Abstract

User instruction on a computer system involves performing an interactive example and providing, in synchronization with the interactive example, explanatory information corresponding to the example. The explanatory information presented explains what most recently occurred in the interactive example and is updated automatically to correspond with the current state of the interactive example.

15. The method of claim 14 further comprising allowing the user to iteratively modify and execute a predefined interactive example.

16. The method of claim 1 further comprising providing in the explanatory information a jump to a utility for accessing source code associated with a predefined interactive example.

17. The method of claim 16 further comprising launching the utility for accessing the source code when a user of the computer system selects the jump.

18. The method of claim 1 in which the providing comprises presenting a prose description of the performed interactive example'"'"'s operation.

19. The method of claim 1 in which the providing comprises presenting a fragment of source code associated with the performed interactive example.

20. The method of claim 19 further comprising enabling a user of the computer system to view the source code fragment in a context of source code for the entire predefined interactive example.

21. A computer-based method of educating a user of a computer system, the method comprising:

generating a plurality of predefined interactive demonstrations;

performing one or more of the predefined interactive demonstrations relating to a selected topic;

receiving information from source code associated with the predefined interactive demonstration;

presenting the user with an annotation descriptive of the performed interactive demonstration in coordination with performance of the predefined interactive demonstration; and

allowing the user to selectively explore different aspects of the performed interactive demonstration, the annotation, or both;

wherein;

generating the predefined interactive demonstration includes extracting the received information from source code associated with the predefined interactive demonstration, and

presenting the annotation descriptive of the performed interactive demonstration includes extracting the received information from source code associated with the predefined interactive demonstration.

22. A computer-based instructional system comprising:

a plurality of predefined interactive examples, each predefined interactive example being selectively executable by a user of a computer system;

annotations describing each predefined interactive example, different annotations being provided automatically in response to and in synchronization with selective execution of a predefined interactive example; and

a unified body of source code associated with a predefined interactive example;

wherein;

each predefined interactive example is built by extracting information from the unified body of source code associated with that predefined interactive example, and

annotations describing a predefined interactive example are built by extracting information from the unified body of source code associated with the predefined interactive example.

23. The system of claim 22 further comprising a utility through which the user can access source code associated with a predefined interactive example.

24. The system of claim 23 in which the utility enables the user to view, copy or modify a predefined interactive example'"'"'s source code.

25. The system of claim 22 further comprising a body of reference information selectively accessible to the user.

26. The system of claim 25 further comprising a link that provides the user with direct access to an item of information within the body of reference information.

27. The system of claim 26 in which the link is a visually indicated marker on which the user can click a cursor.

28. The system of claim 22 in which the annotations comprise textual descriptions of the predefined interactive example.
