Ensino-aprendizagem do filo porífera: abordagem didática utilizando modelos tridimensionais.

Abstract

Despite Porifera be conspicuous animais from the perspective of ecological aspects (part of many food webs, home providers to aquatic communities and some of their species have bioactive substances that are used in anticancer therapies), often the teaching-learning process of this zoological group does not happen effectively. This study aimed to describe the use of didactic approach using three-dimensional models of Porifera in the learning process at the Escola Estadual de Ensino Fundamental e Médio José Luiz Neto (Barra de Santa Rosa- PB). The research was conducted with 22 students of the 7th year of that school (day shift only in times of science lessons), during the period from September to November 2014. Data collection was made through the application of semi-structured questionnaires and classes to the students, as well as experiences with the construction of didactic models. Data carne quali quantitatively and presented in the form of texts and percentages. Among the main results, the majority (72.73%) of the students did not go to the beach environment until the time of the survey. In the experience of construction of didactic models, students were quite participatory. The focus on beachy environment did not change much of the numerical point of view at the two moments of this study. However, the negative feeling of tear in relation to the beach environment was numerically reduced after didactic intervention. When performing dynamic with biscuit dough, there was the importance of dynamic classes involving students directly with the topic. lt is considered that the theorical classes are indispensable, but must always be accompanied by dynamic activities, to avoid that it become tiresome.
