Photos show how classrooms have changed for millennials, Gen Z, and Gen Alpha

• US classrooms have changed dramatically since the early 2000s.
• They’ve changed through technology, mainly from computers and tablets to social media and AI.
• Photos show how Millennials, Gen Z, and Gen Alpha all grew up in vastly different classrooms.

COVID-19 disrupted how students and teachers interacted in classrooms in the early 2020s.

When schools closed in 2020, classes suddenly moved onto laptops and video calls.

Teachers had to find new ways to teach lessons and keep students engaged remotely, while students navigated a school experience marked by muted microphones, virtual assignments, and far less face-to-face time.

Mask requirements made it difficult for students and teachers to listen to each other and understand social cues. Physical-distancing rules, which often called for students to stay 6 feet apart early in the pandemic, also made socializing harder.

The change in learning led to a mass loss of attention in students, socialization issues, and a chronic absenteeism rate that spiked following the pandemic.

School entrances saw heightened security measures as safety became a greater concern.

The mid-2010s saw a dramatic rise in school shootings — 522 victims were killed in school shootings between 2015 and 2025, compared to 195 victims between 2005 and 2015.

In 2024, then-President Joe Biden said more than 400 school shootings had occurred since Columbine, exposing more than 370,000 students to gun violence.

As such, schools across the US responded with locked entrances, visitor check-ins, cameras, and metal detectors.

According to data from the National Center for Education Statistics, 61% of US public schools used security cameras to monitor schools in the 2009-2010 school year. That percentage rose to 92.6% in the 2021-2022 school year.

In 2026, classrooms have adopted AI tools to personalize learning lessons for each student.

AI is beginning to reshape the classroom much like computers and the internet did in earlier decades.

According to an October 2025 College Board report, 69% of high school students reported using ChatGPT to help with schoolwork in May 2025.

Teachers can use AI-powered tools to create practice materials, provide quicker feedback, and tailor lessons to students’ different needs — while schools continue to figure out where and if AI fits best in the classroom.
