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

7
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.
8
Seven Threads Define the Freshman 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

ENGR 120 Project Fabrication and Testing of
Centrifugal Pump
teams of 2 students, turning into groups of 4 for
pump performance testing
11
  • Approximate cost per pump 5
  • Two students can fabricate the pump in about 2
    hours

12
ENGR 121 Project The Fishtank
  • Closed loop control of temperature and salinity
    in a small tank
  • Teams of 2 initially later turning into teams of 4

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

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
