I have started teaching using MS TEAMS since term 2 (2019-2020) for Secondary classes . Such a rich platform is definitely an effective, efficient teaching tool. TEAMS, " all-in-one hub" , is a great means that gives teachers the chance to build up a collaborative classroom and create an interactive learning environment smoothly... However, many challenges might hinder the learning process such as electricity and internet connection problems... Not to mention attitude problems (most parents / students show a lack of interest and take online learning lightly)...
