Why should I use a feedback survey?
It's not like you HAVE TO, but it sure can improve many aspects of the class and your understanding of it. First of all, allowing students to openly and honestly bring their opinions to the table is going to relive them, make them feel heard and noticed, and give a general sense that they're being taken care of. Especially in the online classes times, we live in, it's paramount to check on everyone and ensure the wellbeing of your students.
Are the templates customizable?
They are. These survey templates are also free, which is just, you know, so crazy. To get and keep your student's attention, it's paramount you understand them and what they feel attracted to. For example, don't use "paramount". Play around with the fonts, colors, questions, and design to make it feel targeted to them and not any other class across the globe. They'll love you for it. Or maybe not, but at least you're trying.
How do I use it?
In this case, it's really simple. Chances are you have a list of every student's phone number or email. Just forward the form directly to them and get ready to be astounded (don't use this word in the form) by the results and how easy they're collected and analyzed. The future is now, old man.
