These systems provide content, grading and assessment ofstudent work, and feedback to students while solving problems. Previous research has shownthat students’ value both online and handwritten homework. Even students who disliked onlinehomework found it to be at least somewhat helpful. The current project investigates ifperformance on higher stake (e.g., more heavily weighted in overall grade) activities is betterthan on lower stake activities in a Dynamics class and a General Physics I class.

in statics is a strong predictor of success in follow-onengineering courses and retention in the engineering majors. As a student’s introduction to therigors of engineering problem solving, statics creates a number of well-documented difficultiesfor many studentsv (Goldfinch, T., A. Carew, T. McCarthy, (2008)). A variety of strategies and interventions to improve retention of at-risk students andstudents in at-risk classes have been studied with active learning, project based learning, peerteaching and tutoring among them. Many of the techniques considered, however, have beendocumented in the literature as having mixed results. Most notable are conflicting studies thatindicate that traditional tutoring, problem solving sessions and

Likewise, instead ofpurchasing the computer board and software that accompanies the lumped mass apparatuses(which in this case was primarily developed for controls laboratory experiments), a world-classanalyzer (that includes computer software for control) was purchased so that the sensors andanalyzer can be used by students and faculty for research projects. This analyzer can also beused for acoustic measurements. A disadvantage is that the software that controls the analyzer isnot user friendly, and requires substantial setup time by the instructor. The laboratoryexperiments that were developed include the study of free vibration, forced vibration, 1 DOF,2DOF, and 3 DOF systems, dynamic absorber, modes of vibration, and the

No theoretical or numerical treatments associated with the finite element method arediscussed. Instead, some of the modeling concepts involving symmetry features and boundaryconditions are highlighted. As evidenced by the end of semester student evaluations, thestudents felt it was a good opportunity to get exposed to a general purpose finite element codesuch as ANSYS and its ability to solve problems involving stress concentrations associated withtension and bending situations.BIBLIOGRAPHYANSYS 12 (2009), ANSYS, Inc, www.ansys.comCrone, W.

engineering majors would take MEEN 221 as their main staticsengineering course. Starting in the Fall 2015 term, the Mechanical Engineering Departmentdeveloped a new Statics course exclusively for MEEN students, MEEN 225. This new course wasdesigned to better prepare students for subsequent MEEN curriculum. Topics covered are verysimilar, however MEEN 225 uses group projects in addition to homework and major exams forassessment. The students must also attend a 3-hour recitation every week in MEEN 225.Since the Fall 2015 semester when the divergence of the MEEN 221 and MEEN 225 coursesbegan, the department has seen a much higher percentages of students earn a grade of a D, an F,or Q-drop in MEEN 221 creating higher DFQ rates.
