CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Este trabalho aborda o uso de Objetos de Aprendizagem (OAs) voltado para o ensino de CombinatÃria e como esses objetos podem auxiliar no processo de aprendizagem dos alunos. Nesse sentido, o objetivo desse trabalho à verificar se a utilizaÃÃo de OAs nas aulas de MatemÃtica promovem uma melhor assimilaÃÃo dos conteÃdos relacionados à CombinatÃria, buscando despertar no aluno a curiosidade e a investigaÃÃo nesta Ãrea. Por isso, optou-se por um estudo experimental do qual participaram 20 alunos do 3o ano do Ensino MÃdio da Escola de Ensino Fundamental e MÃdio JoÃo Mattos, localizada em Fortaleza, CearÃ. Esses alunos foram escolhidos de forma aleatÃria e divididos entre dois grupos, experimental e controle, com 10 alunos em cada grupo. Para a coleta dos dados, foram utilizados, um questionÃrio socioeconÃmico e um teste de mÃltipla escolha sobre permutaÃÃo, arranjo e combinaÃÃo. Esses dados foram organizados e analisados com o auxÃlio do programa Microsoft Office Excel 2010. Os resultados mostram que o grupo que teve uma abordagem diferenciada (experimental) obteve um melhor desempenho em relaÃÃo ao grupo que teve uma abordagem tradicional (controle). / This work approaches the use of Learning Objects (LOs) facing the teaching of Combinatorics and how these objects can help in the learning process of students. Accordingly, the aim of this work is to check that the use of LOs in Math classes promotes a better assimilation of the contents related to Combinatorics, seeking to awaken in the student curiosity and research in this area. Therefore, we opted for an experimental study involving 20 students of the senior year of High School from School JoÃo Mattos, located in Fortaleza, CearÃ. These students were chosen at random and divided between two groups, experimental and control, with 10 students in each group. For the collect of data, were used, a socioeconomic questionnaire and a multiple choice test about permutation, arrangement and combination. These data were organized and analyzed with the help of Microsoft Office Excel 2010 program. The results show that the group that had a differentiated approach (experimental) obtained a better performance compared to the group that had a traditional approach (control). .

The aim of the study was to create and justify recommendations for differentiated development of speed abilities in young soccer players during in-depth specialization stage. We studied methods of estimation of speed abilities in soccer players, evaluated and analyzed speed abilities in young soccer players and elaborated recommendations on their differentiated development. Novelty of the idea is the separation of speed abilities into 9 manifestations for further development: speed of simple visual-motor reaction, speed of complex visual-motor reaction, speed of single movement, frequency of movement, speed of entire movement action, single explosive effort, start acceleration, distant speed (speed endurance), braking speed. Practical outcome is elaboration of set of exercise for differentiated development of speed abilities in young soccer players during in-depth specialization stage. Separate exercise complex was invented for each type of speed ability. These exercises may be used during the whole training process of soccer players. / Целью исследования является обоснование и разработка рекомендаций по дифференцированному развитию скоростных качеств у юных футболистов на этапе углубленной специализации. В результате исследования были изучены методики определения скоростных качеств у футболистов, проведена оценка скоростных качеств, анализ результатов и разработка рекомендаций по их дифференцированному развитию. Новизна исследования заключается в разделении скоростных качеств на девять проявлений для дифференцированного развития: скорость простой зрительно-моторной реакции, скорость сложной зрительно-моторной реакции, скорость одиночного движения, частота (темп) движений, скорость целостного двигательного действия, однократное проявление концентрированного взрывного усилия, стартовый разгон, дистанционная скорость (скоростная выносливость), скорость торможения (скорость остановки движения). Практическая значимость работы заключается в разработке комплекса упражнений с использованием различных средств и методов для дифференцированного развития скоростных качеств у футболистов на этапе углубленной специализации. Для каждого проявления скоростных качеств разработан свой комплекс упражнений. Данные упражнения можно использовать как в специальном микроцикле, направленном на развитие скоростных качеств, так и в повседневной тренировочной деятельности.
