The anatomy of a typical module showsthe main features: Three recitations (Rec. n), one lecture (in the middle of the module), onerehearsal exam (RE), and one module assessment (MA). The recitations and rehearsal exams are75-minute sessions held in smaller rooms. The lecture and module assessment are 50-minutesessions held in a large lecture hall.Recitation. In the recitation periods, the students work through the “problem(s) of the day” ingroups, with the instructor and undergraduate teaching assistants (UGTAs) providing support,asking probing questions, giving advice, and generally activating the learning environment, asneeded.

Gulley found that a double pendulum was a useful case in learning the S-function of Matlab18. Swisher et al19 mentioned to use a double pendulum as a case study in anintegrated vibrations and system simulation course. Romano20 applied a double pendulum toresearching a modular modeling methodology in real-time multi-body vehicle dynamics. 2. Use of the case in ME 592-30/492-03 AMD In the fall of 2005, the double pendulum case was repeatedly used in teaching and learning AMD. The case and its variation were integrated with various teaching and learning scenarios. The first use of

Between the second and third attempt, however, theywere required to discuss their particular issues with the instructor before continuing the examcycle.
