Constructing a Model of Digestion in a Primary School Using a Theatrical Performance

引用

Journal of Life Sciences 2012年第1期6卷 91-98页

作者： Maria J. Gil-Quilez Begona Martinez-Pena Milagros De la gandara Marta Ambite Marian Laborda Beagle （Research Group in Science Education） Dept. of Science Education University of Zaragoza Zaragoza 50009 Spain Primary School Fernandez Vizarra Monzalbarba 50120 Spain

The aim of this study is to analyze the difficulties of reading and writing experienced by primary school pupils when writing a script for a theatrical performance called ＂digestion＂. Our main research questions are： how does a theatrical performance help to reconsider the scripts and to build a model of the digestive system？ The pupils were encouraged to stage a theatrical performance for the whole school, explaining the digestion of a sandwich, a glass of water, an apple and a piece of chewing gum. The play helped to develop not only knowledge but also language. Having to produce a text for two different audiences, teachers and other learners led the students to debate between using ＂academic＂ vocabulary or more everyday vocabulary. Overall we found that they were more concerned with writing ＂academic＂ scripts, influenced by the texts that they consulted, than with writing a play accessible to all audiences.
