So I had a room full of fifth grade students with a lesson plan on search engines. We were going to compare search results from different engines. We were going to learn how to refine our searches. We were not going anywhere because the Internet connection had gone down.
So I quickly checked with the librarian and moved my lesson offline. We selected books from the reference cart: dictionaries, atlases, encyclopedias and records books. I then gave students the same search queries from the lesson. We still compared results and discussed why some sources provided better results. We even contemplated if other libraries would have better selections or unique resources.
The trick to any offline lesson plan is understanding what concepts digital tools are built upon. Digital search is still the search for and analysis of information. For centuries, people have dug through catalogs of information in analog format. If students can perform the task analog, then transfer the concept to a digital platform, they will have a better understanding of the process.
So the next time the Internet goes down, don't panic. Demonstrate to students it isn't the electronic tool that impacts the quality of the work, but the skill of the person wielding the tool.
