To what extent do you agree? "There will always be a number of demotivated low achievers no matter how we differentiate our methods of teaching."

Check out this research study on the following link, it has good answers:

I do agree with your statement. Anyhow this is the truth how people are, and how life moves!

The method  of teaching is very simple , while we try to teach our children all about life , our children teach us what life is all about

Everyone has a 'button' to press that gets them motivated and interested. That is the whole point of teaching - you have to find it. If it wasn't everyone would be able to do it. I always say to my staff  - 'teaching people who want to learn is easy and not really teaching. Teaching those that don't want to learn - now that's teaching.'

Many and varied teaching methods, but more importantly how to employ properly supports active learning strategies different/either differentiate methods of teaching depends on the teacher, choose the appropriate method of art not master him each one there is no chance for frustration since you always see the most up-to-date teaching methods accept my greetings and appreciation

In simpler terms, no matter how hard you try, there'll always be bad students. Agree

turning into an everyone's talk, demotivation in the teaching forum has been considered as a gloomy concept.in fact the well use of  satisfied methodology by teachers strenghthens the student's circumstances as inadequate school facilities,lack of intrinsic motivation...so teacher competence and teaching style could be apart and not partial the key to better achievements .Equally important ,demotivated low achivers may be lack enthusiasm in teaching or may be have low salaries that discourage them .

I agree that there will always be students that are not motivated. I use role playing. It helps to motivate the student. Have the student role play the part of teacher. For example: have the student read to the class a reading assignment. or have the student explain a math problem to the class. It is a way to involve them in class activities and also helps motivate them.

 It is not about the method it is about the result at the end 

Sad, but true, and I agree with the statement. But, let me add that I also fully support Nick Sherriff's view that it is the duty of us teachers to help every student realize his/her full potential. Lack of motivation has its own reasons (and sometimes they lie in the system too, and the poor teacher finds it hard to fight the system alone) and the real teaching lies in sensing those reasons and helping the unmotivated move out of their influence. I know I sound too idealistic here, but in a majority of cases this works. Methods of teaching do not have much to do with motivation; it is teacher's own charisma that works.
