O porquê do Azul do Céu e Avermelhado do Pôr do Sol: um estudo de caso dos perfis conceituais dos estudantes universitários do sertão paraibano.

Abstract

This study presents the analysis of the different conceptual profiles, regarding the coloration of the sky presented by students from different periods of the Physics Undergraduate course at the Teacher Training Center of the Federal University of Campina Grande, in the city of Cajazeiras, Paraíba. The notion of Conceptual Profile, proposed by Mortimer (1995), is inserted in the perspective of discussions of students' prior conceptions and the idea of conceptual change. Thus, subjects can develop different conceptual profiles for acting in different contexts. For the development of this research, the qualitative methodology was adopted for the analysis of the Conceptual Profile zones on the exposed problematic. In order to know more about the different Conceptual Profiles of the students of a Physics Undergraduate course, throughout their academic trajectory, we chose to use an online questionnaire to recognize these profiles. The questionnaire is composed of four open questions, and was applied to the students of the Degree in Physics course in different stages of the course. This questionnaire was applied virtually, using the "Google Forms" platform. The Degree in Physics course had a total of 146 students enrolled at the time of the research. After the questionnaires were sent out, 17 questionnaires were answered, thus providing the analysis of the answers and the formation of four (4) Zones of Conceptual Profiles: Simplistic Notion; Conceptual Ingenuity; Notion Susceptible to Evolution; Understands the relationship of the colors of the sky and the Dispersion of Light; Descriptive Analysis of the Images; Relates the colors of the sky to the Refraction of Light; Knowledge concerning the Phenomenon; Conception consistent to the Dispersion of Light; Relationship to the Dispersion of Light; Understanding consistent to the Refraction of Light. By means of a case study, we analyzed the different conceptual profiles presented by future Physics teachers, during the different periods of the Physics Undergraduate course, regarding the coloration of the sky. The study allowed for reflection about the different profiles built throughout the undergraduate course.
