Abstract: A learning content delivery system is provided that includes a network, a plurality of remotely stored content delivery applications each having learning content, one or more user devices, and a platform. The platform has an application framework that allows the one or more user devices to access the remotely stored applications and learning content via the network. The applications can include at least two platform specific applications, which are developed on a common application programming interface. The platform can dynamically sense one or more attributes of each user device and to customize presentation of the learning content from the platform specific applications for the user device. The application framework can provide two-way awareness between the platform and the platform specific applications.
