This study examined the reliability and validity of judging system scores of past hip-hop dance competitions in Japan. The analysis focused on the scores for each assessment category separately. Judges' scores were obtained from national dance competitions held annually in Japan between 2014 and 2019. In these competitions, five experienced judges evaluated the dancers' performances. The judges scored on a 10-point scale in five categories as follows: creativity, expression and interpretation, impression, technical quality, and synchronisation. This study found that the technical quality category demonstrated good reliability, whilst the impression showed poor reliability. Systematic bias was significant for all categories. There are no levels of difficulty defined for technique, no criteria set for correct movement and no explanation provided for each scoring level, which suggests that each judge may have interpreted the criteria for evaluating hip-hop dance differently. Developing these definitions and identifying the biases that affect evaluation would ensure a reliable evaluation system.
本研究考察了日本过去嘻哈舞蹈比赛评判系统分数的可靠性和有效性。分析分别聚焦于每个评估类别的分数。评判分数来自2014年至2019年在日本每年举办的全国舞蹈比赛。在这些比赛中，五名经验丰富的评委对舞者的表现进行评估。评委们在五个类别中以10分制打分，具体如下：创造力、表现力与诠释、印象、技术质量和同步性。本研究发现，技术质量类别显示出良好的可靠性，而印象类别显示出较差的可靠性。所有类别均存在显著的系统偏差。对于技术没有定义难度级别，没有为正确动作设定标准，也没有对每个评分级别进行解释，这表明每位评委可能对嘻哈舞蹈的评估标准有不同的理解。制定这些定义并识别影响评估的偏差将确保建立一个可靠的评估系统。
