- ItemO professor de matemática e o ensino de frações: um estudo investigativo(Instituto Federal de Educação, Ciência e Tecnologia Farroupilha, 2023) Galarça, Luísa Dinele Montanha Marques; Lutz, Mauricio RamosThe present research aimed to investigate how teachers articulate the content of fractions in the final years of elementary school, based on what is stated in textbooks and the Base Nacional Comum Curricular (BNCC). The data were collected from an interview with seven mathematics teachers who are working in the classroom. The interviewees commented that one way to facilitate the teaching of fractions is to work with concrete materials. With the use of these materials the student may have fewer difficulties in his learning, because he can more easily perceive the concept. Moreover, it was found that in the books approved by the National Textbook Program the concept of fraction is always presented from a contextualization, however, it is not presented explicitly. We also noticed that the interviewees have knowledge about the BNCC. In addition, they commented on the importance of initial and continuing education courses to study it, because this is how teachers can appropriate the content, competencies and skills that should be developed at each stage of the student's school life.
- ItemInvestigação de práticas e saberes docentes dos professores de ciências sobre a temática "meio ambiente" nas escolas municipais de Alegrete/RS.(Instituto Federal de Educação, Ciência e Tecnologia Farroupilha, 2023) Mann, Moacir Silvestre; Dalosto, Marcelo MarchetEnvironmental education (EE) is considered a cornerstone of elementary school, related to the development of critical thinking and creativity, and it inspires students to involve themselves in their communities. It also favors the understanding of the importance of a healthy environment and provides the basis for living a sustainable life. In this context, teachers have a significant role, as they influence the development of their students and can stimulate them to become responsible towards nature, having the responsibility to promote the values and ethics necessary to protect the environment. The objective of this study was to investigate how the elementary school teachers of the municipality of Alegrete (Rio Grande do Sul state) perceive the environment and the teaching-learning process related to this theme. A quiz was used for this, with 26 questions distributed in 3 axes: I) Knowing the professional profile of the teachers working with EE in schools; II) Analyze their perceptions concerning the teaching of issues related to the environment; and III) Verify the didactic strategies used to teach subjects related to the environment. These questions were shared with the teachers using online forms. Most of the teachers consulted consider the environment as an appealing theme for their students, and do not perceive many difficulties to develop this theme in their classes, but they highlight the importance of continuing education on this issue. Fulfilling this gap is important for a teaching practice that implements EE in a truly transformative way.
- ItemPercepções de docentes iniciantes sobre o uso das tdic nas suas dinâmicas de ensino de matemática(Instituto Federal de Educação, Ciência e Tecnologia Farroupilha, 2023) Vargas, Leonardo Alves; Bueno, Rafael Winícius da Silva; Bueno, Rafael Winícius da Silva; Lopes, Mirian Marchezan; Pompermayer, Eduardo MeligaThe present work is characterized as a qualitative research, whose objective is to investigate the perceptions of beginning mathematics teachers, who work in state schools located in Alegrete - RS, about the use of Digital Information and Communication Technologies (ICT) in their teaching dynamics. It presents in its theoretical framework a brief explanation about the educational use of ICT, resorting mainly to the ideas of Seymour Papert's Constructionism (1928-2016). Based on this theory, the information was collected through a questionnaire sent to math teachers with up to 5 years of teaching experience. The obtained answers were treated, using as main method the Textual Discourse Analysis (TDA). The results portray that for the participants, the use of the DTIC interferes positively in the promotion of a greater interest and active participation of the students in their process of knowledge production
- ItemInvestigando a aprendizagem de matemática nos anos finais do ensino fundamental em escolas estaduais de Alegrete/RS em tempos de pandemia(Instituto Federal de Educação, Ciência e Tecnologia Farroupilha, 2023) Klein, Eledinéia Diandra Vieira; Lutz, Mauricio RamosThe present study aimed to investigate, from the teachers' perception, the learning and participation of students in the final years of elementary school in Mathematics, during the pandemic period (2020-2021), in state schools in the city of Alegrete/RS. For this case study, a questionnaire with objective and dissertative questions was elaborated. The results obtained were analyzed using the Qualitative Textual Analysis method. From the corpus analysis, two final categories were listed: participation and learning; and teacher perception: facilities and weaknesses. The results showed that the students who accessed the classes remotely or through printed material did not have an active participation. Among the reasons that contributed to the absence during synchronous meetings and the non-commitment to the delivery of activities, one can list the precarious access to internet and equipment, such as computers and cell phones, which culminated in the lack of motivation and interest of students in their studies, corroborating the learning déficit.
