Abordagens pedagógicas e sua relação com as teorias de aprendizagem / Pedagogical approaches and their relationship with the learning theories

A prática docente demanda o conhecimento de como o indivíduo aprende, como se origina e se desenvolve o aprendizado e como se transforma em experiência significativa de aprendizagem. O objetivo deste artigo é apresentar as concepções teóricas sobre o processo de aprendizagem dos indivíduos e sua relação com as abordagens pedagógicas adotadas nos modelos de cursos de graduação. Nesse sentido, os modelos pedagógicos foram agrupados de forma sintetizada, em modelos que se distinguem por estarem centrados no professor; no estudante; no saber; no meio de comunicação ou na técnica; no contexto social e na interação. Foram apresentadas algumas das principais vertentes discutidas na área da Psicologia do Desenvolvimento Humano, que influenciaram as tendências pedagógicas, como a Inatista, a Ambientalista/Behaviorista, e as Interacionistas. Discute a necessidade das práticas educativas serem conceitualmente fundamentadas.

Abstract: The teaching practice requires the knowledge of how individuals learn, how the learning originates and develops and becomes as meaningful learning experience. The objective of this paper is to present the theoretical conceptions of the learning process of individuals and their relationship to pedagogical approaches adopted in the models of undergraduate courses. In this sense, the pedagogical models were grouped in a synthesized form, in models that are distinguished by being centered on theteacher; on the student; in the know; on medium of communication or technique; the social context and interaction. Were presented some of the principal aspects discussed in the Psychology Human Development, influencing teaching trends, as Innate, the Environmentalist / Behaviorist, and Interactionist. Discusses the need of educational practices be substantiate conceptually.

Planejamento educacional / Educational planning

O objetivo deste artigo é discutir aspectos políticos e pedagógicos do planejamento educacional no contexto da universidade contemporânea. Nesse sentido, o texto aborda os princípios e a importância do planejamento educacional, o lugar e a definição de projeto político pedagógico, da organização curricular e do plano de aprendizagem como aspectos constituintes e integrados do planejamento. A compreensão das etapas apresentadas e da necessária integração entre todos os componentes do planejamento e desses no contexto social concreto é fundamental para todos os que desejam exercer a docência na área da saúde.

The purpose of this article is to discuss political and pedagogical aspects of educational planning in the context of the contemporary university. In this direction, the text addresses the principles and the importance of educational planning, the position and definition of political-pedagogic project, curricular organization and learning plan as integrated constituents features of educational planning. Understanding the steps presented and the necessary integration between all these components of the planning and the concrete social context is essential for all who wish to pursue teaching in health care field.

Hortaliças in natura ou minimamente processadas em unidades de alimentação e nutrição: quais aspectos devem ser considerados na sua aquisição? / Fresh or minimally processed vegetables in foodservices: what aspects should be considered when purchasing them?

Objetivo O objetivo do estudo foi avaliar as perdas ocorridas no processamento de hortaliças in natura, comparar o custo da aquisição de hortaliças in natura e das minimamente processadas e discutir as vantagens e desvantagens da utilização destas últimas. Métodos Foram calculados fatores de correção de sete hortaliças por meio da determinação do peso bruto e do peso líquido em triplicata e o peso aferido por balança digital. Foram calculados média, desvio-padrão e coeficiente de variação. Os custos do peso bruto, considerando a correção pelo seu rendimento líquido, foram comparados aos custos das hortaliças minimamente processadas fornecidos pelo fabricante em dois períodos. Resultados Os valores da abobrinha, cenoura, chuchu e mandioquinha minimamente processados foram, respectivamente, 8,6 por cento, 14,1 por cento, 4,6 por cento e 13,5 por cento menores em relação ao custo do alimento bruto no tempo 1, mas isso não se repetiu no tempo 2, quando os alimentos in natura apresentavam menor custo. Conclusão Conclui-se que inúmeros fatores inerentes ou externos aos alimentos influenciam diretamente na magnitude das perdas durante o processamento. Os métodos de trabalho e objetivos finais de cada unidade produtora é que devem definir qual produto é o mais vantajoso, considerando que os custos são variáveis, uma vez que a produção pode ser comprometida pela sazonalidade e pela oferta e procura dos alimentos, com repercussão na gestão de qualidade da unidade.

Objective The objective of the present study was to assess the losses that occur when fresh vegetables are processed, to compare the cost of purchasing fresh and minimally processed vegetables, and to discuss the advantages and disadvantages of using minimally processed food items. Methods Correction factors for seven food items were calculated by determining their gross and net weights in triplicate with a digital scale. Mean, standard deviation and variation coefficient were calculated. The costs of gross weight considering the correction for net yield were compared with the costs of minimally processed vegetables supplied by the manufacturer during two different periods. Results The costs of minimally processed zucchini, carrot, chayote and arracacha were 8.6 percent, 14.1 percent, 4.6 percent and 13.5 percent lower than their respective fresh counterparts at time 1, a fact that did not repeat itself at time 2, when these vegetables were less expensive when bought fresh. Conclusion In conclusion, numerous factors associated or not with the food directly influence the magnitude of the losses that occur during processing. The working methods and final objectives of each foodservice should define which product is more advantageous since costs vary and production can be affected by seasonality and the supply and demand of the food item, with repercussions on the quality management of the foodservice.

Validation of a food frequency questionnaire for assessing dietary nutrients in Brazilian children 5 to 10 years of age.

OBJECTIVE: This study aimed to assess the relative validity of a food frequency questionnaire (FFQ), previously validated to measure usual intakes in adults, for measuring dietary intakes in children 5 to 10 y of age. METHODS: Dietary intakes were measured using an FFQ and a 3-d dietary record. Healthy children, 5 to 10 y old (n = 151), were recruited from public schools and asked to answer the questions in the FFQ and to provide non-consecutive 3-d dietary records based on reported estimated portion sizes. Paired sample t tests and Pearson's correlation coefficients were conducted to determine whether the two instruments reported similar values for energy and nutrients. The agreement of quartile categorization between the two instruments was also examined. RESULTS: Estimated energy and nutrient intakes derived from the FFQ were significantly higher than those derived from 3-d dietary records. As expected, Pearson's correlations increased after adjusting for residual measurement error, presumably due to exclusion of the high within-person variability in intake of these nutrients. Moderate to high (r > 0.50) correlation coefficients were verified for some nutrients such as calcium, folate, vitamin B2, vitamin A, and vitamin C. CONCLUSION: This FFQ, originally developed for use in adults, appears to overestimate usual energy and nutrient intakes in children 5 to 10 y of age. Further work is necessary to conduct a calibration study to establish adequate portion sizes before instrument adoption in this population.
