So who is right? As usual, the truth is complicated.
The point of contention with worksheets seems to be that they are a one-size-fits-all method that ask little of the teacher other than to stand at a copy machine for a few minutes to produce one-size-fits-all pages that drill-and-kill various standards and skills.
While I sympathise with the arguments, I believe worksheets, when properly designed and implemented, have a place in the classroom. And while I also believe that there are many good teachers using worksheets from textbook supplementary materials, I also think that when you create a worksheet specifically with your own class context and students’ needs in mind, it is far more useful. There are plenty of times when I choose to use content I haven’t created, but when it comes to skill practice, I want my students to have something I designed specifically for them.
Thankfully, there is a tool that allows me to create worksheets that are infinitely customisable as well as ones that can easily be differentiated for students with different educational needs. That tool is Google Drawing.
