47Understanding how students learn is crucial for helping them succeed. We examined brain function in 48 107 undergraduate students during a task known to be challenging for many students -physics problem 49 solving -to characterize underlying neural mechanisms and determine how these support 50 comprehension and proficiency. Further, we applied module analysis to response distributions, defining 51 groups of students who answered using similar physics conceptions, and probed for brain differences 52 linked with different conceptual approaches. We found integrated executive, attentional, visual motion, 53 and default mode brain systems cooperate to achieve sequential and sustained physics-related 54 cognition. While accuracy alone did not predict brain function, dissociable brain patterns were observed 55 when students solved problems using different physics conceptions, and increased success was linked to 56 conceptual coherence. Our analyses demonstrate that episodic associations and control processes 57 operate in tandem to support physics reasoning, offering potential insight to support student learning. 58 59 60 61
