Os jogos didáticos são ferramentas lúdicas utilizadas no Ensino de Química para suporte no trato dos conteúdos estudados em sala de aula. Viabilizando aproximar cada vez mais o conhecimento com a realidade vivenciada pelos educandos, o jogo pedagógico foi preparado para tornar a aprendizagem mais eficiente, participativa e estimulante. Diante disso, o presente relato de experiência objetiva expressar as etapas de construção e execução de um jogo, denominado “Quididático”, uma atividade lúdica desenvolvida por alunos atuantes no Programa Residência Pedagógica da Universidade Federal de Alagoas e inserida em uma gincana realizada no âmbito de uma instituição de ensino da rede pública de Arapiraca - AL, cujo público alvo foram alunos do 3º ano do Ensino Médio.  Este relato dialoga com os procedimentos para a organização da atividade, bem como discorre a respeito dos resultados, ganhos atingidos e experiências obtidas desde a fundamentação teórica até o seu desenvolvimento prático em equipe. Por fim, demonstra que habilidades podem ser adquiridas no processo e que os jogos podem contribuir muito para acepção de conteúdos durante o ensino de química.

In this work, we present partial results of a qualitative research that aims to investigate mathematical knowledge for the teaching and practice of mathematical modeling in Basic Education. For that, a data collection was carried out with a group of students of the Degree in Mathematics of the Federal University of Alagoas. The results showed that the researched group showed signs that subdomains of mathematical knowledge for teaching are emerging in initial training, but the perceptions about D'Ambrosio's conception of Modeling and the sociocritical perspective are still fluid, little structured, due to the little contact with the theoretical foundation and practice of Mathematical Modeling in the context of Mathematics Education, making it necessary that in the Mathematics Degree course, mathematical modeling becomes a frequent practice in a specific discipline or inserted in the different disciplines of the Mathematics area so future teachers will be prepared to apply it in their classes.

The construction of citizenship does not represent only a human aspiration, but a struggle for a dignified existence and for the opportunity to fight the deep inequalities that weaken society. Education has an important role in the formation of principles and values through the practices arising from school daily life, once the school adopts this perspective prioritizing democratic and participatory management, these aspects contemplated in the school project may represent an important tool for the construction of citizenship and youth protagonism in the school environment. Therefore, the present work aims to analyze the construction of citizenship having as a conception the implantation of democratic management and youth protagonism in the school environment. The research corpus was worked with studies on the construction of the democratic school, as theoretical reference we have Freire (1967; 1974); Gadotti (1992); Benevides (1994), from a methodological point of view, the study takes a qualitative, bibliographic and documentary approach. The results of the study indicate that the guidelines that guide schools and are responsible for providing an education based on the formation of citizenship face challenges and advances, and that the model must be constantly revised, in order to meet the objectives of an education for citizen formation.

Information and Communication Technology (ICT) in education brings great performances to students, since it allows advances in studies, as the educator makes use of numerous tools, including CTSA (Science, Technology, Society and Environment), which encompasses the current view of the world and its problems. The objective of this work was to analyze the perception of Biology teachers regarding the use of CTSA in the State Education Network of the Municipalities of Girau do Ponciano and Arapiraca, in addition to analyzing the pedagogical practice of these teachers regarding Ecology content. The research was carried out in six schools of the State Network of Alagoas and the data collection was done through the application of a questionnaire. It was observed that most of the teachers who participated in the research are women trained in Biological Sciences and X years of experience. The professors stated that they did not have difficulties in using the CTSA in the classroom, either through interdisciplinarity or through problematization. It is concluded that most of the teachers who participated in the research are women, and that they do not have difficulties in using the CTSA in the classroom.

Historically in Brazil, education aimed at young people and adults was characterized by the formation of subjects prepared for professional practice, considering the different stages of development Brazilian industry. Over the decades, this need continued to permeate the initiatives education and public policies, with few developments of a humanistic nature. However, with the changes generated by the economic scenario of the last 40 years, thinking about Youth Education andAdults only directed to the world of work means restricting the potential and the social protagonism of these subjects. Therefore, from the modern conceptions about Education of Young People and Adults, we seek in this article to reflect on the teaching of Physics in this modality of teaching, highlighting the role of this field of science in the scientific and emancipatory education of citizens, schooled, fit for professional practice, and capable of understanding the nature around them. The role of Physics in the professional and school formation of these professionals will be discussed in a critical-reflective way. subjects, highlighting the teacher's pedagogical performance in teaching the different contents that characterize the curriculum of this discipline in view of the current training parameters that guide this modality. This study has a qualitative bibliographic character, presenting research results carried out in the last decade, reverberating the important role of Science Teaching in schooling for the social exercise and for the world of work, contrasting with the old conceptions based on only in filling jobs.

The teaching of Science in High School prioritizes the substantive formation of subjects capable of understanding natural phenomena from laws, concepts and precise theoretical formulations. This appropriation of knowledge depends, in addition to the didactic aspects of teaching, on a modern curriculum, which prioritizes the technological advances produced by the different fields of science, contributing to the scientific training of students. Given this context, this article aims to discuss the importance and pedagogical possibilities of teaching the Physics of semiconductor materials in high school, considering the technological impact of these materials on modern society. To this end, a qualitative bibliographical study will be carried out, bringing together scientific works published in the last decade that emphasize the need for a curriculum focused on the Physics of the so-called 'active' components, represented mainly by the semiconductor diode and the transistor, completing the exposition of the study of electrodynamics. in high school. From the reflections of this work we prove the need to include the study of these materials to understand the main technologies present in the daily life of the digital society, making their users critical-reflective subjects of these resources, understanding their genesis, functionality, technical applicability, scope and evolution.

The present work, based on the Theory of the Imaginary, tries to find the imagery itinerary of José Luís Peixoto in the Return home, starting from the discussions about the myth of return - resonated since the Odyssey - and the Poetics of space, by Bachelard (2008), since these two images (return/home) are intertwined throughout the poetic narrative, which Added to these two founding elements of the text, it is observed how time in the closed space of the house unlocked, in the subject, feelings of fear and uncertainty in the face of the present. In this sense, it was found that the image of the house, in the aforementioned book, still recovers the symbolic of a protective space, updated in the experience of social isolation. The same update movement happens in the recovery of the Homeric myth, from which one can think of how the subjects found the need to return to the family environment because of the pandemic, at the same time that the For the realization of this article, we resort to the theoretical-methodological postulates of Bachelard (2008), Durand (1993), Mello (2002) and other authors.

The present work had the objective of carrying out a survey of the floristic composition and tree diversity on a rural property located in the municipality of Porto Nacional, state of Tocantins, through a forest inventory with simple random sampling. Five 20x50 meter plots were allocated and the height and HCV (>10cm) of the plants were measured. For each sampled species phytosociological parameters regarding frequency, density and dominance were calculated, in addition to the importance value index (IVI), using the FITOPAC program. The similarity between the plots was investigated using the cluster grouping analysis of the R statistical program. The survey resulted in 1,061 individuals, belonging to 35 families and 81 species, among which the most important was Qualea grandiflora, known as pau-terra-da-folha-larga. The Fabaceae family was the most representative with 21 species. The cluster analysis inferred that there is a division into three large groups. One group shows the proximity between areas 1 and 2, the other the similarity between areas 4 and 5, and the last group contains only plot 3, and indicates a greater similarity with plots 4 and 5. The results obtained show the great wealth and diversity of the Cerrado vegetation, demonstrating the real need for more phytosociological studies, so that, based on these, actions can be taken to develop conservationist policies that prioritize the rational use of resources, ensuring the maintenance of this great diversity of plants and environments.

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is an important pest of Brazilian agriculture, whose management is oriented mainly towards controlling larvae. The objective of the research was to analyze the effect of chemical insecticides on fourth instar larvae of H. armigera. The research was conducted under laboratory conditions, corresponding to the treatments control, zeta-cypermethrin (37.5 mL /500 L); lambda-cyhalothrin (75 mL/ 150 L); chlorpyrifos (1.0 L / 300 L); bifenthrin + carbosulfan (1.0 L / 350 L); and beta-cyfluthrin (60 mL / 250 L). The bioassays were conducted in plastic containers containing an artificial diet. After treatment applications on the food substrate, and subsequent drying, two larvae were inserted per container, the set of four containers being considered a replicate, totaling four replicates per treatment, with mortality evaluations after 24, 48, 96 and 144 h after the applications. The sublethal effect was analyzed by evaluating the average weight of larvae and pupae (g), and emergence of adults (%). The active ingredients chlorpyrifos and bifenthrin + carbosulfan caused 100% mortality of fourth instar larvae of H. armigera from 48 h after the applications. After 96 h of phytosanitary application, lambda-cyhalothrin was responsible for causing mortality above 80%. Regarding the sublethal effect, better results were observed in the lambda-cyhalothrin and beta-cyfluthrin treatments, influencing the average weight of the larvae and the emergence of adults. The active ingredients chlorpyrifos, bifenthrin + carbosulfan and lambda-cyhalothrin are potential insecticides in the management of fourth instar larvae of H. armigera.

In the last ten years, the development of sensors with greater accuracy and precision due to improvements in manufacturing processes has enabled the expansion of their use in several areas. However, the purchase price, mainly of products from renowned manufacturers, in view of their applications, can make simpler projects unfeasible. The sensor data fusion technique is a viable alternative to resolve this issue, as mathematical models can be proposed and used in different situations. These models allow improving the data obtained in order to generate reliable information. Therefore, the objective of this work was to verify the performance of multiple linear regression applied to the fusion of redundant quantitative data from 5mm LDR sensors in estimating the luminous intensity (LUX) in simulated scenarios. To carry out the experiment, 3 LDR (Light Dependent Resistor) sensors, 3 LM393 signal conditioners, 1 USB 6009 DAQ data acquisition board (14 bits), 1 LT40 Extech luxmeter, in addition to the LabView software were used. It was found that LDR A and B sensors showed higher levels of accuracy. Furthermore, a significant improvement in the level of accuracy was found when combining data from sensors A and B in the form of multiple linear regression.
