| Resumo: | This research aims at identifying the learning problems in newly
undergraduate students at university, interpreting the nature and causes of these
problems, offering subsidies to overcome these difficulties and enabling a
meaningful learning through which students give meaning to their learning. As an
object for this work was chosen the theme Chemical Bonds - where were studied
the forces between atoms to form molecules, compound ions and ionic crystalline
structures - and is characterized as one of the most important subjects of
Chemistry. In research, it was used a questionnaire with five open questions,
answered by 147 students from the early periods of degrees in Chemistry at
Universidade Federal do f Rio Grande do Norte. The answers revealed uncertainty
on the part of students, both conceptual and representation, with superficial
justifications, always using the octet rule to describe models of chemical bonds.
Results suggest that these students had inadequate training in high school and that
the examinations for entrance into the ranks were made according to flexible criteria
less demanding in terms of knowledge. These observations have led to the
conclusion that for future changes, it is necessary for high schools and in the early
periods in universities favoring the adoption of pedagogical approaches in context
and applying strategies to overcome the teaching of superficial memorization on
Chemical Bonds, which probably have applied to the teaching of other subjects of
chemistry |
