For the international exchange of goods, an exact estimated time of arrival (ETA), especially in case of delays, is of great importance. Using global data of the automatic identification system (AIS) a grid node is generated. The sum of such nodes and their connections form a routing graph. As an example, with one node of in total more than 100,000 nodes it is described how this point gets the maximum vessel length and draft assigned.
This paper describes an emerging learning design for a popular genre of learner-generated video projects: Ideas Videos or iVideos. These advocacy-style videos are short, two-minute, digital videos designed “to evoke powerful experiences about educative ideas” (Wong, Mishra, Koehler & Siebenthal, 2007, p1). We draw on a recent study in teacher education to present a structured description of a pedagogical approach to iVideo filmmaking. A visual learning design representation (Agostinho, Harper, Oliver, Hedberg & Wills, 2008) and a LAMS-based generic learning design template (Cameron, 2008) form part of this description.
