Computer programming is a difficult subject for most novice learners. Providing support that complements classroom learning could contribute to tackling the difficulties. Due to the ubiquity of mobile devices, such support can be provided by scaffolding the construction of programs on a mobile device. In order to design such a mobile intervention, learnersu2019 needs and limitations of mobile devices need to be placed at the center of the design process. This paper combines learnersu2019 needs and limitations of mobile devices to identify scaffolding strategies. Identification of scaffolding strategies is based on a scaffolding framework. Using specific examples, this paper will then show how the scaffolding strategies have been implemented on a mobile device.
