Ubiquitous Hands-On Learning Using Mobile Laboratory Instrumentation in the era of MOOCs
MORGAN STATE UNIVERSITY
Outline
This presentation will provide examples of how mobile learning and MOOC-like environments work together to: 1) Level the playing field and make higher
education accessible to more engineering students; and
2) Disrupt the traditional teaching models while continuing good quality, research-based university education.
Growing the Future, Leading the World
Introduction
• The use of technology in the classroom has greatly impacted engineering education during the last 15 years.
• BUT, traditional method of teaching, i.e. lecturing or “chalk-and-talk” is still dominant.
• Instructors need to deliver course content that students can access from anywhere at any time.
• WHY : today’s students expect it !!!

Mobile Hands-On Learning
Hands-On Learning: Anywhere, Anytime. New portable devices
replace a rack of equipment that is equivalent to $5Kto $10K
Question: Can these new portable devices be used in MOOCs ?
Answer: YES !!!

Models of Mobile Hands-On Learning
1. Mobile Studios: Integrated Classroom Environment (RPI, Rose-Hulman)
2. Labs Integrated into Lecture-Based Courses (Georgia Tech)
3. Lab Courses with Student-Owned Devices (Virginia Tech)
4. Online Lab Courses (Morgan State University)
5. Circuits Lab MOOC-Coursera
Growing the Future, Leading the World
Model #1: Mobile Studio Model (RPI)
Growing the Future, Leading the World
Studio classroom: Flipped Classroom active, collaborative/team learning
Hands-On,Mobile, Inexpensive
PSpice,MATLAB,LabVIEW,etc.
Theory, BackgroundFundamentals
Model #2: Labs Integrated into Lecture Courses (Georgia Tech)
TESSAL Center Teaching Enhancement via Small-Scale Affordable Labs Funded by an NSF CCLI Phase 2 Grant www.ece.gatech.edu/research/tessal/index.html
Goal: improve undergraduate learning by integrating 2 to 3 experiments into a wide range of ECE lecture-based courses Active Learning
Scale: ~2500 students/year, ~25 instructors/year
Growing the Future, Leading the World
Model #3: Lab Courses with Student-Oriented Devices (Virginia Tech)
Lab-in-a-Box (LiaB) Students purchase Lab Kit $200
Plus Laptop or Tablet PC Students conduct 10 experiments
in circuits outside of the classroom and demonstrate the operation of the circuits in an open lab environment.
Scale: 700 students / semester Developed an online circuits lab
course in summer of 2012.

Summary: Mobile Hands-On Learning
Model 1: In Studio-Style Courses low-cost studio-style learning environment,
more thoroughly integrates theory and practice
Model 2: In Lecture-Based Courses enhance learning of difficult concepts, low
threshold
Model 2: In Lab Courses give flexibility to students, alleviates
department resources
Model 4: Online Lab Courses allow students to enroll in ECE online courses
and complete them from anywhere at anytime

Frontiers in Education FIE 2013Center for Hands-On STEM
Portable Instrumentation Specs
• MyDAQ Specs• The platform includes a data acquisition engine that students can use to
measure two differential analog input and analog output channels (200 kS/s, 16 bits, ±10 V). The eight digital input and digital output lines (3.3 V TTL-compatible) help students interface both low voltage TTL (LVTTL) and 5 V TTL digital circuits. NI myDAQ supplies enough power for simple circuits and sensors with +5 V, +15 V, and -15 V power supply outputs (up to 500 mW of power). The isolated 60 V DMM can measure both AC and DC voltage and current as well as resistance, diode voltage, and continuity.
