In this article we aim to broaden the discussion about mathematical education of students of Middle Level Professional Education in Brazil (EPTNM), focusing on the issue of interdisciplinarity, emphasized in official documents as one of the organizing axes of the curriculum for this type of education. Studies in this field are justified by the growth of this modality in the Brazilian educational system, as well as the lack of specific investigations in the field of Mathematics Education about it. Our research is guided by the questions: Can the adoption of an interdisciplinary approach to organizing the curriculum contribute to building links between technical professional education and the more academic education characteristic of Middle Level education? What are its potentialities for promoting more meaningful learning of mathematical content in this type of education? We conclude that the superficiality with which the theme of interdisciplinarity has been handled, and the lack of contextualization in other research related to it in mathematics education, are some of the reasons for not implementing the idea successfully. In this article, we discuss the contribution of different authors who research the theme and include proposals to explore Ethnomathematics and Modeling as possibilities for curriculum enrichment of the EPTNM, linking different areas of knowledge and contextualizing math in the reality of the world of work.

The purpose of this research was to present the principles for the implementation of a future water body classification program at the UGRHI-1 (Management Unit of Water Resources-1/São Paulo, Brazil) using qualitative and quantitative water modeling. Our study area was in Campos do Jordão, a city in the state of São Paulo, specifically in the Perdizes river watershed, which is included in the UGRHI-1. The water quality assessment used a modeling mehtodology that can support a future study for the classification of water bodies in the region. The behavior of DO and BOD parameters was assessed in the water quality scenarios, considering the variations of flows, loads, reductions in withdrawals and different efficiencies in sewage treatment. The model used was QUAL2E developed by USEPA (United States Environmental Protection Agency) that received a new graphic interface named QUAL2R model. The reference flows Q7,10, Q95% and Qm used were obtained through the DAEE (Department of Water and Electric Energy) hydrologic regionalization method. It was noted that of the 9 proposed scenarios, only scenario 6 that was predicted in the flow regime Qm with the existence of a treatment system capable of removing 93% of the BOD, in the Perdizes River remained 67.5% of the time in class 2. Scenario 8 predicted a 50% reduction in In scenario 8 a reduction of 50% in the flow captured in CA-04, associated with the efficiency of 93% of BOD removal keeping the river in class 2. In scenario 9 the minimum required efficiency in sewage treatment in the flow regime Q95% for keeping the river in class 2 was also calculated and the value of 94.7% was obtained.

A modelagem matemática associada ao conhecimento da variabilidade dos atributos do solo e mapeamento das formas do relevo pode auxiliar no manejo da fertilidade do solo em usinas sucroalcooleiras. O presente trabalho teve como objetivo avaliar o uso da geoestatística e da modelagem matemática na estimativa de custos de fertilização, em diferentes formas do relevo. em uma área de 200 ha, foram identificadas duas formas de relevo, uma côncava e outra convexa, sendo os solos coletados nos pontos de cruzamento de uma malha, com intervalos regulares de 50 m, perfazendo um total de 623 pontos. As amostras foram submetidas a análises químicas, e, posteriormente, os dados foram avaliados por meio da estatística descritiva, geoestatística e modelagem matemática. Os resultados mostraram que, quando as formas do relevo são incorporadas às análises geoestatística e de modelagem matemática, ocorre aumento na eficiência de aplicação do calcário, fósforo e potássio no solo.
