Abstract Title: Student’s Pre-Conceived Views on Free-Body Diagrams
Abstract: Students enter their physics and physical science classes with a wealth of knowledge and pre-conceived beliefs.  There has been much work to understand these beliefs in terms of content, but not as much with the representations used to describe that content.  We investigate how students view Free-Body Diagrams before they receive instruction on how to construct and use them in a physical science course and then again after they had several weeks of instruction.  Our results show that students initially viewed the forces as being created by a person and that diagrams were typically an overhead view.  After instruction, forces were created both from objects and people and the diagrams were a side view of the scenario not an overhead.
