InstitutionI. Project BackgroundThis paper discusses the creation and first offerings of a multidisciplinary senior design projectcourse sequence at a regional Hispanic-Serving Institution (HSI). The courses, MultidisciplinaryEngineering Design I and II (GEEN 4301 and 4302), were created as part of supporting activitiesfor an NSF-STEM grant entitled: “Javelina Engineers STEM Scholarships (JESS): Building thePathway for Baccalaureate to Masters Degrees,” or the JESS Program.The over-arching JESS Program goal was to identify academically talented undergraduatestudents across all disciplines offered by the Frank H.

The course entitled “ Bio-inspired robotics” andwas offered as a tech-elective course for our undergraduate students in mechanical engineeringdepartment and robotics engineering. The course focused on legged locomotion in nature and itsdevelopment to robotics engineering. The theme of the course was project-based and we had twogroups of six students. For each team, the project was to design, build and control a bio-inspiredlegged robot (a legged robot that is inspired from nature). One group chose hexapod cockroachinspired robot (also known as Rhex) and another group chose Kangaroo-inspired robot. The classactivities and the homework assignments were centered towards

Over the last five years, the authors(instructors) have taught the ‘Introduction to Materials Science and Engineering’ classexclusively to the non-MSE students (primarily from mechanical, industrial and electricalengineering). From the student feedback obtained during this time, instructors realized the needfor a hands-on project for sustaining students’ interests and keeping them engaged while learningthe fundamental concepts of the field. It is thus necessary that the traditional materials sciencetetrahedron (Figure 1(a)) should be modified to cater to the interests of students from non

and mis-concepts of design do require proper alignment with prevailingconditions on the ground. Undoubtedly, the start of any design course should be preceded byexposure to design thinking and related processes. The paper reviews the role of design inengineering programs, and outlines the current research on how design thinking processes couldbe taught and learned. It explores also the currently most-favored pedagogical model for teachingdesign, namely: Project-Based Learning (PBL). The paper identifies several contexts for PBL,along with some available data on it success. Finally, the paper raises some of the questions thatshould be answered to identify the most effective pedagogical practices of improving designlearning.1

The proposed pedagogical approach is based on systematic learning through evidence-based teaching, knowledge mobilization, and research strategies. In our approach, it is recommended to use two platforms, µVision (simulator) and one microcontroller (hardware), such as Arduino or Raspberry Pi. Raspberry Pi is a small (900 MHz quad-core ARM Cortex-A7 CPU) single-board computer developed by Raspberry Pi Foundation and Arduino is the most popular

Further refinement followed the scale development procedures recommendedby DeVellis (2003). A five-point Likert scale ranging from “not at all important” to “extremelyimportant” was used to measure importance of various activities associated with different waysof thinking, particularly in the context of participants’ EER projects. A definition of the specificway of thinking was provided before the Likert-type questions to provide clarity. The instrumentwas

Full Paper: A Systems Engineering Approach to Conceptual Design in a 1st-Year Engineering Program1st-year engineering students engage in three projects over the course of the fall and springsemesters. In the fall semester students build, test, and present at an exposition an Arduino-basedgame. While students are provided the design for the game, they are strongly encouraged tomake creative modifications. Following this, students complete a reverse engineering activity ona simple household appliance or medical device. The result is a CAD model of the device and adetailed report, typically of about 40 – 50 pages. Students work in teams of three or four on bothprojects.In the spring semester work consists of a
