Abstract

EnglishAbstract: The aim of this study on conceptual learning in science teaching is to analyze scientific inquiry based on the subject Food Education and its transfers of meaning. Initially, survey activities were conducted in order to recognize prior knowledge of students and later, ninth grade students of Elementary School had contact with a didactic sequence of five investigative activities related to the subject. Inquiry was based on National Research Council references and conducted weekly. After that, four challenging activities containing problem situations were applied in order to investigate if transfers of meaning from inquiry to the new situations occured. Comparing the data obtained, it was possible to see that students had a satisfactory performance when they had to distinguish concepts related to food, nutrients, vitamins and minerals. These were better understood than some minerals and their functions in the body. portuguesResumo: O objetivo deste estudo acerca da aprendizagem conceitual no ensino de Ciencias foi analisar a transferencia de significados das atividades de investigacao envolvendo a Educacao Alimentar.

小学主题食品教育的研究活动与意义转移
本研究旨在从食品教育及其意义转移的角度,分析科学探究在科学教学中的作用。最初,进行调查活动是为了承认学生先前的知识,后来,小学九年级的学生接触了一系列与该主题有关的五项调查活动。调查基于国家研究委员会的参考资料,每周进行一次。之后,应用了四项包含问题情境的具有挑战性的活动,以调查是否发生了从探究到新情境的意义转移。通过比较所获得的数据,可以看出,当学生必须掌握与食物、营养素、维生素和矿物质相关的独特概念时,他们的表现令人满意。这些比一些矿物质及其在体内的功能更容易理解。摘要:本研究旨在分析科学教学中的概念学习在食品教育研究活动中的意义转移。最初,我们使用活动来调查学生以前的知识,后来采用了一个教学序列,其中包括五项与小学九年级学生饮食有关的调查活动。调查活动是根据国家研究委员会的方法制定的,每周制定一次。在此期间之后,我们应用了四项具有挑战性问题情境的活动来调查是否存在从调查活动到新情境的知识转移。将以往知识调查中获得的数据与迁移结果进行比较,可以注意到,除了了解某些矿物质对生物体的功能外,学生们在区分食物和营养素以及维生素和矿物质的概念方面表现令人满意。
