A educação escolar no contexto das Tecnologias da Informação e da Comunicação (TIC): desafios e possibilidades para a prática pedagógica curricular

The paper presents some reflections, in the form of questions, about the challenges and possibilities of education in respect to integration of information technology and communication in the school curriculum. For this, we present: initial considerations on contemporary education and the urgent need to rethink the teaching curriculum on information society and knowledge, perspectives on the school curriculum and the moments for which it permeates even be translated into everyday curriculum for teaching practices , and finally, emphasizes the need for integration of technologies, so cross-curricular teaching practices through inter-and transdisciplinary projects.

As diretrizes curriculares para os cursos de Educação Física no Brasil: uma breve revisão cronológica e análise desse processo sobre as implicações para a formação profissional

The law of Guidelines and Bases for National Education-LDB established the need to ensure at Universities a greater flexibility in the Organization of courses and careers, taking into account the heterogeneity of prior education and training, as well as the expectations and interests of students. Since the deployment of the first courses of Physical Education in Brazil, in the 30 's decade, the formation was only in Degree Course. On a pioneer way, resolution CFE 031987 allowed the Universities could organise their own pedagogical projects and curriculum, allowing even the Bachelor Course contemplating the dynamics of the evolution of the area and encouraging a change in attitudes of professionals. The Bachelor Course, with an offer of disciplines to other areas higher than education, openness also allowed to research, promoting an increasing interaction of the Physical Education with other professions od health. Physical education stands out as interareas instrument in the promotion of health and quality of life of the population. With the regulation of the Profession through the law No. 9696/98, grows the discussion around the definition of professional delimitations in this close relationship with other areas. With the need for a reformulation in teaching projects, Degree and Bachelor Courses, express the new curricular guidelines and resolutions of the MEC, as well as the professional delimitations by CONFEF for each formation. Given these aspects, the objective of the present study was to describe the chronology of such facts and a expose a critical opinion of the authors about the course and consequences of this process.

Microstructure and corrosion resistance of inorganic-organic (ZrO2-PMMA) hybrid coating on stainless steel

Zirconia-polymethylmetacrylate hybrids prepared by a sol-gel method were deposited by dip-coating on stainless steel to improve the resistance against wet corrosion. The effect of the concentration of polymethylmetacrylate and the number of coating applications on the microstructure and corrosion performance of coated samples was investigated. The microstructural properties of samples was analyzed by scanning electron and atomic force microscopy, adhesion tests and profilemeter measurements. The electrochemical corrosion was evaluated through potentiodynamic polarization curves at room temperature. Results show that the sample prepared with 17 vol.% of polymethylmethacrylate has a maximum corrosion resistance, smaller roughness, are hermetic and adherent to the substrate. This film increases the life time of the stainless steel by a factor 30. (C) 1999 Elsevier B.V. B.V. All rights reserved.

Energy efficiency for standard penetration tests

The need for standardization of the measured blow count number N-spt into a normalized reference energy value is now fully recognized. The present paper extends the existing theoretical approach using the wave propagation theory as framework and introduces an analysis for large displacements enabling the influence of rod length in the measured N-spt values to be quantified. The study is based on both calibration chamber and field tests. Energy measurements are monitored in two different positions: below the anvil and above the sampler. Both experimental and numerical results demonstrate that whereas the energy delivered into the rod stem is expressed as a ratio of the theoretical free-fall energy of the hammer, the effective sampler energy is a function of the hammer height of fall, sampler permanent penetration, and weight of both hammer and rods. Influence of rod length is twofold and produces opposite effects: wave energy losses increase with increasing rod length and in a long rod composition the gain in potential energy from rod weight is significant and may partially compensate measured energy losses. Based on this revised approach, an analytical solution is proposed to calculate the energy delivered to the sampler and efficiency coefficients are suggested to account for energy losses during the energy transference process.
