    本研究旨在利用卷积神经网络(CNN)模型和深度学习方法对高校体育舞蹈教学质量进行综合分析和评价。研究引入了基于一维CNN的教学质量评价(TQE)模型,解决传统评估方法中的主观性和评估标准不一致等问题。通过构建包含24个评价指标的全面TQE体系,本研究创新性地应用深度学习技术对体育舞蹈教育质量进行定量评估。该TQE模型通过卷积层提取局部特征来处理一维评估数据,通过池化层减少维度,并通过全连接层将特征向量输入分类器,实现教学质量的整体评估。实验结果表明,在TQE模型上经过150次迭代训练和验证,实现了收敛,在训练集和验证集上,均方误差(MSE)降至0.0015和0.0216,分别。相对而言,TQE模型在训练中表现出显著较低的MSE,验证,和测试集与反向传播神经网络相比,伴随着更高的R2值,表明在数据拟合方面具有卓越的准确性和性能。进一步分析鲁棒性,参数灵敏度,多场景适应性,长期学习能力揭示了TQE模型在管理嘈杂数据方面的强大弹性和稳定性,不同的参数配置,不同的教学环境,和扩展的时间序列数据。在实际应用中,在X学院的体育舞蹈课程中实施了TQE模式,以评估教学质量并指导教师的改进策略,显著提高了教学质量和学生满意度。总之,本研究通过多维评估系统和1D-CNN模型的应用,对大学体育舞蹈教育质量进行了综合评估。它介绍了一种新颖有效的评估教学质量的方法,为未来的教育发展提供科学依据和实践指导。
    This study aims to comprehensively analyze and evaluate the quality of college physical dance education using Convolutional Neural Network (CNN) models and deep learning methods. The study introduces a teaching quality evaluation (TQE) model based on one-dimensional CNN, addressing issues such as subjectivity and inconsistent evaluation criteria in traditional assessment methods. By constructing a comprehensive TQE system comprising 24 evaluation indicators, this study innovatively applies deep learning technology to quantitatively assess the quality of physical dance education. This TQE model processes one-dimensional evaluation data by extracting local features through convolutional layers, reducing dimensions via pooling layers, and feeding feature vectors into a classifier through fully connected layers to achieve an overall assessment of teaching quality. Experimental results demonstrate that after 150 iterations of training and validation on the TQE model, convergence is achieved, with mean squared error (MSE) decreasing to 0.0015 and 0.0216 on the training and validation sets, respectively. Comparatively, the TQE model exhibits significantly lower MSE on the training, validation, and test sets compared to the Back-Propagation Neural Network, accompanied by a higher R2 value, indicating superior accuracy and performance in data fitting. Further analysis on robustness, parameter sensitivity, multi-scenario adaptability, and long-term learning capabilities reveals the TQE model\'s strong resilience and stability in managing noisy data, varying parameter configurations, diverse teaching contexts, and extended time-series data. In practical applications, the TQE model is implemented in physical dance courses at X College to evaluate teaching quality and guide improvement strategies for instructors, resulting in notable enhancements in teaching quality and student satisfaction. In conclusion, this study offers a comprehensive evaluation of university physical dance education quality through a multidimensional assessment system and the application of the 1D-CNN model. It introduces a novel and effective approach to assessing teaching quality, providing a scientific foundation and practical guidance for future educational advancements.

    (1)背景:由于听障学生在运动或健身项目等社会交往中存在困难,因此听障学生的身体素质(PF)一直是国际研究热点。体育干预被证明可以提高听力受损学生的健身水平;然而,很少有研究评估Cha-cha(一种舞蹈运动)训练对听力受损学生PF水平的影响。(2)目的:本研究旨在通过12周的Cha-cha舞蹈训练对听障儿童进行干预,评估其对PF相关指标的影响,从而为听障儿童有效参与舞蹈练习提供科学的实验依据。(3)方法:将30名听力障碍学生随机分为两组,两组PF指标无差异。Cha-cha舞蹈训练组(CTG,n=15)每周定期参加五次90分钟的Cha-cha舞蹈课,干预总共持续了12周,而对照组(CONG,n=15)过着正常的生活(包括学校体育课)。干预前后测定PF相关指标,并进行了双向重复测量方差分析。(4)结果:经过培训,站立跳远(CONG:1.556±0.256vs.CTG:1.784±0.328,p=0.0136,ES=0.8081),坐达(CONG:21.467±4.539vs.CTG:25.416±5.048,p=0.0328,ES=0.8528),仰卧起坐(CONG:13.867±4.912vs.CTG:27.867±6.833,p<0.0001,ES=2.4677)和跳绳(CONG:52.467±29.691vs.CTG:68.600±21.320,p=0.0067,ES=0.6547)评分有显著性差异。(5)结论:听障学生经过12周的Cha-cha舞蹈训练,听力受损学生下半身力量的PF水平,灵活性,核心强度,心肺耐力得到有效改善;然而,身体形态没有明显变化,上身强度,肺活量,和速度能力。
    (1) Background: The physical fitness (PF) of hearing-impaired students has always been an international research hotspot since hearing-impaired students have difficulty in social interactions such as exercise or fitness programs. Sports interventions are proven to improve the fitness levels of hearing-impaired students; however, few studies evaluating the influence of Cha-cha (a type of Dance sport) training on the PF levels of hearing-impaired students have been conducted. (2) Purpose: This study aimed to intervene in hearing-impaired children through 12 weeks of Cha-cha dance training, evaluating its effects on their PF-related indicators, thus providing a scientific experimental basis for hearing-impaired children to participate in dance exercises effectively. (3) Methods: Thirty students with hearing impairment were randomly divided into two groups, and there was no difference in PF indicators between the two groups. The Cha-cha dance training group (CTG, n = 15) regularly participated in 90-min Cha-cha dance classes five times a week and the intervention lasted a total of 12 weeks, while the control group (CONG, n = 15) lived a normal life (including school physical education classes). Related indicators of PF were measured before and after the intervention, and a two-way repeated-measures analysis of variance was performed. (4) Results: After training, the standing long jump (CONG: 1.556 ± 0.256 vs. CTG: 1.784 ± 0.328, p = 0.0136, ES = 0.8081), sit-and-reach (CONG: 21.467 ± 4.539 vs. CTG: 25.416 ± 5.048, p = 0.0328, ES = 0.8528), sit-ups (CONG: 13.867 ± 4.912 vs. CTG: 27.867 ± 6.833, p < 0.0001, ES = 2.4677) and jump rope (CONG: 52.467 ± 29.691 vs. CTG: 68.600 ± 21.320, p = 0.0067, ES = 0.6547) scores showed significant differences. (5) Conclusions: After 12 weeks of Cha-cha dance training for hearing-impaired students, the PF level of hearing-impaired students in lower-body strength, flexibility, core strength, and cardiorespiratory endurance were effectively improved; however, there was no significant change in body shape, upper-body strength, vital capacity, and speed ability.
