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.Item Avaliação das atividades lúdicas nos PPCs dos cursos de licenciatura em química em instituições públicas(2025-07-01) Silva , Janaina Miguel da; Ferreira Junior , Jésu Costa; http://lattes.cnpq.br/5859354241648167; Nascimento , Flávia Braga do; https://lattes.cnpq.br/3585720352113766; Nogueira , Fred Augusto Ribeiro; https://lattes.cnpq.br/9784216306395155The training of Chemistry teachers faces significant challenges due to the abstract nature of the subject matter, requiring the adoption of innovative pedagogical methodologies. This study aims to analyze and evaluate the inclusion and implementation of playful activities proposed in the Political-Pedagogical Projects (PPCs) of undergraduate Chemistry programs at public institutions in Alagoas, focusing on the impact of such practices on initial teacher education. The research highlights the use of playful strategies as a pedagogical approach capable of making Chemistry teaching more dynamic, meaningful, and conducive to the development of essential professional skills. Active teaching methodologies, which place students at the center of the learning process, are discussed as effective tools for encouraging participation, autonomy, and critical thinking. The findings indicate that, despite widespread recognition of the benefits of playful activities, their implementation still faces obstacles such as resistance from teachers and students, lack of specific training, and scarcity of appropriate pedagogical resources. However, the analyzed experiences show that, when well-planned and executed, these activities foster greater student motivation, enhance the understanding of abstract concepts, and support the development of socio-emotional skills such as creativity, collaboration, and teamwork. The study proposes a more structured integration of active methodologies into the curriculum, along with ongoing teacher training, in order to promote more engaging and effective teaching practices. By incorporating playful strategies into teacher education programs, it is expected that future Chemistry teachers will be better prepared to face contemporary teaching challenges and deliver a higher-quality education.Item O ensino de química para deficientes visuais: produção de caderno experimental como ferramenta colaborativa para aulas de química(2025-06-30) Silva, Arali Meireles Lima; Bernardo, Francyelle Moura de Oliveira; http://lattes.cnpq.br/8677739496868550; Ana Carolina Fradique de Lyra; Lyra, Ana Carolina Fradique de; http://lattes.cnpq.br/5481668229830134; Nascimento , Flávia Braga do; http://lattes.cnpq.br/3585720352113766Item Storytelling como recurso didático para o ensino de oxidação e eletrólise no ensino médio(2025-05-28) Santos, Jeane Albuquerque dos; Nogueira, Fred Augusto Ribeiro; http://lattes.cnpq.br/9784216306395155; Santos , Eduardo Lima dos; http://lattes.cnpq.br/0426360378881187; Silva, Leonardo Vieira da; http://lattes.cnpq.br/3401495568705461The difficulty high school students have in understanding technical chemistry content, such as physical chemistry and electrochemistry, highlights the need for innovative teaching methodologies that make learning more accessible and meaningful. Given this scenario, this study used storytelling as a teaching strategy for teaching chemistry, with the aim of promoting greater engagement, contextualization, accessible language, and knowledge retention. To this end, the specific objectives defined were to analyze the recurrence of physical chemistry and electrochemistry content in the ENEM (2020-2024) exams, develop and apply pedagogical proposals using narratives, and evaluate the impacts of this methodology on the teaching and learning processes. The research had a qualitative, quantitative, and exploratory approach, structured in three stages: statistical analysis of the chemistry questions on the exam, bibliographic review on active methodologies and storytelling, and elaboration of a pedagogical proposal. Two activities were developed: “Statue Oxidation” and “Battery Storytelling: Improper Disposal”, which contextualize chemical concepts through interactive and interdisciplinary narratives. The results revealed that the use of the narrative resource favors the understanding of the content, stimulates student participation and contributes to the development of critical and reflective skills. The strategy was aligned with the guidelines of the National Common Curricular Base (BNCC), although its implementation still faces challenges related to teacher training and school infrastructure. It is concluded that the narrative proposal is a promising approach for teaching chemistry, and its application in different educational contexts is recommended.Item O processo de ensino-aprendizagem de química na Educação de Jovens e Adultos(2025-02-13) Silva, Juliana Lima; Brasileiro, Regina Maria de Oliveira; http://lattes.cnpq.br/4146119273576569; Varela, Simone; http://lattes.cnpq.br/8249879413860593; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167This Final Course Work aims to analyze the methodologies used to teach chemistry that favor the learning of students in Youth and Adult Education (EJA). It seeks to answer the research problem: what methodologies do chemistry teachers use for EJA students' learning? Its general objective is to improve the quality of teaching for EJA students by focusing on methodologies that use everyday life to contextualize the subject of chemistry in order to lead EJA students to understand the subject of chemistry in a clear way. This work uses bibliographic research as its methodology. Having a qualitative character, a survey of the texts that served as data for the bibliographic research was carried out, with filters in the search: open access, article, period from 2019 to 2024, national productions. The results show that teaching chemistry in EJA faces specific challenges, given the diversity of experiences and needs of students. The traditional approach proves to be ineffective for this audience. Active, contextualized and dialogic methodologies, which value students' prior knowledge and connect chemical content to their daily lives, have shown to be more promising. The importance of teacher training is highlighted, emphasizing the need to prepare them to deal with the particularities of this audience and to use innovative and inclusive methodologies, valuing dialogue and pointing it out as an effective strategy to make chemistry teaching more meaningful and engaging for EJA students.Item A magia das cores na experimentação: utilizando indicador natural para ensinar conceitos de química.(2025-02-11) Santos, Leôncio Silva; Ferreira, Danielle da Silva; Silva, Merylane Porto da; http://lattes.cnpq.br/4940334471477236; Nascimento, Flávia Braga do; http://lattes.cnpq.br/3585720352113766The objective of this final project is to study the application of a practical experiment that uses red cabbage as a natural pH indicator in chemistry. The term pH is essential in chemistry and is necessary to understand the acidity and alkalinity of solutions. However, students often have difficulty understanding these abstract concepts. This is why education should be more dynamic and interactive. Red cabbage was chosen for this study because it has the ability to change color at different pH levels, making it an easy-to-use and accessible visual resource. The experiment consists of making cabbage extracts and using them to test the pH of various solutions allows students to observe the color changes that reflect changes in pH. The results of the questionnaires and observations administered to the students show that the practical activity arouses curiosity and theoretical understanding of pH. Students reported that they retained more information and were able to apply the ideas to everyday situations. This dissertation emphasizes the importance of incorporating hands-on experiences into chemistry teaching and shows how the use of natural indicators such as red cabbage can improve learning, democratize access to educational resources, and encourage students to experiment. The research findings indicate that this method can be a valuable pedagogical tool that helps create more meaningful and engaging learning.Item Caracterização físico-química da própolis marrom e geoprópolis no nordeste alagoano, Brasil(2024-10-24) Moura, Orlando Francisco da Silva; Freitas, Johnnatan Duarte de; http://lattes.cnpq.br/4999402869058858; Sousa, Jonas dos Santos; http://lattes.cnpq.br/3193945439772961; Marins, Élida Fernanda Cavalcanti; http://lattes.cnpq.br/5169972835746750; Silva, Cristian Bernardo da; http://lattes.cnpq.br/8903978116383659The brown propolis, produced by bees of the species Apis mellifera, and geopropolis, generated by Melipona scutellaris, are widely recognized for their significant bioactive properties, such as antimicrobial, antioxidant, and anti-inflammatory activities. This study aimed to characterize the physicochemical properties of geopropolis from the municipality of Maceió and brown propolis from the municipality of Pilar. The samples underwent extraction by maceration and Soxhlet methods, followed by detailed analyses of wax content, loss on drying, ash content, and soluble solids. The results showed that brown propolis exhibited an average mechanical mass of 29.65% in the Soxhlet extraction and 56.9% in maceration, while geopropolis had mechanical mass contents of 75.73% and 75.08%, respectively. The wax content in propolis was 22.44% (Soxhlet) and 31.20% (maceration), exceeding the legal limit in maceration. The loss on drying was 5.81% for propolis, within standards, while geopropolis showed 4.56%. The ash content was 1.87% for propolis and 65.22% for geopropolis, reflecting a higher amount of inorganic material in the latter. The quantification of phenolic compounds revealed 2.02% for propolis (Soxhlet) and 2.80% (maceration), while geopropolis contained 2.74% and 2.22%, respectively. Total flavonoids were 0.011% (Soxhlet) and 0.046% (maceration) for propolis, and 0.039% (Soxhlet) and 1.33% (maceration) for geopropolis. Antioxidant activity, evaluated by the DPPH method, was 31.94% for propolis (Soxhlet) and 73.81% (maceration), while geopropolis showed 75.82% (Soxhlet) and 86.11% (maceration). Additionally, the analysis of volatile organic compounds conducted by Gas Chromatography coupled with Mass Spectrometry revealed the presence of 66 compounds in brown propolis and 48 compounds in geopropolis. The diversity of volatile compounds, including esters, terpenes, and phenols, highlights the potential of these substances for therapeutic and industrial applications. These results indicate that both propolis and geopropolis possess high levels of bioactive compounds, marked by their strong antioxidant activity, suggesting considerable therapeutic potential. The physicochemical characterization of these substances is of great importance for the municipalities of Pilar and Maceió, as it enhances local natural resources and opens opportunities for the development of apicultural products with industrial and medicinal applications. Additionally, this research contributes to the strengthening of beekeeping in the region, promoting sustainable practices and valuing local culture within a context of conservation and health.Item Avaliação dos PPCs de instituições de ensino superior no estado de Alagoas na disciplinas de formação tecnológica no curso de licenciatura em química(2024-10-25) Silva Júnior, Edson Caetano da; Morilla , Demétrius Pereira; http://lattes.cnpq.br/5723725916193842; Santos, Eduardo Lima dos; http://lattes.cnpq.br/0426360378881187; Soares, Janaina Gomes; http://lattes.cnpq.br/9254836310407411; Azevedo, Edmar Marinho de; http://lattes.cnpq.br/2213926589443334his study aims to analyze the integration of Digital Information and Communication Technologies (ICTs) in Chemistry education, focusing on the importance of these technologies in teacher training and pedagogical practices for teaching this subject.

Due to their pharmacological potential, they have been the subject of several studies. The species Cecropia pachystachya, which belongs to the Cecropiaceae family and is popularly known as embaúba, can be cited as one of the most studied species due to its proven therapeutic properties as well as its chemical compounds. The aim of this study was to evaluate the antioxidant activity of the ethanolic extract of Cecropia pachystachya leaves and to quantify its phytochemical profile. To this end, after obtaining the crude ethanolic extract of Cecropia pachystachya leaves, tests were carried out to quantify phenolic compounds using the Folin-Ciocalteau method and quantify flavonoids using the reaction with aluminum chloride, as well as evaluating antioxidant activity using the DPPH free radical capture method. The results showed quantifications of 686.41 and 509.34 μg/mL for phenolic compounds and flavonoids, respectively. These results were higher than those found in the literature. And the minimum concentration that showed a 50% reduction in free radicals was 433.70 μg/mL. According to the literature, this result can be explained by the quantification of bioactive compounds present in the species. In view of the above, it was possible to conclude that Cecropia pachystachya can be considered a therapeutic alternative for the pharmaceutical and cosmetics industries.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 Sesnsibilização de pós de TIO2 modelados por esferas de látex para aplicação em células solares(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2018-08-15) Silva, Antony Ernesto dos Santos; Barros Filho, Djalma de Albuquerque; http://lattes.cnpq.br/9259521036882745; Freitas, Johnnatan Duarte de; http://lattes.cnpq.br/4999402869058858; Costa, Alex Emanuel Barros; http://lattes.cnpq.br/2231272728491909; Silva, Antonio Osimar Sousa da; http://lattes.cnpq.br/5289388662589522The world's energy supply is derived from the burning of fossil fuels, in particular oil, producing greenhouse gases, which causes damage to the ozone layer, in addition to changing the planet's temperature and to threatening life in general. Therefore it is necessary to use natural, renewable energy sources, such as solar energy for example. Brazilian Northeast has one of the highest rates of solar radiation in the country, which makes it feasible to use solar energy in this region. Thus, this work has the objective of presenting the formation of Dye Sensitized Solar Cells (DSSCs), with semiconductor films made of titania (TiO2) powders, templated by latex spheres. These films are sensitized by ruthenium dye complexes, which makes their use relatively applicable in the absorption of solar energy. It will be possible later to convert solar energy into electric energy through the photovoltaic effect. TiO2 powders used in this work were obtained from two latex bead molds: sedimented powders and solvent controlled evaporation films (ECS). The results show that TiO2 modeling by both molds was not efficient, because the film presented a compact surface, decreasing the porosity of titania film. This can lead to a non-anchoring of the dye sensitizer on the surface of the semiconductor film and also poor penetration of the redox pair therein and the final result is a low absorption of sun light by the film. Another factor to decrease titania sensitization was the presence of carbon in during densification process, since the carbon was not completely removed. Carbon makes a surface layer that competed with the sensitizing dye during its anchoring in semiconductor film and increased the recombination of electron-hole pair. It is concluded that topography of látex beads and the presence of carbon during calcination of TiO2 powders made it difficult to absorb light when sensitized, becoming a challenge its application in DSSCs. An alternative to solve this problem is the use of TiO2 powders when obtained through templates coated on microscope glass slides by ECS technique. This will ensure an efficient porosity of titania filmsItem Desenvolvimento de sensor eletroquímico baseado em eletrodos impressos de carbono, modificados com Ácido Polixanturênico para detecção da Afloxitina B1(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2019-12-05) Silva, Jéssica da Conceição da; Lima, Phabyanno Rodrigues; http://lattes.cnpq.br/9334426018309756; Cavalcante, Sarah Kelly Melo; http://lattes.cnpq.br/0820477133147241; Silva, Jailson dos SantosIn the present work we describe the development of an electrode that uses xanturenic acid (AX) for the first time as an electrochemical probe, through a simple and efficient Aano-activated, nanomaterial modified carbon printed electrode immobilized with aptamers for the detection of aflotoxin. B1 (AFB1). The sensor surface was characterized by voltammetric techniques such as differential pulse voltammetry (VPD) and cyclic voltammetry (VC), which were used to study the behavior of modified electrodes, to optimize experimental parameters and obtain kinetic parameters. as a study of speed and pH. The electroactive species, quinone / hydroquinone, was electrogenerated in situ on the modified nanomaterials and AX electrode after cycles in the potential range between 0.5 and -1.0 vs. Ag at first sweep in 0.1 mol L-1 phosphate buffer (pH 5.5) with sweep rate of 50 mV s-1. After the activation process, the potential range around the redox quinone / hydroquinone pair was selected and the voltammograms were recorded at different speeds (5-20 mV s-1), then aptamer immobilization was performed, applied with the intention of to test the electrocatalytic activity for AFB1 oxidation. In addition, the electroactive species generated on the electrode surface showed inhibition against the immobilized aptamer when reacting with AFB1, causing a charge retention. Thus, from the results obtained the electrochemical aptensor developed showed a promising alternative to be applied in tests with real samples.Item Determinação de ácido ascórbico: um sensor eletroquímico à base de pasta de carbono com 4-nitroanilina adsorvida em silica gel modificada(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2019-12-05) Santos, Monik Tamíres Silva; Cavalcante, Sarah Kelly Melo; http://lattes.cnpq.br/0820477133147241; Lima, Phabyanno Rodrigues; http://lattes.cnpq.br/9334426018309756; Cavalcante, Sarah Kelly Melo; http://lattes.cnpq.br/0820477133147241; Silva, Jailson dos SantosThe present work describes the development of a multiple wall carbon nanotube paste electrode (MWCNTPE) based on 4-nitroaniline (4NA) adsorbed onto silica gel modified with zirconium oxide (SZ) to detect ascorbic acid (AA). The sensing surface was characterized by Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and Infrared Spectroscopy (FTIR). The electroactive species, hydroxylamine / nitrous (R-NHOH / R-NO), was electrogenerated in situ from 4Nitroaniline after cycling in the potential range between 0.5 and -1.0 vs. Ag / AgCl in the first scan in 0.1 mol L-1 PBS buffer (pH 7.0) with a scanning rate of 0.02 Vs-1. The modified electrode showed efficient electrocatalytic activity against the oxidation of ascorbic acid in 0.3 V vs. Ag / AgCl. Electrochemical measurements including Cyclic Voltammetry (VC) and Chronoamperometry were used to study the behavior of the surface of the modified electrode used. These techniques were used to optimize the experimental parameters. Thus, under optimized conditions, the sensor presented a linear response range of 0.5 - 3.0 μmol.L-1, LD (0.15 μmol.L-1), LQ (0.48 μmol.L-1) and sensitivity of 7.60 (mA.L.mmol-1) adding to the sensor positive factors in sensitivity and selectivity. This sensor was applied for the amperometric determination of AA in food samples. The results were consistent with those obtained with the standard titration procedure.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 O projeto de vida como componente curricular no Ensino Médio do estado de Alagoas: autonomia, protagonismo, e o pensamento crítico(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-03-27) Lima Neto, Isnar Lopes de; Serbim, Flavia Braga do Nascimento; Limeira, Ana Cristina dos Santos; Silva, Jéssica da ConceiçãoThe reform of the new secondary education presents as the central axis of its reflections youth protagonism, autonomy, critical awareness, flexible curriculum, and the dichotomy between work and school. The objective of the study is to understand how the life project discipline promotes autonomy, protagonism, critical thinking, and prepares students for the world of work in state education networks in high school. For this, the method used consisted of surveying the official documents available on the website of the Alagoas State Department of Education that support the implementation of the life project curricular component, analyzing the material through a qualitative approach. The investigation reveals a major challenge of the new high school model, to guarantee the comprehensive training of students, prioritizing the development of socio-emotional skills, and at the same time responding to the desires of young people, guaranteeing qualification for the world of work and the continuity of studies, often failing to have a solid theoretical pedagogical basis in the development of the material. Finally, it can be understood that the life project requires critical reflection in relation to the proposals made in its formulation, looking at the context of secondary education reform, as it is an emerging discipline that does not derive from a disciplinary field or specific area of knowledge.Item Sensores eletroquímicos para determinação de agroquímicos: revisão de métodos empregados para o herbicida Metribuzin(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-12-04) Mariano, Nicholas Emmanuel Constantino; Souza, Antonio Albuquerque de; http://lattes.cnpq.br/7344135285199504; Freitas, Alan John Duarte de; http://lattes.cnpq.br/7222112856028905; Lopes, Cleylton Bezerra; http://lattes.cnpq.br/4000861323429729The increasing demand for food has led to the development of various control control agents to increase crop yields. And due to the population increase, it became necessary to use these agents to meet food demand. However, its excess causes harm to human health and the environment. Metribuzin (MTZ) is one of the most common herbicides for the control of organic weeds, however, due to its increase and excess, it is necessary to monitor and determine this herbicide, which is essential to reduce risks to the environment and human health. One of the alternatives that has been growing for its determination is the use of electrochemical sensors that consist of translating the chemical information of certain analytes into measurable electrical signals (STRADIOTTO; YAMANAKA; ZANONI, 2003; KIMMEL et al., 2012). These devices can have high sensitivity, are easy to prepare and have a relative low cost. They can also be characterized by details, as it is possible to analyze molecules of environmental interest (ŠVORC; RIEVAJ; BUSTIN, 2013), foods (PACHECO et al., 2015). In this work, some literary sensors were selected in which the authors provided the construction of these electrochemicals for the determination of Metribuzin using different mediators where: (Lima, 2009) used carbon paste/Nujol to determine the MTZ; (Fatah, 2022) used NTCPM/MIP-EPC to determine the MTZ; (Moreno, 2009) used a Bismuth Film Electrode for determination; (Ranganatha, 2022) used CS-PC/BPE/ECV to determine MTZ; (Yamuna, 2022) used NTO-eGR/ECV to determine MTZ.Item O lúdico na aprendizagem de vidrarias de laboratório de química na Escola Estadual Dr. Antônio Gomes de Barros(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2018-06-08) Silva, Eronildo Ferreira da; Freitas, Alan John Duarte de; http://lattes.cnpq.br/7222112856028905; Freitas, Johnnatan Duarte de; http://lattes.cnpq.br/4999402869058858; Lira, Lidiane Evangelista; http://lattes.cnpq.br/7428353456925450; Silva, Kleyfton Soares da; http://lattes.cnpq.br/9040257542465304; Morilla, Demetrius Pereira; http://lattes.cnpq.br/5723725916193842; Sousa, Jonas dos Santos; http://lattes.cnpq.br/3193945439772961; Soares, Janaína Gomes; http://lattes.cnpq.br/9254836310407411This research aimed to approach an educational methodology that differs from traditional teaching with students of the 1st year of high school in a state public school, located in the municipality of Novo Lino, in the state of Alagoas, and evaluate learning outcomes by applying the game didactic "LEARNING GLASSES", in which it presents the main materials and laboratory glassware, also trying to help students become more interested, attentive and participative. For this construction was used the case study, which approached the playful as methodology in teaching and learning chemistry. Throughout the study and the findings, it was possible to confirm that it is feasible to approach a different methodology when applied correctly in teaching and learning.Item O Youtube e o ensino de Química: uma análise dos canais educativos como ferramenta de apoio ao docente(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-11-07) Oliveira, Julliany Correia de; Nascimento, Flavia Braga do; http://lattes.cnpq.br/3585720352113766; Limeira, Ana Cristina Santos; http://lattes.cnpq.br/8492241199102646; Ferreira Júnior, Jésu Costa; http://lattes.cnpq.br/5859354241648167This study was motivated by the COVID-19 pandemic scenario, which boosted the search for effective educational alternatives. Given this context, we wondered whether YouTube channels could be used as a support tool for teachers in chemistry teaching, complementing face-to-face teaching and enabling the review and deepening of content, given that this platform is easy to access and widely used. by the current generation. Our general objective was to analyze whether video lessons from YouTube chemistry channels are relevant for teaching and whether these channels can be used by teachers as an aid in classes. Furthermore, our specific objectives were: to identify the main channels, evaluate the quality of the content and identify the limitations of this resource. This is a quantitative bibliographic research, in which the methodology adopted consists of five distinct stages. First, the number of channels was defined, followed by the collection of data considered permanent and data that is constantly updated on the platform. Finally, we describe the results and analyze the data obtained during the research. It was found that in fact, YouTube can be a valuable tool to support teachers in teaching chemistry. This platform represents an effective bridge between the educator and the student, presenting itself as an enriching resource, capable of complementing traditional content and stimulating students' interest in the subject. In this way, this research can also serve as inspiration for future projects, and to improve the use of this tool to support chemistry teaching, which is rich in possibilities and very promising for contemporary education.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.
