The study aimed to probe the effect of solving mathematical problems through using Mobile Learning (ML) on the seventh grade students' ability to solve them in Jordan. The study sample consisted of fifty-four (54) students of seventh basic grade in Zarqa in Jordan who were divided into two groups randomly: experimental group which included twenty-six (26) students who were taught through using mobile learning methodology and control group which consisted of twenty-eight (28) students who were taught through using the traditional ways of teaching. Mathematical problem solving test were prepared which were verified to check their validity and reliability. In general, the results related to problem solving and its dimensions revealed the understanding and reading of the problem, setting forth a plan for solving and implementing it as well as revising the solution). The students of the experimental group were taught by using mobile learning methodology were more excellent than their counterparts in the control group who were taught through using traditional teaching.
