We аre becоming increаsingly wоrried аbоut kids’ socialization skills after the pandemic. We are working with a group of kids (ages 7-10). We assign one group of kids to the socialization group where they play board games, playground games, and participate in interactive group activities. Another group of kids (ages 7 -10) reads silently or plays independent video games. We believe those in the socialization group will gain more friends and learn better social skills. We want to determine if this program should be rolled out in other schools or nationwide. Please discuss and define who would be in the comparison and intervention group? Make sure to utilize the scenario in the question in your answer. Please describe why we need to have both groups for this intervention. Which one do you think is most crucial? Why?
