Relato de uma experiência: recuperação e cadastramento de resíduos dos laboratórios de graduação do Instituto de Química da Universidade Federal do Rio Grande do Sul

An experience aiming to promote a residue interchange and recovery between the teaching laboratories of the Chemistry Institute of this University is described. At the present, several residues interchange have already appeared as advantageous. To make the work easier, a software has been developed in order to keep a record of all the residues generated by the teaching laboratories. Standard labels have been developed for the residues in order to organize them. The software and the label design are described.

Um objeto de aprendizagem para o ensino de Química Geral

A learning object for General Chemistry teaching Freshman students usually have difficulties in General Chemistry’s discipline. The objective of this proposal is to contribute to the improvement of their learning activity, through the development of a hypertext. It comprehends the contents of a discipline that the Chemistry Institute of Federal University of Rio Grande do Sul (UFRGS) offers to the students whose Major is in: Chemistry, Chemical Engineering and Materials Engineering. Each subject is presented through different approaches: written and illustrated texts, solved and discussed exercises, problems with different difficulty grades, and complementary information, where the relation and integration with others subjects and as well with every day life aspects can be done. Those students who used the material made a positive evaluation. However, many of them showed some resistance to methods, which use study strategies mediated by computer, without a teacher to guide them.
