Elaboração de sequência didática para área de ciências da natureza e suas tecnologias usando o açúcar como tema gerador

Abstract

The objective of this study was to elaborate a Didactic Sequence to work with high school students in Natural Sciences and its technologies, using the theme Sugars. The Didactic Sequence consisted of 4 Units, which were guided based on three pedagogical moments: Initial Problematization, Organization of Knowledge and Application of Knowledge. Within this approach, we sought to present the relationship of the theme with the chemical concepts of carbohydrates, glycoside bonds, functional groups, chiral carbon, measurement units such as cal, Kcal and Joule. Different didactic resources were explored in the elaboration of this material, such as article clippings, slides, videos and application. The material includes reading and writing activities, a questionnaire, a list of exercises, a mental map, a presentation and a crossword. In all parts of this Didactic Sequence, participation and reflection on excessive sugar consumption and the search for healthy and sustainable alternatives are encouraged. In order to verify the degree of satisfaction of the Educational Product elaborated, it was submitted to the Peer Evaluation Process, in which professors in the area of Natural Sciences and their Technologies answered a previously elaborated survey, based on three guiding axes: conceptual axis, pedagogical axis and communicational axis. The results of the peer evaluation showed the acceptance of the Educational Product developed regarding to the elaboration, contextualization and methodological resources used during the Didactic Sequence, in which they validate it as a material proposal that can subsidize the work of other teachers who seek to materials to guide their mediations, supported by the new approach given by the BNCC.
