Individual Data Acquisition and Experimentation in Undergraduate Mechanical Engineering LaboratoriesUndergraduate teaching laboratories in mechanical engineering curriculum are traditionallygroup-oriented courses with activities centered on large, one-off experimental apparatus. Thepredominance of single-instanced experimental laboratories is largely due to the balancebetween having sufficient curricular diversity and the cost and maintenance constraints of labinstructors and support personnel. This work summarizes the experiences over the last two yearswhere a model of all individually-based data acquisition and experimentation laboratoryactivities was established in two separate teaching laboratory courses: mechanics of materialslaboratory and dynamic and controls systems laboratory. All students used self-owned personallaptops combined with student-owned low-cost universal serial bus data acquisition (USBDAQ) devices for interfacing with each individual experimental station. The experimentalactivities would be changed out each week but with the thread of commonality being that thesoftware programs written for the USB DAQ device from the previous week’s activity wereemployable in subsequent activities. Since data was acquired on an individual basis, individualreports recounting the laboratory procedures, results, and discussion were submitted and graded.Assessment of this approach was performed via anonymous student course evaluation surveyscomparable to previous traditional group-experimentation laboratory courses where similarsurveys were given. The potential ramifications of this model adoption on undergraduateteaching laboratories will be discussed in relation to increased student engagement anddepartmental resource allocations.
