Abstract: This paper is a following up to one presented in 2010 at the AACE. Since 2009, the Apple iPhone and iPod touch have become an integral part of student learning experiences at Abilene Christian University (ACU), with all in-coming freshmen being provided one of these mobile devices. This paper shares the experiences of the authors from teaching a lab-intensive undergraduate introductory course on mobile computing at ACU in 2010 to the present challenges. Discussed within this paper are the authors’ experiences meeting the challenges of the rapidly developing landscape of mobile application development. The paper concludes with a direction for future courses in mobile computing at ACU.
