Math-Bridge Authoring
- 2. Plan • Overview of Content Creation for Math-Bridge • Static Learning Objects: – Creation • Formulae – Translation • Exercises – Simple – Advanced Feedback – Multistep • Metadata – For Static Learning Object – For Exercises • Ontology • TODO
- 3. Practical Issues • Internet Access Cards • Supported browser – • URL: http://devdemo.activemath.org/ • Login/Password: userX/userX
- 4. Individual Learning Objects • Role: the main building block of all the content • Type: Axiom, Theorem, Proof, Assertion, Method, Text, Example, Exercise • Language: – Can have as many as needed – Automatically choosing the language of the interface
- 5. Metadata • Descriptive – Title, Creator, Copyrights,.. • Pedagogical – Difficulty, Type, Target audience,… • Semantic – Relations between LOs
- 6. Courses and Tests/Exams • Consist of chapters – Consist of subchapters • … – consist of pages » Consist of individual LOs
- 7. Content Collections • Bags of LOs – Usually combined by a theory (section of Math knowledge), e.g. LeActiveMathCalculus collection – Usually combined by (a group of) authors, e.g. TUT collection • Only admins can create – Need them to hold LOs
- 8. Creation of Static LOs • Login • Enter Authoring • Press the button New and choose the target type of a LO to create
- 9. Creation of Static LOs • Login • Enter Authoring • Press the button New and choose the target type of a LO to create
- 10. Personal Workspace and Publishing • Any LO is created in a sandbox • Until ready, it is saved in a sandbox and is not available for the rest of the system • Once the author publishes a LO, it is added to the indicate Collection and can be added to courses, found through search and used by students
- 11. New Formula Editor A right click on a formula object launches the formula editor in the overlay mode If an edited formula is correct, the changes can be saved Formulae in the old content cannot be edited yet. They have a blue color instead of orange
- 12. Interacting with Formulae and other Objects • A right click on any of the objects (new formula, image, old formula) launches a context menu
- 13. New metadata interface • “Modify Metadata” button launches an overlay that allows to add and remove metadata elements
- 14. Practice-1: Creation of a static LO • Create an Axiom in your language of choice. – Provide a Title. – Add a collaborator. – Add rights “CC Attribution” – Add a Learning Time – Remove Learning Time • Save and Quit the tool • Open your axiom again. – Add another collaborator – Change the title • Save and Quite the tool
- 15. Existing Content • Already published LOs cannot be modified directly • A LO has to be copied to the workspace
- 16. Authoring Workflow Summary New LO? YES, creating new NO, modifying existent Start authoring Creator=You New LO is created in your Workspace NO, Licence forbids derivatives YES A new copy of the LO is created in your Workspace Contribuotr=You Are you already Creator or a Contributor of this LO NO When Publishing a new copy of the LO is created in the content base YES The LO is copied to your Workspace When Publishing the LO is added to the content base When Publishing the LO is updated in the content base Licence allows changes Not Possible Publishing LO If author is already a contributor or creator Existing learning object will be overwritten If NOT A new copy of this LO will be created with the author as a contributor
- 17. Translation of static LOs • Clicking the add language button launches a source/target overlay, creates a new language and copies-pastes the content and the objects
- 18. Practice-2: Translation of a static LO • Copy an example LO from any of the existing collections • Open it in your workspace • Create a new translation • Use the context menu to re-arrange objects • Save and Quit the tool
- 19. Practice-3: Creation of a Simple Exercise • Create an exercise with: – One task node – One interaction node – Two feedback nodes - one for the correct transition and one for the default incorrect one • Save it • Run it • Publish it • Find it using the search tool • Run it again
- 20. Practice-3: Creation of a Complex Exercise • Create an exercise with – more than 1 step – more than simple correct/incorrect feedback • Use syntactic, semantic and numeric diagnosis • Save and run you exercise
- 21. Ontology
- 22. TODO (1) • Formula Editor – Will try • As many symbols as possible • Metadata – For sure • Context-based control of available and necessary metadata fields – Will try • User-friendly ontology browsing • Static learning objects – For sure • Full support of existing LO translation and reuse • Authoring workflow – Will try • Integrate LO authoring with course/test assembly tool • Multiple browser support
- 23. TODO (2) • Exercises – For sure • Duplicate student input • Multiple/single-choice exercises • Parameterized exercises • Exercise templates – Will try • Multilingual support of exercise generation with domain reasoners • Translation/reuse of old exercises • Connection to an Algebra System • When? Discuss the Spring meeting schedule
