The U.S. spent $30 billion to ditch textbooks for laptops and tablets, but the result is a generation less cognitively capable than their parents. This is a stark reminder that technology's impact on learning is complex and multifaceted. While the intention was to empower students with access to more knowledge, the reality is quite different.
The Cognitive Decline of Gen Z
Neuroscientist Jared Cooney Horvath testified before the U.S. Senate Committee on Commerce, Science, and Transportation that Gen Z is the first generation in modern history to score lower on standardized tests than the previous one. This decline in cognitive capability is not just about literacy and numeracy; it's a reflection of a broader trend. Horvath cited Program for International Student Assessment data, showing a correlation between increased screen time and worse test scores.
The introduction of the iPhone in 2007 and the rise of social media and gaming apps have contributed to this issue. These technologies are designed to be addictive, keeping users engaged for extended periods. Jean Twenge, a psychology professor, argues that this ease of access and the addictive nature of these platforms hinder learning, as they disrupt sustained attention and task-switching.
The Role of Technology in the Classroom
A 2021 EdWeek Research Center poll revealed that teachers spend a significant amount of time with educational technology, with 55% reporting one to four hours per day. However, students often use technology for off-task activities, as evidenced by a 2014 study. This tendency to get distracted is a critical factor in the erosion of learning capabilities.
Horvath emphasizes that learning is effortful and challenging, and the friction of these challenges is essential for deep understanding and future transfer of knowledge. Technology, in its current form, often undermines this process.
Solving the Tech Crisis
To address this crisis, Horvath suggests imposing efficacy standards and funding research to identify effective digital tools. Congress could also limit tracking behavior and data collection on minors. Schools are taking action by banning cellphones during instructional time and limiting their use in the classroom.
Ultimately, the responsibility lies in recognizing that the current approach to education technology is a failed experiment. Gen Z is not to blame for being exposed to technology; rather, it's a policy failure. Horvath calls for a reevaluation of educational strategies to ensure that technology enhances learning rather than hinders it.
