For my agriculture mechanics lesson, I taught students the three steps involved in connecting PVC pipe into fittings. I started the lesson with explaining the steps and demonstrating to students in a "teacher says, teacher does" format.
The first step was priming the PVC and the fitting for the connection. I started with asking if everyone has their PVC and fitting before beginning and explained the process of priming while doing so. As it was drying I asked the students why priming is important, and what might happen if it is not primed.
The second step was to cement the two pieces. This had to be done quickly, as the cement dries quickly. Both pieces needed to be coated thoroughly, but not excessively. The final step was to connect the two pieces together and give them a slight twist. This allows the cement to spread evenly and remove air from between the two pieces. After demonstrating, I had a student do it themselves while the other students "coached" them through it.
In a classroom setting, students would be able to each have their own work station, and could build their own project, but this exercise was just for practice. I had to do a retake of the video due to the lid sticking on the cement very tightly. Despite this, I'd say our objective of connecting PVC pipe and understanding the process was completed.

It sounds like this went really well, Ryan! You're going to have to teach me a thing or two about plumbing the next time we get together!
ReplyDeleteRyan, I really like how you incorporated questioning into your demo to remind students of the "why" of the activity. Having students work together to demonstrate the skill, as well as teach/coach and assist each other not only aids in engagement, but helps elevate learning the skill to a higher order of Bloom's taxonomy.
