Item A utilização de indicadores naturais ácido-base no ensino de ciências para alunos do 9°ano do ensino fundamental em uma escola estadual(2023-12-05) Pantoja, Raiany do Nascimento; Melo, Ana Claudia Rodrigues de; http://lattes.cnpq.br/5944321508964046; Melo, Ana Claudia Rodrigues de; http://lattes.cnpq.br/5944321508964046; Villani, Fernanda Tunes; http://lattes.cnpq.br/7767105531688783; Almeida, Luene Cristina Santos de; http://lattes.cnpq.br/7134813091920240Natural pH indicators consist of extracts or dyes extracted from vegetables, using water or ethanol. However, those responsible for enabling the color change in acidic solutions, such as vinegar and basic solutions, such as bleach, are anthocyanins. Pigments found in vegetables, which allow this change every time an acidic or basic product comes into contact with the indicator solution. Therefore, using these natural indicators to contextualize the subjects of acid and base allows the science teacher to work on the concepts in an interactive way with the students, not restricting themselves to the use of laboratory materials or substances. In this context, the present work aims to apply an experimental lesson in the classroom, using the natural indicators of red onion (Allium ceppa L.), turmeric (Curcuma longa L.) and pitaya (Hylocereus polyrhizus) to work on the subject of acid base with 9th year elementary school students. Therefore, this research is a descriptive research, with a qualitative-quantitative approach, where the experiment and questionnaires (pre-test and post-test) were applied to a 9th year elementary school class at a state public school. located in the city of Manaus–AM. The results of the analysis of the pre-test questionnaire showed that the theoretical class alone was not enough for students to learn acid and base, as students were only able to filter some parts of the subject presented in the theoretical class. Therefore, it is necessary to use practical classes with natural indicators to better understand the subject. Due to the facts mentioned, it is concluded that it is important to use the practical class with natural indicators, to contribute to students' learning about the acid and base content.Item PROUCA: uma análise sobre a inclusão digital e as práticas de ensino de ciências em Manaus(Instituto Federal do Amazonas, 2016-03-17) Araújo, Andréia Paula Ferreira de; Chaves, Edson Valente; http://lattes.cnpq.br/5983123273315301; Chaves, Edson Valente; http://lattes.cnpq.br/5983123273315301; Teixeira, Ana Frazão; http://lattes.cnpq.br/3698490801200431; Mendonça, Andréa Pereira; http://lattes.cnpq.br/0938462047218130This study aimed to analyze the PROUCA as digital inclusion policy in schools in the municipality of Manaus and its contributions to the teaching practices in science. The theoretical perspective adopted placed the importance of integrating Information and Communication Technologies (ICT) in school education and the challenges of building a science education in basic education, indicating fundamentals of digital inclusion in the Brazilian context from the educational processes taking view current theoretical perspectives and objectives of teaching and learning science at school. These perspectives have led to an analysis of the possible use of new technologies, particularly the educational laptop PROUCA, as an educational resource to renew practices in science education. As for the methodological perspective, the research was based on qualitative research, validated by literature and the use of techniques such as observation, questionnaire and interview. In field research context were contacted 12 school units of the Municipal Department of Education, and, respectively, 12 science teachers from the 9th grade of elementary school (EF), and a trainer of the Center for Educational Technology (NTE) to collect data. The collected data were analyzed based on empirical and interpretative analysis. The results showed that the inclusion of PROUCA in the investigated schools did not cause profound changes in science teaching, which collected data show that the textbook, videos and slides are the most commonplace features used in the practice of science teachers. And as there are new digital inclusion programs that provide technological resources to schools with public funds, therefore, is the disuse of existing equipment, with no due reframing and transition in the pedagogical use of such resources in the teaching practice. These findings, in addition to forming themselves into obstacles to critical and innovative use of ICT in school education, point out the importance of teacher training in digital inclusion setting. Arising from the findings was prepared a proposal for Teacher Training, as a contribution to the learning process of science teachers from the final years of elementary school, aimed at integrating the educational laptop PROUCA, with emphasis on developing educational activities supported in the use of educational technology to streamline teaching practices.
