We should study alone or with a teacher? 1. There is no doubt that teachers are the proficient mavens, who are equipped with latest and modern teaching techniques. That is to say, they know the art of delivering difficult concepts in approachable (friendly) ways. Moreover, teachers can provide students with quick solutions of various problems. By this, student can learn effectively in minimal time span. Third, they provide valuable feedback, thereby leading students to achievement of learning success. Thus, it is preferred to have a teacher whenever possible. 2. A systematic approach is essential. Study will become easier if a teacher can tell you the tips of learning particular subjects. For example, in order to fully grasp the skills like swimming and driving, a systematic approach cannot be avoid. Only an experienced tutor can impart such knowledge, on the contrary self-learning will not help in such situation. Moreover, self-learning may end up in dangerous situations if some learning steps go wrong. Thus, it is apparent that teachers are essential in most situations. 3. Mistakes are very common in learning procedure. Teachers can support students by correcting their mistakes and providing feedback whenever they require. On the other hand, a self-learner may not realize when he or she is making a mistake so that they may end up learning it wrongly. For instance, a child learning mathematics without a teacher may end up using a wrong arithmetic formula. Therefore a teacher's assistance in correction and suggestion is imperative.
