A evasão em cursos de graduação em ciências exatas é um problema que todas as instituições de ensino superior estão sofrendo. Esse trabalho vem trazer o estudo e a aplicação de Metodologias de Aprendizagem Ativas na disciplina de Fundamentos de Eletrônica do curso de Ciência da Computação da UNEMAT de Alto Araguaia com o objetivo de reduzir a desistência e aumentar a permanência dos alunos nesta disciplina, na tentativa de se reduzir a evasão. São utilizadas duas metodologias ativas diferentes, a baseada em problemas e a baseada em projetos, e os resultados foram avaliados durante quatro semestres sequenciais

CNC machines are widely used in automated industries making the production process faster and more efficient. In addition, these machines have a high cost, making this technology inaccessible to a large part of the population. Thus, this work describes the process of building a multipurpose CNC machine with reduced cost through the reuse of recycled materials. Called REM-CNC Router, this CNC machine has the ability to operate in two different ways, allowing the engraving of images on the surface of materials by means of a laser, and the machining of printed circuit boards, 2D parts and even 3D, using a milling cutter. Produced from recycled materials, in addition to stimulating the reuse of e-waste, recycling of materials and encouraging the DIY culture, it has a reduced cost, making it a CNC machine with a great cost benefit and production quality.

According to the last Brazilian census, about 23% of the population has some type of disability, whether physical or mental. Given this fact, software systems and online educational content have to serve as tools to facilitate learning for students with disabilities, and must adapt to users so that there is a lower evasion of these students. This article presents a study of requirements elicitation to promote accessibility, using the Point of View-Oriented Survey technique, which recognizes the existence of several perspectives and offers a framework to discover conflicts in requirements from the perspective of different stakeholders. Thus, functional requirements of software for accessibility were listed, covering the categories of elements and characteristics of the pedagogical theory of connectivism.
