Implicações formativas para a atuação de professores de química da educação básica em relação à temática radioatividade
(2025) Nunes, Luclécia Dias; Mesquita, Nyuara Araújo da Silva
The training of Chemistry teachers in Brazil has been researched for a few decades and studies point out to training gaps that reverberate in teaching, especially in basic education. One of the contents covered in this step and which is part of the high school curriculum is radioactivity, which is related, among other things, to radiological and radioactive accidents that occur around the world. Thus, this research sought to investigate how the training provided to Chemistry undergraduates in the state of Goiás is in relation to the subject of radioactivity, since in 1987 a radiological accident occurred in Goiânia with a Cesium 137 source. This is a qualitative research, data were collected via questionnaire and the analytical technique used was discursive textual analysis (ATD). The results showed that due importance was not given to the radiological accident, since there is evidence of training gaps in relation to the topic of radioactivity in Chemistry degree courses in the state of Goiás, where the accident occurred, and the contents on radioactivity are either not addressed, or the approach is superficial. This fact directly impacts the teacher’s performance in basic education, when working on this content with their students.
Da Base Nacional Comum Curricular às Diretrizes Curriculares do Estado de Goiás: o caminho construído para a educação ambiental no Ensino Médio
(2025-12) Oliveira, Ana Lúcia Campos de; Silva, Iara Custódio da; Godoi, Nicole Marques; Mesquita, Nyuara Araújo da Silva
Environmental Education (EE), supported by Law 9.795/1999, is crucial for the critical education of Revista Didática Sistêmica, ISSN 1809-3108 v. 27, n. 2, p. 82-95, jul./dez. (2025) 83 young people in the face of socio-environmental challenges. The aim of this research was to carry out a documentary analysis to understand how environmental perspectives are included in the following basic education documents: Curriculum Document for Goiás - High School Stage (DC-GOEM) and the National Common Core Curriculum (BNCC). We sought to identify how the environmental perspective is included in the High School stage, more specifically in the area of Natural Sciences and their Technologies. According to the data collected, it was possible to verify the low incidence of terms related to environmental education in the BNCC, with the Pragmatic macro-trend being more predominant, which is also the case in the DC-GOEM. The critical macro-trend, on the other hand, appears timidly, as it is essential for forming conscious citizens. This shows the need for a curriculum review, with a view to broadening the inclusion of the environmental perspective in these documents.

(2025) Machado, Ana Paula Amaral de Freitas; Nóbrega, Lorrana Nara Naves; Benite, Claudio Roberto Machado
The purpose of this article is to analyze the state of the art regarding theses and dissertations on the identification and referral of students with giftedness or high abilities in the field of Natural Sciences. The study aims to map the procedures adopted, examine the types of identification instruments that have been employed for this purpose, and identify gaps in the literature that may guide future research and educational practices. To this end, we consulted research published in the Capes Theses and Dissertations Database, from 2005 to 2024. The data were analyzed based on the following categories: productions per year, identification of high abilities/giftedness, Natural Sciences area, and identification/indication instrument. The results revealed 36 studies focused on the identification or indication of students with high abilities/giftedness. Specifically in the Natural Sciences area, 9 studies address the topic of high abilities/giftedness, of which only 2 are dedicated to research related to the identification or indication of students with characteristics of high abilities/giftedness in Natural Sciences. This scenario evidences that the topic is still little discussed, giftedness relevance of bringing it to the scientific debate.

Robótica educacional e Educação do Campo: proposta de medidor de temperatura e umidade para estufas no plantio de hortaliças
(2025) Pereira Júnior, Carlos Antônio; Silveira, Kelly Rita Ferreira dos Santos; Oliveira, Higor Júnior de; Soares, Márlon Herbert Flora Barbosa
This study addressed the planning, construction, and implementation of a robotic device for reading temperature and humidity inside handmade greenhouses from the perspective of Paulo Freire’s liberating education. The proposal aimed to discuss the potential of working with educational robotics in the context of rural education, focusing on building scientific concepts. A qualitative research methodology was employed, following a case study approach. The main outcome identified was an interdisciplinary perspective, in which it was possible to analyze the knowledge required for the planning and construction of the robotic prototype, as well as the knowledge and concepts related to building handmade greenhouses, and finally, the knowledge concerning vegetables within the field of agronomy. Thus, we observed the integration of mathematical, physical, chemical, and agronomic knowledge to solve various problems encountered throughout the different phases of the project. Ultimately, we understand that Educational Robotics can serve as a guiding element for transformative pedagogical practices in Rural Education, as rural subjects not only become protagonists in the construction and production of knowledge but can also use technology to transform their community realities, starting with the school.
Educação sexual e de gênero: diálogos a partir da formação inicial de professores(as) de química
(2025-12) Camilo, Washington Marcos; Soares, Márlon Herbert Flora Barbosa
This article is part of a master's research project that took place during the pandemic. We held a focus group with chemistry undergraduate students who were studying didactics at a federal university in Goiás with the aim of analyzing the discourses on gender and sexuality that circulate among chemistry undergraduates and based on their comments, bringing together the theoretical/conceptual social studies of the body, gender and sexuality in the training of chemistry teachers. The statements were separated into categories of analysis based on the discourse analysis technique. It is very common for conservatism to resort to biological and chemical justifications to silence any movement towards sexual and gender education from a critical and diverse perspective, so that these universal subjects remain in positions of privilege. We advocate an education outside of the hegemonic molds, since those offered by the church and the family and by traditional science do not take into account the dynamics of these crossings. We want to contribute to a more plural teacher training that thinks about all the bodies involved in the teaching-learning process. To this end, the debate needs to be included in the initial training of teachers, as well as in the curricula of degree courses, so that these education professionals can be better prepared to deal with the intersections of gender and sexuality.
O ensino de botânica em um contexto bilíngue (LIBRAS-português): a tradução intersemiótica na construção do conhecimento científico
(2025) Rodrigues, Gustavo Fernandes; Pereira, Lidiane de Lemos Soares; Benite, Anna Maria Canavarro
In this article, we analyze how intersemiotic translation, supported by Brazilian Sign Language (Libras) and the visual experience of deaf individuals, can aid the conceptual development of Botany. To this end, we have developed a teaching sequence guided by the action research cycle and supported by visual pedagogy and experimentation. This sequence comprises four pedagogical interventions (PIs), which were implemented at the Bilingual Centre for Deaf Students in Goiânia by a hearing teacher fluent in Libras during the first semester of 2023. The research participants were eighteen high school students from all three years of secondary education. Data was collected from video recordings of the PIs, translated into Portuguese, and subjected to conversation analysis. Our results indicated that intersemiotic translation aided the development of the concept of plants and that Peirce’s semiotics provides an understanding of the process of teaching and learning science to deaf individuals.

(2025-11) Barbosa, Hevellyn Gabrielly Dias; Matos, Gabriela Ferreira; Nascimento, Keythy Ravena Batista; Faustino, Gustavo Augusto Assis; Costa, Fernando Rocha da; Camargo, Marysson Jonas Rodrigues; Benite, Claudio Roberto Machado; Benite, Anna Maria Canavarro
This article investigates how to foster an intercultural and horizontal dialogue between chemical knowledge and the traditional knowledge of Afro-Brazilian terreiro communities, with emphasis on the use of sacred medicinal plants from the Cerrado in Goiás. The aim was to design and offer a workshop on producing herbal medicines with extended shelf life for traditional communities, supporting knowledge exchange and the appreciation of African ancestral knowledge. Using participatory research, we conducted interviews with leaders of terreiro communities between 2019 and 2020 to identify their interests in the use of medicinal plants for health maintenance. The final stage consisted of proposing a pedagogical intervention in the form of a workshop. The findings show that it was possible to establish a dialogue among ancestral, traditional and chemical knowledge, broadening the understanding of practices in a respectful, safe and horizontal manner through the preparation of two herbal products: aloe gel and bitter melon ointment.
A memória impressa nos balangandãs: olhares químicos negrorreferenciados nos moldes da lei 10.639/03
(2025-11) Santos, Vander Luiz Lopes dos; Camargo, Marysson Jonas Rodrigues; Benite, Anna Maria Canavarro
This experience report presents the articulation between traditional Afro-Brazilian knowledge and scientific concepts of Chemistry through an Afrocentric and Black-referenced pedagogical practice. The proposal was developed in a Pedagogical Intervention (PI) carried out with five female students from the third year of high school in Goiás, taking as reference the Afro-Brazilian jewelry of Colonial Bahia from the 18th and 19th centuries. The work was grounded in Law 10.639/03 and inspired by the theory of Afrocentricity, seeking to integrate cultural, symbolic, and scientific dimensions. For this purpose, we designed and implemented instructional material that engaged with chemical processes such as smelting, metallic alloys, redox reactions, and electrodeposition. Throughout the experience, the observation of classroom interactions, supported by conversation analysis, revealed how valuing Black epistemologies can enhance learning and foster critical reflections on science, identity, and ancestry. More than teaching Chemistry content, the activity contributed to strengthening antiracist education and to building a space of recognition and belonging for the students.

Unconventional Food Plants offer significant dietary and economic potential due to their rich nutritional and mineral content. Maranta arundinacea stands out for its food potential and use in the pharmaceutical field. This study aimed to analyse the nutritional, chemical and bioactive properties composition of the aerial and rhizomatic parts of M. arundinacea, highlighting their potential applications. The nutritional analysis revealed that protein and fibre content in the aerial parts (13.37 %) was significantly higher compared to the rhizomatic parts (5.12 %). Among the compounds identified through the Global Natural Product Social Molecular Networking (GNPS), rutin, quercetin, and kaempferol derivatives were the most prominent. These compounds are well known for their antioxidant properties, demonstrated against ABTS+, DPPH, and FRAP assays, which contribute to the overall health benefits of M. arundinacea. Collectively, these findings underscore the value of M. arundinacea as a valuable source of both nutritional and pharmacological benefits, supporting its long-term use as a valuable food, dietary supplement, and medicinal resource.

(2025) Faustino, Gustavo Augusto Assis; Alves, Camilla Ferreira; Nascimento, Keythy Ravena Batista; Santos, Itallo Junior Chaves dos; Vargas, Regina Nobre; Camargo, Marysson Jonas Rodrigues; Benite, Anna Maria Canavarro
In Brazil, the struggle of women for their rights, such as voting, freedom, autonomy, participation in the labor market, public life, and education, has been arduous and constant. Black women occupy a unique position in society, marked by multiple forms of oppression: gender, race, and class. Motivated by the desire to combat the disparity affecting women around the world, Black human rights activists have made significant advances in recent decades, ensuring greater attention to the issue of women's and gender rights abuses. With elements of participatory research, using Content Analysis (CA), our goal in this work was to investigate and describe the teacher training process in science, focusing on the development of a lesson conceived by course participants as part of the course evaluation around intersectionality and anti-racist education. Our results show that using Information and Communication Technologies (ICTs) with science teachers can be a way to diversify pedagogical strategies in educational practices. Additionally, the results highlighted the overlapping discriminations that shape Black women’s experiences, making it necessary to recognize the diversity and multiple dimensions of female identities. Finally, the analogies between intersectionality and their fields of study, resulting in words that express the complexity of the concept, encouraged students to reflect on the multiple dimensions present in the debate on this theme.
Miniaturized sample preparation strategies for the determination of N-nitrosamines in pharmaceutical products: A comprehensive review
(2025-12) Batista Junior, Almir Custodio; Rocha, Yuri Arrates; Chaves, Andréa Rodrigues
N-Nitrosamines (NAs) are classified as potent mutagenic impurities, raising substantial concerns due to their presence in various consumer products, including pharmaceuticals products. The detection of NAs in valsartan-containing medicines in 2018 led regulatory agencies to establish strict guidelines for permissible levels in drug formulations. The standard-gold analytical techniques for NAs determination have been chromatographic techniques (liquid and gas chromatography) coupled with mass spectrometry system, which present higher sensibility and accuracy for target NAs. However, accurate determination of NAs in medicines remains challenging due to their trace-level concentrations and susceptibility to matrix effects, carryover, and contamination of the analytical instrumentation, emphasizing the need for robust sample preparation strategies. Traditional sample preparation methods, although effective, often involve high consumption of solvents, samples, and extraction phases, along with substantial waste generation. In response, miniaturized sample preparation techniques have emerged as sustainable alternatives, offering reduced solvent usage, minimal sample requirements, and lower energy consumption, all while maintaining analytical performance. These green approaches not only align with sustainable analytical practices but also enhance efficiency and environmental compliance in pharmaceutical analysis. This review provides a comprehensive overview of recent advancements in miniaturized sample preparation strategies for the determination of NAs in pharmaceutical products, highlighting their analytical merits and potential for regulatory adoption.
Educação para as relações étnico-raciais (ERER) na formação docente em química: abordando a temática corante azul
(2025) Silva, Eliete Lucia; Camargo, Marysson Jonas Rodrigues; Benite, Anna Maria Canavarro
This study aimed to present and reflect upon an experience of incorporating the themes encompassed by Law 10.639/03—which mandates the teaching of African and Afro-Brazilian history and culture in basic education—into a teacher training program for Chemistry educators at a state university in the Central-West region of Brazil. More specifically, the focus was on the extraction of blue dye from Indigofera tinctoria, considered as a form of biotechnology originating from western Sudan (Mali). A pedagogical intervention (PI) was developed within a specific mandatory course in the program, targeting students in their seventh semester. The intervention was audio-recorded and subsequently transcribed for later analysis. The investigation was characterized as an action research project, and the data were examined through Conversation Analysis (CA). Our results revealed contradictions in the development of the PI related to discussions on racism; we identified epistemic shifts within the proposal, and we found it possible to discuss chemical concepts alongside topics related to African heritage and African history.
Metabolomic changes in rice (Oryza sativa L.) subjected to herbicide application through HPLC-HRMS and chemometrics approaches
(2025) Batista Júnior, Almir Custódio; Roque, Jussara Valente; Lima, Nerilson Marques; Soares, Daniel de Almeida; Silva, Mellissa Ananias Soler da; Chaves, Andréa Rodrigues
This study evaluated rice samples (Oryza sativa L.)─rice husk, husk and grain, polished grain, and unpolished grain─exposed to imazapyr, imazapic, and clomazone using high-performance liquid chromatography coupled to high-resolution mass spectrometry (HPLC-HRMS) and chemometric analysis. Partial least squares discriminant analysis (PLS-DA) was applied to HPLC-HRMS data, successfully distinguishing between herbicide-treated and control samples. Additionally, variable importance in projection (VIP) scores were then computed to identify key metabolites contributing to class differentiation, with higher scores indicating the most influential m/z values. These findings revealed metabolites affected by herbicide exposure and variations in the rice matrix. Furthermore, the most relevant m/z values were putatively annotated using spectral libraries, enabling the assessment of herbicide-induced metabolomic changes in rice. Herbicide treatment resulted in reduced free sugar levels across all rice matrices and led to a decrease in flavonoid content in the husk, indicating a potential suppressive effect on flavonoid accumulation. In addition, the herbicide treatment markedly disrupted the phenylpropanoid biosynthesis pathway. Overall, the combination of HPLC-HRMS analysis with multivariate approaches proved effective in detecting significant variations in the rice metabolome cultivated under herbicide application, paving the way for understanding the effects of herbicides in crop cultivation.
