One of the difficulties presented in
teaching mechanical vector is the visualization and interactivity issue. The
use of static resources, such as lecture classes and the traditional media
used, most often, does not allow a satisfactory teaching and learning of the
content. An effective learning of the content is important for the engineers
during the training, but the methodological alternatives that can provide the
assimilation of the content in the easiest way, in most of the times are not
available in the courses for teachers.
GeoGeabra software, which is a dynamic
geometric environment that allows the interactive exploration of algebraic and
geometric concepts, was used in the development and proposal of didactic
solutions for disciplines in General Mechanical Engineering courses, developing
activities in the form of computation tools, so-called potentially meaningful
material. It was observed as necessary conditions in MLT―Meaningful Learning
Theory, theoretical basis that contextualizes that new knowledge starts from
the interaction with the previous cognitive structure of the individual
knowledge.
Nowadays, computerization was not contested
anymore, because the first contact with the computer technologies came from
childhood; however, it was observed that lately technological insertions came
from previous experiences at school.
This paper presents didactic solutions to
the Vector Mechanics subject, which aims to teach the calculation and the
representation of the acting forces on a given particle in space. It is about
developed and applied activities in GeoGebra software, called potentially
meaningful materials. The whole proposal was based on MLT―Meaningful Learning
Theory, proposed by David Ausubel, in order to contribute to a more efficient
learning in general disciplines of engineering courses.
