The aim of this study is to compare the difficulties that novice instructional designers experience during instructional design processes for mobile devices and desktop computers. The participants/instructional designers of this study include 68 sophomore students from a Computer Education and Instructional Technologies (CEIT) department. The participants developed learning content for mobile devices and desktop computers through the ADDIE model. A descriptive research method was used for the present study. An already developed scale in line with the ADDIE model was used to collect the data. Descriptive statistics, Mann Whitney U and Kruskal Wallis tests were conducted to analyze the data. The results of this study indicated that the difficulties experienced in both processes tended to be similar in developing learning content. Difficulties in internal design and production and front-end analysis were significantly different in terms of the Internet connection in personal mobile devices. External design and development difficulties, rolling-out difficulties and total scores were significantly different with regard to levels of Internet experience. (C) 2014 Elsevier Ltd.
