As a teacher, you must also know what causes students to be less motivated, maybe there is no support from family, bullying or certain mental conditions. After knowing this, the teacher will easily determine what way to motivate the students concerned.
Another way that teachers can give to motivate their students is by way of “Class Recreation”. Make time once a week. Invite students to watch movies that inspire their motivation. Films related to the struggle to achieve goals, or just educational entertainment.
