I found that the Edutopia website has a nice summary of a lot of the current trends, such as flipped classrooms. I would go there if you want a group of summary of what people are doing. Your question is pretty general so it is hard to know if you want something more specific.
If you allow your students to be on-line during lectures or seminars, then you can either have them use their ICTs as part of their learning process, or you allow them to spread their attention and so hinder learning. Many students see classroom activity as 'additional to' the other things they do--much of which is online. And ICTs can be addictive. So the challenge is to channel existing behaviors towards learning outcomes--perhaps through directed information searches, fact checking, time-constrained situation analyses and so on--that rely on the students' pre-existing proclivities. It's not so much going with the flow, as channeling it. Good luck.
ICTs can be used to engage students in the learning process in many different ways. Regarding mathematics education you could use a Dynamic Geometry Software (DGS) or Computer Algebra Software (CAS), but of course, you have to design teaching/learning materials or find some already existing and adapt them according your needs. Maybe the following article can give some insights.
