The present work deals with a teaching experience with students beginning their formation in engineering at a university level. It deals with a non traditional course of Calculus using concept mapping as a teaching tool. Considering learning by the students to be a development of both cognitive aspects as well as non-cognitive aspects, concept mapping was integrated into the course in order to ...

When animals (including humans) first explore a new environment, what they remember is fragmentary knowledge about the places visited. Yet, they have to use such fragmentary knowledge to find their way home. Humans naturally use more powerful heuristics while lower animals have shown to develop a variety of methods that tend to utilize two key pieces of information, namely distance and orientat...

Remote sensing is increasingly used to assess disaster damage, traditionally by professional image analysts. A recent alternative is crowdsourcing by volunteers experienced in remote sensing, using internet-based mapping portals. We identify a range of problems in current approaches, including how volunteers can best be instructed for the task, ensuring that instructions are accurately understo...
