With the advent of mobile technologies such as iPad tablets, new kinds of interactions with subject matter have become possible that have potential for improving learning. The present study used an experimental repeated measures crossover design to investigate whether the iPad fractions game Motion Math would improve fourth graders\u2019 fractions knowledge and attitudes. In results from 122 participants, students\u2019 fractions test scores improved an average of over 15% after playing Motion Math for 20 min daily over a 5-day period, representing a significant increase compared to a control group. In addition, children\u2019s self-efficacy for fractions, as well as their liking of fractions, each improved an average of 10%, representing a statistically significant increase compared to a control group. Implications for the design and study of interactive games are discussed.<\/jats:p>","DOI":"10.1177\/1555412013496894","type":"journal-article","created":{"date-parts":[[2013,8,27]],"date-time":"2013-08-27T06:13:47Z","timestamp":1377584027000},"page":"186-214","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":110,"title":["Results From a Controlled Study of the iPad Fractions Game Motion Math"],"prefix":"10.1177","volume":"8","author":[{"given":"Michelle M.","family":"Riconscente","sequence":"first","affiliation":[{"name":"Rossier School of Education, University of Southern California, Los Angeles, CA, USA"},{"name":"New York Hall of Science, Queens, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2013,8,27]]},"reference":[{"key":"bibr1-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1080\/10508406.2011.611446"},{"key":"bibr2-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8721.00196"},{"key":"bibr3-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1037\/0033-295X.84.2.191"},{"key":"bibr4-1555412013496894","first-page":"91","volume-title":"Acquisition of mathematical concepts and processes","author":"Behr M.","year":"1983"},{"key":"bibr5-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1016\/S0166-4115(08)60099-0"},{"key":"bibr6-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-5834.1996.tb00535.x"},{"key":"bibr7-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1016\/S1364-6613(99)01361-3"},{"key":"bibr8-1555412013496894","volume-title":"Mathematics equals opportunity","author":"Department of Education","year":"1997"},{"key":"bibr9-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1016\/0010-0277(92)90050-R"},{"key":"bibr10-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1080\/10508406.2010.508029"},{"key":"bibr11-1555412013496894","first-page":"50","volume-title":"Mathematics Education in the Middle Grades: Proceedings of a National Convocation and Action Conferences","author":"Hart K.","year":"2000"},{"key":"bibr12-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1037\/0012-1649.17.3.300"},{"key":"bibr13-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1207\/s15326985ep4102_4"},{"key":"bibr14-1555412013496894","doi-asserted-by":"publisher","DOI":"10.1177\/0013124585017004006"},{"key":"bibr15-1555412013496894","doi-asserted-by":"publisher","DOI":"10.2307\/748774"},{"key":"bibr16-1555412013496894","first-page":"225","volume-title":"Serious educational game assessment: Practical methods and models for educational games, simulations and virtual worlds","author":"Johnson-Glenberg M.
