Yes. Many high schools and universities already use SciNote. Electronic lab notebooks (ELNs) are becoming standard practice in many labs, so it is therefore recommended that high school students already start using them and become aware of the importance of documenting their work in a structured way.
Specifically for that, we have also created a Classroom Plan for Professors and Students.
Additionally, you can read the Ed Tech Round Up’s review by Michael Karlin on how SciNote can be used for high school science class specifically.
