  1. College of Engineering and Science Freshman Engineering Overview of the Living with the LabCourse Sequence

  2. College of Engineering and Science Louisiana Tech 10,607 students Seven Engineering Programs 1,123 students

  3. Motivation College of Engineering and Science Challenges • Population growth • Fresh water shortages • Energy demands • Aging infrastructure • Global warming • New diseases • Security Source: Dr. Wayne CloughEngineer of 2020 Project ASEE Presentation, June 2005

  4. Breakthroughs College of Engineering and Science Sustainable Technology cheap technology +“flat” world +more people =accelerating rate of change We believe that technology-enabled, project-based education helps build these attributes in our students. • 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 Microelectronics/ telecommunications Nanotechnology Biotechnology/ nanomedicine Logistics Source: Dr. Wayne CloughEngineer of 2020 Project ASEE Presentation, June 2005 Photonics/optics Manufacturing

  6. 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

  7. College of Engineering and Science 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. College of Engineering and Science 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 • BROADENING ACTIVITES • global and societal issues • professional society meetings and student functions • teamwork and creative problem solving techniques

  9. College of Engineering and Science First Half of ENGR 120

  10. College of Engineering and Science ENGR 120 Project: Fabrication and Testing of Centrifugal Pump teams of 2 students, turning into groups of 4 for pump performance testing

  11. College of Engineering and Science • Approximate cost per pump = $5 • Two students can fabricate the pump in about 2 hours

  12. College of Engineering and Science 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

  13. College of Engineering and Science ENGR 121 Project – The Fishtank

  14. College of Engineering and Science ENGR 122 – Innovative Product Design

  15. College of Engineering and Science No Textbook – Course Materials are on Web www.livingwiththelab.com

  16. College of Engineering and Science Course sections are coordinated with common assignments and exams • 433 students were taught in fall 2008 • 14 course sections (4 honors) • 8 faculty members

  17. College of Engineering and Science Student Notes Instructor Notes Several hundred pages of notes define the courses.

  21. Questions? College of Engineering and Science 2008 Freshman Design Expo May 7, 2008

  22. 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
