National assessments suggest that many students do not display proficiency with fractions. Considering that time and materials are precious resources, many educators are looking to use technology to provide supplemental instruction with low demand on the instructor. The current study utilized a multiple‐baseline design to examine the effects of the Motion Math: Bounce application on the fraction quantity comparison and number line placement skills of three fifth‐grade students. Results indicate that Motion Math: Bounce improved the quantity comparison skills of all three participants and the number line skills of one participant. Additionally, all three participants made improvements from pre‐ to posttest on a measure of general fraction knowledge. Implications for future research and intervention implementation are discussed.

运动数学的影响：反弹对学生的分数知识

全国评估表明，许多学生没有分数的熟练程度。考虑到时间和材料是宝贵的资源，许多教育者正在寻求使用技术来提供对教员的低要求的补充教法。当前的研究使用了多基线设计来检验运动数学：弹跳应用程序对三位五年级学生的分数数量比较和数字线放置技能的影响。结果表明运动数学：弹跳提高了所有三个参与者的数量比较技能和一个参与者的号码线技能。此外，所有三名参与者均在测验前对一般分数知识进行了改进。讨论了对未来研究和干预实施的意义。
