There are a good many ideas out there about what it takes to be a good English teacher and I’d like to share some of them here.
How can anyone just point out the important factors in teaching English in just a few hundred words?
I’m not sure if this can be done as I intended it to be but I will try.
Student-centered learning is key. Many T’s are all about the TTT (teacher talking time) which should be reduced. Aim for 20%.
I+1  is also an incredibly important factor. We need to make sure all our lessons are pitched at this level.
Students work better when their affective filters are reduced. This is something teachers need to be concerned with.
Teachers also need to be sure they are empowering students. Students work better and learn more when they are empowered.
Of course, just doing the above is not enough. Lessons need to be planned appropriately. Proper scaffolding at each stage!
The stages of the lesson need to follow the correct frameworks and have the interaction appropriately planned for each section.
All the above is important but doesn’t really mean anything if we are not eliciting creativity from students, which we should do.
Let’s be clear, in the 21st century it is the responsibility of teachers of all subjects to foster creativity in all students.
But we need to be sure to consider students’ different learning styles and multiple intelligences or it will all be for naught.
Unless we create lessons that match the unique needs of all our learners we will be wasting our time and theirs.
Learners are all different. Our lessons need to match their styles and intelligences plus wants and needs and moods and more.
Learner’s needs must be considered and we must also ensure that we are developing their critical thinking skills. This is a must.
Students need to be given tools to succeed in the modern era. We should remember most of our students are digital natives.
However we do it, as teachers we need to be sure that we do and remember everything listed above and make them a priority.
I hope and believe I have offered some useful ideas and starting points here. 
Though, if all the above fails you can just flip the classroom or employ gamification.
