In working with our Advisory committee, they wanted to include all information about entomology teaching; that includes some materials that are in journals with paywalls. Materials in journals often include evaluation information or real-world use information; that's important. The materials in NSTA journals are especially good; while initially you may hit a paywall, if you create a free login most of them can be downloaded for free. For journals that don't offer free access, a library is your best bet. We can't tell you how to get around paywalls.
