Paper ID #30062Replacing Graded Homework Assignments in StaticsProf. Charles S White, Norwich University Prof. White received BS, MS and PhD degrees in Mechanical Engineering from M.I.T. He has worked in government research (U.S. Army Materials Technology Lab), private industry (Gillette/P&G, The Velcro Companies, Saint-Gobain) and academia (Northeastern University, Norwich University). His return to academia in 2018 resulted from a desire to give back and share his experiences. Particular areas of exper- tise include constitutive modeling for mechanical behavior of materials, consumer product development, and

provided f1 is much greater than f2. CCW couple moment since the structure wants rotate CW. (correct answer choice) 2 students attempted It's stated that F1's magnitude is much greater than F2 so we can disregard to apply a heuristic the effect of F2 and focus on F1. A reaction at A would be equal and opposite (0 correct answers) of F1. It's my understanding that a single force cannot have a couple moment so it wouldn't have a couple but I'm still unsure on certain applications of couples.

students in the lowest quartile for standard deviation of the SDI,three reported high motivation regardless of the activity (see students 1661, 4786, and 7520 inTable 5).Student 7520’s average SDI by activity type did show, on average, higher motivation in moreactive learning settings. Comments revealed that passive classroom activities were not as“enjoyable” to this student, but their motivation was still high compared to other students due toconsistently low amotivation and relatively high identified regulation. Student 7520’s lowest SDIof 7.5 corresponded to the passive lecture L5STF, commenting that “A PowerPoint on a Fridayis kind of hard to pay attention to, especially when the lectures are typically more engaged.”Student 7520’s responses

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.

the DCIThe idea for a DCI began at a Mini-Conference on Undergraduate Education in Dynamics,Vibrations, and Strength of Materials that occurred in September 2002 [1]. The Force ConceptInventory (FCI) had been around since the early 1990’s and was recognized as beingsuccessful in spurring innovation in physics education [2]. At this meeting, participants agreedthat a Dynamics Concept Inventory could potentially provide the same benefits for dynamicsinstruction. A DCI team was formed and first met at the Concept Inventory Workshop at the2002 Frontiers in Education Conference in Boston (November 2002). The NSF-fundedFoundation Coalition was a key driver behind the development of the DCI and other conceptinventories.The DCI was developed using a

the movement of the pendulum change from the position before? Spend time changing the object and/or the location on the pendulum. Place multiple objects on the pendulum. Write down the team’s observations below.”After approximately ten minutes, students were then provided with guided exploration, askingthem to increase or decrease the weight of the object attached to the pendulum and compare totheir first scenario. For example: “Choose an object(s) with a lighter mass than 1. Attach to the bottom of the pendulum. Compared to 1, the mass moment of inertia: Increased Decreased Same”The total time for this activity was approximately 20 minutes.Upon completion of the pendulum activity, students were
storage in a freezer wasrecommended. An alternative is to use wet-resin layup, where the liquid resin and hardener aremixed just prior to use and added to the dry fibers with paint brushes and rollers. This process isquite messy and time-consuming. For several years, specimens for the class were made as largepanels from prepreg materials and then cut into individual specimens with an abrasive saw. Thismethod was also time-consuming and did not involve the students in the fabrication process.The development of “out of autoclave” prepreg materials as a cost-saving measure in aerospaceapplications has been ongoing since the mid-1990’s [5]. As a result of these efforts, reasonablypriced small quantities of high-quality prepregs that can be oven-cured
twosentences that the intention is to ‘understand how a steel, circular bar, loaded under torsion,behaves until failure.’For the second section of improvement, the preceding lab manual mostly contained experimentalprocedures in paragraph format, as shown in Figure 2, which made it difficult for students to followand understand. Thus, the authors decided to reformat the procedures in a numbering, hierarchicalscheme such that each step would be followed accordingly (Figure 3). This modificationeliminated the need of having to search in multiple paragraphs for necessary information anddeciding what to implement. In addition, the revised manual specified exactly the type of table(s)needed for recording experimental data. This allowed students to include

3’s was about the same. It is fascinating that in the span of 3 midterm exams, the performance of “corequisite” group improved by nearly 20 points, to the point that their overall mean score was statistically better than the “prerequisite” group (with up to 94% confidence), a complete reversal of the results of Exam 1. It is clear in this case that the “corequisite” group of students started to develop a better understanding of the course material between the first and second exams and continued to improve until the end of the quarter. On the cumulative Final Exam, which was identical in the two quarters, the two groups performed in a virtually identical manner. This suggests that by the
