College of Engineering and Science

Living with the Lab
  • Each student owns their own “lab” consisting of
    • a laptop
    • tools (multimeter, dial caliper, wire strippers, . . .) $80
    • software (Mathcad, SolidWorks, MS Office)
    • a robot kit (the Boe-Bot) to provide a personal “lab” $100
      • Student owned labs provide a way to boost hands-on learning beyond what is possible using traditional university laboratories

Freshman Projects

Laboratory

Two classrooms designed to support the curriculum

(40 students, 24 students)

Classrooms allow us to easily switch between lecture, laboratory and shop activities within a single 110 minute class period.

Seven “Threads” Define the First Year Experience

  • SYSTEMS – one major project per quarter
  • ELECTROMECHANICAL – breadboarding, sensors, control
  • FABRICATION AND ACQUISITION – shop activities; locate, specify and purchase components
  • SOFTWARE – Excel, Mathcad, SolidWorks, Programming
  • FUNDAMENTALS
    • electricity and DC circuits
    • conservation of energy
    • basic chemistry and electrochemistry
    • conservation of mass
    • least squares fitting to calibrate sensors
    • statics
    • engineering economics
  • COMMUNICATION – formatting problem solutions, oral presentations, writing assignments
  • BROADENING ACTIVITES
    • global and societal issues
    • professional society meetings and student functions
    • teamwork and creative problem solving techniques

Course sections are coordinated with common assignments and exams

  • 433 students were taught in fall 2008
    • 14 course sections (4 honors)
    • 8 faculty members

CONCLUSION: We have implemented a six semester hour, technology-enabled, project-based experience that impacts over 400 first-year engineering students each year.

  • Strong analytical skills
  • Practical ingenuity & creativity
  • Good communication skills
  • Business, management skills
  • High ethical standards, professionalism
  • Dynamic, agile, flexible & resilient
  • Lifelong learners
  • Able to put problems in their socio-technical and operational context
  • Adaptive leaders

2008 Freshman Design Expo

May 7, 2008

slide23

College of Engineering and Science

History

  • In 2002 we offered a pilot robotics-centered curriculum to 30 students
  • In 2006 we received $498,000 NSF CCLI grant to expand the curriculum to all engineering students
  • In the fall of 2007 we implemented the curriculum for all students

Why?

  • We wanted freshman design to be more than mousetrap cars and straw bridges
  • We wanted to progressively build skills and competence so that freshmen could implement significant projects
  • We wanted to make students more innovative
