Screens in the Classroom: What Every Parent Should Know

Technology has become a central part of modern education, and in many schools, students now spend a significant portion of their day in front of screens. While digital devices are often promoted as tools that improve learning and prepare children for the future, a growing body of research suggests that excessive reliance on technology in the classroom may come with unexpected costs.

Experts warn that prolonged screen use can affect not only academic performance, but also physical health, concentration, and overall well being.

The Growing Presence of Screens in Schools

A nationwide survey conducted by the National Center for Education Statistics found that nearly 90 percent of public schools in the United States now provide a personal digital device for every student.

As technology becomes increasingly integrated into classrooms, many parents and educators have begun asking an important question: Is more technology always better for learning?

According to brain researcher Jared Cooney Horvath, the answer may not be as straightforward as many assume.

What Research Reveals About Digital Learning

In his book, The Digital Illusion: How Technology in Classrooms Is Hurting Our Children’s Learning, Horvath presents evidence suggesting that students who rely more heavily on computers often achieve lower academic outcomes.

These findings are reflected in numerous international studies and standardized assessments that examine student performance around the world.

Research has repeatedly shown that students tend to understand and retain information more effectively when reading printed materials rather than digital text. Similarly, students often learn more when they write notes and summaries by hand instead of typing them on a keyboard.

Writing by hand appears to encourage deeper processing of information, helping students better organize and remember what they learn.

The Impact on Focus and Concentration

Beyond academics, experts are increasingly concerned about the effect of screens on children's ability to focus.

Many digital platforms, videos, and games are specifically designed to capture and hold attention for as long as possible. While this can make screens highly engaging, it may also make it more difficult for children to develop the patience and concentration required for deeper learning.

Reading a book, conducting research, solving problems, and engaging in sustained thought require a different kind of attention, one that is not fueled by constant stimulation and rapid rewards.

Physical Effects of Excessive Screen Time

The effects of prolonged screen use extend beyond the classroom.

Staring at screens for long periods is a sedentary activity, while the human body is designed for movement, exploration, and sensory engagement. Researchers have also linked increased screen time to a higher risk of developing nearsightedness in children and teenagers.

Children learn best when they are actively involved in the learning process, whether through movement, hands on experiences, discussion, or interaction with the world around them.

Finding the Right Balance

Technology undoubtedly offers valuable educational tools, but many researchers believe it works best when used in moderation rather than as a replacement for traditional learning methods.

As schools continue to embrace digital education, the challenge will be finding a balance that allows students to benefit from technology without sacrificing the proven advantages of reading, writing, movement, and face to face interaction.
