  Social computing is the study of how technology shapes human social
interactions. This topic has become increasingly relevant to secondary school
students (ages 11--18) as more of young people's everyday social experiences
take place online, particularly with the continuing effects of the COVID-19
pandemic. However, social computing topics are rarely touched upon in existing
middle and high school curricula. We seek to introduce concepts from social
computing to secondary school students so they can understand how computing has
wide-ranging social implications that touch upon their everyday lives, as well
as think critically about both the positive and negative sides of different
social technology designs.
  In this report, we present a series of six lessons combining presentations
and hands-on activities covering topics within social computing and detail our
experience teaching these lessons to approximately 1,405 students across 13
middle and high schools in our local school district. We developed lessons
covering how social computing relates to the topics of Data Management,
Encrypted Messaging, Human-Computer Interaction Careers, Machine Learning and
Bias, Misinformation, and Online Behavior. We found that 81.13% of students
expressed greater interest in the content of our lessons compared to their
interest in STEM overall. We also found from pre- and post-lesson comprehension
questions that 63.65% learned new concepts from the main activity. We release
all lesson materials on a website for public use. From our experience, we
observed that students were engaged in these topics and found enjoyment in
finding connections between computing and their own lives.
