So in a sense the question here is: Do students who exhibit specific difficulties in de-scribing rigid body motion at the beginning of Statics exhibit specific difficulties in assessingequilibrium at the beginning or end of Statics? If so, might identifying these students at the startof Statics allow the instructor(s) to more effectively address these students’ expected challengesand give those students a better chance of exiting Statics with a consistent and correct approachto assessing equilibrium? This work attempts to answer the first of these two questions.MethodologyTo test the notion that understanding a dynamic rigid body gives a better foundation for under-standing a static rigid body, students complete a pair of simple questions

However, the low overall utilization of the resource may be masking thepotentially significant difference between the two treatments seen in the high-access group.This investigation into homework solution format, as well as best-practices with regards toencouraging student use of the resource, will continue. Specifically, investigations are planned tostudy if providing students with a worked-out-homework solution (from a similar but notassigned problem) before the assignment is due is a more effective intervention than providingsolutions after the due date.Bibliographic Information[1] Steif, P.

: “Threshold concepts, once learned, are likely to bring together different aspects of the subject that previously did not appear, to the student, to be related3.” This is probably the most obvious connection this work due to the inherent need to apply fundamental principles of mathematics and science when solving complex engineering problems. For example, a statics problem may involve trigonometry, vector algebra, and Newton‟s second law of motion.  Transformative: Threshold concepts are “akin to a portal, opening up a new and previously inaccessible way of thinking about something . . . it represents a transformed way of understanding, or interpreting, or viewing . . . without which the learner cannot

ability that experienced engineers possess. “Most students do not find statics to be conceptually difficult, but are often overwhelmed by the myriad of small decisions that they must get correct if they are going to successfully solve a problem. Too often, this causes a student to question if he/she should continue to study engineering. The key idea implemented in ARCHIMEDES is a just-in-time feedback process for enhanced learning of problem- solving strategies.”7 The system divides the problems into steps that would logically be taken. For example, the first step in many statics problems is drawing a free-body diagram(s). Page

Many others are possible and the EGP can admit these and many other file types.Learning “content” is, however, not enough; we want students to understand the relationshipsamong seemingly disparate pieces of content.
