Item A experimentação no ensino de Química: análise de uma proposta de sequência didática para o ensino do conteúdo de metais pesados(2024-09-27) Lima, Isabela Januario de; Silva, Suely Alves da; http://lattes.cnpq.br/3497194749381919Chemistry and the knowledge it provides are extremely important for humanity since its beginning. Learning it provides the students comprehension about the most variable chemical transformations that happen around us. Teaching Chemistry can be challenging for various teachers that have troubles in getting attention from its students for this science, since it has very abstract characteristics and of tough comprehension. In this regard, practical pedagogics are needed to help catch the students’ attention on this science, and one way of achieve that goal is by practical experiments. The general goal of this research was to analyze a didactical sequence utilizing the experimentation as a methodology strategy for the teaching about the Heavy Metals. The utilization of practical activities in the teaching of Chemistry shows as a good strategy to simplify and enthrall the students in the process of learning so that they can articulate the theoretical concepts with practical experiments. This research shows the analysis of a didactical sequence about of using practical experiments when teaching about Heavy Metals. It shows the benefits that practical activities brought while learning the subject, as well the development of scientific abilities. The acquired data were analyzed in an articulated way along with the authors of the theoretical foundation under a qualitative perspective. The tools utilized were two questionnaires, one applied before the experimental activity, and a problem situation to conclude activities carried out afterwards. The research brought many positive outcomes, as a bigger participation of the students and a better comprehension of the same about the Heavy Metals and their characteristics. The engagement and curiosity about this specific subject and about clothes questions that involves chemistry in the experimental part of this science. In conclusion the experiment is one strategy that provides an improvement in the process of teaching and contributes to a bigger engagement of the students in the class, stimulating the curiosity of this science.Item Uma proposta de experimento investigativo com materiais de baixo custo para ensino e aprendizagem de eletroquímica(2023-09-05) Vasconcelos, Rodrigo da Silva; Freitas, Kátia Cristina Silva de; http://lattes.cnpq.br/5859266863241551This work proposes a teaching-learning sequence for classes in high school addressing contents, concepts and skills related to electrochemistry aiming to complement traditional teaching classes with the implementation of experimental procedures with low-cost materials. It should be noted that because it is a broad, complex and important content, greater attention should be paid to the way it is taught. During the present work, it was sought to evaluate whether a didactic sequence divided into five stages with the use of demonstrative and investigative experimentation can improve the teaching-learning process of contents and skills, through the proposition of experimental procedures in constructions of electrochemical cells and the qualitative analysis of the contents and concepts emerged at the end of the didactic sequence. It is concluded that the sequence proposal can contribute positively to the development of knowledge because, at the end of the research, some substitutions and complementations of initial conceptions related to electrochemistry are perceived.Item A importância da experimentação no enfoque demonstrativo no processo de ensino-aprendizagem do conteúdo de eletroquímica de forma contextualizada(2023-04-17) Silva, Suelani Marques da; Silva, Suely Alves da; http://lattes.cnpq.br/3497194749381919The lack of contextualization from the historical, cultural, economic and technological point of view, as well as the lack of experimentation in the classroom, often due to lack of structure and laboratory in schools, have been some of the many problems faced in teaching chemistry. Thus, the use of contexts that interact with the student's reality can significantly contribute to the learning of scientific concepts. Therefore, the objective of this research was to analyze the use of experiments with a demonstrative approach in the teaching and learning process of electrochemistry in a contextualized way. The development of this research took place in the third year class of a reference school located in Paulista/Pernambuco, with the participation of 35 students. The didactic sequence used was divided into 5 moments, distributed in 5 classes and three modalities used as data collection instruments were applied. When the observers' responses occurred, there was a high rate of correct answers in questions related to technological, social and environmental contexts, as well as in relation to content and electrochemistry, however, most arguments were not present about the scientific content. The obtained results proved the importance of working the electrochemistry content from a contextualized practice. The results obtained highlight the importance of working with the electrochemical content from the demonstrative approach in a contextualized way, showing a relevant alternative to help the understanding of the content by the student in contexts that influence the reality of the students, such as technological, social and cultural conceptions that brings meaning to the learning of scientific concepts.Item Experimentação utilizando como contexto alimentos e alimentação: uma abordagem para o ensino de Química(2023-05-12) Oliveira, Gabriela Alves de; Freitas Filho, João Rufino de; http://lattes.cnpq.br/9252404584350850; http://lattes.cnpq.br/2277869864110720Chemistry classes are seen by many students as boring or difficult to understand, generating disinterest and discouragement in the study of this science. One way of reversing this situation is the insertion of contextualization and experimentation in chemistry teaching, as a way of bringing scientific knowledge closer to students' daily lives, as well as arousing greater interest from experimental activities. Having foods and feeding as this focus, it emerges as the main theme for an experimentation activity, since they are treated at all levels of education and are part of everyone's life. That way, this study was carried out in a municipal school in Recife - PE, with students from the 6th to the 9th grade of elementary school and had the general objective: To develop and carry out an experimentation activity in the teaching of chemistry, seeking to promote the awareness of students of a school in the city of Recife on the quality of food and healthy eating practices, in order to contextualize chemical knowledge with everyday life. The research, classified as qualitative and of the pedagogical intervention type, was carried out with 22 students participating in the Science Club of the Science and Technology Laboratory of the school, in three meetings, each lasting 60 minutes. In the first methodological moment, the students' previous conceptions about the concepts of foods, healthy eating and food quality were collected; In the second stage, a dialogic expository class was held, seeking to introduce students to the chemistry present in this theme; And in the third and last stage, the importance of food quality was discussed and an experimental activity was performed on the physical-chemical analyzes used to attest to the quality of the milk consumed by the students. Data collection was made from questionnaires applied during the pedagogical intervention, as well as observations of the class during classes. It was noticed with the answers to the questionnaires, that at the beginning of the activity, most students did not have knowledge about the composition of foods, but that in general they had a balanced diet due to the number of meals eaten in the full school. During the execution of the activity, especially in the experimentation part, the class showed a lot of interest in studying the subject and because it was something that was part of their daily life, there was great participation and acceptance of the class, thus concluding that contextualization and experimentation are essential and in fact great allies for the teaching of chemistry. In the end, it was found that there were advances in the answers given by the students and it is hoped that with this activity, the participating students have awakened to issues related to healthy eating, food quality and how chemistry is present in the most diverse situations around us,not just limited to what is studied in the classroom.Item Experimentação investigativa em eletroquímica: análise das contribuições para a formação de licenciandos em Química(2022-09-28) Santos, Jeibson Joaquim dos; Freitas, Kátia Cristina Silva de; http://lattes.cnpq.br/5859266863241551; http://lattes.cnpq.br/3779449247384247
