Her grandmother stopped to wave at her in the same moment that Mabel wentracing down the hill to embrace her (for she hasn’t seen her grandmother in a great while). Ourchallenge to the students: How can we make sure that Mabel will meet her grandmother with agentle kiss, rather than racing by her, stopping short, or crashing into her?Transferable Educational Elements: The Engineering Design Process (EDP) is introduced as a Page 22.592.12framework for meeting a human

We will assign values 1, 2, 3, 4 and 5, which means A=1,B=2, C=3, D=4 and E=5. Because questions 2, 4, 5, 6, 9 and 12 are negative questions, theratings A, B, C, D and E, of these questions are assigned 5, 4, 3, 2, and 1. The responsesfrom the 33 post-surveys are included here (Table 1). Table 1: Descriptive Statistics N Mean Std. Deviation Variance VAR00001 41 2.8049 1.0055

multi-faceted, multidisciplinaryengineering issues. They are then asked to determine the most important problem/s and todiscuss stakeholders, impacts, unknowns, and possible solutions. Table 2 presents a summary ofsample scenarios, and Appendix B provides three full scenarios with instructional prompts. TheEPS Rubric, an analytic rubric, was developed to measure the extent to which studentperformance in response to a given scenario achieved the six learning outcomes associated with Page 22.38.2the ABET professional skills. This method is flexible, easy to implement, and can be used at the course level for teaching and measuring engineering
stress. The problem can easilybe divided into the following exam questions. (1) Find the centroid location. (2) Given thecentroid location, find the area moment of inertia. (3) Given the centroid location and areamoment of inertia, find (a) controlling section modulus, (b) bending stress at a particular point,(c) maximum bending stress, (d) maximum tension bending stress, and (e) maximumcompression bending stress. Note that most of these questions were asked for in the originalproblem statement. To create multiple versions of questions 1 through 3a, one or more of thecross-sectional dimensions would need to be defined as a variable. To create multiple versionsof questions 3b through 3e, the bending moment could be defined as a variable. Both

withmicrocontrollers does not mean that students will respond positively. Instructors used the “buzz”about the Arduino to motivate students, by indicating that the students were using a new andpopular technology. Instructor observations of student reaction showed that students were notuniversally inspired by or interested in the technology. This makes sense because the definitionof “cool” is not uniform for engineering students. Assessment was performed with an end-of-term survey of student attitudes toward thecourse and how it affected their career plans. Students were asked whether the use of theArduino platform changed their attitude toward computer programming and electromechanicalsystems. The complete survey is included in Appendix B. Results from
