Hello Fateemah,
Digital tools that provide/improve access to education will have the most impact on the students, these can be computers, projectors, interactive boards etc.
You can also introduce programs that teach digital skills to the students, these can be programming, graphics design, digital marketing, CAD etc.
The schools can also use digital solutions to further their reach and presence on the internet by using social media, blogging, having a website etc.
Hope this helps.
#Peace ✌
