In my experience, study groups are very effective because they allow students to mingle and discuss the work they've been given with their peers. This allows all of the students to round out their learning styles as they work together.
Tactile exercises are important because they allow the students to be both comfortable and proficient at using the instruments they'll use daily as a hygienist. After gaining all of knowledge they'll need, correct and effective usage of the instruments is the second most aspect of the job.
