IMS Content PackagingQTI Seminar on IMS Content Packaging & Use of QTI Wilbert Kraan

TRANSCRIPT

  • Wilbert Kraan IMS Content Packaging, QTI, LTI and EDUPUB
  • Introduction This presentation aims to outline the history, design and use of IMS Content Packaging, Learning Tools Interoperability and IMS Question and Test Interoperability.
  • Overview About CETIS and myself IMS Content Packaging IMS Question and Test Interoperability assessment IMS Learning Tools Interoperability EDUPUB and IMS specifications
  • About CETIS and myself About CETIS: Started in 1999 as the UK IMS centre funded by JISC (compare: AXIES?) Became the Centre for Educational Technology and Interoperability Standards at the University of Wales, Bangor 2006: JISC CETIS innovation support centre Now: CETIS at the University of Bolton About me: Co-chaired IMS Content Packaging 1.1.4 and 1.2 Co-chaired IMS QTI 2.1
  • About IMS Content Packaging The original aims and basic design History An example Difference with EPUB Variants and profiles: SCORM 1.2 SCORM 2004 IMS Common Cartridge Convergence with other specs: RAMLET
  • IMS CP: aims and basic design Aim: interoperability between systems that import, export, aggregate, and disaggregate packages of content Typical systems: Learning Management Systems (LMSs), repositories and authoring tools
  • IMS Content Packaging: history 1999: IMS CP 1.0 base document 2001: IMS CP 1.1.2 final released; widely adopted 2004: IMS CP 1.1.4 final released; used in SCORM 2007: IMS CP 1.2 public draft 2 released 2009: ISO 12785 international standard released: same as IMS CP 1.2 pd 2
  • IMS CP: Demonstration Reload packaging tool: http://www.reload.ac.uk/ Moodle LMS: https://moodle.org/
  • IMS CP: difference with EPUB Supports more than one table of contents/organization Allows any type of content to be aggregated e.g. Flash, Word docs, PDF, IMS QTI, etc. Widely implemented in Learning Management Systems (often as SCORM or Common Cartridge) Has been integrated with many learning technologies: Learner activity tracking (CMI) Eportfolios Learning Design QTI No current plans for further development
  • IMS CP: variants and profiles SCORM 1.2 (2001) Adds an IEEE Learning Object Metadata profile Adds IEEE Computer Mediated Instruction (CMI) javascript LMS to content communication API Adds Sharable Content Object (SCO) concept Removes a lot of optionality SCORM 2004 Adds adaptation of content to learner via IMS Simple Sequencing
  • IMS CP: variants and profiles IMS Common Cartridge (1.0 2009 1.3 2013) Adds Learning Tools Interoperability (LTI) descriptors Adds forum discussions Adds web links Adds a QTI 1.2 profile Adds content types for Interoperable WhiteBoard (IWB), EPUB, APIP/QTI Defines package structure Removes optionality
  • IMS CP: convergence with other specifications- IEEE RAMLET Resource Aggregation Model for Learning, Education and Training Abstracts over several formats: METS IETF Atom MPEG 21 DID IMS CP OAI ORE Maybe EPUB? Resource Aggregation Format 1 Resource Aggregation Format 2 Resource Aggregation Format 3 RAMLET Conceptual Model
  • About IMS Question and Test Interoperability History and purpose QTI 2.1 parts and their functions Tools demonstration Accessible Portable Item Protocol Current implementations Future developments A possible future for QTI Integrating QTI 2.1 into HTML5
  • QTI's purpose Make assessment items, tests and results interoperate between all relevant systems
  • QTI history and characteristics Developed since 2001 QTI 1.x No relation to HTML at all Typically implemented in Flash, Java or HTML QTI 2.x Uses a modular W3C profile of XHTML in its own XML item document format
  • QTI 2.1: parts Items XML format for question semantics and response processing- independent of styling Tests XML format for test definition, results processing and test navigation Packaging and metadata Binding of QTI items and tests to IMS CP and metadata Results XML format for assessment results, usage statistics and psychometrics
  • QTI 2.1: Tools demonstration A Jisc sponsored editor: Uniqurate http://uniqurate.kingston.ac.uk/Uniqurate/menua ction Open source The QTI 2.1 reference implementation: QTIWorks https://www2.ph.ed.ac.uk/qtiworks/ Open source; the JQTI engine is used in many other QTI implementations
  • QTI 2.1: Accessible Portable Item Protocol IMS Accessible Portable Item Protocol (APIP) adds optional accessibility content to QTI items that are triggered by learner profiles
  • QTI 2.1: current implementations Netherlands: Whole school system moves to QTI for assessment Germany: Several university consortia use Onyx QTI system France: MOCAH QTI system used in schools South Korea Large scale school experiments with QTI tools, including integration in EPUB schoolbooks USA $300 million Race To The Top initiative to overhaul online assessment infrastructure around APIP/QTI
  • QTI 2.1: development plans Portable Custom Interaction Javascript API to integrate any interaction into a QTI item Agreed QTI 2.2 Adds more HTML5 features, including BIDI and Ruby Agreed aQTI Integrates W3C specs: WCAG, ARIA and HTML5 Takes QTI to the presentation phase
  • A possible future for QTI?
  • Integrating QTI 2.1 into HTML5 Mike Aumock's proposal Steve Laye's proposal
  • About IMS Learning Tools Interoperability (LTI) Basic function Access control and anonymity Security Current developments LTI 1.3 LTI 2.0 Content Item Message service
  • IMS LTI: basic function Hands over user session from a Tool Consumer (TP, typically an LMS) to a Tool Provider (TC, typically a specialised web tool or premium content from a publisher)
  • IMS LTI: access control and anonymity Required attributes in a Basic LTI launch POST from tool consumer to provider: Message type LTI version Unique resource link Recommended but optional attributes: Link title Link description User image User role User name/email Context ID Context type Target (iFrame) Launch styling Return URL Tool consumer info Institutional info
  • IMS LTI: security
  • IMS LTI: current developments LTI 1.2 Adds tool profile: lists services supported Optional outcomes service: send marks back from tool provider to consumer Content Item message service Allows user to pick content from a publisher's tool provider and integrate it into the tool consumer LTI 2.0 Allows deeper integration Allows services to be defined and advertised by users
  • EDUPUB and IMS Specifications Two ways of integrating IMS specifications in EDUPUB: My 2013 EPUB experiment Works in standard e-readers Adapts to e-reader: progressive enhancement Uses QTI HTML for internal rendering No IMS Caliper capability IMS' official 2014 EDUPUB implementation Works in a special version of Readium only Uses QTI JSON & Angular.js for internal rendering Includes IMS Caliper Sensors
  • My experiment: Balancing effectiveness with robustness Most interactive Most devices Static QTI HTML inside EPUB3 OK experience Long lived Works anywhere But: No feedback No analytics No results (unless the user clicks a link) QTI HTML + javascript inside EPUB3 Good experience Reasonably long lived No server infrastructure But: No results or analytics May need some work with e-reader vendors EPUB3 to online quiz tool via IMS LTI Best experience Secure Quiz results return to college, analytics possible But: Potential longevity issues May need work with e- reader vendors Needs an analytics ID transfer solution
