  • I come from a family of engineers.That son I was talking about is a Mechanical Engineer working on PhDAs a computer scientist I barely qualifyWhen we talk about feedback loops, we can’t avoid getting into control theory.Open loopRequires a precise system to get predictable output.If the system breaks down and output goes haywire, input unchangedClosed feedback loopController adjusts the input to get predictable output
  • Feedback in education is pretty much the sameStudent is not a precise systemAnd we like it that way.Foolish to standardize the activities because variation among students is guaranteed to produce a wide variety of results.Son’s exampleOne exam in all of high schoolMeasure of mathematical competency reduced to a single integer between 1 and 100InfrequentSlowWeak

  • Everything You Need to Know about LRMI LRMI In Context Brandt Redd – Bill & Melinda Gates FoundationCC-BY 3.0 1
  • Control Theory SensorFeedback Reference Controller Input System Output
  • Pedagogical Theory AssessmentFeedback Standards Teacher Activities Student Skills Feedback must be: • Frequent • Fast • Rich
  • The PersonalizedLearning Model “What don’t I know?” CEDS SIF Learning Feedback PESC Loop Student Data LRMI Alignment LR Learning Objectives CCSS “How did I “How do I do?” learn this?” Assessment Content QTI, APIP W3C, IMS 4
  • Four-Layer Framework for Data Standards CEDS 2.0 Data Definition of data elements Depth of Systems Integration including name and Ease of Data Exchange and Dictionary interpretation.Broader Applicability and Longevity of Standards Data Logical definition of entities as groups of elements and Model inter-entity relationships. Concrete digital format for Serialization storage or transmission of entities. Transport layer and message Protocol formats for exchanging serialized entities.
  • Schema.org• Jointly Developed by Bing! Google and Yahoo• Specifies metadata schemas for common internet items. – E.g. Article, Blog, MusicRecording, Photograph, Recipe, SoftwareApplication, WebPage• Invited industry consortia to submit additions.CC-BY 3.0 6
  • “Potato Salad” DemoCC-BY 3.0 7
  • Aligning Content to CompetenciesLRMI addresses those metadata properties that distinguish content intended for learning. Learning Competencies Resources (Objectives or (Content) Achievement Standards) LRMICC-BY 3.0 8
  • Identifiers for the Common Core State Standards (CCSS) • Dot Notation CCSS.Math.6.NS.3 • URL http://corestandards.org/math/content/6/NS/3 • GUID 1F31DD363906484D9D2779A34FB59611 (http://corestandards.org/assets/E0330_ccss_identifiers.csv)CC-BY 3.0 9
  • Common Core Granularity 6.NS.3 Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.”CC-BY 3.0 10
  • Learning RegistryAn open exchange for metadata assertions. Assertion http://khanacademy.org/math/arithmetic/decimals/v/ Statement: dividing-decimals Teaches http://corestandards.org/math/content/6/NS/3 Stated by: http://khanacademy.org Provenance: When: 2011-10-23 13:45:27 59F8C29AD94C50A8D44F9357B32B89D9 Signature: 11CC-BY 3.0
