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.

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 !!!

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.
