Item Efeitos das tecnologias de realidade aumentada e virtual como recursos visuoespaciais na aprendizagem de geometria molecular(2024-10-14) Silva, Kleyfton Soares da; Correia, Paulo Rogério Miranda; http://lattes.cnpq.br/1028921713215334; Correia, Paulo Rogerio Miranda; http://lattes.cnpq.br/1028921713215334; Aguiar, Joana Guilares de; http://lattes.cnpq.br/7322160560603795; Cirino, Marcelo Maia; https://orcid.org/0000-0002-5377-382X; http://lattes.cnpq.br/7952492082756341; Gotuzo, Seabra, AlessandraThis research investigated the effects of didactic interventions mediated by augmented reality (AR) and virtual reality (VR) technologies on the learning of molecular geometry concepts. Given the complexity associated with learning molecular structure, this investigation identifies conceptual errors, visuospatial issues, and the use of digital technologies as important elements for developing effective didactic strategies. Utilizing a qualitative and quantitative, applied approach and an explanatory sequential mixed methods data collection and analysis strategy, the research was organized into three complementary studies. The first study aimed to identify conceptual errors related to molecular geometry through a diagnostic test applied to 55 undergraduate biotechnology students at the University of São Paulo. The results revealed difficulties in transitioning between two-dimensional and three-dimensional representations, emphasizing the need for didactic strategies with multiple representations. The second study, conducted with the same participants from study I, assessed the effect of AR on learning molecular geometry. Students were divided into two groups: one reviewed the subject with the support of a conceptual map with static molecules (group A) and the other with a customized conceptual map with AR (group B). The comparison of performance in the task of constructing physical molecules showed superior performance for group B, suggesting that emotional and attention factors may have contributed to a good spatial perception of the molecules. The third study, conducted at the University of Surrey, evaluated the effect of VR, complemented with other resources, on the understanding of molecular geometry. This study highlighted the set of tasks in the pedagogical intervention as engaging, facilitating learning regardless of students' prior knowledge level, and effective in leveling knowledge among different groups. The study conclusions emphasize the relevance of diagnostic tests to identify conceptual errors and the importance of integrating immersive technologies and practical activities in chemistry education. The findings reinforce the need for carefully planned, implemented, and evaluated didactic strategies to enhance performance in chemistry educational contexts.Item Impactos ambientais causados pelo descarte inadequado de pilhas e baterias(2022) Santos Júnior, Ronaldo dos; Oliveira, André Luiz dos Santos; Oliveira, André Luiz dos Santos; Barbosa, Amaury Franklin Benvindo; Silva, Kleyfton Soares da; Santos, Renan Atanazio dosFaced with the increasing advancement of technology, the production of cells and batteries has grown continuously. However, in their compositions they present highly toxic components called heavy metals, so when they are incorrectly discarded, they cause contamination in the environment and human health. Thus, this work aimed to show the impacts caused by the incorrect disposal of the same. The methodology involved research using articles, academic dissertations, journals and websites. A literature review was carried out between January and April 2022, in the following database: Google Scholar. With improper disposal, contact with moisture, water, heat and other chemicals is enough for toxic components to leak and mass contamination ensues. Taking as an example the environmental accident that happened in Bauru in 2002, where 314 children were contaminated by lead, causing blood lead and irreparable damage. In Brazil, there are currently some projects aimed at correct disposal, an example of which is recycling. In most treatment processes, a sorting takes place, with the aim of treating each type of electronic waste. This procedure (recycling) is promising and can be applied in serval places.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 Teoria e prática: uma proposta de Sequência Didática utilizando microscópio caseiro no ensino de ciências(2022) Santos, Rayane Lima dos; Oliveira, André Luiz dos Santos; Oliveira, André Luiz dos Santos; Silva, Kleyfton Soares da; Nascimento, Raul César da SilvaThe search for meaningful learning continues to be a challenge for many teachers, who need to plan their classes with the objective of achieving teaching that meets the needs of students. This work aimed to propose a didactic sequence for the teaching of "cytology" in the 1st year of high school, based on the Theory of Didactic Situations (TSD), having as a starting point the use of a homemade microscope. The methodology involved a qualitative and bibliographical research, seeking to suggest a teaching model based on TSD, which consists of the application of four phases: action, formulation, validation and institutionalization. The proposal is promising and can be applied in different curricular contents.
