Should teacher be paid according to how much their students learn

Should teacher be paid according to how much their students
learn?
Teaching quality is the key element to influence learners`
achievements. Being a teacher myself, I am not completely satisfied
with the teachers` performance in my country.
Thus, I find the idea of financial interdependence between teaching
quality and students` academic results appealing. I believe, I can
solve such common problems as wasted time or boring lessons.
Teaching is a paid job, therefore, if some money incentives were
introduced, it would encourage teachers to seek for the most
effective way to present and get across the material. For example, it
could make us more interested in new teaching methods. We would
attend special workshops more often and do our best to implement
the techniques we previously shied away from.
If some objective tests of students ` achievements were introduced,
teachers would be more interested in getting involved all the class.
Which could help to solve the problem of teachers focusing their
attention on the strong students only, while neglecting less
advanced ones.
Making the learners achievement the crucial element for estimating
the quality of the lesson would encourage the teachers be more
efficient with their time. It could eliminate the common problem of
wasted time and personal stories. Shifting the emphasis from
?optimistic environment in class ?to academic achievements would
be more beneficial to the students in the long run.
I believe, that financial incentives are able to improve teachers
performance in class,
make us more interested in using some innovative techniques, be more
productive with the time and focused on all the students. That is why I
favor the idea of changing the pay system for teachers and make it
more competitive.
