It is true that the learning strategy of people has changed nowadays, especially after modern educational technologies have emerged. Today, some people find solo learning more effective, whereas others believe that having a teacher is more beneficial. While both approaches have their advantages, I believe learning with a teacher is generally more beneficial.
First of all, having a tutor gives a learner many benefits. A mentor can help a student in various ways. He provides structured guidance, which enables students to avoid common mistakes and understand difficult concepts more efficiently. For example, a mathematics teacher can immediately explain where a student has gone wrong, saving hours of confusion. Moreover, an instructor may give some useful tips and tricks to do well in exams and also evaluate the learner by taking tests as well. Having a teacher often prevents a student from searching through guidelines on his own to get a proper direction for learning, which reduces his valuable time and effort.
On the other hand, learning without a teacher also has some advantages. When a student learns on his own, without having an instructor, he can gain a valuable skill of individual learning. In particular, with the help of modern technologies and the internet, he can browse through lots of resources available online and acquire the knowledge he needs. Besides, it saves money as well which he would need to pay to the mentor. Furthermore, the learner can solely focus on his learning and achieve his goal more easily.
In conclusion, both strategies have some advantages. Having a teacher makes learning faster and impactful in a proper direction. Though self learning is also effective to some extent. It depends on the student and varies from person to person.
