>>Narrator: Darrell McClendon reinforces lessons while making a
personal connection with each student every day.
>>Darrell: One, the kids have to give me a firm handshake.
If they don't give me a firm handshake and look me in the eye,
they have to go back to the end of the line and start all over again.
[Laughing] See ya!
See ya!
>>Darrell: It's a respect kind of thing.
What I normally do here is I ask them a question about engineering,
and they can't come into my room
until can they answer the question right.
And things that I'm asking them now they learned three, four weeks ago.
Most kids don't retain it, you know, more than however long they need it
for the test, but they know they can't get into the room without it.
>>Oh, oh, I feel for you.
I feel for you.
>>Darrell: I do it as a little fun, and I do it as a review
for the concepts, because I try to teach them
that the engineering concepts that we learn and we do
in the class aren't all that difficult.
>>Power good morning.
>>P equals...
>>No, I'm over here.
That's what I'm talking about.
>>Darrell: I firmly believe that you've got to find some way
to connect with the kids.
>>The color is black.
What is the number?

>>All right.
Say it with some authority.
My sister, how are you?
>>Good.
