Tal consumo é um insumo fundamental na cadeia produtiva de alimentos, sendo um indicador importante para o monitoramento dos níveis de intoxicações e de resíduos que degradam o meio ambiente. Analisar o consumo de pesticidas em escala global ao longo do tempo é um grande desafio, pois os dados disponíveis são anuais e recentes. Este trabalho explora diferentes maneiras de otimizar a construção de modelos de previsão, utilizando diferentes abordagens por meio de combinações pareadas entre pré-processamento de dados e métodos de aprendizado de máquina. Foram avaliadas essas abordagens para obter previsões baseadas em dados reais sobre pesticidas nos dez principais países que os consomem. Os resultados mostraram que a utilização de modelos de aprendizado de máquina com desempenho satisfatório é difícil de se obter, considerando esse cenário de poucos dados e, ao mesmo tempo, peculiar de acord...

Através de aplicações, ao longo de dois anos e meio anos, em uma escola pública, mediante análises quantitativas e qualitativas, observou-se que o jogo denominado Cubo de Rubik, pertencente a cosmovisão dos discentes, pode não só melhorar os seus desempenhos, mas também auxiliar na prática dos conceitos ensinados. Esse recurso permitiu transferir o cotidiano da vida do estudante para o mundo da sala de aula, construindo uma ponte de aprendizado mais agradável e lúdica das disciplinas consideradas difíceis. Verificou-se também que, trazendo para a sala de aula essa visão comum (de um jogo), segundo uma metodologia livre, o aprendizado transformou-se em uma experiência nova e mais fáci...

Tidal, rocks, and glaciers movements, which take up to months to occur, can be seen in a few seconds with this technique. Swamps, deserts, and even submerged areas are places of difficult access and need to be observed. There is always a high cost involved in the process of capturing timelapse images. In this paper, a robotic tool is presented that meets the operational requirements to support these tasks. Among these new features is the ability to use idle time in the process of capturing images for this type of media. Its builtin camera is moved in different directions, being able to capture images for the generation of multiple time-lapse videos, using only one device. Because of this, this robotic tool is a facilitator to the construction of scientific, entertainment, and educational projects that make use of this type of unconventional data.

With this system, it is possible to provide greater security of access to a classroom, avoiding irregularities, such as falsified signatures on the presence sheet, or use of adulterated identities. It applies an image recognition process in which it seeks to extract relevant information from an image, then encode and compare it with other facial data stored in an image database. This information of the images represents a set of characteristics that present the variations between the images of the faces collected by the system and those contained in the image database. The Facial Recognition System is composed of two processing modules: training and recognition. It was applied in a high school classroom to evaluate the usefulness and accuracy of these algorithms for people recognition.

The relevance of the study is due to the fact of the conception of this tool arised from the extraclass view of a group of students who contributed to the development using robotics as a form of tool belonging to its universe outside the classroom. Three sessions were carried out on the use of the tool in the students' class in order to test their playful characteristics and to ascertain the ability to help learning of non-technical subjects of the students who were involved in the development of the same.

Although these changes have modified a small percentage of the vocabulary words, people are struggling to adapt to some of the new orthographic rules. Aiming to mitigate this problem using a ludic approach, we developed Orthographic Educational Game (JOE). JOE focuses predominantly on the rules of accents and hyphens. The game is divided into two modes: training and playing. In the playing mode, the current level of knowledge of the player in orthography is checked and measured. In the training mode, each word comes with a hint related to the rule that is being practiced at the moment. The game was evaluated through an experiment with both undergraduates and high school students. The results indicated that more than 80% of students enjoyed learning orthography through the game-based approach of JOE.

Sim-Evolution focuses on High School students, so its interface was designed to be joyful, helping to engage them. Although it was designed based on the concept of population genetics, knowing it is not a requirement for exploring TENS. Sim-Evolution models the population of a hypothetic bird species in two possible vegetations: forest or veld. Individuals of this bird species vary over two characteristics (color and beak type), with three possible phenotypes for each one. The user can choose individuals to form an initial population and monitor variation through successive generations. Birds breed independently of their phenotype, and natural selection (based on the fitness of each trait) was the only driven factor of population variation. Sim-Evolution was evaluated with High School students during a Biology class. Students were able to describe and analyze the simulation process from a scientific perspective, observing the phenomenon associated with TENS. They correctly associated the bird's evolution to different survivor rates associated with the different traits and identified evolution by natural selection as a population and not an individual/organism process. Our proposal opens the possibility that TENS simulator does not obligatorily require users to be familiar with population genetics concepts, which is especially interestingly for High School pedagogical uses.

Among these insects is the species Aedes aegypti, vector of several diseases like dengue and zika. It has a large incidence in tropical countries, having a significant number of cases in South America. Due to the annual epidemics of dengue, and aiming at promoting a more effective prevention measure, it was proposed the development of an unmanned aerial device, composed of a drone and a software with deep learning, capable of identifying foci and ejecting biomedicine capsules to eliminate the larvae of this insect, which proliferates mainly in foci of standing water. The deep learning software, using a backpropagation-type algorithm, is capable of identifying and classifying possible foci of Aedes aegypti, indicating to a controller the command to eject the biomedicine that eliminates the mosquito larvae, thus contributing to public health, by controlling the proliferation of such problem.

E necessario haver metodologias que ajudem os participantes das atividades de extensao a aproveitar melhor ferramenta ou recursos, para criar um ambiente no qual eles se tornem protagonistas e nao simples absorvedores da TI. Com base nessa necessidade, aplicou-se o Gestaltismo como um metodo para proporcionar com que varios recursos fossem criados, desenvolvidos e programados pelos participantes das atividades, baseado nas suas necessidades pessoais e em suas cosmovisoes. Com base em tres aplicacoes dessa metodologia, em tres turmas de extensao diferentes, foi possivel observar um incremento na motivacao de absorver novos saberes com uma ferramenta de TI que foi construida a partir da necessidade dos participantes, utilizando tecnicas do Gestaltismo, de modo que pode ser observado que esse metodo pode reduzir reatividades na introducao de Tecnologia da Informacao nas acoes de extensao.

Building different didactic techniques to help students learn and practice with Information Technology (IT) resources is common. However, applying these techniques does not necessarily mean that students may acquire knowledge. The differential idea of this work is to create an approach in which students are protagonists and not just absorbers of IT. Based on this perspective, we applied a Gestalt approach to assist students in practicing these technological resources. They produce new hardware and software tools during classes based on their personal needs and worldviews. We analyzed applications of this novel way of computer science teaching in three different schools. It was possible to observe greater motivation from the students to experience new knowledge from technological resources. The common aspect was that solutions were conceived and developed from students' needs. The development followed a Gestalt approach, which combines the idea of form and imagination. Thus, with this approach, reactivity towards IT was reduced. It helped construct technological tools to acquire propaedeutic knowledge.

Considering that vectors and vector quantities are a physics topic in which many students have difficulties, it is important to explore new ways to present them. In this vein, this study aims to explore a new m-learning application named Lab-Vetor. The application is designed for teaching and learning vectors on mobile devices. LabVetor can either be used by teachers in the classroom, through interactive whiteboards, and by the students at home as an m-learning training application. The LabVetor was evaluated by a group of students and showed to be a useful tool to assist the comprehension and reflection of the content learned in classroom. O conhecimento e compreensão de vetores e grandezas vetoriais é extremamente importante para descrever o movimento dos objetos na física do ensino médio. Considerando-se que vetores e grandezas vetoriais são tópicos da física em que muitos estudantes têm dificuldades, é interessante explorar novas formas de apresentá-los. Nesse sentido, este trabalho tem como objetivo explorar uma nova aplicac ¸ão de m-learning chamado LabVetor. O aplicativo é projetado para ensino e aprendizagem de algumas operac ¸ões simples com vetores em dispositivos móveis. LabVetor pode ser usado por professores em sala de aula, por meio de quadros interativos, e pelos alunos em casa, como uma aplicac ¸ão m-learning para treinamento. O LabVetor foi avaliado por um grupo de estudantes e mostrou ser uma ferramenta útil para auxiliar a compreensão e reflexão do conteúdo apresentado em sala de aula.
