Learning of fraction is distributed from first grade to sixth grade, the significance of which is very important. According to past research, part of seniors cannot get the point of fractions. In order to help students fully understand the notion of fractions, teachers should take students’ learning difficulties into account and make up their deficiencies. Formative assessment is an effective method which help teacher to know students’ learning situation, but which is hard to apply in real teaching situation. This research combine mobile device and wireless network environment and implement an on-line formative assessment system according Ordering Theory. When the tolerance is 0.12 and the samples were within 500, the efficiency of the like denominators subtraction unit hierarchy can achieved 80%, and the accuracy can achieved 87%. This study used Chi-Square Test (Independence of Test) and two-way mixed design ANOVA to analyze data. The results showed that the effects of using on-line formative assessment to help teaching and conventional paper-and-pencil-based testing to help teaching, the learning effect of the students on like denominators subtraction unit has no significant difference. en_US dc.description.sponsorship 資訊教育研究所 zh_TW dc.identifier GN0694080080 dc.identifier.uri http://etds.lib.ntnu.edu.tw/cgi-bin/gs32/gsweb.cgi?o=dstdcdr&s=id=%22GN0694080080%22.&%22.id.& dc.identifier.uri http://rportal.lib.ntnu.edu.tw:80/handle/20.500.12235/92940 dc.language 中文 dc.subject 同分母減法 zh_TW dc.subject 順序理論 zh_TW dc.subject 形成性評量 zh_TW dc.subject 行動載具 zh_TW dc.subject like denominators subtraction en_US dc.subject ordering theory en_US dc.subject formative assessment en_US dc.subject mobile device en_US dc.title 整合行動載具之線上形成性評量對國小同分母分數減法單元之成效 zh_TW dc.title The Effect of Mobile-Device Based On-Line Formative Assessment On Like Denominators Subtraction Unit en_US
