A pesquisa no ensino de química: a abordagem didática da simulação virtual e da experimentação problematizadora

Abstract

The research aimed to analyse the contributions and potentialities of the didactic approaches of virtual simulation and experimental practical for questions in the chemistry as formative principle, on high school. The content addressed was “The Physical States of Material”. It was employed how a computer tool the virtual simulation states of material PhET (1.10) from Colorado University, because it presents ludic, interactive, dynamic features and it makes possible the visualization , on real time, of the motion and interation particles. For the experiment it was held the naphtalene physical state change, developed by the students, and oriented by the theacher, Who conducted the students to develop the curiosity, investigation and Discovery. Each tool presented a peculiar feature and different qualities, arousing the interest and motivation of the students. It was used the methodological proposal adapted based on the Paulo Freires’s approach whom consists to divide the educational activities in three pedagogical moments (3MP), to know: Inicial problematization, the arrangement of the knowledge and the knowledge application. The development of the study hás ensued by workshop, in a space of time in 3h/weekly class during 13 meetings, in a first year class on the state public high school from Manaus. We tool on the research-action how guiding of the activities that were fulfilled. We perceived the research was qualitative and descriptive. The data were obtained by observation, questionaire appointments and the data were processed according to content analysis. The results show that the used approach is promising because it promoted significantly, the reconstruction of knowledge developing the student’s cognitive skills.
