Effect of Brain-Based Learning on Students' Academic Achievement in Mathematics at Secondary Level: A Quasi-Experimental Investigation Across Stratified Ability Tiers

Abstract

The study highlights the difference between traditional instructional pedagogies and neuro-compatible teaching frameworks at secondary education in the subject of mathematics. The study evaluated the comparative effectiveness of brain-based learning (BBL) versus conventional teacher-centered lectures on the academic achievement of secondary school students in mathematics across high, average, and low achievement strata. A quantitative quasi-experimental pre-test/post-test non-equivalent control group design was implemented with 60 Grade 9 students (n = 30 experimental, n = 30 control) in public secondary schools of Sialkot district, Pakistan. Participants were stratified into high (n = 10), average (n = 10), and low (n = 10) achievement sub-groups based on prior annual examination scores. The experimental cohort underwent an 8-week intervention integrating Caine and Caine's 12 principles (relaxed alertness, orchestrated immersion, active processing) across factorization and trigonometry units, while the control cohort received conventional lecture-based instruction. Outcome data were gathered via a validated 75-mark Teacher-Made Achievement Test (TMAT). Baseline evaluations confirmed statistical equivalence between cohorts (p = .562). Post-test analysis demonstrated significant overall superiority for the BBL group (M = 47.07, SD = 14.55) over the control group (M = 36.60, SD = 8.54; t = 3.398, p = .001). Achievement gain scores for the BBL group (M = 18.00, SD = 7.39) were nearly triple those of the control group (M = 6.40, SD = 2.33; t = 8.200, p < .001). Stratified analyses revealed significant gain advantages for high achievers (M_gain = 23.60 vs. 8.90, p < .001), average achievers (M_gain = 21.40 vs. 6.00, p < .001), and low achievers (M_gain = 9.00 vs. 4.30, p < .001). Re-engineering secondary mathematics classrooms from threat-induced drills to pattern-rich, emotionally safe learning ecosystems optimizes executive cognitive processing and reduces mathematics anxiety. Teachers must transition into 'neural architects' to cultivate sustainable conceptual mastery.
