- ItemAtividades matemáticas investigativas e os desdobramentos de algumas etapas : um estudo de caso exploratório-descritivo realizado com uma professora atuante nos anos finais do ensino fundamental(Universidade Federal do Espírito Santo, 2016-12-23) Almeida Junior, Carlos Alberto Afonso de; Siqueira Filho, Moysés Gonçalves; Cesana, Andressa; Alvarenga, Flavio Gimenes; Bertini, Luciane de Fatima; Fassarella, Lúcio SouzaIt presents a study of a exploratory-descriptive case. It describes the attitudes and postures of a mathematics teacher while applying four mathematical investigative activities in two of her classes, in a municipal school located in São Mateus-ES. It identifies the potentialities, both positives and negatives, of mathematical communication and/or group work promoted from the given tasks, divided into four steps: planning, exploring, socialization and evaluation. It aims to answer the research problem: Which didactic-pedagogical practices can be identified in a mathematics teacher when working with investigative activities in the classroom?. It adopts as theoretical references the works of Ponte, Brocardo and Oliveira (2013); Ponte et al (1998a); Sancristán (2000). It emphasizes the problem of time administration, as consequence of external factors from the classroom. It concludes that, in spite of considering the mathematical investigation important to new content's treatment, the teacher indicated that it is not possible to always implement it, because it requires too many time to select and prepare the activities, and also it needs the help of others professionals for now, since she does not feel prepared to elaborate and/or plan the tasks.
- ItemO uso da astronomia como eixo temático motivador para introdução ao estudo de cinemática no ensino médio(Universidade Federal do Espírito Santo, 2016-03-22) Frinhani, Geysa; Pereira, Marcia Regina Santana; Kantor, Carlos Aparecido; Alvarenga, Flavio Gimenes; Bisch, Sergio MascarelloThis paper describes an educational intervention carried out in Physics classes with students from the first year of high school. This is the construction and application of a didactic sequence on kinematics, which used astronomy as a motivator theme and was based on the teaching and research for the theory of meaningful learning of David Ausubel. Was produced and applied by the author, characterizing it, therefore, as an action research, the nature of which is qualitative. The implementation of activities was held at the “Community Rural State School of Colatina” in 2015 and involved 36 students enrolled in the matutinal and Professor of Physics, also the researcher. The production of the adopted didactic sequence was based on the results obtained in the preliminary analysis of textbooks selected PNLD (nacional avaliation of textbooks) Physics in 2012. This analysis sought to identify the occurrence of specific content of Astronomy, and how these contents are covered in the books (curiosities, proposed exercises, introductory arguments, etc.). The objective of the research is investigate the possibility of effective use of content on Astronomy as a main axis for teaching kinematics. The instruments used for the production of data that will support the analysis were a field diary of the teacher-researcher, a diagnostic research with students and concept maps produced by students.
