Exploring Middle School Science Students ' Modeling Process and Strategies When Using a Computational Modeling Tool

In this study, we explore and characterize middle school science students' modeling strategies when they are engaged in scientific modeling by the use of a computer-based modeling tool, Model-It. Three seventh grade science classes taught by three teachers at an independent school participated in the study. To capture students' actions, statements during the dynamic modeling process and cognitive strategies they used, classroom videos and video recordings while students used Model-It were collected during 1999-2000 school year. The findings show that Model-It allows students to engage in modeling activities (i.e., planning, building, and testing) and exercise a variety of modeling strategies. This computer-based modeling tool provides a unique opportunity for students to experience various situations that require them to analyze a system, identify causal and correlational relationships, synthesize parts into a coherent model, test and revise the model. This research provides us with a richer understanding of middle school science students' computer modeling processes.
