Louisiana Tech University College of Engineering and Science  Criterion 3H (ABET EAC): engineering programs must instill within students “a recognition of the need for, and an ability to engage in, life-long learning”  Difficult to measure how well an engineering curriculum instills the attribute of life-long learning

Louisiana Tech University College of Engineering and Science  Informal mode of learning takes place as individual learns to accomplish a task. (Formal mode also important to lifelong learning.)  “Bigger picture” (global and societal issues) may motivate passion for lifelong learning.  Several surveys show alumni recognized need for increased exposure to professional societies and professional literature.  Confidence comes through practice.

Louisiana Tech University College of Engineering and Science  PROBLEM: Students didn’t understand how to apply engineering skills to solving real-world problems.  AIM: Implement a fast-paced, threaded curriculum that boosts experiential learning and creates dynamic learners with a “can-do” attitude.  STRATEGY: Replace traditional curriculum with integrative, project-based learning combining engineering theory with engineering practice.

Louisiana Tech University College of Engineering and Science  Students are required to purchase:  A laptop and selected software  A set of critical tools and supplies for about $70 (multimeter, dial caliper, solder, etc.)  Their own personal “lab” for $110 (a Boe-Bot kit from Parallax Systems; volume discount price)  Kit provides a mechanism to boost hands-on learning beyond what is possible using traditional university laboratories

Louisiana Tech University College of Engineering and Science  Traditional  Focus on academic learning and software skills  Project-Based  Greatly increased hands-on activities to support academic learning  Focus on instilling attributes of The Engineer of 2020  Requires purchase of laptop, software, Boe-Bot, and tools, but no textbook  Instructional materials and assignments posted on course website

Louisiana Tech University College of Engineering and Science  ENGR 120: Fabrication and testing of a centrifugal pump (3 weeks)  Design impeller blades; fabricate pump housing  Pump water at varying heights to determine efficiency of the pump  ENGR 121: Monitor and control salinity and temperature of water in a “fish tank” (10 weeks)  Fabricate conductivity sensor and RTD sensor  Use Boe-Bot to monitor sensor readings and control solenoid valves and heater to correct readings  ENGR 122: Open-ended design project (5 weeks)  Use a Boe-Bot and at least one sensor to solve a problem  Student teams from all classes compete for awards

Louisiana Tech University College of Engineering and Science  Closed loop control of temperature and salinity in a small tank  Initially, teams of 2 later turning into teams of 4

Louisiana Tech University College of Engineering and Science

Louisiana Tech University College of Engineering and Science  Independent learning in computer programming and 3D modeling skills  Locating and specifying parts and components  Attendance at professional society meetings  Development of troubleshooting skills  Open-ended design  Consideration of global and societal issues

Louisiana Tech University College of Engineering and Science

Louisiana Tech University College of Engineering and Science  ENGR 120: 17.3  ENGR 121: 22.5  ENGR 122: 19.0

Louisiana Tech University College of Engineering and Science  Fifteen activities including:  soldering, layout, assembly, bending, sawing, drilling, milling, using a scale, using a lathe, rapid prototyping, cutting threads, using a caliper, using a multimeter, implementing circuits, and writing PBASIC programs

Louisiana Tech University College of Engineering and Science  ENGR 120:  Old: 13.5  New: 63.4  ENGR 121:  Old: 3.3  New:  ENGR 122:  Old: 26.7  New:  Student t-test shows application means for ENGR 120 new curriculum to be significantly greater (p = ); differences for ENGR 121 and 122 are highly significant (p = ; p = , respectively)

Louisiana Tech University College of Engineering and Science  Outcomes common to both old and new curricula include:  Using solution format, working collaboratively, presenting results (written), presenting results (oral), generating 3D models, creating tables and graphs, locating specs and prices, performing linear regression, using Mathcad, using Excel, creatively overcoming difficulties, working toward goals, developing technical tools, planning to develop new processes, explaining trends, and assessing implications of a current societal concern

Louisiana Tech University College of Engineering and Science  Students express more confidence in completing common course outcomes in the new curriculum…  ENGR 120: 12 out of 16 common course outcomes  ENGR 121: 13 out of 16  ENGR 122: 11 out of 16  Student t-tests show that students felt a greater confidence in their ability to complete common course outcomes with the new curriculum (ENGR 120: p = ; ENGR 121: p = ; ENGR 122: p = )

Louisiana Tech University College of Engineering and Science  Students were required to use at least one sensor for their design projects.  No instruction was provided on sensors; students had to locate, read, and understand specifications and sample programs with little or no help from instructors.  Average number of times students reported using sensors during academic year: 6.33 times

Louisiana Tech University College of Engineering and Science  Focus group meetings were conducted by an external evaluator in Spring  Sample responses:  “I like that they (the instructors) didn’t always tell us what to do – we had to figure it out on our own.”  However, “there was always someone there to help – faculty and classmates.”

Louisiana Tech University College of Engineering and Science  Project-based first-year engineering curriculum at Louisiana Tech seeks to:  build a spirit of creativity and innovation in our students  provide experiences that foster the attributes of the Engineer of 2020  Self-learning activities increase opportunities for “informal mode” learning and for building confidence.
