"It seems that such efforts have, for the most part, struggled to effect much change in the educational world. The way in which certain instructional trends—education buzzwords like “collaborative learning” and “project-based learning” and “flipped classrooms”—are applied often neglect the needs of introverts. In fact, these trends could mean that classroom environments that embrace extroverted behavior—through dynamic and social learning activities—are being promoted now more than ever. These can be appealing qualities in the classroom, of course, but overemphasizing them can undermine the learning of students who are inward-thinking and easily drained by constant interactions with others."
