13. Da licenciatura ao início da docência : vivências de professores de matemática na utilização das tecnologias da informação e comunicação
This research aims to investigate the contributions of UFSCars Teaching License in Mathematics and the experiences of teachers at the beginning of their careers when introducing and using the Information and Communication Technology ICT in their classes. This is a qualitative-based study which consisted of three different moments: in the first one, I used a

14. Um espalhador de baixo custo de fase estacionária em placas para cromatografia em camada delgada
Chromatography is a means of separating mixtures into their several components. TLC, mainly a liquid/solid process, is one of the separation techniques most often used. It is indispensable in laboratories dealing with natural products, organic and analytical chemistry. Commercial chromatography plates are offered at relatively high cost. In this work the con

15. Categorias para a seleção de experimentos de química no ensino médio : um estudo comparativo das prioridades dos professores e licenciados em formação
Experimental laboratory activities are considered essential for learning chemistry. In this dissertation, this theme of experimentation was explored to establish the relative importance of the selection categories for experiments. The research was of quantitative nature, where a comparative study was carried out with 58 chemistry teachers in high schools in

16. Um fotômetro multi-led microcontrolado, portátil e de baixo custo
A microcontrolled, portable and inexpensive photometer is described. It uses six light-emitting diodes (LEDs) as radiation sources and a phototransistor as detector, as well as a microcontroller (PIC - Programmable Controller of Interruption). This device provided total autonomy to the proposed photometer, which was successfully applied to determination of F

17. Hypertext and the training process: contributions and/or obstacles for education. / Hipertexto e processo formativo: contribuições e/ou obstáculos para a educação.
The unbalanced advance between infra-structure and supra-structure, which material base develops at a faster pace than society evolution as a whole, sharply acts on the man who gradually loses awareness about his own significance as an individual, leaving even more fragile those ties binding him to tradition and to a deeper, longer lasting and enhanced knowl

18. Uma interface lab-made para aquisição de sinais analógicos instrumentais via porta paralela do microcomputador
A lab-made interface for acquisition of instrumental analog signals between 0 and 5 V at a frequency up to 670 kHz at the parallel port of a microcomputer is described. Since it uses few and small components, it was built into the connector of a printer parallel cable. Its performance was evaluated by monitoring the signals of four different instruments and

19. Programa de gerenciamento de resíduos dos laboratórios de graduação da Universidade Regional Integrada do Alto Uruguai e das Missões - Campus Erechim
This work presents a proposal for the management of residues from teaching laboratories. The main goals of the proposal are: scale reduction of experiments, reuse of residues as raw materials for new experiments and appropriate treatment and storage of residues. The methodology includes standardized labels for residue classification and registration of exper

20. Relato de uma experiência pedagógica no ensino de química: formação profissional com responsabilidade ambiental
The toxic heavy metals can not be transformed in other less toxic substances as organic wastes through chemical process. Various chemistry courses at Faculty of Philosophy, Sciences and Humanities (FFCLRP/USP) use heavy metals in their experimental classes. In this context, a course were created: "Heavy Metal Wastes generated in the teaching and research lab

21. Um banho termostático de baixo custo (temperatura ambiente até 0ºC)
Thermal baths to decrease ambient temperature are an indispensable tool for most research and teaching laboratories, especially those in tropical or equatorial regions. A simple and inexpensive thermal bath has been developed based on a scratched compressor. It has three possible setups for cooling: sample immersed into the bath, sample flowing through the b

22. A utilização das tecnologias da informação pelo corpo docente no curso de graduação em administração da Universidade Regional de Blumenau - FURB
The accelerated technological innovation is promoting fast changes in the atmosphere of the businesses, demanding from the organizations adaptation and development in new ways to compete and to differ of the competition. Before this scenery, the higher education institutions cannot be exciuded of that reality. especially the degree course in Administration,

23. Method for Collecting Air-Water Interface Microbes Suitable for Subsequent Microscopy and Molecular Analysis in both Research and Teaching Laboratories
A method has been developed for collecting air-water interface (AWI) microbes and biofilms that enables analysis of the same sample with various combinations of bright-field and fluorescence light microscopy optics, scanning and transmission electron microscopy (TEM), and atomic force microscopy. The identical sample is then subjected to molecular analysis.
