OverviewStellar is the brand name for MIT's platform for course management and learning. Currently, this platform consists of a homean MIT-grown developed Learning Management System (LMS), Stellar 2.x, which has had an admirable history of intensive usability and accessibility testing and high responsiveness to user feedback. However, the current Stellar LMS is currently at a critical juncture in terms of scalability and applicability to the existing landscape of teaching and learning at MIT. In simple terms, the Stellar platform , launched in 2001, is showing signs of age. PDF |

Key issues facing the current platform include: - Technical and usability issues resulting from organic (rather than planned) and simultaneous growth on many fronts
.- Integration and functionality issues resulting from the inclusion of disparate third-party solutions and their interfaces
.- Code compatibility and stability issues resulting from partial, time-constrained and resource-dependent code updates for selected components
. resulting from the lack of a unified vision or strategy.The current Stellar LMS is also limited by major service hindrances on two fronts:- related to initial design decisions
The current platform's hard-coded architectural limitations and resultant pedagogical shortcomings undercut its core mission as a Learning Management System Its operational overhead for support and maintenance exceeds that of other possible alternative platformsWhile the latter issue primarily affects development and support staff, it nevertheless feeds into Stellar 2's instructional platform and user support challenges. The constraints imposed by the architecture - coupled with the fragility of the code and the high resource overhead required to alter it code - limit the upgradeability of the current LMS while engendering user dissatisfaction with its limited extensibility. Work-arounds designed to circumvent these service gaps necessitate resource-intensive manual intervention by developers. While they do fulfill use cases not accounted for within the application's main feature set, such work-arounds also generate additional overhead. All of these issues must be addressed if Stellar as a product is to come into its own as an Institute-wide Learning Management System worthy of MIT faculty and students. In Spring 2009, IS&T evaluated several products and services – Moodle 1.9, MoodleRooms, Drupal 6, Sakai versions 2x and 3, and BlackBoard Blackboard versions 8 and 9 – against functional requirements, data dependencies, and other key criteria for an LMS. viewpdf |
