At my school, access to technology (i.e., laptops or computer labs) is not always equitable. Some teachers have nearly 1:1 access, while others (like myself) have to schedule weeks in advance for access -- and even then, can only schedule three days in a row.
Thankfully, there are ways to teach our students 21st Century Skills (such as critical thinking, etc.) without having to possess a 1:1 environment. This article gives some examples.
From the website: "OER (Open Educational Resources) Commons a public digital library of open educational resources. Explore, create, and collaborate with educators around the world to improve curriculum."
OER contains access to many different educational resources that can be found on the web. You have the ability to search by subject, grade level, and standard(s). In addition, teachers can add resources to the "commons" through a resource builder, a lesson builder, or a module builder.
While not all of the content on the site is spectacular, it definitely has potential!
