Attention is seen as a selective, intensive and directed state of perception. Within the sports context, there is much of attention field to be explored. The goal of this work was to test the goalkeepers attention by means of two experimental tasks. Our hypothesis was that the sports practice, specifically in goalkeepers because of their training, enhances their performance in tasks apart from the peculiar concept of the sport. What is more: it provides a performance enhancement, if it is due to the perceptive component of discrimination, to the temporal placement of attention or to the attention s maintenance for extended periods; in other words, it provides a higher capacity of concentration and less fatigability. We compared 27 soccer goalkeepers, between the ages of 15 and 27, divided by their time of practice. In this study, we used a computer commercial program, configured to the creation of attention tests (Stim, Neurosoft. Inc.), which controls all of aspects of the task. We correlated the reaction time and the percentage of rights with the length of the goalkeeping raining in months (along with the age). We divided the group of goalkeepers into two subgroups by means of the training time median. Despite the high correlation between training time and age, in our sample there was no significant correlation between age and performance in both of the tasks. The correlation between performance and training time was highly significant on task I. we did not verify the correlation between performance and training time on tasks II, despite the significant correlation between the performance on the two tasks. Correlation analyses between training time and performance were carried out on the tasks, separated by blocks. On task I, the correlation between training time and performance in each block was always significant; both in the parametric and non-parametric test. On task II, however, there was no significant correlation between training time and performance in any of the blocks. In the categorical analysis, which is an analysis of the two groups that were divided into two subgroups by means of the training time median, the difference in performance between the subgroups was significant only on task I, in the total sum of rights (T-test of independent samples; F=4.36, p=0.037) and in the rights within the two blocks (block 3 p=0.048; block 4 p=0.026). With training time, the enhancement of what differs them and the increase in fatigability condition tend to refine and reduce. The sports practice can indeed enhance the perceptive capacity and the attention s maintenance, which is the basis of the human discipline for the achievement of any task. Consequently, an affective and somatic increase, besides a cognitive intellectual increase, brings a real applicability in people s quality of life / Alguma forma de atenção está continuamente presente na atividade consciente humana, trazendo implicações e interesses tanto de cunho clínico quanto para a Psicologia da Saúde. A atenção é entendida como um estado seletivo, intensivo e dirigido da percepção. Dentro do contexto esportivo a muito da atenção para ser explorada. O objetivo neste trabalho foi testar a atenção de goleiros de futebol de campo através de duas tarefas experimentais. Nossas hipóteses foram que prática esportiva, especificamente em goleiros, e em função do seu treinamento, melhora seu desempenho em tarefas dissociativas do contexto peculiar ao esporte. E ainda; havendo melhora no desempenho, se é devida a componente perceptivo de discriminação, ao alocamento temporal de atenção, ou à sustentação da mesma por períodos prolongados, isto é, uma maior capacidade de concentração ou menos fadigabilidade. Comparamos 27 goleiros de futebol de campo, com idades entre 15 e 27 anos; separados por tempo de treino. Utilizamos neste estudo um programa comercial de computador, configurado para a criação de testes de atenção (Stim, Neurosoft. Inc); que controla todos os aspectos da tarefa. Correlacionamos tempo de reação e porcentagem de acertos com duração do treinamento dos goleiros em meses (e com a idade). Dividimos o grupo de goleiros em dois subgrupos, pela mediana de tempo de treinamento. Apesar da alta correlação entre tempo de treinamento e idade, inevitavelmente em nossa amostra, não houve correlação significativa entre idade e desempenho em ambas as tarefas. A correlação entre desempenho e tempo de treinamento foi altamente significativa na tarefa I. Não verificamos a correlação entre desempenho e tempo de treinamento na tarefa II, apesar da correlação significativa entre desempenhos nas duas tarefas. Foram feitas análises de correlações entre tempo de treinamento e desempenho nas tarefas separadas por blocos. Na tarefa I, a correlação entre tempo de treino e desempenho em cada bloco foi sempre significativa; tanto em teste paramétrico quanto em teste não paramétrico. Já na tarefa II não houve correlação significativa em tempo de treinamento e desempenho em qualquer dos blocos. Na análise categórica, ou seja, dos grupos divididos em dois subgrupos pela mediana de tempo de treinamento; a diferença de desempenho entre os subgrupos foi significativa apenas na tarefa I, no total de acertos (T- test de amostras independentes; F=4.36, p=0.037) e em acertos nos últimos dois blocos (bloco 3 p=0.048; bloco 4 p=0.026). Com o tempo de treinamento, a melhora no que diferenciar e o aumento na condição da fadigabilidade, tende a refinar e a diminuir. A prática esportiva pode de fato melhorar a capacidade perceptiva e a sustentação da atenção, que é à base da disciplina humana para realização de qualquer tarefa. Conseqüentemente, uma melhora afetiva e somática, além disso, uma melhora cognitiva e intelectual traz consigo uma aplicabilidade real na qualidade de vida das pessoas

Badatelsky orientovaná výuka rostlinných barviv na 2. stupni ZŠ / Inquiry-based science education of plant pigments in upper primary school

Novotná, Apolena January 2017 (has links)
This thesis is focused on interconnection between education of plant pigments and inquiry- based science education in upper primary school. The theoretical section of this thesis deals with the current quality of education and knowledge level of Czech pupils in science subjects, as well as characteristic of inquiry based science education and description of various types of plant pigments. Evaluation of publications focused on occurrence of plant pigments in curricular document is another part of this thesis. The study revealed that plant pigments represent only a marginal topic of these publications. The next section of this thesis is a questionnaire survey about utilization of inquiry based science education among the teachers of biology in upper primary school. The results showed that most of the teachers were well acquainted with the method and applied it during their teaching. The last section of this thesis contains two proposals for experimental tasks of inquiry-based science education of plant pigments, which are focused on interface of biology and chemistry. Both tasks were successfully solved.
