There is no exact blueprint for successful teaching. Generally, no two teachers are identical in their style of teaching. When it comes to managing a classroom, most teachers who are novice learn by hit and trial method. One could also take advice from and follow those who have walked and stumbled-before while treading the same path. One smile, a pat on the back can make all the difference in the world. It plays a major part in bonding and attachment with the students. As you meet your students, look them in the eyes, greet and smile.
Be open and willing to learn at all times. Teaching tour provides many chances to learn. Try and attempt to hone the teaching skills through the day to day experiences. Also, prepare well designed and engaging lessons. It's a futile attempt if the lesson is shoddily planned with fewer hands-on learning.
Constitute rules, convictions, accountability and procedures on the first day of school. Don’t behave like a dictator but be firm, fair and consistent. Adding a dose of fun and accountability would transform the most difficult students too. Raising voice to get students’ attention is a negative approach creating stress and similar vibes in the class. It is also imperative that one is punctual and regular; go the extra mile when you can.
