碩士 === 國立臺北教育大學 === 數學暨資訊教育學系(含數學教育碩士班) === 98 === This research analyzes and compares multiplication of fractions on the National-Edition Mathematics Textbooks, as well as discusses the material range, content sequence and authenticity. Versions of 51（1962）, 57（1968）, 64（1975）, 78（1989）and 82（1993）were analyzed using Content Analysis. Results were shown in a chart developed by the researcher. Data are analyzed and results are as follow: 1. On the content: The version of year 82（1993）is slightly different from other years, the rest are similar. The relationship between multiplicand, multiplier and odd number is collected in some of the versions. The proportion of meaning and algorithm differs from each version. 2. On the layout: Each version is different from each other, however all of the versions introduce the definition of multiplication of fractions before operations. 3. On authenticity: Most questions were “real situation” in each version except the version of 82(1993). There were more “authentic situation” than “real situation”. Finally, implications of the findings of this study were discussed, and recommendations were made to textbook editors and teachers.
