Muito embora o golpe civil e militar de 1964 houvesse instaurado no país, principalmente entre as fileiras progressistas dos campos político, intelectual e artístico, um clima de tensão permanente, alguns setores da produção cultural pernambucana destacaram-se por sua articulação e resistência no período pós-golpe. Através do protagonismo artístico dos Grupos Construção e Raiz, entre os anos 1965 e 1967, com a realização de shows-pesquisas, festivais de bossa nova, feiras regionais de música, programas musicais de televisão bem como cursos acadêmicos foi possível reintroduzir no cenário cultural local a discussão sobre a atualização da identidade nordestina a partir dos discursos da modernidade. A agitação cultural promovida por tais grupos, no entanto, seria radicalizada pelo professor universitário e ensaísta Jomard Muniz de Britto e outros artistas e intelectuais a partir de 1968. Oriundos do mesmo grupo de sociabilidade que havia construído as ideias e práticas culminantes tanto do Construção quanto do Raiz, acrescidos posteriormente de alguns integrantes do Grupo Sanhauá bem como do Poema-Processo, os tropicalistas promoveram uma verdadeira carnavalização artístico-intelectual entre as cidades de Recife e Olinda. Sob a égide da antropofagia oswaldiana, agenciada àquela altura pela vanguarda artística brasileira, os tropicalistas pernambucanos visualizaram no coro da marginalidade o caminho ideal para promoção da desprovincianização da cultura nordestina. / The tessitura of this work consists of a historical narrative about the installation of the Tropicalia forefront in Pernambuco cultural field specifically between the years 1967 and 1968. Although the civil and military coup of 1964 were introduced in the country, especially among the ranks of progressive political, intellectual and artistic, a climate of permanent tension, some sectors of Pernambuco cultural production stood out for its articulation and resistance in the post-coup period. Through the artistic leadership of Group Construction and Root, between the years 1965 and 1967, with the realization of shows, research, bossa nova festivals, regional music shows, musical programs television as well academic courses was possible to reintroduce the local cultural scene discussion on updating the northeastern identity from the discourse of modernity. The cultural agitation by such groups, however, would be radicalized by university professor and essayist Jomard Muniz de Britto and other artists and intellectuals from 1968. Coming from the same group of sociability that had built the ideas and practices culminating both construction as root later augmented by members of Sanhauá Group and the Poem-Process, the tropicalists promoted a true artistic and intellectual carnivalization between the cities of Recife and Olinda. Under the aegis of Oswaldian cannibalism, brokered by then the Brazilian artistic avant-garde, Pernambucans tropicalistas viewed the chorus of marginality the ideal way to promote deprovincialization of northeastern culture.

The thesis deals with the process of construction of mathematical knowledge of an individual and a group of pupils. At the outset, some concepts are discussed which belong to the theoretical background of our research (knowledge construction process and its mechanism, typology of mathematical knowledge, character of a mathematical structure, constructivist approaches to the teaching of mathematics, creative teaching, action research). Some results of selected local and foreign research focusing on constructivist approaches and action research in mathematics education are given. The methodology mainly consists of teaching experiments which can, to a certain extent, be seen as cycles of cooperative action research. The target group consists of pupils of lower secondary grammar school. The data gathered through traditional methods of qualitative research (participation observation, audio and videorecordings, pupils' artefacts, notes of an external observer, etc.) were analysed using the techniques of grounded theory. The research has generated results of three types: (1) The categories of individual and group constructions in mathematics have been described in depth including their dimensions (the measures of the teacher's influence on the construction, of the pupils' cooperation, of pupils' formal acceptance...
