From Fragmented Attention to Cognitive Endurance: A Perspective for Secondary Science Classrooms

Abstract

Secondary science learning requires students to interpret evidence, connect representations, and develop explanations while managing digital tools and frequent transitions. Drawing on cognitive research and classroom observations, this perspective examines how task switching and competing demands can interrupt the continuity of scientific reasoning. It defines cognitive endurance as students’ developing capacity to remain engaged with demanding ideas long enough to construct understanding. The article uses cognitive malnourishment as a classroom metaphor for environments that provide constant stimulation but limited time for reflection, integration, and sustained conceptual work. It recommends protecting focused work periods, simplifying digital pathways, building processing pauses into lessons, pacing instruction according to the thinking required, and preserving accessibility supports for learner variability. The article argues that attention is not only a behavioral expectation but also a limited learning resource shaped by instructional design and broader school structures.
