description | Developing An Expository Model To Assess Animated Science Visual Representations Carlos E. GarcÌa School of Education and Institute of Cognitive Science University of Colorado, Boulder The study of visual information developed by students learning science, especially as it relates to animated models, is challenging because the researcher has to assess for representation of information (science content),the operations identified with the creation of an animated model(user interface), and variables that affect representational outcomes (real classroom concerns). The purpose of this presentation is to explore the usefulness of an expository model in the assessment of childrenís learning of science content through the use of animation software. The expository model is a criterion that includes the evaluation of spatial / temporal relations; the development of an operational unit; types of processing related to decomposition; types of processing related to the establishment of parameters; types of processing related to connections between nature and theory; and types of processing related to retrieval. These measures allow the classification of a particular representation as being tight, average or loose. The idea is to have a way of assessing animated science models while raising questions about possible reasons for particular visual outcomes. The presentation will explain in detail these categories given their role in the assessment of science content via a dynamic visual system. |
