Tutoring is a facilitative process that requires the active participation of both the tutor and the learner. Tutors aim to identify the gaps in knowledge, while simultaneously facilitating learning through lots of practice, revision of the theory, and interactive discussion of the subject matter. A tutor is an excellent solution to large classroom sizes, different learning styles, static curricula, and learners needing more individual attention. A one-on-one tutor can assess where a learner needs reinforcement of specific material, and use personalized teaching methods to fill in these gaps in knowledge effectively.
