E-learning app Usability test (Subjective study)

The subjective test When the satisfaction questionnaire was used, participants were asked to rate the 64 items related to the interface design of educational apps with a 5-point Likert scale that range from 1 for Not at all true,2 for Not very true,3 for Somewhat True, 4 for True to 5 For Very True. And In accordance with the SUMI measuring criteria, each point weighs Zero for not true at all, 1 point for Not very true, 2 points for somewhat true, 3 points for True and 4 points for Very true. The questionnaire design ensured that the research findings thereof were converted from the subjective qualitative nature to quantitative data through coding using a five-point Likert scale and then analyzed using statistical package for social scientists (SPSS)主观测试环节：本次研究采用满意度问卷开展主观测试，要求参与者以5点李克特量表（5-point Likert scale）对64项教育应用界面设计相关条目进行评分。该量表的标注评分区间为1至5分，其中1分对应"完全不符合"，2分对应"不太符合"，3分对应"部分符合"，4分对应"符合"，5分对应"非常符合"。此外，依据SUMI测量标准，各评分对应的分值权重为：完全不符合计0分，不太符合计1分，部分符合计2分，符合计3分，非常符合计4分。本问卷的设计确保其研究结果可通过5点李克特量表编码，从主观质性内容转化为量化数据，随后采用社会科学统计分析软件（SPSS）完成数据分析。
