Necessidades formativas em Matemática representadas nas vozes de um grupo de professoras dos anos iniciais da rede pública de ensino

Teacher training processes, initial and continuing, and professional practice of teachers who teach Mathematics in the early years are highlighted in the literature as complex, but also are regarded as the way to overcome many difficulties in teaching this component curriculum in the school stage in question. The aim of the study was to investigate how the training needs in Mathematics are represented by a group of teachers in the early years of elementary school of public health system of the city of Uberlândia, State of Minas Gerais. The research, qualitative approach, had as object of study the training needs, in Mathematics, of teachers in the early years. The research involved 16 teachers from two schools in the municipal public schools of that city. Data were collected through questionnaires, non-participant observations, semi-structured interviews followed by group and individual. Analyses were performed by means of thematic categories, founded by content analysis. Data interpretation allowed to understand training needs in mathematics that are presented to the collaborating group from their professional practice, considering the knowledge and skills necessary to teaching. It is understood that the teachers of the study group have major limitations in relation to the specific content and didactic knowledge of Mathematics content, however, the concern is that demonstrated not always being aware of it. Moreover, the difficulties experienced in teaching practice proven to be overcome by sources and non-formal training activities, primarily through more experienced colleagues in the profession. Thus, it becomes difficult to think the initial and continuing training courses for teachers without the training needs of the teaching practice is appreciated as an object of study.

Influência das alturas iniciais de pasto diferido na recria de cordeiros sobre o desempenho na terminação em confinamento

The objective of this study was to evaluate the productive performance, metabolic and feeding behavior of sheep after ninety days deferred pasture at different heights. The experiment was conducted at Capim Branco experimental farm of the Universidade Federal de Uberlândia. During the period of 90 days, from June to September 2013, forty-eight crossbred lambs Santa Inês x Dorper, divided into groups of four animals, occupied twelve pickets deferred pasture with four initial heights (15 cm, 25 cm, 35 cm and 45 cm). During this period we evaluated the structural characteristics of pasture. For confinement, from September to December 2013, 32 of these animals were used (16 males and 16 females), divided into four bays, separated as pasture were using. The consumption was assessed daily, while biometric measurements were made every 21 days. In relation to gender, there were differences in average daily gain weight. Reviews of feeding behavior occurred at the beginning, middle and end of the experiment for 24 hours. The rumination and leisure activities do not present statistical differences, both initial height of pasture and by period. The time spent on intake was higher during the daytime both treatments starting height as the experimental periods, however, rumination activity was more intense at night. Blood glucose was achieved in five periods of the day, while other metabolites have been obtained with a collection made fortnightly. The different initial heights not promoted effects on blood glucose. The harvesting times were not affected. However, there was a reduction of basal blood glucose of animals throughout the experimental period. There was a significant interaction between the initial pasture heights and periods of evaluation of basal glucose. Cholesterol and triglyceride levels were below recommended levels, however the final phase of confinement cholesterol level increased significantly. The values of VLDL and GGT were above the reference range. FA and AST showed average values within the recommended values. Total protein was influenced by different initial heights of pasture. The creatinine and albumin had values below the recommended range. Moreover, the albumin decreased during the confinement time. Uric acid showed close to the recommended maximum. There was stabilization of compensatory growth, with modification of consumption and weight gain at 45 days of experiment.

Concepções dos professores da educação básica sobre as feiras de ciência

Currently the Science fairs in Brazil have gained great incentive, examples are the regulations that the government has been implementing in education and the financing of public calls for events throughout the national territory. However, even with this incentive, some researchers point out that the scientific fairs and shows are still interpreted as an extemporaneous work by teachers. In order to know the views of basic education teachers about the fairs of Science, proposed to carry out this research. Given this situation, based mediation theory and sociocultural interaction Vygotsky (2001), the theory of instrumentalism Dewey (2002) and the proposed education through research Galiazzi e Moraes (2002), we sought to understand the importance of fair and their benefits as well as the presence in the talks of respondents. In order to analyze the answers of respondents, used to discourse analysis proposed by Eni Orlandi (2009), in which it is observed and is an interpretation of the speech of teachers, considering their interpretation and how to shape their thinking on the research object. In analyzing the results of the survey, it was noted that the teachers interviewed know the importance and objectives of science fairs, however experience difficulties that often does not allow these events to be carried out. In seeking to assist them to minimize these difficulties, it was realized the need for a product to make available guidance on how to develop research projects and assemblies of science fairs, that would provide an education for the research. Thus, resulting from research, was set up a blog and a booklet with texts, articles and report templates.
