How has digital technologies impacted children's focus in the classroom

- Attention fragmentation: Frequent switches between apps, notifications, and multimedia promote task-switching and reduce sustained attention spans (Rosen et al., 2013; Carr, 2010). - Increased distractibility: Personal devices and in-class digital content can introduce off-task browsing, social media use, and multitasking, lowering on-task time and learning efficiency (Kraushaar & Novak, 2010; Kuznekoff & Titsworth, 2013). - Cognitive load and shallow processing: Rich multimedia and rapid information flow can raise intrinsic/extraneous cognitive load, encouraging surface learning rather than deep, reflective processing (Sweller, 1994; Mayer, 2005). - Positive engagement and individualized focus: When well-designed and integrated (adaptive software, interactive simulations, gamified learning), technology can boost motivation, support differentiated pacing, and improve sustained engagement for some learners (Hattie, 2009; OECD, 2015). - Mixed effects by context and age: Impacts depend on device policies, teacher training, instructional design, and student self-regulation; younger children and those with weaker executive control are more vulnerable to distraction (Radesky et al., 2015). - Practical implications: Clear device-use policies, teacher-led integration, training in digital self-regulation, and design that reduces extraneous stimuli can mitigate harms and harness benefits.
