The dissertation presents the report of an instructional material MI, applied to the
students of the 1st year of Technical High School. The topics presented here,
vectors, gravitational field, electric field and electric potential, are collected in the
textbooks analyzed, adopted by the National Book and Teaching Material
Program (PNLD 2015). However, for the student of Technical Education, some
subjects such as Electric Field and Electrical Potential are necessary already in
the first year of the course and these same subjects are charged in the PNLD
books, only in the third year. In order to assist the work of the first year teachers
of the technical courses, this MI was prepared, but inserting the concepts of
electric field and electric potential at the beginning of the course and not only of
the third year. This material was elaborated based on the theoretical aspects of
Ausubel's Significant Learning Theory.
