Ask any educator the best way to teach someone and their first response will be everyone learns differently. It's the greatest challenge yet where the most creative methods are born.
Have you been given a new hire who needs onboarding? Do you want to help teach your co-workers the skills you learned at a camp or DrupalCon? Do you want to help empower your clients to confidently navigate their own site or product? No matter the purpose of teaching, for best results you must determine your student’s style and adapt to their learning needs.
