Abstract

Methods and apparatus are provided for storing and providing access to content components representing solutions to published text-book problems. Tutorials are composed of solution, which in turn are composed of problem descriptions, solutions, hints, steps, queries, Socratic queries, formulas and figures, and guesses. These solutions can be stored in a relational database, or in files using the HM(SL format.

Claims

1. A database apparatus for storing educational content comprising:

a collection of content components;

a collection of tutorials,

a collection of user profiles;

a mapping between tutorials and content components;

a mapping between user profiles and tutorials;

a collection of sessions; and

a collection of stored procedures.

2. An apparatus as in claim 1 wherein the said components are selected from group consisting of problems, group consisting of problem sets, group consisting of problem descriptions, group consisting of problem statements, group consisting of hints, group consisting of questions, group consisting of Socratic questions, group consisting of guesses, group consisting of queries, group consisting of steps, group consisting of figures and group consisting of images.

3. An apparatus as in claim 1 wherein said components are described in the HM/SL language.

4. An apparatus as in claim 1 wherein said tutorials are selected from a group of solutions, each comprising hints, questions, guesses and steps.

5. An apparatus as in claim 4 wherein the first element in each said solution is a hint.

6. An apparatus as in claim 4 wherein each question and hint is followed by a step.

7. An apparatus as in claim 4 wherein each step, except the last step, is followed by either a question or a hint.

8. An apparatus as in claim 4 wherein each question has at least two guesses, and at least one right guess.

9. An apparatus as in claim 4 wherein each guess has at least one response.

10. An apparatus as in claim 4 wherein each solution record includes at least a problem index, problem number, book title, chapter title, section title, problem set, page number, solution number, XML encoding of the solution, and information about the author.

11. An apparatus as in claim 10 further comprising a database of comments, wherein comment is stamped by a date and refers to a problem index or a solution index.

12. An apparatus as in claim 1 further comprising a database of books, wherein book record includes a text code, text name, edition, publisher, publication date, author, ISBN, and an image of the cover.

13. An apparatus as in claim 1 wherein the said profiles are stored in records which include problem index, user code, grade, grade date and comments.

14. An apparatus as in claim 4 wherein the said tutorials are stored in solution files having a header listing the problem that the tutorial is solving, a code name for the source book and author, and specification of the problem location in that book.

15. An apparatus as in claim 14 wherein the specification of the problem location includes a chapter, section, group, page number and problem number.

16. An apparatus as in claim 4 wherein solutions comprise of hints, guesses, queries, Socratic questions, steps, figures and images.

17. An apparatus as in claim 16 wherein said steps are stored in sequences using an HM/SL format, and have headers identifying a partial solution to a problem

18. An apparatus as in claim 17 wherein said steps include images or graphics.

19. An apparatus as in claim 16 wherein said hits are stored using an HM/SL format, and have headers identifying a clue that the student can display on request.

20. An apparatus as in claim 16 wherein said queries are stored using an HM/SL format, and have headers identifying different ways of continuing the solution.

21. An apparatus as in claim 20 wherein headers specify when queries should be presented to the student.

22. An apparatus as in claim 20 wherein headers specify, for each query, the text of the query followed by at least two Guess-Response pairs.

23. An apparatus as in claim 22 wherein guess-response headers specifying the item that the student will see if the corresponding guess is selected.

24. An apparatus as in claim 16 wherein guess short text representing one possible answer to the query that it follows.

25. An apparatus as in claim 16 wherein figure headers specify an image generated with a drawing or graphing program

27. A method as in claim 26 wherein the step of accessing a tutorial is preceded by a step of uploading that tutorial by aggregating it into a file and transmitting it to a web-server.

28. A method as in claim 27 wherein the said file has a header listing the problem that the tutorial is solving, and a code name for the source book and author.

29. A method as in claim 26 wherein each tutorial is assembled from a set of solutions, each comprising hints, questions, guesses and steps.

30. A method as in claim 29 wherein the first element in each said solution is a hint, each question and hint is followed by a step, each step, except the last step, is followed by either a question or a hint, question contains at least two guesses, and at least one right guess, and each guess has at least one response.

31. A method as in claim 29 wherein said steps are stored in sequences using an HM/SL format, and have headers identifying a partial solution to a problem

32. A method as in claim 31 wherein said steps include images or graphics.

33. A method as in claim 29 wherein said hints are stored using an HM/SL format, and have headers identifying a clue that the student can display on request.

34. A method as in claim 29 wherein said questions are stored using an HM/SL format, and have headers identifying different ways of continuing the solution.

35. An apparatus as in claim 20 wherein headers specify when queries should be presented to the student.

36. An apparatus as in claim 20 wherein headers specify, for each query, the text of the query followed by at least two Guess-Response pairs.

37. An apparatus as in claim 22 wherein guess-response headers specifying the item that the student will see if the corresponding guess is selected, and short text representing one possible answer to the query that it follows.

26. A method for storing and accessing educational content including the steps of:

accessing the profile of a user;

accessing a tutorial;

accessing content components;

updating content components;

updating the tutorial information;

updating the profile of the users; and

generating a response transmitted over the world-wide-web.
