 Okay, so we'll learn how to do one of these Scantron cards. We're going to do a greater test here, or a quiz in this case. So the first thing you want to do is make a key. So there's a Scantron card with the key. And then you can see here there's some keymarking instructions. So if you just mark five, it just prints the score. If you mark two and five, it prints the score and verifies the answer in an alphabetic way. If you push, or if you mark two, three and five, it prints the score and verifies the number in a numeric way. So the way I do it is just two and five, because my quizzes and tests are, the answers are A, B, C, D. So since we want it alphabetic, we'll do just 25. So we'll mark that, so there, and there, and so now hopefully you can see that it's there and there right at the top. And above the five, there, it says key. So okay, so now what we want to do is make sure this says print left. So there's the switch here that you can flip on and off kind of right. So print left or print right. I always do print left. And then I push the power button, you get that noise, okay, yeah. And then what we're going to do is first you feed the key through, so the thing that you just made, right? And then you'll hear it, and then you'll see here, it'll mark the number of questions that you have. In this case, it's 30. Okay? So that would be the total number of correct answers. Or we could use the other side. Yeah, the other side. So what you would do then is you would push it through once, and then flip it over, and then push it like that, you know, and then it'll catch it. So let's just do some of these quizzes. We're going to have to run the key again. That's all right, though. Okay, so you heard it click, right? They did really well. Got a 30. This was a take-home quiz, so everybody better be getting a 30 out of 30 on it, so you can hear that person didn't get it. Oftentimes, in real quizzes that aren't take-home, you'll hear a lot of do-do-do-do-do-do-do, and that's meaning, that means that they're getting things wrong. So here you can only hear it, like that one, did you hear? Yeah. Definitely. Uh-huh, yeah. So normally they're much more dramatic. They're like do-do-do-do-do-do-do-do. Okay. Are there any... There's everything. Yeah. Are there any questions? No. Can I kill the video? Oh, yeah, yeah. Yeah. Do you think you got it? Yeah, okay. Okay. Yeah, okay. So, okay. First, you prefer the key, then you just click here, and then you run your... And then you print it out. Uh-huh. So there's another sheet, which I haven't shown you, but we can do another video of that, and that can give you like a readout of your students' overall average scores, the overall number that they got right, and the overall number, the absolute number, yeah, the absolute number of each question that they got wrong. You don't have to. Uh-huh. No, you don't have to. For the final, they're going to ask you for it, yeah, that's the point. Also, at the end of the semester, usually, they require you to... Just on the final. But for yourself, you know, if you like that thing, then do it.
