O diário gráfico como estratégia de aprendizagem em busca da autonomia : um estudo de caso com alunos do 7º e 8º ano

Orientação: Inês Maria Andrade MarquesO presente estudo explora o diário gráfico como ferramenta pedagógica no ensino das artes visuais, no âmbito da disciplina de Educação Visual, levando em conta o pensamento de vários autores que se dedicaram a temas da educação artística, à importância das artes, ao desenvolvimento do adolescente, ao desenho e ao objeto desta investigação: o diário gráfico. O estudo empírico desta dissertação visa aclarar as potencialidades do diário gráfico em contexto de sala de aula e fora desta. Tem por objetivos testar o diário gráfico enquanto meio para aumentar a autonomia dos alunos na escolha dos temas e na gestão da assiduidade dos registos gráficos, bem como meio para desenvolver qualidades técnicas e expressivas dos seus desenhos. A presente pesquisa foi desenvolvida com duas turmas de 7º e 8ºAno na disciplina de Educação Visual, com base na unidade didática – Diário Gráfico. Esta unidade teve como objetivo explorar vários métodos e técnicas, com o intuito de promover o progresso dos trabalhos dos alunos. A análise dos dados revela que as práticas pedagógicas em causa contribuem para um melhoramento do desempenho dos alunos ao nível das suas competências, no que diz respeito á autorregulação dos seus trabalhos. Pretende-se que a abordagem do diário gráfico num ponto de vista pedagógicodidático, constitua um contributo para o enriquecimento da disciplina de Educação Visual, bem como para a melhoria das práticas e métodos dos professores que a lecionem.The present study explores the graphic diary as a pedagogical tool in visual arts teaching within the scope of the Visual Education discipline, taking into account the thinking of several authors who have dedicated themselves to themes of artistic education, to the importance of the arts, to the development of the adolescent, to the drawing and object of this investigation: the graphic diary. The empirical study of this dissertation aims at clarifying the potentialities of the graphic diary inside and outside the classroom context. The intention is to verify the graphic diary at the level of the technical and expressive quality, as well as the level of autonomy, that the student can present in the choices of the subjects and in the management of the attendance of the graphic registers. The present research was developed based on two classes of 7th and 8th year in the discipline of Visual Education, based on didactic unit – Graphic Diary. This unit aimed to explore various methods and techniques, in order to promote the progress of students' work. The analysis of the data shows that the pedagogical practices in question contribute to an improvement in the performance of pupils at the level of their competences, as regards self-regulation of their work. It is intended that the approach of the graphic journal in a pedagogical-didactic point of view, constitutes a contribution to the enrichment of the Visual Education discipline, as well as to the improvement of the practices and methods of the teachers who teach it

Intramembranous Bone Healing Process Subsequent to Tooth Extraction in Mice: Micro-Computed Tomography, Histomorphometric and Molecular Characterization

<div><p>Bone tissue has a significant potential for healing, which involves a significant the interplay between bone and immune cells. While fracture healing represents a useful model to investigate endochondral bone healing, intramembranous bone healing models are yet to be developed and characterized. In this study, a micro-computed tomography, histomorphometric and molecular (RealTimePCRarray) characterization of post tooth-extraction alveolar bone healing was performed on C57Bl/6 WT mice. After the initial clot dominance (0h), the development of a provisional immature granulation tissue is evident (7d), characterized by marked cell proliferation, angiogenesis and inflammatory cells infiltration; associated with peaks of growth factors (BMP-2-4-7,TGFβ1,VEGFa), cytokines (TNFα, IL-10), chemokines & receptors (CXCL12, CCL25, CCR5, CXCR4), matrix (Col1a1-2, ITGA4, VTN, MMP1a) and MSCs (CD105, CD106, OCT4, NANOG, CD34, CD146) markers expression. Granulation tissue is sequentially replaced by more mature connective tissue (14d), characterized by inflammatory infiltrate reduction along the increased bone formation, marked expression of matrix remodeling enzymes (MMP-2-9), bone formation/maturation (RUNX2, ALP, DMP1, PHEX, SOST) markers, and chemokines & receptors associated with healing (CCL2, CCL17, CCR2). No evidences of cartilage cells or tissue were observed, strengthening the intramembranous nature of bone healing. Bone microarchitecture analysis supports the evolving healing, with total tissue and bone volumes as trabecular number and thickness showing a progressive increase over time. The extraction socket healing process is considered complete (21d) when the dental socket is filled by trabeculae bone with well-defined medullary canals; it being the expression of mature bone markers prevalent at this period. Our data confirms the intramembranous bone healing nature of the model used, revealing parallels between the gene expression profile and the histomorphometric events and the potential participation of MCSs and immune cells in the healing process, supporting the forthcoming application of the model for the better understanding of the bone healing process.</p></div

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions forecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosys-tem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts withdomestic dogs, these species have been threatened locally, regionally, or even across their fulldistribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths.Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae(3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data onDasypus pilo-sus(Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized,but new genetic studies have revealed that the group is represented by seven species. In thisdata paper, we compiled a total of 42,528 records of 31 species, represented by occurrence andquantitative data, totaling 24,847 unique georeferenced records. The geographic range is fromthe southern United States, Mexico, and Caribbean countries at the northern portion of theNeotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regardinganteaters,Myrmecophaga tridactylahas the most records (n=5,941), andCyclopessp. havethe fewest (n=240). The armadillo species with the most data isDasypus novemcinctus(n=11,588), and the fewest data are recorded forCalyptophractus retusus(n=33). Withregard to sloth species,Bradypus variegatushas the most records (n=962), andBradypus pyg-maeushas the fewest (n=12). Our main objective with Neotropical Xenarthrans is to makeoccurrence and quantitative data available to facilitate more ecological research, particularly ifwe integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, andNeotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure,habitat loss, fragmentation effects, species invasion, and climate change effects will be possiblewith the Neotropical Xenarthrans data set.
