Screen Time

A decade-long study designed to prove screens damage children's brains found the opposite instead, challenging one of parenting's most cherished anxieties.

Purpose: Investigate the associations of cumulative exposure to physical activity (PA), sedentary time (ST), and screen time from childhood to adolescence over an 8-year follow-up with cognition in adolescence. Methods: All together, 260 adolescents (136 boys) who were 15–17 y at 8-y follow-up were analyzed. PA and ST were assessed using an Actiheart device, and different types of PA, nonscreen-based ST, and screen time were assessed by a questionnaire at baseline, 2-y and 8-y examinations. Cognition was assessed using CogState tests at 8-year examinations. Results: Self-reported cumulative unsupervised PA from childhood to adolescence was inversely associated with accuracy in working memory task (standardized regression coefficient, β = −0.127; 95% confidence interval [CI], −0.247 to −0.008) in adolescence. Self-reported nonscreen-based ST was inversely associated with reaction time (β = −0.176; 95% CI, −0.299 to −0.053) and accuracy (β = −0.149; 95% CI, −0.274 to −0.024) in working memory tasks. Self-reported screen time was inversely associated with reaction time (β = −0.194; 95% CI, −0.316 to −0.071) and accuracy (β = −0.233; 95% CI, −0.355 to −0.112) in both working memory tasks and directly associated with overall cognition (β = 0.187; 95% CI, 0.070 to 0.305). Conclusion: Accumulating less unsupervised PA and more screen time from childhood to adolescence was associated with better cognition in adolescence.

EdTechWorks supports evidence-based digital learning tools that empower teachers, improve student outcomes and help schools create more effective classrooms.

What the evidence actually says about the EdTech market, technology in classrooms, and those falling test scores ;) The short version I keep hearing three rather confident claims about educational technology, or the broader conversation of technology and education. The EdTech market, and the compani

An evolutionary psychologist is challenging the popular understanding of kids and technology.

For years, the warning has been: smartphones are destroying a generation. But developmental psychologist Candice Odgers says that decades of data on teens tells a different story — violence, alcohol use and pregnancy are at historic lows, and research shows social media may not actually be the culprit for mental health problems. Hear her analysis of what’s really troubling kids these days, and why banning them from online spaces may make things worse.

A four-month program helping K–12 districts build proactive, evidence-based screen time policy.

There’s a groundswell of negative public sentiment towards digital technologies at the moment, and AI is part of it. In this article I’ll look at where GenAI sits in the current techlash, and suggest that the real target of the techlash isn't the technology at all; it's the system that produced it.

Cellphone bans got devices out of students’ hands, according to the first large study. But behavior and academics have not improved, at least so far.

Four states have recently passed legislation to limit teaching and assessments via screens for students. So has the United States' second-largest school district.

Technology must return to its proper place in the classroom — as a supplemental tool rather than the source and summit of education.

Advocating for responsible tech use in schools to reduce screen time, protect student privacy, and promote effective learning methods.

From Salt Lake City to New York City, parents are demanding more sway over the digital tools that schools give children.

"As there was with social media, there is a mountain of data, and it just keeps growing, that these products don't do what they told us they were going to do," Rep. Angela Arsenault, D-Williston, a lead sponsor of the legislation.

2025 Blaschke Report & Toolkit The ubiquity of screens in American K-12 schools has become a pressing and controversial issue in public education. This report examines the different ways screens appear in classrooms and homes. It also examines how educators, families, and policymakers can work together to navigate their inevitable…
