Item Estratégias pedagógicas práticas na Educação de Jovens e Adultos: explorando o mundo das Ciências da Natureza(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-07-30) Souza, Everton de Oliveira; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167; Silva, Fred Willames Ferreira dos Santos; Fragoso, Stella Freitas de Queiroz; Nascimento, Flávia Braga do; http://lattes.cnpq.br/3585720352113766; Santos, Eduardo LimaYouth and Adult Education (EJA) is a teaching modality that aims to provide training for those who were unable to complete their studies on time. This modality mostly involves students who, for some specific reason, had to leave school. and see in this modality the possibility of training and thus entering the formal job market, many of these students had been out of the classroom for a long time, which makes the teacher's job even more difficult. The purpose of this study is to understand how the teaching-learning process and attendance can be improved through practical classes involving students from Youth and Adult Education at Escola Estadual Geraldo Melo dos Santos, in the subject of natural sciences. In classes, everyday subjects and practices are covered and new compounds are also presented that are unknown to their knowledge, but which are linked to their daily lives. Students play an active role in classes through practical activities. Furthermore, we seek to exemplify the relevance of science in everyday life, focusing on the concepts presented in the subject, which are part of the modular EJA planning.Item Estudo in vitro da atividade e eficácia fotoprotetora de extratos de camapu (Physalis angulata L.)(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-11-01) Nascimento, Keliane Francielle dos Santos; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167; Queiroz, Stella Freitas de; http://lattes.cnpq.br/5763307109586754; Souza, Davdson Luiz de; http://lattes.cnpq.br/3552801632432486Photoprotection aims to reduce skin exposure to ultraviolet (UV) radiation from the sun, helping to combat sunburn, premature aging, and even skin cancer. Sunscreens are substances capable of absorbing, reflecting or refracting UV and thus protecting the skin. The effectiveness of these products is measured through the sun protection factor (SPF), which indicates how much the photoprotective formulation is capable of protecting an individual from this radiation. Currently, the search and use of plant bioactives to protect the skin from the adverse effects of solar radiation has increased significantly, due to the diversity of organic compounds produced by plants, which have the capacity to stabilize free radicals, especially phenolic compounds, which have chromophores in its structure, which promote the absorption of radiation at wavelengths compatible with UV rays, proving suitable for the composition of solar filters, enhancing skin protection. Physalis angulata L. (camapu) belongs to the Solanaceae family and occurs mainly in the North and Northeast regions of Brazil, where it is used in folk medicine as an anti-inflammatory and in the treatment of skin problems. The present work aimed to verify the photoprotective potential of extracts from parts of the camapu plant, and to analyze the FPS behavior of a commercial sunscreen solution “FPS 30” when incorporated with these active ingredients, through in vitro analysis, of the spectrophotometric method. The results obtained demonstrated photoprotective activity of camapu flower and leaf extracts, obtaining FPS values equal to 21.38 and 7.15, respectively, at a concentration of 300 ppm, and allowed us to visualize the effectiveness of the leaf extract as a chemical sunscreen. when it comes to a photoprotective formulation. Therefore, it was concluded that the Physalis Angulata L. leaf extract associated with the photoprotective formulation enhanced the activity of the formulation, increasing its FPS by up to 40.97%, which suggests its indication for use in sunscreens, in addition to reduce production costs, knowing that natural raw materials tend to be cheaper.Item Evasão no Curso de Licenciatura em Química no Ifal - Campus Maceió: análise de dados dos alunos evadidos de 2010 a 2022(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-11-08) Silva, Raquel Venâncio da; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167; Limeira, Ana Cristina Santos; http://lattes.cnpq.br/8492241199102646; Matos, Karine Garcia; http://lattes.cnpq.br/1758509725841433This work proposes to carry out an analysis of dropout data in the Chemistry Degree course at the Federal Institute of Alagoas (IFAL), from 2010 to 2022. The approach adopted is exploratory, descriptive and quantitative, based on research conducted to investigate the causes and consequences of dropout among students of this course. The data used for this analysis will be collected from the Nilo Peçanha platform and documents provided by the Academic Records Coordination (CRA), extracted from the Integrated Academic Activity Management System (SIGAA). The research is based on understanding why the number of graduates is lower than that of entrants and identifying factors that contributed to this dropout. Furthermore, it aims at a systematic review of literature related to dropout in higher education and undergraduate education. And by combining the results of this review with specific data from IFAL, we seek to carry out a comprehensive diagnosis of the factors that influence dropout rates in the Chemistry Degree course. The joint analysis of the causes and consequences of evasion will provide a basis for developing improvement strategies.Item O processo de aprendizagem em química: análises dos instrumentos avaliativos em uma escola estadual de educação básica(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-10-13) Santos, Duciêda Narciso dos; Bastos, Alexandre Fleming Vasques; http://lattes.cnpq.br/7239157167819125; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167; Serbim, Flávia Braga do Nascimento; http://lattes.cnpq.br/3585720352113766; Brasileiro, Regina Maria de Oliveira; http://lattes.cnpq.br/4146119273576569There are several methods of evaluating the student and the evaluation instruments used and applied in an appropriate way, considering the context in which the students are inserted, as well as the teacher's methodology and conceptions adopted by him, favoring the students' teaching-learning process. This research analyzed the efficiency and performance of the evaluation instruments used by a chemistry teacher in his classes in a high school class in a basic education institution in the state network of Alagoas. This research was qualitative in a case study in which the methods of inductive approach and observational procedure were used. The research period was between March and August 2019 and the data production techniques were field notes, photos, questionnaires and document analysis. Questionnaires were applied with the chemistry teacher and students of the class and the documents analyzed were the evaluative instruments used in the classroom during the course of the research. The analyzes and discussions on the chemistry evaluation instruments were carried out based on data collected at the school, as well as on the evaluation of printed materials, which was used as a resource to prove the veracity of the research. The research was based on LUCKESI's theory, but other pedagogical theories defended by several scholars in the area were used. During the approach, some reflections on the concepts of assessment and on the assessment instruments used by the teacher can be noted. In the results of our analysis, it was evident that the teacher prioritized the evaluation focused on the traditional method, however, with some vestiges of the constructivist conception, as well as the progressive one in its pedagogical proposal. Therefore, such research helps us to understand the importance of selecting assessment instruments in an adequate way to obtain a positive diagnosis of the chemistry assessment.Item Utilização de vídeos didáticos para o tema técnicas de extração(2025-07-08) Barbosa, Cândida Caroline da Silva; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167; Silva, Leonardo Vieira da; http://lattes.cnpq.br/3401495568705461; Azevedo , Edmar Marinho de; http://lattes.cnpq.br/2213926589443334This study investigates the use of educational videos as a complementary pedagogical tool in teaching Organic Chemistry, particularly in experimental classes taught in Technical High School Chemistry courses at the Federal Institute of Alagoas (IFAL), Maceió Campus. The main objective is to address the difficulty many students face in connecting theory and practice with the content studied, including a lack of familiarity with the materials and reagents that will be used during laboratory classes. Thus, the proposal aims to promote a more dynamic (using visual resources and accessible language), contextualized (relating the content to everyday experiments), and meaningful (encouraging students' understanding and proactive role in experimental practice) teaching-learning process. Three demonstration videos of experiments included in the curriculum for third-year Technical High School students were produced and applied. All videos exclusively address extraction techniques, as this is a thematic focus defined in the research. The techniques used were: (i) solid-liquid extraction of caffeine, (ii) extraction using a Soxhlet apparatus, and (iii) acid-base extraction of Doril components. The videos were watched before the experiments. Before the practical classes and after watching and completing the practical classes, students completed questionnaires on the concepts and laboratory practices on Google Forms. The results demonstrated a significant improvement in understanding the concepts and conducting the experiments, indicating that the audiovisual resource contributes to student preparation, reducing doubts and increasing performance in the practical classes. Student evaluations of the pedagogical tool highlighted its clarity, usefulness, and appropriate structure. Therefore, the use of educational videos, integrated in a planned manner into the pedagogical process, achieved the proposed objectives and proved to be an effective tool for teaching Organic Chemistry practices, fostering knowledge construction in a more accessible, interactive, and meaningful manner.
