Nowadays we could see a low standard in the students, this is because the teachers donot take much care about the overall development of a student. Its a sacrificial and a profession which needs continuous assessment and training more than teaching. Thus I agree with the question
If we examine carefully what must be the teachers' main goal we will soon realize the importance of this question. A teacher must be a long life learner in order to find the ways to positively attribute to his/hers students' maximum progress and welfare. If the acquirement of qualification and expertise do not facilitate effective teaching and rather keeps teachers attention away from his/hers students progress and welfare this is not right.
A teacher is expected to make sacrifice in terms of personal benefits. The student progress and welfare should be the major priority of a teacher. The teachers' actions and in-actions must be channeled towards achieving this objective.
