Robotics and entrepreneurship for a better society: opening doors to mobility
This article reports the development
of an educational robotics project at the Basic
School (2nd and 3rd cycles) André Soares in
Braga, with students from 6th grade, integrated
in an international cooperative partnership for
innovation and good practices of the European
Erasmus+ programme.
This project was initially designed to address
the need to share innovative teaching practices
through the development of new methodologies
and multidisciplinary approach in teachinglearning
processes in the 2nd and 3rd cycles of
basic education combined with the stimulation
of entrepreneurial skills and co-creation of
knowledge. From the beginning, the project had
the collaboration and support of the Hands-on
Science Network Association, having given rise
to the submission of an application to the 13th
edition of the contest “Projeto Ciência na
Escola” of the Ilídio Pinho Foundation on the
topic “Science and Technology at the service of
a better world”. This application has been
selected for the 2nd phase of the competition
and obtained financial support for the
development of activities which gave an added
dimension to the project, attracting and further
motivating students for learning science and
the choice of technology areas.
Students were challenged to identify a
situation/problem and find a possible
solution/answer in the context of educational
robotics. Thus, there was the study of the
LEGO MINDSTORMS NXT programming
environment for programming routines or
scripts and simultaneously the work
methodology hands-on was implemented using
participative methodological approaches,
enhancing the development of key skills and
entrepreneur spirit. At first, students’ creativity
was stimulated through the ideas generation
process called SCAMPER, channelling it to
solve situations/problem where the students'
task was to unlock a situation and optimize it.
From a simple stick and a simulation of a path
for blind people, ideas were collected to
innovate this object, in order to promote a more
efficient and fairer mobility. With the
collection/gathering of ideas/suggestions, a
guiding principle for our project was developed
giving an intended metacognitive knowledge.
Starting with the acquisition of this knowledge,
students focus on building and programming
robots LEGO MINDSTORMS NXT, developing
the prototype of a smart and innovative cane
for the blind people. This is an interactive
process that combines the concrete and the
abstract in solving a problem involving steps
such as: design, implementation, construction,
automation and control mechanism. In all of
these steps the construction of knowledge took
place, arising from different scientific fields
(science, mathematics, physics, technology),
as well as the acquisition of transversal skills.
The work focused mainly on the dynamics of
the process rather than the products or results.
Many citizenship skills were developed when
creating a tool to minimize the difficulties and
obstacles faced by blind people, enabling the
improvement of their quality of life. It was
observed, from certain experimental activities,
that one can transfer new skills and knowledge
acquired at school to everyday life
Genetic improvement of forest tree species.
Brazilian forestry sector is considered one of the most developed in the world, being the base for important industrial segments which use wood as raw material. Tree breeding has played an important role on improving the competitiveness of Brazilian forestry-based companies, especially for its positive reflexes on increasing adaptation, forestry productivity and wood quality. In spite of the importance of other forest trees for the economy, such as Schizolobium, Araucaria, Populus and Hevea, the main genera under genetic improvement in the country are Eucalyptus, Pinus, Acacia and Tectona. They are used by industries like pulp and paper, siderurgy, tannin, chips for exportation and lumber, constituting an important source of revenues for the Brazilian?s economy, besides their positive social and environmental impacts. This paper presents a generic approach to genetic improvement aspects of these four major genera currently undergoing breeding in Brazil.Especial issue
