Motivation Behind Educational Changes
![Page 14: Educational Research on a Platform for Learning TM](https://reader036.fdocuments.in/reader036/viewer/2022070414/56814dd3550346895dbb35d5/html5/thumbnails/14.jpg)
The Global Need
Knowledge integration should be at the core of an engineering education...”
Engineers must be enablers to "wealth creation" …through innovation… rather than simply be a commodity on the global market
Joseph Bordogna, NSF Deputy Director
![Page 15: Educational Research on a Platform for Learning TM](https://reader036.fdocuments.in/reader036/viewer/2022070414/56814dd3550346895dbb35d5/html5/thumbnails/15.jpg)

In the Beginning…
There was Sparky!
![Page 20: Educational Research on a Platform for Learning TM](https://reader036.fdocuments.in/reader036/viewer/2022070414/56814dd3550346895dbb35d5/html5/thumbnails/20.jpg)
Sparky Made ECE Fun!But it ended there …
Until we introduced layering on the robot
It grows and matures as the student does
☺ The fun continues

– Oregon State, Texas A&M, U Nebraska, Linn Benton Community College
• 300 Students using Mechatronics Platform• 3 Journal and 7 Conference Papers• Three Active University Partners – We look
forward to adding FIT• Kids attracted to engineering because of
TekBots

Challenge ProblemsCreating Innovation Opportunities
Lab Title Challenge Question
Robot Gymnastics Speed and Accuracy Challenge: Set your TekBots robot to make as many laps as possible without straying from a defined circle in a minute.
Ohm’s Law in Practice
Make a ‘Resistor’: Build a PWM from a 555 timer chip that models a resistor in series with your motors. Make a simple cruise control.
KVL: Friend or Foe? Exploring Power: Explore why power consumption is important on cell phones, Martian rovers, and vacuums.
Working Together Works
All Powered Up: Explore the differences if any of various series/parallel circuits made from motors and batteries.
Transistors Can you Feel the Noise: Build a simple amplifier and inspect the noise on your robot’s motors. Find how to reduce this noise.
Go Towards the Light Reverse Psychology: Can you make your light-loving robot scared of the light?

Activating Learning in the Classroom
Roger Traylor• What is Active Learning? – Learner is the driving force, instructor is
facilitator– Can include cooperative learning, hands-on
instruction
• Why use it?– Students fall asleep in lecture (duh!)– 90 yrs of research, 600 studies show it works– Big classes need it badly– How it can be done? – How can I cover the material?
