Conclusion

Future
Study

The users need to be
involved in a lot of
speculation in the buzz
of digital and
education.

Lots of efforts into
materialising the
changing for T and L to
take place around the
technology.

Ensure technology 3.0
won’t do any harm to
the users.

Teachers/ educators
need to discuss and
scrutinise their
practice and make
explicit pedagogies
underpin to meet the
current demands
