Two Ways to Use Pictures in Formative Assessment

When I taught a computer repair class for high school students there were two ways that I consistently used pictures and diagrams in formative assessment.

Formative Assessment With Images on Formative
Every week I would have students answer questions based on a diagram that I upload to Formative.com. I like using Formative.com for this purpose because I can add multiple questions to the same diagram. Students know exactly which part of the diagram each question is referring to because the questions appears when they click the diagram. 

Students Documenting Processes With Pictures
One of the first hands-on activities that my students would do every semester was to disassemble and then reassemble some old desktop computers. Originally, I was going to have students draw diagrams throughout the disassembly process. That proved to be time-consuming and inaccurate (sloppy drawings, poor penmanship). So I switched it up and had them start taking pictures on their phones then labeling those images before sharing them with me via Google Classroom.

The act of photographing and labeling wasn't graded (other than done/ not done). I wanted to see which students could recall and document well and which still needed help with the process.

Everything You Need to Know About Computer Monitors

Back when I taught computer repair we got all kinds of old computers and monitors donated to our classroom. One of the seemingly never-ending challenges was matching monitors with computers. That was particularly true when my students would be confronted by units that had only VGA or DVI inputs. And there was always an conversation that included phrases like "this monitor is so old" and "can this monitor work with this input?" All that to say, I ended up spending time at the start of the course explaining various monitors and connections. I wish I had had Monitors Explained by PowerCert Videos back then. 

Monitors Explained by PowerCert Videos provides an excellent overview of monitor types, panel types, refresh rates, contrast ratios, and response time. 



Applications for Education
This video is obviously helpful for students who are in some type of computer repair class. It's also good to watch from the perspective of becoming an informed consumer before purchasing your next computer monitor.
