software Tracker.

In most high schools, the education of Physics still maintains its
focus on traditional education, with classes centered on the
teacher, unidirectional and always from top to bottom. However,
in face of technological advances, the development of new
theories of education and learning methodologies of the domain
of Physics, this dissertation aims to break the barrier of
traditional teaching and the new school, bringing as a main
focus the learning as you do, and make the student responsible
for their own education, developing protagonism and
investigative character. For that, we will use John Dewey's
theory in which the process of teaching-learning is centered on
an individual's lived experiences. Vygotsky's theory also brings
up that the education is related to the relationship between
individuals and society. In the methodology an activity will be
proposed which investigates the relation between frictional force
and contact area of an object and the surface it supports, based
on active methodologies, specifically in Problem-based Learning
(PBL) combined with didactic resources and using the Tracker
software to analyze videos as a mean of educational product. It
is important to point out that this educational product will have
an institutional character and will be consulted by other teachers
to be replicated in different schools. The results of this
dissertation, analyzed after application at Ariano Vilar Suassuna
Technical School, located in the city of Garanhuns, in the state
of Pernambuco, in a 1st year of high school class, highlight the
student's independence in the construction of their own
education, being critical and dealing with constructive situations
in the phenomenological sense of the concepts involving the
frictional force and its relation with contact surfaces
