Prática de ensino supervisionada em educação pré-escolar e ensino do 1º ciclo do ensino básico: a articulação integrada do saber

O presente relatório desenvolve-se no âmbito da unidade curricular de Prática de Ensino Supervisionada para obter o grau mestre em Educação Pré-escolar e Ensino do 1º Ciclo do Ensino Básico apresentando o trabalho de investigação-ação desenvolvido em contexto de Jardim de Infância e 1º Ciclo do Ensino Básico focalizado na articulação integrada do saber. Elegeram-se como objetivos deste trabalho compreender a natureza das aprendizagens nas primeiras idades, promovendo a construção articulada do saber evitando a sua disciplinarização, utilizando diversas linguagens e implementar a metodologia de projeto no trabalho curricular. O enquadramento teórico procura aprofundar conceitos de interdisciplinaridade e construção articulada do saber nos processos de aprendizagem e o trabalho de projeto enquanto matriz de construção de conhecimento. Sustentado na metodologia de investigaçãoação utilizaram-se diversos instrumentos de recolha e análise de dados como a observação, registo de notas de campo e entrevistas às crianças permitindo responder aos objetivos delineados. Este trabalho permitiu compreender a necessidade da construção articulada das aprendizagens para promover aprendizagens significativas; Supervised teaching Practice in Pre-school and Primary Education: Integrated Knowledge Construction Abstract: This is the report of the action-research project developed in the context of a Pre-school and a Primary School focused on the integration of knowledge, part of the curricular unit Supervised Teaching Practice of the Master in Pre-school Education and Teaching in Basic Education (1st cycle). The objectives of this work are: to understand the nature of learning in the early ages through not only promoting the construction of an articulated knowledge while avoiding its disciplinarization, but also using several languages and implement the project methodology in curricular work. The theoretical framework seeks to explore the concepts of interdisciplinarity and the integration of knowledge’s construction in the processes of learning as the project’s work as a basic framework of knowledge construction. Adopting an action-research methodology, several instruments were used for data collection and analysis, such as observation, field notes and interviews to children, allowing to reach the stipulated objectives. This study provided the understanding of the need for the learning’s articulated creation to promote relevant learning.

Mechanical properties of adobe blocks used in building construction in Huambo Province - Angola

Despite significant advances in building technologies with the use of conventional construction materials (as concrete and steel), which significantly have driven the construction industry, earth construction have demonstrated its importance and relevance, as well as it has matched in an efficient and eco-friendly manner the social housing concerns. The diversity of earth construction techniques allowed this material to adapt to different climatic, cultural and social contexts until the present time. However, in Angola, the construction with earth is still associated with population fringes of weak economic resources, for which, given the impossibility of being able to acquire modern construction materials (steel, cement, brick, among others), they resort to the use of available natural materials. Furthermore, the lack of scientific and technical knowledge justifies the negative appreciation of traditional building techniques, and the derogatory way how are considered the earth constructions in Angolan territory. Given the country's current development status, and taking into account the environmental requirements and the real socio-economic sustainability of Angola, it is considered that one of the viable and adequate options, could be the recovering and upgrading of the ancestral techniques of earth construction. The purpose of this research is to develop the technical and scientific knowledge in order to improve and optimize these construction solutions, responding to the real problems of housing quality as well as to the current social, economic and environmental sustainability requirements. In this paper, a description of the physical and mechanical characteristics of the adobes typically used in the construction of traditional houses in some localities of Huambo, province in Angola, is carried out. The methodology was based on mechanical in-situ testing in adobe blocks manufactured with traditional procedures: i) tensile strength evaluated with the bending test and compressive strength test on earth blocks specimens; and, ii) durability and erodibility test by Geelong method adopting the New Zealand standard (NZS) procedures (4297: 1998; 4297: 1998 and 4297: 1999). The results allow the characterization of the materials used in the construction of raw earth in the Huambo region, contributing to the development of knowledge of these sustainable and traditional housing constructive solutions with a strong presence in Angola [1, 2]. This study is part of a larger project in the area of Earth Construction [3], which aims to produce knowledge which can stimulate the use of environmental friendly construction materials and contribute to develop constructive solutions with improved performance, durability, comfort, safety and sustainability.
