The more popular system of teaching in the development of schools in ancient India was "word of mouth".

In the development of schools in ancient India, the system of teaching "by word of mouth" was quite common. This system of teaching took the form of oral transmission, in which the teacher imparted knowledge to the students through the spoken word. Students were required to listen to and memorize what the teacher said, and then to consolidate what they had learned by reciting and writing it down.

In ancient India, the main purpose of education was to produce good citizens and devout religious followers. As a result, instruction often included religious classics, moral codes, cultural traditions, and a variety of practical skills. Teachers usually chose appropriate content for their students based on their diverse backgrounds and learning abilities.

The system of teaching by word of mouth has a long history in ancient India. As early as the Vedic era (c. 1500 BCE - 500 BCE), specialized groups of teachers and students were already present in ancient India. These teachers were called Brahmans and were responsible for imparting both religious and secular knowledge. The students, on the other hand, came from different social classes, including nobles, merchants, craftsmen and peasants.

In schools in ancient India, teachers usually used a variety of methods to teach their students. In addition to simple verbal explanations, they would use diagrams, images, and physical displays to help students better understand what they were teaching. In addition, teachers test their theories through observation and experimentation to ensure the quality of their teaching.

There were some problems with the ancient Indian system of teaching by word of mouth

Because the content of teaching depended on the teacher's verbal explanations, it was difficult for students to independently verify and reflect on what they had learned. In addition, due to the lack of a systematic evaluation system, it is difficult for teachers to understand students' learning progress and mastery.

Despite this, the system of teaching by word of mouth still dominated ancient Indian schools. This system of teaching made an important contribution to the transmission and development of ancient Indian culture and laid the foundation for the later Indian education system.

In addition to the "oral" teaching system, there were other forms of educational institutions in ancient India, such as "Gurukula" and "Vidya Mandala" (Vidya Mandala). "(Gurukula) and Vidya Mandir. These institutions were usually funded by temples or the nobility and provided students with a more systematic and comprehensive education. In these institutions, students learn not only the religious classics and ethics, but also various practical skills and cultural knowledge.
