Science education and teachers’ training. Research in partnership
No full textTaking into account the results of international researches concerning science knowledge of young people (TIMMS and PISA) and the worrying decrease in science disciplines’ roll in many countries, especially in European Community, our research group, cooperating within an international context, has designed materials in order to:
- improve motivation, learning and pupils' attitudes in science education
- develop a critical thinking, stimulate intuition and creativity
- increase scientific literacy in the community.
According to our experience, the most important school-related factor in raising student achievement is the quality of the teacher. Today, in the era of high standards and increased accountability, boosting teacher quality is more crucial than ever before. So we designed models of courses for pre-service and in-service science teachers as well offering the opportunity to cope with open problems, reflect about teaching models, discuss examples of good practices.
Kindergarten initial teachers had to reflect about some basic science concepts (space, time, forces, geometrical shapes), analyze their own mind representations, make simple experiments and design a short item.
Mathematics and Physics teachers were trained in laboratory with innovative and flexible devices which stimulated their motivation and creativity.
We investigated :
- variables affecting teaching models/styles and related students' learning
- students' assessment.
We present some results concerning kindergarten- primary - high school teachers' training.
Method
We interacted with initial and in-service science teachers mainly according with a critical social constructivist perspective, stimulating reflection and collaborative learning.
We submitted pre-school initial teachers to questionnaires to explore their ideas concerning both their teaching models and basic scientific concepts.
Expected Outcomes
Outcomes.
We have observed in teachers:
- increased awareness about conceptual knots concerning scientific concepts
- more sensitiveness and attention to students' involvement
- reflection about the effectiveness of their daily school work
- increased awareness about cooperative learning.

LOCALIZATION OF QUANTUM FIELDS ON BRANES
No full textA mechanism for localization of quantum fields on a s-brane, representing the boundary of a (s + 2)-dimensional bulk space, is investigated. Minkowski and AdS bulk spaces are analyzed. Besides the background geometry, the relevant parameters controlling the theory are the mass M and a real parameter eta, specifying the boundary condition on the brane. The importance of exploring the whole range of allowed values for these parameters is emphasized. Stability in Minkowski space requires eta greater than or equal to -M, whereas in the AdS background all real eta are permitted. Both in the flat and in AdS case, the induced field on the brane is a non-canonical generalized free field. For a suitable choice of boundary condition, corresponding to the presence of a boundary state, the induced field on the brane mimics standard (s + 1)-dimensional physics. In a certain range of eta, the spectral function in the the AdS case is dominated by a massive excitation, which imitates the presence of massive particle on the brane. We show that the quantum field induced on the brane is stabl

THREE MANIFOLD INVARIANTS AND THEIR RELATION WITH THE FUNDAMENTAL GROUP
No full textWe consider the 3-manifold invariant I(M) which is defined by means of the Chern-Simons quantum field theory and which coincides with the Reshetikhin-Turaev invariant. We present some arguments and numerical results supporting the conjecture that for nonvanishing I(M), the absolute value \I(M)\ only depends on the fundamental group pi(1)(M) of the manifold M. For lens spaces, the conjecture is proved when the gauge group is SU(2). In the case in which the gauge group is SU(3), we present numerical computations confirming the conjecture
BOSONIZATION AT FINITE TEMPERATURE AND ANYON CONDENSATION
No full textAn operator formalism for bosonization at finite temperature and density is developed. We treat the general case of anyon statistics. The exact n-point correlation functions, satisfying the Kubo-Martin-Schwinger condition, are explicitly constructed, The invariance under both vector and axial transformations allows to introduce two chemical potentials, which give rise to non-vanishing persistent currents. Investigating the exact momentum distribution, we discover anyon condensation in certain range of the statistical parameter, which shows that condensation is not an exclusive prerogative of bosonic systems. As an application of the general formalism, we solve the massless Thirring model at finite temperature, deriving the charge density and the persistent current
