Ensino de língua inglesa para pré-escolares: apontamentos a partir de um processo de observação.
Trabalho de Conclusão do Curso de Especialização em Educação Infantil - primeira Edição – Polo Chapecó, para a obtenção do Grau de Especialista em Educação Infantil.Este artigo procura fazer alguns apontamentos acerca de como é desenvolvido o ensino de língua inglesa em uma turma de pré-escolar. As discussões apresentadas procuram articular teoria e prática por meio de análise bibliográfica realizada em alguns estudos que abordam a temática e da observação de aulas de língua inglesa desenvolvidas em turma de pré-escolar, na cidade de Abelardo Luz. Constatou-se que a aprendizagem significativa de uma língua estrangeira, por crianças pré-escolares exige que o processo de ensino não ocorra automaticamente, de forma mecânica, mas exige esforço, observação, análise, reflexão e mudança de postura ao longo do caminho, muitas vezes se faz necessária
Ao luar do sertão brilha uma luz fluorescente: releitura de um tema popular pela ótica da harmonia do século XX.
Bastante representativa do cancioneiro brasileiro a canção “Luar do Sertão” gera discussões
em torno de sua autoria. Não sendo meu objetivo tratar com profundidade dessa questão, analisarei aqui a segunda peça de uma suíte para violão solo chamada “Quadra” - composta de temas populares. A peça apresenta uma releitura da canção original à partir da ótica da harmonia do século XX. Textos de Persichetti, Hindemith e Brindle serão usados como fundamentação teórica para a análise harmônica da peça. Pretende-se, dessa forma, mostrar como uma melodia tonal pode dialogar com outras formas de organização das alturas
Uniformization, accessory parameters and modular forms
Several topics related to modular forms and to the accessory parameter problem for the uniformization of hyperbolic Riemann surfaces are discussed.
In the first part of the thesis we present an algorithm for the computation of the accessory parameters for the Fuchsian uniformization of certain punctured spheres. Then, via modular forms of rational weight, we show that the knowledge of the uniformizing differential equation leads to the complete knowledge of the ring of modular forms and of its Rankin-Cohen structure.
In the second part of the thesis, a new operator is defined on the space of quasimodular forms from an infinitesimal deformation of the uniformizing differential equation. It is shown that can be described in terms of well-known derivations on and certain integrals of weight four-cusp forms; the relation between the operator and a classical construction in Teichm"uller theory is discussed. The functions motivate the study and the introduction of a new class of functions, called emph{extended modular forms}. Extended modular forms are defined as certain components of vector-valued modular forms with respect to symmetric tensor representations. Apart from the functions examples of extended modular forms are: Eichler integrals, more general iterated integrals of modular forms, and elliptic multiple zeta values
Uniformization of punctured spheres and modular forms
We investigate some aspects of the classical accessory parameters problem
from the point of view of modular forms. We show that if
is an -punctured sphere, the whole ring of
modular forms can be constructed from a Frobenius basis of
solutions of the uniformizing differential equation of The argument is
based on the more general construction of certain rings of modular forms of
rational weight from the uniformizing differential equation of . In the
second part we present an algorithm for the computation of the uniformizing
value of the accessory parameters for certain punctured spheres. It is based on
the modularity of the holomorphic solution of the uniformizing differential
equation. The algorithm works uniformly in the case of four-punctured spheres,
and it can be used to compute the uniformizing accessory parameters for spheres
with punctures and enough automorphisms.Comment: 29 page
Modular forms, deformation of punctured spheres, and extensions of symmetric tensor representations
Let~X=\Po/\Gamma be an~-punctured sphere, . We introduce and study~ deformation operators on the space of modular forms~ based on the classical theory of uniformizing differential equations and accessory parameters. When restricting to modular functions, we recover a construction in Teichm\"uller theory related to the deformation of the complex structure of~. We describe the deformation operators in terms of derivations with respect to Eichler integrals of weight-four cusp forms, and in terms of vector-valued modular forms attached to extensions of symmetric tensor representations

Ramanujan systems of Rankin-Cohen type and hyperbolic triangles
In the first part of the paper we characterize systems of first order
nonlinear differential equations whose space of solutions is an
-module. We prove that such systems, called
Ramanujan systems of Rankin-Cohen type, have a special shape and are precisely
the ones whose solution space admits a Rankin-Cohen structure. In the second
part of the paper we consider triangle groups . By means of
modular embeddings, we associate to every such group a number of systems of non
linear ODEs whose solutions are algebraically independent twisted modular
forms. In particular, all rational weight modular forms on
are generated by the solutions of one such system (which is of Rankin-Cohen
type). As a corollary we find new relations for the Gauss hypergeometric
function evaluated at functions on the upper half-plane. To demonstrate the
power of our approach in the non classical setting, we construct the space of
integral weight twisted modular form on from solutions of
systems of nonlinear ODEs.Comment: 23 page
