Assessing high school chemistry students' modeling sub-skills in a computerized molecular modeling learning environment

Yehudit Judy Dori, Zvia Kaberman
2011 Instructional Science  
Much knowledge in chemistry exists at a molecular level, inaccessible to direct perception.  ...  We present a hierarchy of modeling sub-skills, starting with understanding symbols and molecular structures, and ending with mastering the four chemistry understanding levels.  ...  Dori and Barak (2001) investigated the effect that teaching organic chemistry using virtual and physical models had on students' understanding of both new concepts and the spatial structure of new molecules  ...

Spatial modeling in cell biology at multiple levels

Arne T. Bittig, Adelinde M. Uhrmacher
2010 Proceedings of the 2010 Winter Simulation Conference  
With the supported level of abstraction, each of those offers a different perception of the spatial phenomena under study.  ...  These modeling languages allow an explicit description of spatial phenomena, and facilitate analysis of the temporal spatial dynamics of cells by a clear separation between model, semantics, and simulator  ...  CONCLUSION The insight that space plays a crucial role in understanding the dynamics of cell biological systems has fostered the development of diverse modeling approaches during the last years.  ...
