Investigating the Impact of Different Teaching Methods in College Chinese Courses on Cognitive Understanding and Brain Activation Patterns Using Portable fNIRS.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to investigate how different instructional methods in college Chinese language education-traditional lecture (TL), group discussion (GD), and flipped classroom (FC)-affect students' cognitive comprehension and prefrontal cortical activation. A key focus was to demonstrate the feasibility and value of using portable functional near-infrared spectroscopy (fNIRS) sensors to capture real-time brain activity in ecologically valid classroom settings.
methodsA total of 30 undergraduate students were randomly assigned to one of three instructional conditions. Participants completed comprehension assessments, a semantic conflict task, and NASA-TLX workload ratings. Simultaneously, a wearable fNIRS sensor system was used to monitor hemodynamic responses (ΔHbO) and functional connectivity in prefrontal cortical areas, enabling noninvasive neural measurements during naturalistic learning.
resultsThe FC condition showed significantly higher total comprehension scores compared to the GD (p = 0.002) and TL conditions (p < 0.001), with the greatest advantage observed in higher-order semantic processing (p < 0.001). The GD condition outperformed others in resolving semantic conflict, showing the lowest interference cost and highest accuracy in the modern-meaning interference cost. The FC condition reported the lowest overall cognitive workload (56.7 ± 6.2), significantly lower than GD and TL (p < 0.001). fNIRS sensor data revealed the highest ΔHbO activation in the FC condition, particularly in the left DLPFC, along with stronger functional connectivity between L-DLPFC and L-VLPFC. Brain-behavior correlations showed a positive association between L-DLPFC activation and comprehension score (r = 0.51, p < 0.001), and a negative association between connectivity strength and semantic interference cost (r = -0.57, p = 0.001).
conclusionThe integration of portable fNIRS sensors into educational research provides valuable insights into how instructional strategies modulate both cognition and brain function in real-world classroom environments. The flipped classroom method proves most effective in enhancing semantic comprehension, lowering cognitive demands, and promoting prefrontal engagement. These findings validate the application of wearable brain-sensing technologies to evaluate and optimize pedagogical practices in higher education.
