The “Social Contagion” Theory of Good and Bad Grades

The “Social Contagion” Theory of Good and Bad Grades

Does who you hang out with in school affect your grades? wondered a group of high-school students. In partnership with the National Science Foundation, they conducted a two-year study of 160 juniors in an Endwell (NY) high school and found that students’ grades gravitate toward the average of the social circle in which they move. In other words, if a student hangs out with friends whose average GPA is higher, that student’s GPA is likely to improve. And if a student hangs with friends whose GPA is lower, his or her GPA tends to drop.

Mentors.net - a Professional Development Resource

Mentors.net was founded in 1995 as a professional development resource for school administrators leading new teacher induction programs. It soon evolved into a destination where both new and student teachers could reflect on their teaching experiences. Now, nearly thirty years later, Mentors.net has taken on a new direction—serving as a platform for beginning teachers, preservice educators, and

other professionals to share their insights and experiences from the early years of teaching, with a focus on integrating artificial intelligence. We invite you to contribute by sharing your experiences in the form of a journal article, story, reflection, or timely tips, especially on how you incorporate AI into your teaching

practice. Submissions may range from a 500-word personal reflection to a 2,000-word article with formal citations.
