Limited Participation: Kagan structures typically involve just a few students working together at a time, which limits the number of students who can actively participate in a lesson.

Focused on Some Outcomes: Because Kagan structures are directed toward specific outcomes, other kinds of learning can be disregarded or ignored completely.

Potential for Student Boredom: Since the activities are highly structured, the same activities can become repetitive, resulting in student boredom.

Unique Coaching Needs: Kagan structures require a good amount of coaching from the teacher to ensure students stay on task and understand how to participate in the structure.

Low Engagement: Since the focus of the activity is typically on the group, it can lead to low student engagement overall and in some cases, student apathy.
