Projectors and speakers have recently been installed in all the classrooms in the district. Each teacher has been issued a laptop that plugs into a control center so that anything from that laptop (or the document camera that also came with the system) can be projected for the class.
It's a great setup. But it's prone to problems. (Learning a new system...)
Anatomy & physiology class. The teacher left a documentary on the Bubonic Plague. (Not sure how it relates, but I'm just the sub...) Gone are the days when you feed a tape into the VCR and hit play. Way gone.
I logged onto the computer. Inserted DVD. I found the Windows Media Player. (I'm limited to what's already loaded on the computer.) I got it to play. Success.
I turned on the speakers. Got sound.
3rd period arrived. Fingers crossed, I warned them that it might or might not work...
And it played without a hitch. Whew.
To 4th period I said, "Everything worked perfectly last period..."
Famous last words. I know better! I really do.
The projector worked. The video started right up. The audio...
These new installed speakers are going to be the death of me. I have had to show videos in a handful of classes, and the glitch is always in the speakers. I don't know why.
So, the troubleshooting began. I knew everything was plugged in correctly as it had worked the previous period (and I hadn't touched any of the wires). I checked to make sure it wasn't on mute on the laptop. I ejected the DVD and reinserted it. I restarted the computer. (I've had a bit of experience with this, and while the rebooting was last resort, the other fixes fixed it in prior classes.)
Of course, the whole class witnessed this. So, of course I got "helpers".
There's always a couple who come up to "help". I'm sure in many circumstances their help is actually helpful. I know many people who aren't comfortable with the technology. I, however, am.
They suggest stuff I've already done. So, I stand back and let them try. Because they don't seem to believe me when I tell them I tried that.
They played with it to no success. Then I tried one last thing...
There's this knob that switches the audio input from AUX 1 to AUX 2 to CD. It worked just fine on AUX 2 for period 3. For period 4 the fix was to switch it to AUX 1.
And then it worked perfectly for period 5. After switching the knob back to AUX 2. (Then the next day when I had the same group, if the sound didn't work, all I had to do was switch that AUX knob to the other and the sound worked. Go figure.)
Perhaps next time it'll just work...?
Do you step in to "help" when someone is having technical difficulties? Do you need someone to help when you attempt anything with technology?
