A funcionalidade da Avaliação em Matemática no Ensino Médio

The evaluation appears as a natural process in which a professional education to build a notion of content assimilated by the students as well as whether the teaching methods adopted by him are having an effect on learning of these. Long meant, to apply only to evaluate evidence, a grade and classify students in approved and disapproved. Even today there are teachers who believe that assessment is only in this process. However, this vision has been gradually modified. The evaluation is not at the time of carrying out tests and checks, but is an ongoing process, aimed at reflection for error correction and forwarding the student to acquire the expected objectives. This study was designed to analyze the data from the result of the survey, we can see that the form evaluative functions as an element of integration and motivation for the teaching-learning process. The speech of most education professionals interviewed here reflects the current notion that the evaluation process is currently understood not only as the result of the tests, but the results of the work and / or research that students perform. There are numerous evaluative techniques that allow the teacher to evaluate student performance and escape the traditional written exam, allowing teachers and students to dialogue sought to find and correct possible errors by redirecting the student for learning, motivating for the correction, and suggesting to him new ways of study for better understanding of the issues addressed within the class. The key is to understand that the evaluation process is not just about taking exams and assign grade. Evaluation is a continuous learning process that occurs every day in order to correct mistakes and build new knowledge.

Por dentro da sala de aula de professores de língua portuguesa: um estudo sobre a produção escrita

O presente trabalho discutiu as práticas de ensino da Língua Portuguesa nos Cursos Técnicos Integrados de Nível Médio em Agropecuária e Agroindústria do Instituto Federal de Sergipe – IFS / Campus São Cristóvão. Ao longo da investigação, realizada durante o ano de 2010, foram aplicados roteiros de entrevistas a alunos e professores da disciplina no instituto, com o propósito de mensurar e qualificar o índice de aproveitamento dos estudantes na aquisição da competência textual (produção escrita). Cabe destacar que esse procedimento foi antecedido de uma pesquisa exploratória, a qual norteou os rumos da investigação. Esta, por sua vez, teve por objetivo maior propor, mediante confronto com os resultados da prática de produção escrita dos alunos e dos documentos em arquivos, um quadro de estratégias para o desenvolvimento da referida competência. Na análise e discussão dos dados coletados, pôdese perceber que, no cotidiano das atividades de aprendizado da língua materna, muitos dos nossos alunos apresentaram-se interessados pelas práticas desenvolvidas, modo contínuo, de um lado; de outro, alguns manifestaram resistência às práticas de produção oral e escrita. Ademais, pôde-se igualmente perceber que os estudantes compreendem e “avaliam” as dificuldades por que passa o Instituto e sugerem a adoção de novas metodologias por parte dos professores. Como consequência do estudo, constatou-se que já existe um domínio de produção escrita por parte desses estudantes, todavia, a investigação detectou a necessidade do aprimoramento das técnicas e práticas em sala de aula, com o fim de melhorar o desempenho dos estudantes.

Relationship between antropometric, corporal composition and performance in young swimmers, boys and girls

The young athlete is physiologically unique from the adult and must be considered differently. The growth and development of their bones, muscles, nerves, and organs largely dictate their physiological and performance capacities (Bar–Or, 1983; Costill & Wilmore, 1994; Stager et al., 2008). Swimming performance, and the required times to reach a competition (TAC), shoud look for those diferences and should be compatibles with them.

A System Dynamics-Based Simulation Experiment for Testing Mental Model and Performance Effects of Using the Balanced Scorecard

This study develops a theoretical model that explains the effectiveness of the balanced scorecard approach by means of a system dynamics and feedback learning perspective. Presumably, the balanced scorecard leads to a better understanding of context, allowing managers to externalize and improve their mental models. We present a set of hypotheses about the influence of the balanced scorecard approach on mental models and performance. A test based on a simulation experiment that uses a system dynamics model is performed. The experiment included three types of parameters: financial indicators; balanced scorecard indicators; and balanced scorecard indicators with the aid of a strategy map review. Two out of the three hypotheses were confirmed. It was concluded that a strategy map review positively influences mental model similarity, and mental model similarity positively influences performance.

Modeling the Diffusion of Energy Performance Contracting

The Portuguese Energy Policy considers the development of a commercially viable and competitive market for energy performance contracting (EPC) as a main mechanism to achieve the objectives of energy efficiency improvement. This paper proposes a study to investigate how to achieve widespread adoption of energy performance contracting by means of system dynamics modelling and simulation. To explore and gather insights on this question, a system dynamics model representing the system of the Portuguese EPC market at industry level will be created. The simulation of that model will provide a helpful basis for analysing and explaining the development of key variables, and accelerating learning on the managerial, organizational and political adaptation processes that foster the diffusion of EPC adoption. The first phase of this research project aims at identifying and analysing the key factors and critical cause-effect relations that drive the adoption of EPC. With this purpose, a qualitative content analysis on relevant documents was performed and a set of interviews was conducted. That data was analysed to capture the critical variables and its interrelation to formulate a preliminary representation of the system structure as stock and flow diagrams.
