RTEMS is an open source real-time operating system used in embedded devices across a wide range of processor architectures. Lego Mindstorms NXT is a programmable robotics kit from Lego, which may be used as an educational tool to build a model of an~embedded system with computer-controlled electromechanical parts. The goal of the thesis is to allow development of RTEMS-based applications for Lego Mindstorms NXT platform with the aim of employing the results of the thesis as a runtime platform used in the Embedded and Real-Time Systems Course. The thesis thus identifies a suitable way of porting RTEMS to Lego NXT, provides the corresponding runtime environment and discusses basic means for deployment and debugging of RTEMS application on Lego Mindstorms NXT.

The dynamic of Physics classes is restricted to presenting the subjects of the program content through problem solving and the use of mathematical language, without motivating/explaining why and/or how to use mathematics to solve the problem. Given these difficulties, the teacher should also look for ways to motivate students. That said, one of the alternatives is the employment by the teacher of diverse methods in the classes when feasible. With this in mind, this research’s main goal, a qualitative one, is implementing Educational Robotics in Physics Teaching, aiming at a meaningful learning for students of 1st stage of the Electrical, Mechanical and Chemical courses at SESI SENAI Unit in the city of Catalão. This research is based on the ideas of Ausubel (Meaningful Learning), Vergnaud (Field conceptual) and Vygotsky (social interaction). The analysis of a diagnostic exam applied to 98 students in these classes revealed that most part of them did not know about scientific knowledge of various Physics contents, such as average speed and Newton's Third Law. In this sense, it was developed and applied a didactic sequence of activities using Educational Robotics, which focus was mainly on those contents. It was noticed that during the performance of activities the use of Educational Robotics was well accepted by the students, since they participated actively and managed to understand the key physical concepts involved in the experiments. / O Ensino de Física, como se sabe, enfrenta diversas dificuldades, entre elas a falta de motivação dos alunos. A dinâmica das aulas de Física se restringe em apresentar os assuntos do conteúdo programático por meio de resoluções de problemas e do uso da linguagem matemática, sem motivar/explicar o porquê e/ou como utilizar a matemática para resolver o problema. Tendo em vista essas dificuldades, cabe também ao professor buscar meios de motivar os alunos. Sendo assim, uma das alternativas é o docente utilizar, sempre que possível, métodos diversificados em suas aulas. Pensando nisso, a presente pesquisa, do tipo qualitativa, tem como objetivo principal implementar a Robótica Educacional no Ensino de Física visando uma aprendizagem mais significativa dos alunos de 1ª etapa dos cursos de Eletrotécnica, Mecânica e Química da Unidade SESI SENAI de Catalão. Esta pesquisa fundamenta-se nas ideias de Ausubel (Aprendizagem Significativa), Vergnaud (Campo Conceitual) e Vygotsky (Interação Social). A partir da análise de uma avaliação diagnóstica aplicada aos 98 alunos, foi possível perceber que grande parte dos alunos não tinha a ideia do conhecimento científico de vários conteúdos da Física, como por exemplo, de velocidade média e da Terceira Lei de Newton. Nesse sentido, foi desenvolvida e aplicada uma sequência didática de atividades com a utilização da Robótica Educacional tendo como foco principal esses conteúdos. Percebeu-se que, durante a realização das atividades, o uso da Robótica Educacional teve uma boa aceitação pelos alunos, visto que participaram ativamente e conseguiram entender os principais conceitos físicos envolvidos nos experimentos.

TITLE: LEGO Mindstorms: Didactic utilization in mathematics with a focus on fractals ABSTRACT: The objective of this thesis is to determine whether the teaching of fractal geometry supported by computer and robotic LEGO Mindstorms NXT has its place in the education of primary and secondary schools pupils in the Czech Republic. The theoretical part focuses on key topics and personalities closely connected to fractal geometry problematics. It provides a brief historical overview of the fractal geometry development, its potential use in teaching mathematics (with reference to Turkish curriculum documents), and a description of LEGO Mindstorms NXT which can well serve as a manual for teachers and pupils. The practical part contains instructions for building a robotic turtle as well as a proposal of teaching block aimed to support pupils' algorithmic and geometric thinking including key competencies. Quantitative comparison of the results taken from Turkish studies and evaluation of the project by the author and pupils are a part of the experiment as well.
