Dr. Robert Richards received the Ph.D. in Engineering from the University of California, Irvine. He then worked in the Building and Fire Research Laboratory at NIST as a Post-Doctoral Researcher before joining the faculty of the School of Mechanical and Materials Engineering at Washington State University. His research is in thermodynamics and heat and mass transfer. Over the last five years he has become involved in developing and disseminating research based learning methods. He was a participant in the NSF Virtual Communities of Practice (VCP) program in Spring, 2013, learning research based methods to instruct thermodynamics. More recently he introduced the concept of fabricating very low cost thermal fluid experiments using 3-D printing and vacuum forming at the National Academy of Engineering’s Frontiers of Engineering Education in October, 2013. He is presently a co PI on the NSF IUSE: Affordable Desktop Learning Modules to Facilitate Transformation in Undergrad¬uate Engineering Classes, High School Recruitment and Retention.

Abstract

A Remote Access Laboratory for Fluids Education in Mechanical Engineering The purpose of this research was to develop a teaching module specifically for distanceeducation that would strengthen student understanding of flow through a venturi. An experimentwith web based control of and data acquisition from a model venturi nozzle was developed andimplemented into junior level engineering classes. The intended use was for distance educationby both instructors and students at satellite campuses. Instructors of lecture courses can use theexperiment to bring demonstrations of real devices and active learning assignments intoclassrooms remote from laboratory facilities. The method employed in the research depended onthe integration of the remote venturi nozzle experiment into two classes and assessment oflearning outcomes via Pre and Post Testing and student survey. The web-based venturi nozzleexperiment was implemented first in a junior level fluid mechanics course, as an active learningexercise concerning Bernoulli’s equation. In this class the instructor ran the web-basedexperiment. A pre assessment quiz was given to students after a lecture on Bernoulli’s equationbut before running the online experiment. A post assessment quiz followed the active learningsession with the remote lab. The experiment was then used in a junior level laboratory course, inwhich a small group of students ran the web-based experiment themselves. A survey was usedto assess the outcome of the experiment by the pilot group. Two major conclusions can be drawnfrom the implementation of the web-based lab. First, the pre and post test indicated that studentsshowed significant improvement in conceptual understanding after exposure to the web-basedlab in the junior fluid mechanics course. Second, the student survey indicated that only minoroperational changes were needed for students to successfully operate the web-based lab. The labis now being operated remotely by students at a satellite campus as part of their juniorinstrumentation course. Assessment of learning outcomes achieved by remote users compared tohands-on users is performed through analysis of laboratory reports.
