LON-CAPA (The LearningOnline Network with CAPA) is a learning content and course management system. It offers an underlying shared content pool from which instructors across departmental and institutional boundaries can assemble granular learning content for their courses. It has strong assessment capabilities, both formative (homework and in-class using wireless PDAs) and summative (online and bubblesheet exams), with a one-source multiple-target strategy for the content. It offers students portfolio space in which they can stage materials for submission to projects, and provides a number of tools for synchronous and asynchronous student-student and student-faculty communication. LON-CAPA scales well with number of students, as load-balancing is possible across the whole network of servers at participating institutions.
MemAid is like a traditional flashcard program to help you memorize question/answer pairs, but with an important twist: it uses a neural network to schedule the best time for an item to come up for review. Difficult items that you tend to forget quickly will be scheduled more often, while MemAid won't waste your time on things you remember well. This means that your learning process becomes much more efficient, because the neural network gradually adapts to your personal memory model.
