How do you feel about a skills-based vs a factual approach to teaching management?

Theoretical teaching is not a realistic teaching work but rely on the skills acquired by the teacher, who work through self-development

Skills trainings brings productivity rather than theoretical training.

[Suppose you are Painting Artist: You can teach you skills only to those who are interested in the similar field of art, paintings and drawings to make them aware of it and enhance the learners skill.

But if you are teacher of Mathematics, you can impart the knowledge in almost all as they are required for the human life. The learners acquire the knowledge as per their requirements and need of the hour with interest and participation.]
