The applicant articulated the challenge of teaching a group ski class as opposed to teaching a private lesson. In the latter, she noted, her main objective was to discover where the student was in terms of skill and understanding, and then move that student forward to the next level. The group class, on the other hand, presented the interesting challenge of diversity in skills, abilities and learning styles. Whereas the individual student can easily be accommodated in the one:one setting, the large group forces the teacher to become creative in her use of instructional strategies.
In the same way, a Flight Instructor quickly and easily meets the needs of her individual students, whereas a Ground School Teacher must assess the divergent needs of a group of learners, and differentiate her approach to the topic(s) accordingly.
No easy challenge, this teaching thing!
