Teachers can use visual aids like PowerPoint presentations as a complementary tool in order to excite discussions among students. They can also be allowed to use electronic devices to record observations. This way, each one of them gets to participate without necessarily feeling shy. Teachers also get to monitor student's progress and see where to enhance.
Apart from that, science instructors can also break the norm by engaging students in interractive games as a fun way of grasping scientific concepts which they will not forget easily.
