6 L OUISIANA T ECH U NIVERSITY MECHANICAL ENGINEERING PROGRAM 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 College of Engineering and Science

7 L OUISIANA T ECH U NIVERSITY MECHANICAL ENGINEERING PROGRAM 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 L OUISIANA T ECH U NIVERSITY MECHANICAL ENGINEERING PROGRAM Seven “Threads” Define the Freshman Experience 1.SYSTEMS – one major project per quarter 2.ELECTROMECHANICAL – breadboarding, sensors, control 3.FABRICATION AND ACQUISITION – shop activities; locate, specify and purchase components 4.SOFTWARE – Excel, Mathcad, SolidWorks, Programming 5.FUNDAMENTALS electricity and DC circuits conservation of energy basic chemistry and electrochemistry conservation of mass least squares fitting to calibrate sensors statics engineering economics 6.COMMUNICATION – formatting problem solutions, oral presentations, writing assignments 7.BROADENING ACTIVITES global and societal issues professional society meetings and student functions teamwork and creative problem solving techniques College of Engineering and Science

21 L OUISIANA T ECH U NIVERSITY MECHANICAL ENGINEERING PROGRAM College of Engineering and Science Questions? 2008 Freshman Design Expo May 7, 2008

22 L OUISIANA T ECH U NIVERSITY MECHANICAL ENGINEERING PROGRAM 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
