Interação de crenças em contexto colaborativo virtual de aprendizagem de línguas

This article mainly aims at addressing issues of the complexity and dynamics of beliefs in collaborative contexts for language teaching and learning, such as Teletandem. On the assumption that beliefs are dynamic and can be (re)signified, we present some of the results of a research about the interaction of beliefs of two Teletandem partners, a Brazilian and an Italian undergraduate student, addressing moments of convergence and divergence, as well as their possible origins and (re)significations from lived experiences. The results show how the Teletandem context can become a field for conflicts and clashes of beliefs and how the mediation as well as the relationship between the participants becomes essential for the conduction of language learning in collaborative environments.

Crenças sobre compreensão oral em língua estrangeira de alunos concluintes de um curso de Licenciatura em Letras

In this article we present and discuss a number of beliefs about listening comprehension among students who were in their last year of a teachers’ certification Letters course in Italian and Portuguese. The data were collected by means of questionnaires answered by all the participating students, logs and interviews conducted with five of the participating students, classroom observation, lessons recorded on audio and video, and diaries. The study is supported by a rationale on beliefs and on definitions of listening comprehension as a skill. The analysis indicate that a number of students showed lack of motivation and low expectations about developing oral comprehension skills due to several drawbacks in foreign language learning during their teacher education course. However, other beliefs that emerged from the data, such as the importance of visual aids to help understanding an oral text, seem to have a positive effect towards a satisfactory proficiency level in oral comprehension.

General structures of Hamiltonian hierarchies

Three dimensional exactly solvable quantum potentials for which an extra term of form 1/r(2) has been added are shown to maintain their functional form which allows the construction of the Hamiltonian hierarchy and the determination of the spectra of eigenvalues and eigenfunctions within the Supersymmetric Quantum Mechanics formalism. For the specific cases of the harmonic oscillator and the Coulomb potentials, known as pseudo-harmonic oscillator and pseudo-Coulomb potentials, it is shown here that the inclusion of the new term corresponds to rescaling the angular momentum and it is responsible for maintaining their exact solvability.

REDUCTION OF TODA LATTICE HIERARCHY TO GENERALIZED KDV HIERARCHIES AND THE 2-MATRIX MODEL

Toda lattice hierarchy and the associated matrix formulation of the 2M-boson KP hierarchies provide a framework for the Drinfeld-Sokolov reduction scheme realized through Hamiltonian action within the second KP Poisson bracket. By working with free currents, which Abelianize the second KP Hamiltonian structure, we are able to obtain a unified formalism for the reduced SL(M + 1, M - k) KdV hierarchies interpolating between the ordinary KP and KdV hierarchies. The corresponding Lax operators are given as superdeterminants of graded SL(M + 1, M - k) matrices in the diagonal gauge and we describe their bracket structure and field content. In particular, we provide explicit free field representations of the associated W(M, M - k) Poisson bracket algebras generalising the familiar nonlinear W-M+1 algebra. Discrete Backlund transformations for SL(M + 1, M - k) KdV are generated naturally from lattice translations in the underlying Toda-like hierarchy. As an application we demonstrate the equivalence of the two-matrix string model to the SL(M + 1, 1) KdV hierarchy.

ON DISCRETE SYSMMETRIES OF THE MULTI-BOSON KP HIERARCHIES

We show that the multi-boson KP hierarchies possess a class of discrete symmetries linking them to discrete Toda systems. These discrete symmetries are generated by the similarity transformation of the corresponding Lax operator. This establishes a canonical nature of the discrete transformations. The spectral equation, which defines both the lattice system and the corresponding Lax operator, plays a key role in determining pertinent symmetry structure. We also introduce the concept of the square root lattice leading to a family of new pseudo-differential operators with covariance under additional Backlund transformations.

Toda lattice realization of integrable hierarchies

We present a new realization of scalar integrable hierarchies in terms of the Toda lattice hierarchy. In other words, we show on a large number of examples that an integrable hierarchy, defined by a pseudo-differential Lax operator, can be embedded in the Toda lattice hierarchy. Such a realization in terms the Toda lattice hierarchy seems to be as general as the Drinfeld-Sokolov realization.
