Item Um estudo comparativo entre metodologias ativas para desenvolvimento de habilidades de pensamento computacional no ensino de robótica(2022-02-16) Lima, Huan Christopher José de; Rodrigues, Rodrigo Lins; http://lattes.cnpq.br/5512849006877767; http://lattes.cnpq.br/2033883465489052With the inclusion of teaching of computing in basic education, through a Resolution that instituted and guided the implementation of the Common National Curricular Base (know as BNCC in Brazil) application of computational thinking and robotics for basic education will be more and more presents as compatible didactic resources with increasing skills and society's abilities to awaken the student as an agent capable of analyzing and investigating the adversities of the present day, which is immersed in technological solutions.In this sense, we seek in this study to analyze the progress of two classroom groups during the learning of computational thinking, using a robotics kit as an educational tool, taught through two active teaching methodologies: gamification, in the morning class, and learning based in problematics, in the afternoon class. In order to understand the students' evolution level and thus be able to compare the two methodologies, a pre-test was applied in the first class and a post-test in the last class in both classrooms. Both the pre-test and the post-test contain the same twenty questions and to solve them, the students used the concepts of the four pillars of computational thinking. From the data collected, we can understand that the level of students' knowledge absorption in activities that require decomposition, pattern recognition, abstraction and algorithms can vary from pillar to pillar, not only according to the active methodology used in the course, as also with adverse factors such as the age of the students, since students under twelve have abstract thinking still in the development.Item Kit educacional como facilitador do processo de ensino aprendizagem na construção do conceito de biomas brasileiros(2023-04-19) Silva, Ana Carolina Soares; Couto, Janaína de Albuquerque; http://lattes.cnpq.br/7709040837130788; http://lattes.cnpq.br/4797438152053136The active methodology is a tool that seeks the best ways to put knowledge production into practice, it is considered something completely different from what we find today in educational institutions. Therefore, the curriculum must be organized to allow the school to successfully play its role in training students and to achieve its objective. The use of these methodologies can favor the student's autonomy, arousing curiosity, stimulating individual and collective decision-making, arising from the essential activities of egalitarian practice. The objective of this work is to analyze the contributions of an educational kit for the construction of concepts about Biomes, in the perspective of an active approach. The methodological proposal is a qualitative research of an interpretative nature, with students of the third year of high school in a State Technical School in Gravatá. The intervention was based on the Kelly Experience Cycle - CEK, which breaks down the intervention into 5 stages: anticipation, investment, meeting, validation and constructive review. Furthermore, before the CEK, the Verification Questionnaire Before the Action (QVA) was applied and when the CEK was concluded, the Verification Questionnaire After the Action (QVP) was applied, these questionnaires being the documents analyzed in this research. From the results, we observed advances in relation to the construction of concepts, not only about biomes, but also concepts about greenhouses and endemic species. Therefore, the use of educational kits aimed at the study of biomes contributed significantly to the students' teaching and learning process.Item Movimentação de um robô uniciclo utilizando controladores PID discretos(2021-07-20) Mei, Filipe Peticor; Medeiros, Victor Wanderley Costa de; Gonçalves, Glauco Estácio; http://lattes.cnpq.br/6157118581200722; http://lattes.cnpq.br/7159595141911505; http://lattes.cnpq.br/2113269128469015Autonomus robots are those who are able to complet tasks and goals in unstructured enviroments. One of the main goals of these type of equipment is to complet tasks that are considered to be repetitive, dangerous or impracticable to humans, beign used in domestic or industrial environments. To reach that goal, it’s essencial that the autonomous robot has a good location system. Various types of trajectory system control algorithms are proposed and the PID control is one of the classical controls that are popular in many aplications, making it possible to use it as a navigating system. Therefore, this reasearch proposes the development of a robot prototype, to asses how a digital control PID assists the development of it’s movement.Item O uso de metodologias ativas de ensino associada à robótica educacional com alunos do Ensino Fundamental: relato de uma experiência(2020-11-04) Cupertino, Gabriela Barbosa; Barros, Abner Corrêa; http://lattes.cnpq.br/3825998752196688; http://lattes.cnpq.br/6157059647848581The active teaching methodologies are teaching-learning approaches that are characterized by leading the student to assume a greater role in the dynamics of knowledge acquisition, so that the teacher starts to act no longer as a greater holder of information and knowledge but as a facilitator and mediator of this process. In this approach, the student is encouraged to participate actively in the construction of knowledge through the search for solutions to relevant problems in his life context and through constant exercise of critical sense. The objective of this monograph is to bring a critical account of the use of active teaching methodologies (Problem Based Learning, Peer Learning and Maker Movement) associated with technological tools (Educational Robotics and Design Thinking) in an elementary school in the rural area of the Vitória de Santo Antão - PE. Both the pedagogical methods used and the impact of using these methodologies on the performance and school experience of the students involved will be analyzed. The results observed in this throughout process allowed us to conclude that the adopted methodologies provided students with gains in areas that went beyond the simple acquisition of academic knowledge, with significant improvements in the capacity for socialization, teamwork and in the construction of critical and questioning thinking.Item Verificação eficiente de robôs educacionais(2021-03-03) Correia, Lucas Francisco Pereira de Gois; Nogueira, Sidney de Carvalho; http://lattes.cnpq.br/9171224058305522; http://lattes.cnpq.br/1957154709677653Educational robotics is an area of growing interest within educational institutions. Due to it's low cost, program environments for virtual robots have been developed to support the teaching of computing, programming and robotics concepts. The main debug tool available in such environments is the simulation of the robot within a virtual map. Debugging is performed by observing the robot moving across the map: it is not possible to analyze automatically if a program will manage to conclude a specific objective. Approaches to automatically analyze virtual robots are an important teaching tool for an eficient and accurate evaluation of robots. The objective of this project is to improve an automatic verification approach of robot programs. This approach translates programs in the ROBO language to the formal notation CSP and uses the FDR model checker to automatically analyze the program's behavior. The result returned by the model checker is used to inform if the analyzed program has the expected behavior. The main improvement proposed by this project is the implementation of a ROBO to CSP translator that generates a more eficient CSP model to be analyzed, if compared to the model produced by the previous translator. We could observe, through empirical evaluation, a significant reduction in the time to analyze the CSP models obtained from the new translator. The proposed translator presents an almost constant analysis time for the maps considered in the empirical evaluation, while analysis time of the models produced by the previous translator shows an exponential growth in relation to the map's size where the program is analyzed. Another contribution of this work is that the new translator accepts ROBO programs with any command of the language, while the previous translator could only deal with a subset.Item Um algoritmo para geração de Navigation Meshes em mapas bidimensionais homogêneos: uma aplicação no jogo Dragon Age: Origins(2019) Costa, Ingrid Danielle Vilela; Bocanegra, Silvana; http://lattes.cnpq.br/4596111202208863; http://lattes.cnpq.br/6113606913639280In the field of electronic gaming and more recently in robotics, autonomous agent soften need to repeatedly solve the problem of searching for the smallest path. This need can eventually consume a lot of resources and demands optimizations to make these searches more efficient. Such optimizations may include improvements in search algorithms, map representation, data structures used. This work presents an optimization for search algorithms based on the reduction of the search space by means of an automatic Navigation Meshes generation algorithm which are networks of walka blemap areas implying in a reduction of the search space and consequently improving the search processing time. The generation of Navigation Meshes is a problem with no consolidated solution. To prove the heuristic, path finding problems were solved on 156 benchmark maps. The path findings were performmed by the A* algorithm and the solutions were compared between the original maps and the optimized ones. An average search space reduction of 97.42% was achieved, with a standard deviation of 0.026and the search had an average marginal reduction in execution time of 46.76%.Item Uma abordagem da robótica sustentável para o ensino de química(2018-08-29) Albuquerque, Edson Severiano de; Leão, Marcelo Brito Carneiro; Souza, Rodrigo Baldow de; http://lattes.cnpq.br/7464451242948613; http://lattes.cnpq.br/2437159839645198; http://lattes.cnpq.br/7276831284746984This essay analized a pedagogical pratice with a sustainable robotics in chemis-try teaching, observing how this work could contribute with teaching and learning of topics discussed in the following activity. Some meetings up were realized with 9th grade elementary school student from a private school in order to discuss some chemistry topics related to enviromment education. An eletronical waste collection was done in the neighborhood and these things were used by the students in the de-velopment of three prototypes. After these artifacts building, a questionnaire was aplied to the students and their results were categorized and organized in charts, and later analized. This activity made the students undestand better the problems of dis-posal eletronical waste, promoting, in addition, some solutions, and could enable a praticing where the students learned the real chemistry that many times has been studying only in theory.
