Abstract: An interactive networked classroom system including a teacher workstation with a base application, and one or more code segments. Each code segment includes a teacher version and a student version. The code segments include API links to a base application at the teacher workstation, or to helper functions such as plug-ins to the base application, such that the student version of the code segment has different rights, typically fewer and less powerful rights, than the teacher version of the same code segment. The teacher workstation forwards the student version of a code segment to student workstations that are in communication with the teacher workstation over a network facility; the student code segments may be embedded in a document corresponding to a classroom activity. Interactive classroom activities are then carried out using the code segments in combination with the base application.

Abstract: Method and apparatus for at least one of coding or decoding of data. The method comprising retrieving Extensible Markup Language (“XML”)-Unicode Transformation Format 8 (“UTF-8”) data, confirming XML-UTF-8 data in a proper format converting a prolog located within said XML-UTF-8 data, initializing a tag and attribute lookup table, comparing a current character to a plurality of multi-character patterns, determining whether said current character can be converted to a multi-character pattern in said plurality and Unicode, converting said current character to one of ASCII and Unicode when said current character cannot be converted to said multi-character pattern in said plurality, comparing at least one subsequent character to said plurality of multi-character patterns to determine conversion of at least the current character when said current character can be converted more than one way, determining whether there are more characters.
