente trabalho tem como objetivo propor a análise de vizinhança (AViz) como uma forma inovadora de analisar os MCs obtidos em sala de aula. A seleção de um conceito obrigatório (CO) permite verificar como os alunos o relaciona com outros conceitos, que são denominados conceitos vizinhos (CVs). MCs (n=69) sobre as mudanças climáticas formam o primeiro conjunto de dados empíricos que ratifica o potencial da AViz. O CO selecionado foi dispersão, a fim de analisar se os alunos conseguem relacioná-lo com o caráter global desse problema ambiental. Os padrões identificados a partir da AViz sugerem que, apesar de serem submetidos a uma mesma sequência didática, nem todos os alunos conseguiram utilizar o CO de forma adequada. Isso pode ser explicado a partir da Teoria da Aprendizagem Significativa de David Ausubel, que destaca o papel fundamental dos conhecimentos prévios no processo de assimilação de novas informações. / Concept maps (CMs) are useful to represent students\' knowledge and to promote meaningful learning. The deep analysis of concept maps may reveal latent information that is not perceived from the simple reading of its propositional network. This work proposes the Neighborhood Analysis (NeAn) as an innovative way to analyze the CMs obtained in classrooms. The selection of a compulsory concept (CC) allows teachers to evaluate how the students relate it to other concepts, named neighbors (NCs). CMs (n=69) on climate change are the first set of empirical data that confirms the potential of NeAn. Dispersion was selected as CC in order to check whether students can relate it with the global perspective of this environmental problem. The patterns found from the NeAn suggest that, despite being exposed to the same didactic activities, some students could not use the CC properly. This may be explained from David Ausubel\'s learning theory, which stresses the critical role of prior knowledge in the assimilation process of new information.

Approaching Mathematical Discourse : Two analytical frameworks and their relation to problem solving interactions

Ryve, Andreas January 2006 (has links)
The driving force of conducting the two studies presented in this thesis is to examine ways that conceptual understanding and problem solving could be part of mathematics teaching, and through that, part of students' mathematical knowledge. The specific aims of the thesis are: 1) to characterize the classroom discourse of two, apparently similar, problem solving courses in teacher education and 2) to discuss the possibilities of developing two analytical approaches - the communicational approach to cognition and the dialogical approach - used for studying mathematical discourse. The two aims are elaborated on by means of data collected through audiotaped recordings and field notes from observations of problem-solving activities in engineering and teacher education. In relation to the first aim, the analysis of the classroom discourse within the two courses makes it clear that both courses displayed different kinds of discourse that could be broadly categorized in terms of: subject-oriented, didactically oriented, and problem solving oriented discourses. However, the comparisons between the two courses reveal a marked difference in the distribution of these categories of discourse. It is suggested that the introduction of explicit conceptual frameworks in teaching is of crucial importance for the topical focus of the classroom discourse, and for prospective teachers' opportunity to engage in mathematical productive discourse. The analyses of the two approaches for studying mathematical discourse reveal that the two frameworks can be further developed and the study also indicates ways in which such development can be achieved using a theory of contextualization and theories of mathematical learning. Finally, the thesis discusses theoretical and practical implications of the results, foregrounding issues of importance for the research on mathematical discourse, and for teachers and teacher educators involved in designing instructions for mathematical problem solving.

A semiotic multimodal analysis and South African case study: the representation and construction of masculinities in men's health (Sa)

Cilliers , Christiaan Petrus 06 1900 (has links)
The main question of this study was: How and in what way can a multimodal semiotic visual analysis model be developed and used for contributing to the analysis and understanding of the manner in which the Men’s Health (South Africa) magazine – as a case study – represents and constructs masculinities in South Africa? The following three subsidiary research questions were formulated to address this topic: • What is the literature revealing with reference to the media as producers of meaning in relation to masculinity and visual texts? • How and in which way can a semiotic visual analysis multimodal model be developed with the purpose of contributing to the analysis of visual texts? • What is the outcome of the visual analysis multimodal model with reference to the case study about the representation and construction of masculinities in visual texts in MH? The first aim of this research was to establish an overview of masculinities and to explore the visual representation of masculinity with reference to mediation, reality, and ideology in the media. With reference to the media as producers of meaning in relation to masculinity and visual texts, a semiotic visual analysis and social semiotics were used to unpack culture as a site of the production of meanings. The media is one of the main sources from which men receive their entertainment and information about the world. In this sense, the media makes sense of the world. Mass media plays a key role in discourse and constructing the relationships between reality and ideology. During this construction, the media reflects on existing opinions and attitudes in society. A quantitative content analysis and a qualitative semiotic multimodal visual analysis were conducted on 27 visual texts purposively selected from MH to include editions from July 2010 to June 2011. This population covered 12 front covers, 12 editorials and three flip covers. The developed visual multimodal model was tested qualitatively on nine visual texts since these texts included the front covers, flip covers and editorials of the three editions with flip covers. v A second major aim of the study was to establish the way in which a semiotic visual analysis multimodal model needed to be developed and used for analysing visual texts, as well as for analysing the visual texts according to the multimodal model in order to understand how the multimodality and social semiotic resources were applied in MH to represent and construct masculinities. The rationale for the development and design of this model was based on the premise that a basic understanding of semiotics and visual language was needed. Without such an understanding, the vast amounts of visual messages that confront the reader would remain incomprehensible. Consequently, a productive dialogue in relation to visual communication cannot take place. The multimodal model developed in this thesis highlights visual text layout, in conjunction with language-in-use, that does not occur in isolation and that is deeply reliant on other forms of making meaning. The heptagon multimodal model consists of concept maps of the six functions of the designed hexagon model. This multimodality approach includes analysing simultaneously occurring semiotics and their various roles in conjunction with detailed, all-inclusive discourses. In the quantitative content analysis and the qualitative multimodal semiotic analysis, the six components of the developed heptagon model (visual grammar, positioning, typography, colour, modality, and iconography) are illustrated. The quantitative research supported the main research design, i.e. the qualitative multimodal semiotic analysis. It is envisaged that the development and construction of a multimodal semiotic model will make a contribution to the scholarly field of semiotic analysis. By discussing the fluidity of the variations of masculinities and male identities, by giving a brief overview of the role of the media in constructing masculinities, and by focusing on the discourses that took place in MH, the researcher creates an awareness of the inherited patriarchal masculinities by recommending envisioned masculinities to be inclusive as a component of the solution. This approach is illustrated by the use and findings of the multimodal semiotic visual analysis. / Communication Science / D. Litt. et. Phil

For this we studied the Bachelor of Natural Science offered by the Instituto Federal de Santa Catarina (SC-IF) - Campuses in San Jose / Installation chemistry (Case A) and Campi Araranguá / Installation Physics (Case B), the Starting in 2008, where teachers used "concept map" in the drafting of curriculum planning with the intention of making it "integrated". We assumed that despite a growing appreciation of the use of concept maps to organize core concepts of academic curricula discussions regarding curricular implications, Brazil and, more specifically, in education, are still scarce. In this sense, reflect on and proposals for curriculum integration within their historical constitution of curriculum studies, the history of thinking about educational curriculum based on the analysis of matrices of classical thought on curriculum and theoretical principles that underlie the cognitive work with the tool "conceptual map" in the organization of curricula and learning. The empirical research found that the use "concept map" has facilitated the construction and representation of the curriculum to promote better understanding and systematization of the ideas worked out by the group during planning. However the curriculum in action" is much more difficult to operationalize this integration of the original proposal or even view it / O presente estudo discute os limites e as possibilidades teórico-metodológicas de mapas conceituais como apoio à construção de currículos integrados para a aprendizagem das ciências. Para isso estudou-se o Curso de Licenciatura em Ciências da Natureza oferecido pelo Instituto Federal de Santa Catarina (IF-SC) no Campus São José/Habilitação Química (Caso A) e no Campus Araranguá/Habilitação Física (Caso B), a partir de 2008, onde os professores utilizaram a ferramenta cognitiva mapa conceitual no processo de elaboração do planejamento curricular com a intenção de torná-lo integrado . Partimos do pressuposto de que apesar de uma crescente valorização do uso de mapas conceituais para organizar os conceitos centrais dos currículos acadêmicos as discussões quanto às implicações curriculares, no Brasil e, mais especificamente, na área de educação, ainda são escassas. Neste sentido, refletimos sobre propostas de integração curricular e sua constituição histórica dentro dos estudos curriculares, a história do pensamento educacional sobre organização curricular a partir da análise das matrizes clássicas de pensamento sobre organização curricular e princípios teóricos que embasam o trabalho com mapas conceituais em organização de currículos e na aprendizagem. Na pesquisa empírica constatamos que o uso de mapas conceituais facilitou a construção e a representação da matriz curricular ao promover um melhor entendimento e sistematização das ideias trabalhadas pelo grupo durante o planejamento. No entanto no currículo em ação é muito mais difícil operacionalizar esta integração da proposta inicial ou mesmo visualizá-la

Mapas conceituais: tecnologia cognitiva para entendimento textual na educação de jovens e adultos

Amaral, Marco Antônio Franco do 04 March 2015 (has links)
This exploratory and experimental research aims to analyze the use of Concept Maps as a Cognitive Technology for textual understanding in adult education. The research was conducted with Youth and Adult elementary school students during Portuguese language classes. To achieve this goal, the pedagogical features implemented in the study context were observed and then they were applied in 28 lessons divided into 7 study units , for two groups of 15 students classified as Control and Experimental Groups. For the first group, the classes were taught following the traditional method which was seen in the initial observations. For the Experimental Group, a methodology based on the creation of Concept Maps was developed. The teaching methodology was theoretically grounded in studies on the Theory of Meaningful Learning, Concept Maps, Textual Coherence, and Discursive Textual Analysis. To analyze the evolution in the construction of Concept Maps and textual understanding, we used Student\'s t-test, the Discursive Textual Analysis proposed by Moraes and Galiazzi, and Wordle. The data analysis showed that the Experimental Group achieved a 30% increase in the conceptual framework with a fostering in the propositional meaningful learning when compared to the Control Group. This group was also more capable to turn declarative knowledge into procedural. The Conceptual Map proved, therefore, to be a Cognitive Technology effective for increasing textual understanding in the context of the search. / Esta pesquisa exploratória e experimental realizada na Educação de Jovens e Adultos, em turmas do Ensino Fundamental I na disciplina Língua Portuguesa, pretende contribuir para um estudo a fim da verificação da utilização dos Mapas Conceituais como uma Tecnologia Cognitiva para o entendimento textual na EJA. Para tal, foi realizada uma observação das características pedagógicas implementadas no contexto de estudo e, posteriormente, foram aplicadas em 28 aulas, divididas em 7 unidades de estudo, para dois grupos de 15 alunos classificados como Grupos Controle e Experimental. Para o primeiro grupo, foram ministradas as aulas conforme o modelo comumente verificado nas observações iniciais. Para o Grupo Experimental, foi desenvolvida uma proposta metodológica envolvendo a criação de Mapas Conceituais durante as unidades de estudo. A metodologia de ensino tem como fundamentação teórica os estudos sobre a Teoria da Aprendizagem Significativa, Mapas Conceituais, Coerência Textual e Análise Textual Discursiva. Como instrumentos de análise de dados da evolução na construção dos Mapas Conceituais e entendimento textual, foram utilizados o Teste t de Student, a Análise Textual Discursiva proposta por Moraes e Galiazzi e o Wordle. A análise das avaliações de entendimento textual e Mapas Conceituais produzidos demonstraram que o Grupo Experimental obteve um aumento de 30% no arcabouço conceitual com um favorecimento na aprendizagem significativa proposicional quando comparado ao Grupo Controle. Este grupo também se mostrou mais capaz na transformação do conhecimento declarativo em procedimental. O Mapa Conceitual se revelou, portanto, como uma Tecnologia Cognitiva eficaz para o aumento no entendimento textual no contexto da pesquisa. / Mestre em Tecnologias, Comunicação e Educação

The Use of a Computer Graphic Organizer for Persuasive Composition Writing by Hispanic Students with Specific Learning Disabilities

Unzueta, Caridad H 16 September 2009 (has links)
Many culturally and linguistically diverse (CLD) students with specific learning disabilities (SLD) struggle with the writing process. Particularly, they have difficulties developing and expanding ideas, organizing and elaborating sentences, and revising and editing their compositions (Graham, Harris, & Larsen, 2001; Myles, 2002). Computer graphic organizers offer a possible solution to assist them in their writing. This study investigated the effects of a computer graphic organizer on the persuasive writing compositions of Hispanic middle school students with SLD. A multiple baseline design across subjects was used to examine its effects on six dependent variables: number of arguments and supporting details, number and percentage of transferred arguments and supporting details, planning time, writing fluency, syntactical maturity (measured by T-units, the shortest grammatical sentence without fragments), and overall organization. Data were collected and analyzed throughout baseline and intervention. Participants were taught persuasive writing and the writing process prior to baseline. During baseline, participants were given a prompt and asked to use paper and pencil to plan their compositions. A computer was used for typing and editing. Intervention required participants to use a computer graphic organizer for planning and then a computer for typing and editing. The planning sheets and written composition were printed and analyzed daily along with the time each participant spent on planning. The use of computer graphic organizers had a positive effect on the planning and persuasive writing compositions. Increases were noted in the number of supporting details planned, percentage of supporting details transferred, planning time, writing fluency, syntactical maturity in number of T-units, and overall organization of the composition. Minimal to negligible increases were noted in the mean number of arguments planned and written. Varying effects were noted in the percent of transferred arguments and there was a decrease in the T-unit mean length. This study extends the limited literature on the effects of computer graphic organizers as a prewriting strategy for Hispanic students with SLD. In order to fully gauge the potential of this intervention, future research should investigate the use of different features of computer graphic organizer programs, its effects with other writing genres, and different populations.

Recherche et développement du Logiciel Intelligent de Cartographie Inversée, pour l’aide à la compréhension de texte par un public dyslexique / Research and development of the "Logiciel Intelligent de Cartographie Inversée", a tool to help dyslexics with reading comprehension.

Laurent, Mario 05 October 2017 (has links)
Les enfants souffrant de troubles du langage, comme la dyslexie, rencontrent de grandes difficultés dans l'apprentissage de la lecture et dans toute tâche de lecture, par la suite. Ces difficultés compromettent grandement l'accès au sens des textes auxquels ils sont confrontés durant leur scolarité, ce qui implique des difficultés d'apprentissage et les entraîne souvent vers une situation d'échec scolaire. Depuis une quinzaine d'années, des outils développés dans le domaine du Traitement Automatique des Langues sont détournés pour être utilisés comme stratégie d'aide et de compensation pour les élèves en difficultés. Parallèlement, l'usage de cartes conceptuelles ou de cartes heuristiques pour aider les enfants dyslexiques à formuler leurs pensées, ou à retenir certaines connaissances, s'est développé. Ce travail de thèse vise à répertorier et croiser, d'une part, les connaissances sur le public dyslexique, sa prise en charge et ses difficultés, d'autre part, les possibilités pédagogiques ouvertes par l'usage de cartes, et enfin, les technologies de résumé automatique et d'extraction de mots-clés. L'objectif est de réaliser un logiciel novateur capable de transformer automatiquement un texte donné en une carte, celle-ci doit faciliter la compréhension du texte tout en comprenant des fonctionnalités adaptées à un public d'adolescents dyslexiques. Ce projet a abouti, premièrement, à la réalisation d'une expérimentation exploratoire, sur l'aide à la compréhension de texte grâce aux cartes heuristiques, qui permet de définir de nouveaux axes de recherche ; deuxièmement, à la réalisation d'un prototype de logiciel de cartographie automatique qui est présenté en fin de thèse / Children with language impairment, such as dyslexia, are often faced with important difficulties when learning to read and during any subsequent reading tasks. These difficulties tend to compromise the understanding of the texts they must read during their time at school. This implies learning difficulties and may lead to academic failure. Over the past fifteen years, general tools developed in the field of Natural Language Processing have been transformed into specific tools for that help with and compensate for language impaired students' difficulties. At the same time, the use of concept maps or heuristic maps to encourage dyslexic children express their thoughts, or retain certain knowledge, has become popular. This thesis aims to identify and explore knowledge about the dyslexic public, how society takes care of them and what difficulties they face; the pedagogical possibilities opened up by the use of maps; and the opportunities created by automatic summarization and Information Retrieval fields. The aim of this doctoral research project was to create an innovative piece of software that automatically transforms a given text into a map. It was important that this piece of software facilitate reading comprehension while including functionalities that are adapted to dyslexic teenagers. The project involved carrying out an exploratory experiment on reading comprehension aid, thanks to heuristic maps, that make the identification of new research topics possible, and implementing an automatic mapping software prototype that is presented at the end of this thesis

Rôle d'un espace de travail numérique privé dans une activité d'édition collaborative de cartes conceptuelles : Cas d'étude en lycée / The role of a private digital workspace in a collaborative activity based on concept maps : Case study in high school / El rol de un espacio de trabajo digital privado en una actividad de edición colaborativa de mapas conceptuales : Estudio de caso en instituto

Gracia-Moreno, Carolina 11 December 2017 (has links)
L'utilisation des artefacts numériques pour la réalisation d'activités d'apprentissage reste le plus souvent individuelle, faute de disposer d'environnements adaptés, tant du point de vue du matériel que des applications et des pratiques pédagogiques. Cette recherche rend compte de l'expérience d'usages de différents artefacts dans une activité collaborative d'élaboration de cartes mentales et conceptuelles proposée en cours d'histoire de seconde. L'objectif principal est l'étude du rôle de l'espace de travail privé pour l'édition collective de cartes mentales et conceptuelles. Plus précisément, l'objectif est d'évaluer si le recours aux artefacts numériques lors de l'édition collective de cartes mentales et conceptuelles favorise les processus de confrontation cognitive constitutifs de la collaboration. Pour répondre à cet objectif, deux itérations (expérimentation pilote et expérimentation) ont été réalisées avec deux prototypes de dispositif numérique de collaboration qui permettent aux élèves de différencier leur espace de travail individuel de l'espace collectif. La première expérimentation pilote a été réalisée en 2015 avec un prototype de cartes mentales existant avant l'étude. Elle a consisté à valider le protocole expérimental de la recherche et à préciser les questions de recherche et les hypothèses. La deuxième expérimentation, quant à elle, a été réalisée au cours de l'année 2016 via un prototype de cartes conceptuelles conçu et développé dans le cadre de cette recherche. Cette expérimentation a eu pour but d'éprouver les trois hypothèses formulées, qui s'inscrivent dans la théorie de l'apprentissage social de Bandura (1980) et portent à la fois sur des déterminants environnementaux, cognitifs et comportementaux. La première hypothèse (déterminants environnementaux) suppose tout d'abord que la médiation instrumentale d'une activité d'apprentissage collaborative a une influence sur la participation des élèves. La deuxième hypothèse (déterminants cognitifs) quant à elle, soutient que l'adjonction d'un espace de travail personnel de l'élève à un espace d'interaction collectif favorise des processus cognitifs présents dans la collaboration : le conflit sociocognitif (Doise et Mugny, 1997; Perret-Clermont, 1979), l'étayage (Bruner, 1997) et la vicariance (Bandura, 1980; Pentland, 2015). Enfin, la troisième hypothèse (déterminants comportementaux) suggère que la participation individuelle des élèves sur l'élaboration d'une carte conceptuelle collective est influencée par la culture affective du groupe. Afin de vérifier ces 3 hypothèses, un plan expérimental multifactoriel croisé a été mis en place, ce qui a permis de tester les variables indépendantes simultanément auprès de 7 groupes de lycéens de seconde en classe d'histoire. L'analyse de données effectuée est centrée sur la nature des interactions orales et numériques des élèves, ainsi que sur leurs productions écrites et leurs réponses aux entretiens collectifs et aux questionnaires individuels. Les résultats montrent la tendance du dispositif numérique de collaboration (artefacts, organisation de l'activité, scénario pédagogique) à favoriser le processus d'étayage et vicariance suite aux échanges nécessaires à la coordination des tâches techniques d'édition de la carte conceptuelle. Les résultats indiquent qu'après l'utilisation d'un espace privé numérique, les élèves ont des conflits sociocognitifs significatifs lors du travail en groupe, les entraînant à accepter les réponses les plus ouvertes afin d'éviter la confrontation. / The use of digital artifacts for learning activities usually remains individual, as there are no suitable environments, from the point of view of materials, applications and teaching practices. This research reports on the experience of using different artefacts in a collaborative activity to elaborate mental and conceptual maps proposed in a history class in the eleventh grade. The aim is to study the role of a private workspace for the collective edition of mental and conceptual maps. More specifically, the goal is to assess whether the use of digital artifacts in the collective edition of mental and conceptual maps promotes the processes of cognitive confrontation that constitutes collaboration. To meet this objective, two iterations (pilot experimentation and experimentation) were carried out with two digital collaborative prototypes that allow students to differentiate their individual workspace from the collective space. The first pilot experiment was conducted in 2015 with a prototype of mental maps existing prior to the study. It consisted of validating the experimental protocol of the research and clarifying research questions and hypotheses. The second experiment, meanwhile, was carried out in 2016 via a prototype of concept maps designed and developed as part of this research. The purpose of this experiment was to test the three hypotheses formulated, which fit into Bandura's (1980) theory of social learning and address environmental, cognitive and behavioral determinants. The first hypothesis (environmental determinants) assumes that the instrumental mediation of a collaborative learning activity has an influence on the student participation. The second hypothesis (cognitive determinants), for its part, argues that the addition of a personal workspace of the student to a collective interaction space favors cognitive processes present in collaboration: sociocognitive conflict (Doise and Mugny Perret-Clermont, 1979), supporting (Bruner, 1997) and vicariance (Bandura, 1980, Pentland, 2015). Finally, the third hypothesis (behavioral determinants) suggests that the individual participation of pupils in the elaboration of a collective concept map is influenced by the affective culture of the group. In order to verify these 3 hypotheses, a crossed multifactorial experimental plan was put in place, which made it possible to test the independent variables simultaneously with 7 groups of high school students in history class. The data analysis carried out focuses on the nature of students' oral and digital interactions, as well as their written outputs and their responses to group interviews and individual questionnaires. The results show the trend of the digital collaboration device (artifacts, organization of the activity, pedagogical scenario) to favor the supporting and vicariance process as an explanation of the exchanges needed to coordinate the technical tasks of editing the concept map. The results indicate that after using a digital private space, pupils have significant sociocognitive conflicts during group work, leading them to accept the most open responses in order to avoid confrontation. / El uso de artefactos digitales para la realización de actividades de aprendizaje sigue siendo principalmente individual, por falta de entornos adecuados, desde el punto de vista del material, de las aplicaciones y de las prácticas pedagógicas. Esta investigación cuenta la experiencia de uso de diferentes artefactos en una actividad colaborativa de elaboración de mapas mentales y conceptuales propuestos en el transcurso de una clase de historia de cuarto de educación secundaria. El objetivo principal es el estudio del rol del espacio de trabajo privado para la edición colectiva de mapas mentales y conceptuales. Más específicamente, el objetivo es evaluar si el uso de artefactos digitales en la edición colectiva de mapas mentales y conceptuales promueve los procesos de confrontación cognitiva que constituyen la colaboración. Para cumplir este objetivo, se realizaron dos iteraciones (experimentación piloto y experimentación) con dos prototipos de dispositivos digitales colaborativos que permiten a los estudiantes diferenciar su espacio de trabajo individual del espacio colectivo. El primer experimento piloto se llevó a cabo en 2015 con un prototipo de mapas mentales existente antes del estudio. Consistió en validar el protocolo experimental de la investigación y aclarar preguntas e hipótesis de investigación. El segundo experimento, mientras tanto, se llevó a cabo en 2016 a través de un prototipo de mapas conceptuales diseñados y desarrollados como parte de esta investigación. Este experimento fue diseñado para verificar las tres hipótesis formuladas, que se ajustan a la teoría del aprendizaje social de Bandura (1980) y abordan los determinantes ambientales, cognitivos y conductuales. La primera hipótesis (determinantes ambientales) supone que la mediación instrumental de una actividad de aprendizaje colaborativo influye en la participación del alumno. La segunda hipótesis (determinantes cognitivos), por su parte, sostiene que la adición de un espacio de trabajo personal del alumno a un espacio de interacción colectivo promueve procesos cognitivos presentes en la colaboración: el conflicto socio-cognitivo (Doise y Mugny Perret-Clermont, 1979), el apoyo (Bruner, 1997) y la vicarianza (Bandura, 1980, Pentland, 2015). Finalmente, la tercera hipótesis (determinantes conductuales) sugiere que la participación individual de los alumnos en la elaboración de un mapa conceptual colectivo está influenciada por la cultura afectiva del grupo. Para verificar estas 3 hipótesis, se puso en marcha un plan experimental multifactorial cruzado, que permitió probar las variables independientes simultáneamente con 7 grupos de estudiantes de cuarto de secundaria en la clase de historia. El análisis de datos realizado se centra en la naturaleza de las interacciones orales y digitales de los estudiantes, así como en sus resultados escritos y sus respuestas a entrevistas grupales y cuestionarios individuales. Los resultados muestran la tendencia de los dispositivos digitales de colaboración (artefactos, la organización de la actividad, escenario pedagógico) a promover el proceso de apoyo y vicariedad tras las conversaciones necesarias para coordinar las acciones técnicas para publicar en el mapa conceptual. Los resultados indican que después de usar un espacio privado digital, los estudiantes tienen conflictos sociocognitivos significativos durante el trabajo en grupo, lo que los lleva a aceptar las respuestas más abiertas para evitar el enfrentamiento.
