I have been experimenting with creating custom search engines (using Google's CSE tool) for educators/parents/students. I've started with 2 for Math content (lesson plans, practice problems etc) - one for K-8 Math resources and one for High School Math. I've put up the links here (on my blog)
I'm aware that teachers have access to several good sites for their subjects, but how do you look for material within
a bunch of sites? A tool like this customizes your search, so that you focus on relevant sites when you search (and provides some value-add as well) and you don't have to wade through tons of irrelevant hits that show up in regular google searches.
It would be great if interested teachers in this august forum could give these 2 CSEs for Math a try. Just use them the next time you need to look for some Math stuff. Please do leave me feedback - these are still works-in-progress, so your inputs will be valuable.
Also if anyone here would like to collaborate with me to create CSEs for all subjects (I'm working on other subjects too), do drop me a line!
