    Migração de docentes em química do nível estadual para o federal: estrutura e/ou salário?
    (2018) Andrade, Polyana Sanches; Soares, Márlon Herbert Flora Barbosa; Mesquita, Nyuara Araújo da Silva
    Continued training in master's and phD level is a possibility for teachers of basic education in order to improve career both in terms of theoretical deepening as in pay. From this perspective, there was a survey on the amount of chemistry teachers linked to the Education Departament of Goiás State (SEE - GO) who had access to graduate in the Chemistry Institute of UFG since the creation of the course, between 1998 to 2012. Our objective was to analyze the relationship of this teacher's continuing education with the migration / removal of this professional from the state public network, based on data provided by the graduate program in Chemistry of UFG and interviews with 16 teachers. It was possible to identify that, from 54 graduate students that were teachers of basic education of SEE-GO, only 14 remained linked to the state system after the completion of continuing education. In this context, it is evident that continuing education wasestablished as the teaching career removal element in basic education considering the current structural conditions of this career compared to the other existing professional prospects for masters and doctors in Chemistry.

    Robótica educacional no nível médio de ensino: o conceito de sistema nervoso central
    (2018) Garcia, Mara Cristina de Morais; Soares, Márlon Herbert Flora Barbosa
    The educational robotics is a pedagogical action that uses the learning of scientific concepts by the students through interaction with a robot collaboratively. The objective is to design and develop robots reusing materials to discuss biology concepts in a playful learning environment at how the educational robotics facilitates student learning the average level of education. This is a qualitative research of a case study. Participants are teenagers sixteen years on average, volunteers who participated in weekly meetings against the turn. The construction of the robot that represents the human nervous system was proposed by the students. Their participation has gone beyond the concept of the discussion and it was possible from the construction of the prototype. We note that collaboration is a major feature present in the activity. However,it is important to clarify that the cooperation of the collaboration assumptions also attended the activity. From designing the robot until its completion, we see the awakening of student interest, along with a natural increase of motivation of both the group and the teacher involved.

    O Jornal da Química como etapa inicial de abordagem problematizadora: proposta para ensino e formação de professores
    (2019-05) Pinheiro, Ricardo Silverio Gomes; Soares, Márlon Herbert Flora Barbosa
    This paper presents and discusses a project called “Newspaper of Chemistry”, whose objective was to produce an information vehicle in a language more accessible to high school students and also discuss the contributions of this project to the training of chemistry teachers. The newspaper brings themes with interdisciplinary and contextualized approach, at the same time that it brings concepts of chemistry and related areas, stimulating the student to investigate the facts and seek knowledge. The purpose of the newspaper is to initiate a problematizing approach that will be continued in another work through dialog with the students. In this project, we focus on motivating the student, taking him to the appropriation of facts and concepts and instigating the development of the critical sense. The project was planned and executed by chemistry undergraduate students during the second stage of regency, and the newspaper was distributed in the scientific event of a public school in the municipality of Iporá, Goiás. After, a questionnaire was applied to the students to identify the impact of the newspaper and if the intended objectives were achieved. The idea of the newspaper also focuses on the formation of the undergraduate chemistry student based on the reflection of its pedagogical practices, within a problematizing and constructivist approach.

    Delimitação da cultura lúdica e cultura local para proposição de jogos e atividades lúdicas: uma análise dos diferentes instrumentos de coleta de dados fundamentada em Bourdieu
    (2021) Rezende, Felipe Augusto de Mello; Martins, Laiane Pereira; Oliveira, Mariana Fonseca; Soares, Márlon Herbert Flora Barbosa
    Games have always been present in the life of human beings, however, in the Brazilian educational scope, more specifically in the teaching of Chemistry/Sciences, their insertion is recent, and still needs a lot of deepening and development of the theoretical/ epistemological nature. In this sense, it is intended from this work to discuss the importance of culture for games and recreational activities. A research uses elements of the qualitative approach, explored to obtain descriptive data that allow the identification of the cultural elements of the students involved (about 84 students with 8th grade from a public school in the interior of Goiás), both in relation to the school environment as well as familiar, as well as verifying their conception about Science, in order to answer the research question: Do the data collection instruments used in line with the Bourdieusian framework make it possible to understand the culture that students are immersed in? The results made it possible to identify the culture in which students are immersed, as well as their influence on the appropriation of scientific knowledge, since we observed even epistemological obstacles related to scientific knowledge, resulting from cultural elements appropriated by students throughout their lives.

    Jogo pedagógico para o ensino de termoquímica em turmas de educação de jovens e adultos
    (2020-08) Leite, Maria Aparecida da Silva; Soares, Márlon Herbert Flora Barbosa
    We present a pedagogical game for the initial discussion of thermochemistry concepts in two classes of students of youth and adult education at a public school in the state of Goiás. We analyze the application of a pedagogical game for adult audiences. Twenty-nine students were divided into two groups of 3rd. and 4º. periods of high school, mode EJA. The game, called the Thermochemical Path, has daily and scientific questions so that as the participants give the correct answers they move across the board. The game was performed in the classroom and allowed the students to leave a passive attitude, as it is applied using the whole space of the room. The results showed that adults have resistance to the use of games, as these are confused with leisure and opposition to work, without seriousness linked to education. In the course of the game, the students presented evolutions and reactions similar to the adolescent public in several characteristics common to the pedagogical games in the classroom.

    Uma proposta para a elaboração do jogo pedagógico a partir da concepção de esquemas conceituais
    (2021) Moraes, Fernando Aparecido de; Soares, Márlon Herbert Flora Barbosa
    This theoretical study aimed to present a proposal of how the pedagogical game should be analyzed and understood from the conception of conceptual schemes. To this end, the authors discuss the design of recreational games from the perspective of three conceptual schemes, namely: Rules, Playful Interaction and Culture. Subsequently, after characterizing the pedagogical game, according to a discussion conducted in the light of specific literature, the authors present and discuss in detail the primary scheme proposed by them to think about the pedagogical game, the Formal Education arrangement. Finally, they point out that the proposal can be used to think and develop pedagogical games not only for teaching Natural Sciences practiced in Basic Education, but in any subject linked to Formal Education.

    Jogos no ensino de Química: um estudo sobre a presença/ausência de teorias de ensino e aprendizagem na perspectiva do V Epistemológico de Gowin
    (2019-04) Rezende, Felipe Augusto de Mello; Soares, Márlon Herbert Flora Barbosa
    From the first decade of the twenty-first century, it was noticed a significant increase in the quantity of games applied to the teaching of Chemistry, however, there are games without pedagogical objectives. In this sense, a documentary analysis was used in the main periodicals of Chemistry Education/Teaching a heuristic instrument in the perspective of the Gowin’s Epistemological V, which consists of analyzing the structure and process of knowledge construction, in order to identify possible theories of teaching and learning in the game construct. The results indicated the presence of Genetic Epistemology (54,17%) and Cultural Historical Psychology (29,17%), as well as the theoretical-epistemological reference absence (16,66%). However, we identified the need for a deeper understanding of the frameworks used, since most articles explore only some elements of the theories. In this way, there sults indicate the imminence of the use of learning theories, not being possible to speak in an epistemology of the game.

    O lúdico e a formação de professores: elaboração e confecção do jogo Mega Senha da Química
    (2020) Pinheiro, Ricardo Silverio Gomes; Soares, Márlon Herbert Flora Barbosa
    This work presents the proposal of a game called Mega Password of Chemistry, whose idea was presented to students of the Chemistry Graduation during the discipline of Pedagogical Workshop II. The purpose of this resource was to contribute to the initial training of teachers of basic education, through the preparation, testing and discussion of the game with undergraduate students, as well as the impacts of the rules, the format of the proposal and how this contributed to learning and posture as future teacher. We expected the reflection of the students of graduation on their practices and of their pedagogical workshop teacher as a way to overcome the positivist view of teaching chemistry. The results showed that some students have been able to constructively criticize the presented proposal, but others still need more stimuli to reach a level of criticality sufficient to reflect satisfactorily on the teaching practices. Therefore, we identified two main groups of students: those with more developed critical sense and those with less developed critical sense.

    Movimento escoteiro e educação não formal: o uso de atividade de experimentação química em um acampamento escoteiro
    (2019-06-28) Lima, Ana Luiza do Prado; Soares , Márlon Herbert Flora Barbosa; Mesquita , Nyuara Araújo da Silva
    The present work intends to discuss some aspects about the use of games and play activities in a non-formal education environment, the scout movement. It presents a brief history about the history of Scouting in the world and brazilian scene, as well as its principles and its scout method. It addresses the definitions of formal, informal and non-formal education, characterizing them according to authors of the area, aiming to show that the activity of experimentation can be used in a space of non-formal education. This research is characterized by a qualitative approach based on a case study and observed the various possibilities of using experimental activities within the environment of non-formal education, scout movement, as a possibility to work on chemical concepts from games and play activities.

    Game over: ausência de discussões sobre feminismos e mulheres na ciência no campo dos jogos e nos principais eventos de ensino de Química/Ciências
    (2022) Lima, Ana Luiza do Prado; Rezende, Felipe Augusto de Mello; Martins, Laiane Pereira; Gonçalves, Denise de Fátima; Soares, Márlon Herbert Flora Barbosa
    The present work includes an analysis of how/if themes related to feminisms and women in Science are treated in works that use games for teaching Chemistry published in the annals of the main Chemistry teaching events in the country: ENEQ, ENPEC, as well as at the event and in the specific games magazine,respectively: JALEQUIM and RELuS. From the analysis, it is intended to outline an overview of how the area of games has dealt with such themes, as well as to promote reflections on the objects of study. The results show existing gaps in the discussions of feminisms and women in Science, as well as research on games that cover these issues and female representation in decision-making positions in event coordination. The need for spaces in scientific events and activities is highlighted, so that these discussions take place explicitly, advancing in the ludic field, understanding the potential of the game to leverage debates on gender equity and the visibility of women in Science.

    O Jogo de Realidade Alternada Curto (Short ARG) como estratégia de discussão de conceitos químicos em nível superior
    (2020-02-17) Deus, Thiago Cardoso de; Soares , Márlon Herbert Flora Barbosa
    This paper presents the application of a Short ARG built to be applied in a single class, instead of a longer interval, as it is common in strategies such as ARG. ARGs are games based on role-playing experiences that involve role playing using a particular place, in this case, two classrooms and an education lab. Whereas ARG’s characters are the participants/ players themselves, in this study, they were the Chemistry undergraduate students. The students/players were aimed of various clues and moments involving chemical concepts to find a lost student. We could notice ARG can be a teaching strategy, we mean, an alternative for conceptual discussion in the classroom as well as a diagnostic and formative assessment tool, characteristic of the use of games and recreational activities in teaching scientific concepts.

    Abordagem interdisciplinar nos capítulos de equilíbrio químico e eletroquímica em livros didáticos de Química aprovados pelo PNLD/2008/2012/2015/2018
    (2022-02-23) Leite, Maycon Batista; Soares, Márlon Herbert Flora Barbosa
    From different theoretical perspectives of interdisciplinary approach, we apprehend the one that aims the formation of the subject with critical and political consciousness of social reality. The Didactic Book is the most relevant didactic resource in the teaching chemistry in Brazil and the PNLD (National Textbook Program) presents as its main purpose, to impose a minimum quality standard on Didactic Books offered in publishing Market. We investigated which are the prospects of an interdisciplinary approach that the authors of the Chemistry Didactic Books of PNLD/2008/2012/2015/2018 present in Chemical Equilibrium and Electrochemistry chapters of their respective works. We used Bardin’s content analysis method, which provided us with elements for the constitution of three categories of interdisciplinary analysis. The research pointed out that the Didactic Books are more focused on the approach of conceptual interactions inherent to scientific Knowledge as academic and instrumental interdisciplinarity. One of the main results of this work shows that only one of the ten works analyzed reached interdisciplinarity as an understanding of contexts and issues inherent to social reality. Based on results like these, this research can contribute to the expansion of the understanding of interdisciplinarity and the qualification process of science textbooks, which implies future evaluators committed to the transformative perspective, avoiding the return of works or contents outdated by ignorance of the concept of interdisciplinarity.

    Análise de elementos corruptivos dos jogos educativos publicados na QNEsc (2012-2021) na perspectiva de Caillois
    (2022-11) Soares, Márlon Herbert Flora Barbosa; Rezende, Felipe Augusto de Mello
    The present work aims to identify possible corruptive elements in works that use games for the teaching of Chemistry/Science published in the QNEsc from 2012-2021, and to discuss how corruptions impact pedagogical games and their relationship with the philosophical references of games. The research was carried out through a document analysis, categorized a posteriori in: corruption of the agon; from mimicry; from paidia; and “absence” of corruption. There were works that corrupted paidia due to the data collection and analysis instruments used by teachers. The corruption of the agon highlighted how important and decisive the rules are in games, showing how much teachers do not understand them. 72.7% of the articles examined have corruption directly or indirectly linked to the actions of teachers, data that reinforce the need for greater theoretical, philosophical and methodological deepening of the game.

    Análise teórica e epistemológica de jogos para o ensino de Química publicados em periódicos científicos
    (2019-12-12) Rezende, Felipe Augusto de Mello; Soares, Márlon Herbert Flora Barbosa
    In recent years there has been a considerable increase in the number of publications involving the application of games for teaching Chemistry. However, such publications are not necessarily accompanied by adequate theoretical frameworks or, when used, are not directly related to teaching and learning issues. Thus, we intend to analyze a series of scientific articles from various journals between the years 2000 to 2016 in order to reveal the use of theoretical references of teaching and learning, and, from this analysis, to verify how games have been structured, in relation not only to the adopted references, but also to the students' learning. The results point to the need to discuss the role of gaming as a teaching and learning methodology, since the use of epistemological references is still very incipient, and few theoretical concepts are explored by the researchers. The vast majority of games use the epistemological references as a learning methodology, since such conceptions are listed with the purpose of confirming the concepts worked in the lectures, which has not contributed to the students' learning.

    Jogos na educação em Química: uma pesquisa bibliográfica em um periódico científico brasileiro entre 1995 e 2021
    (2022) Silva, Cleberson Souza da; Soares, Márlon Herbert Flora Barbosa
    Este trabajo de investigación bibliográficatuvo como objetivo analizar y problematizar el contenido de artículos que involucran el tema de juegos publicados en los últimos 27 años por la revista Química Nova na Escolacon el fin de señalar algunas de las principales características y peculiaridades más relevantes de tales publicaciones. Para ello, realizamos una investigación bibliográfica cualitativa en todos los números y volúmenes de la mencionada revista hasta el año 2021, en la que encontramos 37 artículos que abordaban la temática mencionada.Así, estudiamos dichos artículos a través de la técnica de análisis de contenido, que luego surgieron de las siguientes categorías: i)materias escolares con foco en el contenido abordadoen los juegos; ii)año de publicación y finalidad del juego; y iii)sección de la revista y lugar de origen de los autores y coautores de los artículos. De esta forma, con el estudio de estas categorías, fue posible comprender, en los textos analizados, los siguientes aspectos: disciplina abordada, contenido trabajado, objetivo del juego, año de publicación, sección de Química Nova na Escolaen la que se ue publicado y lugar de origen de los autores y coautores de los artículos. Por lo tanto, se constató,entre otras cosas, que la mayoría de los artículos analizados abordan contenidos tradicionales de Química de uso común en la Enseñanza Media en Brasil. Además, la mayoría de los juegos presentes en los artículos tenían como objetivo permitir un aprendizaje efectivo de Química, así como muchos de los artículos analizados provenían de grandes centros urbanos brasileños, como Goiás, Distrito Federal y Río de Janeiro, en detrimento de otras províncias como Amapá y Piauí, por ejemplo.

    E a parte da história que não é contada? Reflexões feministas sobre a história da ciência
    (2022-12-13) Lima, Ana Luiza do Prado; Soares, Márlon Herbert Flora Barbosa
    Understanding the importance of gender discussions and women’s in science, this article proposes, from a feminist perspective, to presente the history of some scientists, especially the first women accepted in western universities. The present study has a theoretical character and aims to analyze some aspects and periods of scientific construction, as a way of highlighting the process of exclusion and invisibility of scientists in the highlighted periods. It is salutary to point out that the choice for the feminist approach to the historical analysis of science was mainly due to the political, social and intersectional character of feminist movements. From the above, it was possible to verify the contradiction in the ideals of neutrality, objectivity and exemption from political/religious, on which the scientific construction was based, especially in terms of gender discussions. Faced with a scientific construction that made invisibilized and excluded scientists, in addition to having their knowledge appropriated, Science still remains within misogynistic and sogregating parameters. Therefore, this research proposes the urgency of reflections and gender discussions in scientific communities.

    Robótica educacional, ensino de Química e aprendizagem cooperativa: uma proposta para o curso de ensino superior em Engenharia Civil
    (2022-05-26) Pinheiro, Ricardo Silverio Gomes; Soares, Márlon Herbert Flora Barbosa
    Students, generally, are afraid of studying chemistry because they understand that it is a very complex area of knowledge and that it doesn’t has use in daily lives and in intended profession, which is a problem we identified in a Civil Engineering course. With this, we proposed a project in this course, based on educational robotics and educational cooperation, with the intention to form a group of students and a teacher to make a robot involving chemical knowledge in civil construction. The group made a robot, using an Arduino kit and material recycling, to identify electrochemical corrosion in concrete structures. We conducted a case study about the group through the analysis of gestures, products made, and notes in a notebook, from which two cooperative categories emerged: planning and application. From these categories, we identified that the students had their cognitive structures unbalanced by difficult situations, trials, errors, and diverse knowledge. The formation of a new equilibrium condition resulted from individual and social developments in constant interdependence, allowing the joint construction of knowledge, whose complexity increased during the process and culminated in the realization of the robot. All these aspects characterized cooperative learning.

    Classical food quality atributes and the metabolic profile of Cambuci, a native Brazilian Atlantic rainforest fruit
    (2021-06-12) Spricigo, Poliana Cristina; Correia, Banny Silva Barbosa; Borba, Karla Rodrigues; Taver, Isabela Barroso; Machado, Guilherme de Oliveira; Wilhelms, Renan Ziemann; Queiroz Júnior, Luiz Henrique Keng; Jacomino, Angelo Pedro; Colnago, Luiz Alberto
    The cambuci is a native Brazilian fruit from the Atlantic Forest biome. A soft and astringent pulp, a green color, and a sweet aroma are its main characteristics. Classical food quality attributes (fresh fruit mass, fruit height, diameters, total soluble solid, titratable acidity, and ratio) and the metabolic profile from ten accessions from three different locations were analyzed herein by analytical methods (refractometry and neutralization titration) and nuclear magnetic resonance spectroscopy. Concerning sugar content, sucrose was the predominant compound, with glucose and fructose alternating in second, depending on the accession. Citric acid was the most relevant acid, followed by shikimic and quinic acids in quite variable amounts. These three main acids vary in amounts for each accession. Ascorbic acid content emerges as an important quality attribute and makes this fruit nutritionally attractive, due to values comparable to those contained in citric fruits. The main amino acids identified in cambuci were glutamic acid individually or in comprising the tripeptide glutathione (glutamic acid, cysteine, glycine). The quality diversity of the evaluated accessions suggests the potentiality of cambuci use in future breeding programs.

    Unequivocal structural assignments of three cardanol derivatives: an experimental and theoretical approach
    (2019) Barbosa, Layla Rosario; Souza, Daiane Santana; Queiroz Júnior, Luiz Henrique Keng; Cunha Neto, Alvaro; Lima, Dênis Pires de; Beatriz, Adilson; Romão, Wanderson; Castro, Eustaquio Vinicius Ribeiro de; Lacerda Júnior, Valdemar
    Cardanol was obtained by vacuum distillation of ‘‘cashew nut shell liquid’’ (CNSL). Cardanol is a by-product of cashew production and a building block for chemical synthesis; cardanol and its derivatives can be used for different types of applications. Three of these compounds are the subject of the present NMR study and theoretical comparison. 1H and 13C NMR signals were assigned using 1D and 2D NMR experiments. The DFT/B3LYP method using the cc-pVTZ basis set was employed for the calculations of the 1H and 13C NMR chemical shifts (δ). The obtained data were used as an auxiliary tool for unequivocal assignment of all 1H and 1³C NMR signals. For these compounds, the adopted theoretical model was sufficient to obtain a good description of the chemical shifts.
