A transdisciplinary didactic proposal to recognize the dependence between variables in the laboratory of chemistry in high school

Abstract

On overall science, Mathematics play an indisputable rol. In order to identified causes and
phenomes, it is deeply necessary to determine the right relation among variables. In some courses teachers tend to exemplified drivel mathematic situations, not meaningful, therefor students find Mathematics useless. This could be remedied with a transdisciplinary approach. As an answer, this paper gives evidence of Mathematics skills developed under real problems, focusing on the “Theory of didactical situations”, starting from a lecture like situation at the Chemistry Laboratory where pupils must make calculations in order to get the mass and volume and be able to identify different environments in which they can apply meaningfully some math concepts.
