Helping Learners Master Course Topics: Instructor's Best Action | TK0-201 Exam | CompTIA CTT+

C.

The best action for the instructor to take when dealing with a mix of learners who are either familiar or unfamiliar with the course topics is to use a combination of teaching strategies that cater to different learning needs. Option A suggests that the experienced learners should do independent labs while the instructor focuses on teaching the learners having difficulty. This approach is not ideal as it leaves out the experienced learners and may create an environment where the struggling learners feel singled out.

Option B suggests the use of diagrams to clarify the material. While this may be a helpful teaching strategy, it is unlikely to address the varying levels of familiarity with the course topics among the learners.

Option C suggests that the instructor should encourage learners who have experience with the course to share and discuss it with the class. This approach has the potential to create a collaborative learning environment where experienced learners can share their knowledge with those who are having difficulty with the course topics. However, it is important to ensure that the discussions are structured and guided to ensure that they are on-topic and relevant to the course.

Option D suggests that the instructor should teach expanded objectives to challenge the experienced learners. This approach may be beneficial in engaging the experienced learners, but it does not address the needs of the struggling learners. Moreover, it may lead to a situation where the experienced learners become disengaged from the course as they feel that they are not learning anything new.

Therefore, the best action for the instructor to take is to use a combination of teaching strategies that cater to different learning needs. The instructor should consider incorporating visual aids, hands-on activities, group discussions, and other strategies that are known to be effective in catering to different learning styles. Additionally, the instructor should consider providing extra support to the struggling learners, such as one-on-one tutoring, additional resources, or alternative assignments. Overall, the goal should be to create an inclusive learning environment where all learners can feel engaged and supported.
