OpenSciEd is made possible because of the generosity of philanthropic partners. These foundations are interested in the impact of their funding and ask that we provide data regarding the number of teachers registering to access OpenSciEd. Additionally, OpenSciEd provides the materials in a manner that allows teachers to download the curriculum into their own repository, rather than having to log in every time they wish to use the material. So, if a teacher chooses they only have to login once to download the full program.
