If the barrier to accessibility is such a problem, why perpetuate it by throwing your students against that wall?

The journals' business model does suck, but you're delivering students to a paywalled garden to retrieve information on what amounts to a proprietary topic. You have the power to change this by redirecting the students' attention elsewhere, either by loosening requirements or changing topics to one with more accessible research...

They choose the topic. I'm fine with anything in biology, medicine, chemistry, and even some social science topics. Some of them run into trouble and others don't depending on what they choose.

I've considered removing the assignment a few times, but there's no skill more essential to success in science than the ability to synthesize different research articles into a coherent whole. I wouldn't feel like I was doing my job if I stopped assigning it.
