for Engineering Education, 2013 Discovery Learning Experiments in a New Machine Design LaboratoryAbstract A new Machine Design Laboratory at Marquette University has been created to foster stu-dent exploration with hardware and real-world systems. The Laboratory incorporates areas forteaching and training, and has been designed to promote “hands-on” and “minds-on” learning. Itreflects the spirit of transformational learning that is a theme in the College of Engineering. The goal was to create discovery learning oriented experiments for a required junior-level“Design of Machine Elements” course in mechanical engineering that would give students prac-tical experiences and expose them to

The module can also be used to illustrate the effects of the liftforce on larger particles. Student can select values of the particle diameter and density,the number of particles, and the centerline fluid velocity and understand the relativemagnitudes of the different forces. Figure 1.

Clearly, a more contrasting backgroundand better lighting would improve the quality.This case illustrates the approach of combining recordings from the camera with video fromother sources. A final video was produced using the screencasting software, Camtasia Studio7,in which computer desktop work was recorded and combined with video recordings of thespring-mass system motion from the camera.At left in Figure 8 is a depiction of the type of textbook system often considered in mechanicalengineering course work that can be used to represent the actual simple physical system inFigure 7.

, and ARM the decision was made to use theSTM32VLDISCOVERY board utilizing a Cortex-M3 microcontroller from STMicroelectronics3 along with the Keil4 development environment from ARM. To facilitate easyconnections to existing laboratory equipment, a custom enclosure and interface circuitry weredeveloped. This provides easy access to digital and analog I/O and a serial interface tocommunicate with a terminal program running on a PC.These tools were chosen for several reasons. Keil makes a free version of its development toolsavailable for download, with the only major limitation being the size of the code able to becompiled. By choosing a free set of development tools, students were able to install the tools ontheir personal computers to work on

andperformed several experiments with the aim of using them in mechanical engineering courses.During these activities, the URF was supervised by the second author. The aim was to use theseexperiments as parts of a laboratory program for courses like Strength of Materials and Design ofMachine Elements. In this way, students would gain necessary hands-on and real-worldexperience about concepts that would otherwise be abstract and intangible. These activities arecontinuations to those performed in the past1.The value of hands-on experiments and how they strengthen learning has been discussed in manyresearches.

0.002% uncertainty. To somestudents, this appears to be a reasonable if not a preferred representation of the final answer. Inan engineering thermodynamics course, this concept is more difficult for students since propertyvalues reported in tables often are specified at 6 significant digits, which can be interpreted as1/500000 or 0.0002% uncertainty. Having property values in thermodynamic tables expressed to6 significant digits, contributes to the students’ perception that more digits are better.Students are expected to learn to estimate uncertainties in laboratory measurements and be ableto propagate these to final reported measurement values. This is expected in ABET1 outcome (b)describing the “ability to design and conduct experiments

reading, assigned homework problems, interactive exercises, andpower-point presentations. Students are responsible for learning basic course material outside ofclass time. Unlike an online class, an IC includes face-to-face time with the instructor inclassroom or laboratory setting where the material learned outside of class is discussed andapplied. The IC allows an educator to present course material in several different formats, and soengages the different learning styles and preferences of students. The IC format encouragesstudents to become self-learners and help prepare them for how they will need to learn aspracticing engineers. Our experience shows that the IC format can free class time for learner-centered activities without sacrificing

Systems and Control” courseThis is a senior level course for Mechanical Engineering which introduces students to modelingand design of closed-loop control systems. The textbook used is “Modern Control Systems”, 12thedition, by Dorf and Bishop. Many Mechanical Engineering students find fundamental conceptssuch as closed-loop control systems and transfer functions as very abstract and difficult to grasp.The extensive mathematical derivations required are somewhat alleviated by the use of Matlaband Simulink throughout the course. As the course does not have a laboratory component there isa gap between theoretical concepts and practical applications in the class. The LEGO basedmodules were developed to bridge this gap at least partially. The first
