Make sure all of your students unde

Make sure all of your students understand what you are teaching. If you ask your class, they may say yes but you may not hear the little voice that says no.
It bears mentioning again that, making your lesson plans, the most important element is the objective. The other parts of the lesson (part for "lecture teaching", part for students working, and part for quiet working) spring from or arise from that objective.
You should be at least 1-2 weeks ahead in terms of your lesson plans.
Add a little love to every activity you teach. You will get better results from your students.
Effective classroom management is among the most important skills to have as a teacher.
Your evaluation (i.e. tests and quizzes) should be formed based on the original objective. It should evaluate how well the students met the objectives you set out when planning your lessons.
It is never too late to start to implement these tips and ideas.
It is important to use questioning techniques throughout to check that the learner has understood. If the learner finds it to easy to answer then probe them further to gain a more detailed response. Using the terms 'why' and 'how'. This will stretch learners further.
It is important to have some distance from your students, particularly for the first 2 weeks of the term. If you cannot keep a professional distance from your students, it is because YOU have the need to relate to them on a more personal level, probably because you're lacking that somewhere in your more personal life. It is your responsibility to recognize this and deal with it.
