Becoming to Know: Essays on Extended Epistemology of Knowledge Creation

This qualitative, explorative study, which comprises four essays, focuses on knowledge management (KM). It seeks to answer the question: How can the knowledge creation theory of KM benefit from social learning theories? While studying the five development phases of knowledge creation theory of KM through 1995-2008 and applying some social learning theories in essays, the concepts of knowing, learning and becoming have emerged. Drawing on these three concepts and on becoming ontology and extended epistemology as research philosophies the study suggests the ‘becoming epistemology’ concept and develops the ‘becoming to know’ framework. The framework proposes becoming as phronesis of dialectic interactions between learning and knowing. It shows how becoming to know evolves as an interplay between concrete experience and logical thinking in the present and in a living context. The proposed framework could be considered a contribution to the current development phase of the knowledge creation theory of KM because it illustrates how ontological and epistemological knowledge spirals come together, which is the essence of the knowledge creation theory of KM.

Impact of the intrinsic motivation on the academic performance through voluntary assignments: An empirical analysis

The students academic performance is a key aspect for all agents involved in a higher education quality program. However, there is no unanimity on how to measure it. Some professionals choose assessing only cognitive aspects while others lean towards assessing the acquisition of certain skills. The need to train increasingly adapted professionals in order to respond to the companies’ demands and being able to compete internationally in a global labour market requires a kind of training that goes beyond memorizing. Critical and logical thinking are amongst written language skills demanded in the field of Social Sciences. The objective of this study is to empirically demonstrate the impact of voluntary assignments on the academic performance of students. Our hypothesis is that students who complete high quality voluntary assignments are those more motivated and, therefore, those with higher grades. An experiment with students from the "Financial Accounting II" during the academic year of 2012/13 at the Business and Economics School of the UCM was carried out. A series of voluntary assessments involving the preparation of accounting essays were proposed in order to develop skills and competencies as a complement to the lessons included in the curriculum of the subject. At the end of the course, the carrying-out or not of the essay together with its critical, reflective quality and style, were compared. Our findings show a relationship between the voluntarily presented papers of quality and the final grade obtained throughout the course. These results show that the students intrinsic motivation is a key element in their academic performance. On the other hand, the teachers role focuses on being a motivating element through the learning process.

La cohérence conceptuelle d’étudiants collégiaux en mécanique newtonienne et en métrologie

Cette thèse porte sur l’évaluation de la cohérence du réseau conceptuel démontré par des étudiants de niveau collégial inscrits en sciences de la nature. L’évaluation de cette cohérence s’est basée sur l’analyse des tableaux de Burt issus des réponses à des questionnaires à choix multiples, sur l’étude détaillée des indices de discrimination spécifique qui seront décrits plus en détail dans le corps de l’ouvrage et sur l’analyse de séquences vidéos d’étudiants effectuant une expérimentation en contexte réel. Au terme de ce projet, quatre grands axes de recherche ont été exploré. 1) Quelle est la cohérence conceptuelle démontrée en physique newtonienne ? 2) Est-ce que la maîtrise du calcul d’incertitude est corrélée au développement de la pensée logique ou à la maîtrise des mathématiques ? 3) Quelle est la cohérence conceptuelle démontrée dans la quantification de l’incertitude expérimentale ? 4) Quelles sont les procédures concrètement mise en place par des étudiants pour quantifier l’incertitude expérimentale dans un contexte de laboratoire semi-dirigé ? Les principales conclusions qui ressortent pour chacun des axes peuvent se formuler ainsi. 1) Les conceptions erronées les plus répandues ne sont pas solidement ancrées dans un réseau conceptuel rigide. Par exemple, un étudiant réussissant une question sur la troisième loi de Newton (sujet le moins bien réussi du Force Concept Inventory) montre une probabilité à peine supérieure de réussir une autre question sur ce même sujet que les autres participants. De nombreux couples de questions révèlent un indice de discrimination spécifique négatif indiquant une faible cohérence conceptuelle en prétest et une cohérence conceptuelle légèrement améliorée en post-test. 2) Si une petite proportion des étudiants ont montré des carences marquées pour les questions reliées au contrôle des variables et à celles traitant de la relation entre la forme graphique de données expérimentales et un modèle mathématique, la majorité des étudiants peuvent être considérés comme maîtrisant adéquatement ces deux sujets. Toutefois, presque tous les étudiants démontrent une absence de maîtrise des principes sous-jacent à la quantification de l’incertitude expérimentale et de la propagation des incertitudes (ci-après appelé métrologie). Aucune corrélation statistiquement significative n’a été observée entre ces trois domaines, laissant entendre qu’il s’agit d’habiletés cognitives largement indépendantes. Le tableau de Burt a pu mettre en lumière une plus grande cohérence conceptuelle entre les questions de contrôle des variables que n’aurait pu le laisser supposer la matrice des coefficients de corrélation de Pearson. En métrologie, des questions équivalentes n’ont pas fait ressortir une cohérence conceptuelle clairement démontrée. 3) L’analyse d’un questionnaire entièrement dédié à la métrologie laisse entrevoir des conceptions erronées issues des apprentissages effectués dans les cours antérieurs (obstacles didactiques), des conceptions erronées basées sur des modèles intuitifs et une absence de compréhension globale des concepts métrologiques bien que certains concepts paraissent en voie d’acquisition. 4) Lorsque les étudiants sont laissés à eux-mêmes, les mêmes difficultés identifiées par l’analyse du questionnaire du point 3) reviennent ce qui corrobore les résultats obtenus. Cependant, nous avons pu observer d’autres comportements reliés à la mesure en laboratoire qui n’auraient pas pu être évalués par le questionnaire à choix multiples. Des entretiens d’explicitations tenus immédiatement après chaque séance ont permis aux participants de détailler certains aspects de leur méthodologie métrologique, notamment, l’emploi de procédures de répétitions de mesures expérimentales, leurs stratégies pour quantifier l’incertitude et les raisons sous-tendant l’estimation numérique des incertitudes de lecture. L’emploi des algorithmes de propagation des incertitudes a été adéquat dans l’ensemble. De nombreuses conceptions erronées en métrologie semblent résister fortement à l’apprentissage. Notons, entre autres, l’assignation de la résolution d’un appareil de mesure à affichage numérique comme valeur de l’incertitude et l’absence de procédures d’empilement pour diminuer l’incertitude. La conception que la précision d’une valeur numérique ne peut être inférieure à la tolérance d’un appareil semble fermement ancrée.

A questão do meio na pedologia e suas implicações pedagógicas

Ce texte est une lecture de la conférence de Vygotsky sur la question de l'influence de la culture et de l'environnement sur la pédologie et cherche les implications pédagogiques des ces idées sur l'éducation des enfants et, en particulier, les petits enfants. Initialement, met en évidence la méthode de l'auteur que enseigne à ses auditeurs et lecteurs à penser dialectiquement, un défi que doit être confrontés par les lecteurs - habitués à penser avec la logique formelle - pour essayer de comprendre les études de Vygotsky. Deux éléments apportés par Vygotsky à la conférence sont prise pour réfléchir sur son importance pour le développement de l'enfant: la question de la langue orale et de son importance pour l'influence de la culture et de l'environnement sur le développement humain dans l'enfance et la spécificité du développement culturel dans l'enfance que dit que ce que nous pouvons parvenir à la fin ou à la suite du processus de développement est présente dans la culture depuis le début et touche et guide ce développement de l'enfant. Dans les deux cas, la discussion au sein de cette conférence de Vygotsky déclenche une révolution dans la pensée et l'action des enseignants.

A criança indígena nos estudos acadêmicos no Brasil: uma análise das produções científicas (2001 – 2012)

O presente trabalho versa sobre as Concepções de Infância Indígena presentes em estudos acadêmicos produzidos no Brasil. Para os aportes deste estudo, considerou-se como questão norteadora: quais as concepções de Infância para as diversas etnias indígenas nas produções acadêmicas no Brasil no período de 2001 a 2012? O objetivo geral consistiu em investigar as concepções de infância para as diversas etnias indígenas presentes nas produções acadêmicas no Brasil no período de 2001 a 2012, visando (1) identificar e mapear essas concepções de infância indígena nas diversas etnias presentes nas produções acadêmicas; (2) descrever o processo de educação da criança indígena nas diversas etnias indígena brasileira; (3) abordar as práticas culturais da infância indígena mencionadas nesses estudos; (4) discutir a relevância, avanços e limites desses estudos para a compreensão da infância indígena no Brasil. O caminho metodológico percorrido para o desenvolvimento deste estudo foi de caráter bibliográfico tendo como fonte Dissertações e Teses coletadas no portal da CAPES no período de 2001 a 2012 sobre a infância indígena. Para efeito de sistematização do corpus de análise desse estudo e facilitar a compreensão do material, as dissertações e teses foram organizadas em três eixos temáticos: (1) Concepção étnica de infância indígena; (2) Práticas culturais da infância indígena; (3) Educação indígena. A partir da escolha dos eixos temáticos, pensou-se em categorias que pudessem facilitar o entendimento da metodologia escolhida para essa dissertação. Então foi escolhida para cada eixo temático uma categoria, a saber: (1) Liberdade; (2) Brincadeiras; (3) Educação indígena (escolar e tradicional). No que tange às categorias, foi possível perceber quão importante foi mencioná-las neste estudo, pois entendê-las nos permitiu também trazer à tona o rico arsenal que emergem ao estudar as concepções de infância ligadas à liberdade, à brincadeira e à educação. Tais concepções nos permitiu ter um novo olhar a respeito da infância nas sociedades indígenas, a partir de avanços/limites. Os resultados mostraram também que os estudos sobre a infância e/ou a criança indígena é incipiente, principalmente no estado do Pará e isso se deve ao fato de que os pesquisadores locais ainda não despertaram o interesse pela temática em questão, sendo possível elencar algumas razões para esse “não interesse”: falta de motivação de pesquisadores nessa área, a inserção desses estudos em várias áreas do conhecimento que não necessariamente no campo da educação e o difícil acesso as comunidades. Percebeu-se também que as produções realizadas em nossa região sobre a temática infância indígena são computadas no local de origem dos pesquisadores que para cá vêm realizar seus estudos deixando a região Norte no limite das produções sobre infância indígena. Ademais, urge a necessidade de investigar a infância e/ou a criança que vivem nas mais diversas sociedades indígenas. Eis aí um grande desafio e intento a ser superado para a compreensão do universo infantil e suas lógicas de pensar a realidade, o aprendizado, como sujeito complexo e pleno, de modo que suas percepções do cotidiano da aldeia, da escola, da família, dos rituais e dos símbolos constituam-se em tarefa de suma importância.

O ensino de informática para crianças: um estímulo à aprendizagem

The use of computers in childhood education makes it possible for them to acquire knowledge in a fun way through games. This paper describes the experience of implementing the course “Computers for Children”, which is part of a University Extension Program at the School of Dentistry at UNESP - Araraquara. This course is offered to children aged 5-7 years old and it aims, not only, to offer children, via computer, a direct contact with new teaching technologies, but also, to help them develop both their motor and logical thinking abilities through educational games. The children that participated in this course are from the Children’s Center “Casinha de Abelha” at the UNESP -Araraquara and also from the Municipal Recreation and Educational Centers also in Araraquara, SP, Brazil. The software resources used in this course to teach computer skills are the educational games “Coelho Sabido Maternal”, “A Estrela Cintilante” and “Festa dos Dentinhos”. The children’s learning and the level of difficulty in using the computer as a tool were evaluated. It was possible to conclude that the course has been contributing to the digital inclusion of children aged 5-7 years old, in addition to training their visual and audio perception, their motor coordination and memorization, hence developing skills that are essential to the children’s literacy process.

O Raciocínio lógico-matemático: classificação e uso em concursos públicos

This study offers an analysis of classification of the main issues of logic and logical thinking found in competitive tendering and math tests, according to their concepts and characteristics, whether involving mathematics, or not. Moreover, a research on the evolutionary historic processes of logic according to three major crises of the foundations of mathematics was conducted. This research helped to define Logic as a science that is quite distinctive from Mathematics. In order to relate the logical and the mathematical thinking, three types of knowledge, according to Piaget, were presented, with the logical-mathematical one being among them. The study also includes an insight on the basic concepts of propositional and predicative logic, which aids in the classification of issues of logical thinking, formal logic or related to algebraic, and geometric or arithmetic knowledge, according to the Venn diagrams. Furthermore, the key problems - that are most frequently found in tests are resolved and classified, as it was previously described. As a result, the classification in question was created and exemplified with eighteen logic problems, duly solved and explained

Effects of using manipulative materials to teach remedial algebra to community college students on achievement and attitudes towards mathematics

This dissertation derived hypotheses from the theories of Piaget, Bruner and Dienes regarding the effects of using Algebra Tiles and other manipulative materials to teach remedial algebra to community college students. The dependent variables measured were achievement and attitude towards mathematics. The Piagetian cognitive level of the students in the study was measured and used as a concomitant factor in the study.^ The population for the study was comprised of remedial algebra students at a large urban community college. The sample for the study consisted of 253 students enrolled in 10 sections of remedial algebra at three of the six campuses of the college. Pretests included administration of an achievement pre-measure, Aiken's Mathematics Attitude Inventory (MAI), and the Group Assessment of Logical Thinking (GALT). Posttest measures included a course final exam and a second administration of the MAI.^ The results of the GALT test revealed that 161 students (63.6%) were concrete operational, 65 (25.7%) were transitional, and 27 (10.7%) were formal operational. For the purpose of analyzing the data, the transitional and formal operational students were grouped together.^ Univariate factorial analyses of covariance ($\alpha$ =.05) were performed on the posttest of achievement (covariate = achievement pretest) and the MAI posttest (covariate = MAI pretest). The factors used in the analysis were method of teaching (manipulative vs. traditional) and cognitive level (concrete operational vs. transitional/formal operational).^ The analyses for achievement revealed a significant difference in favor of the manipulatives groups in the computations by campus. Significant differences were not noted in the analysis by individual instructors.^ The results for attitude towards mathematics showed a significant difference in favor of the manipulatives groups for the college-wide analysis and for one campus. The analysis by individual instructor was not significant. In addition, the college-wide analysis was significant in favor of the transitional/formal operational stage of cognitive development. However, support for this conclusion was not obtained in the analyses by campus or individual instructor. ^

O estrategista em perspectiva: um estudo sobre o processo de formação de estratégias no ramo varejista de construção civil de Natal e região metropolitana

The strategy research have been widespread for many years and, more recently, the process of formation of the strategies in the individual perspective has also gained attention in academia. Confirming this trend, the goal of this study is to discuss the process of formation of the strategies from an individual perspective based on the three dimensions of the strategic process (change, thinking and formation) proposed by De Wit and Meyer (2004). To this end, this exploratory-descriptive study used the factor analysis techniques, non-parametric correlation and linear regression to analyze data collected from the decision makers of the 93 retail in the industry of construction supplies in the Natal and metropolitan area. As a result, we have that the formation factors of the dimensions investigated were identified in the majority, thus confirming the existence of paradoxes in the strategic process, and that there is a relationship between logical thinking and deliberate formation with the hierarchical level of decision makers.

O ensino e aprendizagem da programação de computadores no ensino a distância : uma proposta de instanciação do modelo pedagógico virtual da Universidade Aberta

Hoje em dia o ensino e aprendizagem a distância online de nível universitário é, em grande medida, baseado em estratégias de aprendizagem colaborativa, onde, além de aprender sozinho, os estudantes também participam de ações colaborativas dentro de uma classe virtual. O nível de interação do estudante online representa um fator fundamental para o sucesso do processo de ensino-aprendizagem pois é a base da partilha de informação e construção do conhecimento entre estudantes e professores, enquanto todas as ações e atividades integram um modelo pedagógico comum. Existem muitas diferenças e desafios nas áreas de ensino em termos de instanciação do modelo pedagógico e adoção das estratégias de ensino-aprendizagem, como por exemplo, entre as áreas das ciências sociais e das engenharias. Uma área que atrai especial atenção como um todo é a das ciências da computação (CS), e de forma específica, a da programação de computadores. A programação de computadores exige, em primeiro lugar, o desenvolvimento de um bom raciocínio lógico e uma estratégia de resolução segundo uma abordagem “dividir para conquistar”, onde os principais problemas são divididos em problemas menores que são resolvidos individualmente. A programação exige também uma combinação entre o trabalho individual e em grupo, com elevados níveis de revisão e depuração do código fonte em desenvolvimento. O ensino online de programação de computadores é constituído por estes aspectos, exigindo um elevado grau de interação entre estudantes e entre estudantes e professor. Neste capítulo, vamos discutir e apresentar a nossa experiência no ensino online da programação de computadores com base no modelo pedagógico virtual da Universidade Aberta, e propor a sua instanciação e extensão específica para incluir novas estratégias de aprendizagem colaborativa e uma abordagem construtivista para o processo global de aprendizagem.

Enseñanza de la multiplicación desde un enfoque constructivista en tercero y cuarto año de Educación General Básica

La presente investigación tiene como objetivo demostrar teóricamente la importancia de la enseñanza de la multiplicación a partir de un enfoque constructivista en el tercero y cuarto año de Educación General Básica, años en los que esta enseñanza se profundiza. En efecto, este trabajo monográfico busca responder a las siguientes interrogantes: ¿En qué consiste la multiplicación y su proceso? ¿Cuál es la diferencia de enseñar la multiplicación desde un enfoque tradicional y un enfoque constructivo? Según la Actualización y Fortalecimiento Curricular (2010): ¿Cómo se debe desarrollar su proceso de enseñanza? ¿Qué estrategias se pueden utilizar para trabajar en la comprensión de la multiplicación en el tercero y cuarto año de Educación General Básica? Para responder estas preguntas se recurre a la revisión de información bibliográfica procedente de revistas, libros y artículos de diferentes autores, que facilitan cumplir con los objetivos planteados. Finalmente, se concluye que la enseñanza - aprendizaje basada en los lineamientos del enfoque pedagógico constructivista tiene como resultado la comprensión que los estudiantes necesitan tener hacia la multiplicación para poder utilizarla en su vida académica y cotidiana. Por tal razón se afirma que, la importancia de enseñar la multiplicación desde un enfoque constructivista se fundamenta en que este lineamiento pedagógico propende el uso de dicha operación matemática en la resolución de problemas, desarrollando así su pensamiento lógico – matemático y el razonamiento, a diferencia de lo que ocurre con el tradicionalismo en el que se memoriza por corto plazo.
