During this year's NACAT held in Québec City, I was honored by my peers and it was one of the highlights of my career.
I am absolutely honored to have been chosen educator MVP at NACAT 2013! For the first time ever, I was speechless.
Using smart phones in the classroom?
One of the biggest changes I have seen in the last year is that some schools are now asking students to bring their smart phone to class so it can be used as part of the information and educational process. It was a short time ago that all I heard was that phones in the classroom were a bad idea. Why is this happening? I think the fact that smart phones are so popular and they are so powerful that some school systems are thinking that they can be used instead of having the school purchase additional computers. I think the use of these devices need to be monitored and controlled but their use, to me, seems like a logical move to improve learning using a device that students love.
Scan tool on a smart phone
One of the ways that a smart phone can be used in
the classroom and beyond is using the smart phone to access the vehicle through the DLC using a Bluetooth adapter. One that I purchased, (ELM 327) costs about $10 for the Bluetooth adapter and then $4.99 for the iPhone app (Engine Link). Therefore for less than $20, I now have a working global (generic) scan tool that fits in my pocket. The functions of this tool include:
1. Read diagnostic trouble codes, both generic and manufacturer-specific, and display their meaning (over 3000 generic code definitions in the database).
2. Clear trouble codes and turn off the MIL ("Check Engine" light)
3. Display current sensor data, including:
4. Engine RPM
5. Calculated Load Value
6. Coolant Temperature
7. Fuel System Status
8. Vehicle Speed
9. Short Term Fuel Trim
10. Long Term Fuel Trim
11. Intake Manifold Pressure
12. Timing Advance
13. Intake Air Temperature
14. Air Flow Rate
15. Absolute Throttle Position
16. Oxygen sensor voltages/associated short term fuel trims
17. Fuel System status
18. Fuel Pressure
