The application and effect assessment of biomechanics in English writing instruction
Abstract
This study aims to investigate the application and effectiveness assessment of biomechanical principles in English writing instruction. The research selected 200 students from a key secondary school as subjects, who were divided into experimental and control groups of 100 students each using stratified random sampling. The intervention period lasted 8 weeks, followed by a 4-week follow-up. A multidimensional evaluation system was established, incorporating biomechanical parameters (35%), learning outcomes (40%), and comfort levels (25%). Data collection and analysis were conducted using OptiTrack motion capture systems, surface electromyography, and pressure sensor array systems. Results indicated that the experimental group’s overall writing quality scores improved from 72.3 ± 4.5 to 90.6 ± 3.8, with an improvement rate (25.3%) significantly higher than the control group (9.3%). The incidence of poor posture decreased from 45.6% to 12.3%, while the duration of standard posture maintenance increased from an average of 25 min to 42 min. Regarding age differences, the junior high school group demonstrated better postural adaptability (improvement rate 42.5 ± 4.2%), while the senior high school group showed superior writing stability (coefficient of variation 12.3 ± 1.5%). The study confirms the positive role of biomechanics in English writing instruction, providing scientific evidence and practical references for improving English writing pedagogy. Additionally, the developed evaluation system offers new methodological support for related research.
