    Landscape metrics have been widely developed over the last two decades, although the question remains: How does landscape metrics relates with ecological processes? One of the major recent developments in landscape metrics analysis was the third dimension integration. Topography has an extremely important role on ecosystems function and structure, even though the common analysis in landscape ecology only conceives planimetric surface which leads to some erroneous results, particularly in mountain areas. The analytical process tested patch, class and landscape metrics behavior in 11 sample areas of 100 sqkm each in several topographical conditions of Central Alentejo. It is presented the significance analysis of the results achieved in planimetric and 3D environments

    Nowadays, the process of teaching and learning is changing from a traditional model in which teachers were the source of information for a model in which teachers appear as advisors who carefully observe students, assist in the selection of information by identifying their learning needs and support students in their autonomous study. In this chapter, the authors describe an approach used in curricular units of first year in Science and Engineer degrees, which results from a connection of three projects born in University of Aveiro: MEGUA, SIACUA and PmatE, and the interconnections of their informatics platforms. Although any scientific area besides mathematics can use this tool, the authors focus in a case study using an example on a specific topic of Calculus courses for first year students on Engineering: Sequences and Series of Functions. The methodology described allows teachers to achieve further goals on learning strategies and students to have enough material to practice.publishe
