A argumentação e a experimentação investigativa no ensino de matemática: o problema das formas em um clube de ciências
(Universidade Federal do Pará, 2017-05-05) ALMEIDA, Willa Nayana Corrêa; MALHEIRO, João Manoel da Silva; http://lattes.cnpq.br/7502225344402729
The present study objective to analyze the contributions of the interventions of the teacher-monitor for the emergence and development of the argumentation among students participating in the Science Club "Prof. Dr. Cristovam W. P. Diniz", of the Federal University of Pará - Campus Castanhal, during an investigative experimental activity on the introductory concepts of area and perimeter. It Emerged from the reflections of the researcher during her personal and professional experiences in the classroom, and that contribute to the constitution of our identity as educator of Mathematics. In view of this, we apply a sequence of teaching based on the stages of investigative experimentation, in which we seek to identify, in our interventions as teacher-monitors, the pedagogical and epistemological purposes expressed to favor the argumentation among the students. Regarding the students' statements, we tried to verify in the argumentative process developed, both the elements and the structure according to the of Toulmin’s Pattern (2001), such as the epistemological operations presented by students expressing the relations that occurred during the construction of mathematical knowledge. The research is characterized as qualitative, in which we use as video recording instruments, video recordings, photographs, audio recordings and field notes, with subsequent transcription of the subjects' speeches. For the interpretation of the information collected, we chose to use Content Analysis. The space investigated is considered an alternative environment destined for teaching, research and extension of didactic actions turned to Science and Mathematics. The participants were four students of the fifth year and three of the sixth year, totalizing seven subjects. During the analysis, it was possible to identify, in each of the episodes considered more prominent, that our interventions as teacher-monitor had great relevance, since from the developed epistemological purposes and pedagogical actions it was possible organize and guide the investigative activity so that it helps in the emergence of argumentation and the construction of mathematical knowledge. We verified that emerged argumentative organisms according to the Toulmin pattern, being constituted of data (D), conclusion (C), warranty (W), backing (B), modal qualifier (Q) and refutation (R). In relation to the epistemological operations presented by the students in the development of the argumentation, we perceive that various forms of action and thought have arisen, being mainly explored deduction, induction, causality, definition, classifying, appeal to analogies and attributes, consistency with experience and plausibility. The final product generated by the research consists of a video guidance that explains the stages of investigative experimentation and evidences the attitude of the educator for the emergence and development of argumentation among students.

Produção de audiovisual sobre a aprendizagem baseada em problemas: passos de sua constituição em um curso de férias em Mãe do Rio (PA)
(Universidade Federal do Pará, 2017-07-01) ARNAUD, Orlando Temistocles Cruz; MALHEIRO, João Manoel da Silva; http://lattes.cnpq.br/7502225344402729
In the last three decades, didactic audiovisual has been consolidating as an important pedagogical instrument for teaching science, being potentialized when combined with new methodologies such as Problem-Based Learning (PBL). This research aims to identify the characteristics of the PBL manifested in the dynamics of the Vacation Course and produce an audiovisual. For the constituting of the video, the videotapes of the interactions between a Teacher-coordinator, two monitors and six students of the basic education participants of a Vacation Course occurred in Mãe do Rio (PA) were used. The research presents a qualitative approach, with participant observer. The audiovisual was evaluated by six teachers and two specialists through questionnaires, which are presented in Appendices A and B, in which they present seven questions, six of which are subjective and one of multiple choice. The answers were based on the reference of Malheiro (2005) to the PBL, while the categories and indicators were based on the works of Cabero (2001) and Gomes (2008). The interpretations from the questionnaires indicate that the stages of the PBL are evident in the video and that its content contributes to educators to develop the methodology in the classroom. In addition, the audiovisual is appropriate to begin the study of the subject on group of fish. The tutorials make clear how to develop the PBL present in the audiovisual, which, in turn, pedagogically promotes improvements in teachers' classes. The categories and indicators analyzed were evaluated, for the most part, as positive and satisfactory, they are: sufficiency of the amount of information; size of the graphic elements: photos, subtitles, etc; technical and aesthetic quality of the visual elements; dialogues; technical and aesthetic quality of ambient sound, vignettes and audio/locution; inclusion of elements to highlight important elements; adequate and sufficient video duration; allows complementary activities at the same time of class; valuation of exposure, discussion, criticism or practice/application; creation of learning situations is facilitated; pedagogical proposal appropriate to the target audience.
