Goals of this presentation

  • Introducing the new model of education
    • Core ideas and concepts
    • Ongoing research work on infrastructures and algorithms
  • Revealing the connection between the new model and complex networks
  • Shoot your questions at me on the moment

Outline

  • The New Model of Education
    • The $1+5$ levels of knowledge, and the connection among them
    • Learning within the same layer and across layers
    • From learning to creating knowledge, the levels of creativity
  • The network perspective: learning and testing over knowledge networks
  • Take-home message

The $1+5$ levels of knowledge

  • Level 0, Pre-knowledge: experiences
  • Level 1: factual and procedural knowledge
  • Level 2: disciplinary concepts
  • Level 3: disciplinary big picture
  • Level 4: general ways of thinking cross and above disciplinaries
  • Level 5: ways of teaching and learning
disciplinary big picture
  • Typical research objects
  • Typical research questions
  • Typical ways of analysis
  • Typical ways of thinking
  • Typical responsibility of the discipline for the world
  • Identifying questions that should/can be investigated in the discipline

Connections among the $1+5$ levels of knowledge

  • Concept formation: from low to high
  • Concept generation: from high to low
  • Concept assimilation: within the same level
  • Advanced knowledge generators, the $3+$ level knowledge

Learning via walking on the $1+5$-layer knowledge network

  • Currently, more often, learning (rote learning) happens within the same layer
    • memorizing factual knowledge
    • repeatedly practicing procedural knowledge
  • However, cross-layer paths provides often more efficient ways of learning
  • Learning via experiencing creation

Seamless transition from learning to creating

  • Identifying research objects and questions
  • Solving the problems with typical ways of thinking and analysis
  • Even creating the advanced knowledge generators

A network perspective of the new model of education

  • Knowledge is presented as a multilayer network, with a linking phrase on each link
    • the shape of the Sun, level 0
    • to form the character “日”, concept formation
    • “日”$+$“召” makes “昭”, level 1, concept assimilation
    • picto-phonetic compound, level 2

A network perspective of the new model of education

  • Knowledge is presented as a multilayer network, with a linking phrase on each link
    • making use of concept formation/assimilation/generation to understand Chinese characters, level 3
    • generalizing this way of learning to other concepts, level 4 and 5

Multilayer network model of knowledge

A network perspective of the new model of education

  • Learning within the same level and cross levels helps each other
  • Creating knowledge often involves cross-level walking
  • Learning and testing over knowledge networks

Learning and testing algorithms, and beyond

  • Besides using the connections when learning each individual concept, also
  • Recommendations of learning orders
  • Diagnostic testing of each learner’s known concepts
  • Evaluative testing

Learning and testing algorithms, and beyond

  • Core questions on teaching and learning
    • What to teach/learn, why
    • How to teach/learn, why
  • Can the network model help to answer those questions too?
    • Identifying big ideas/concepts
    • Annotate the levels of teaching and learning

Diagnostic testing algorithm

  • Instead of testing each concept independently, use links to determine
    • which concept to test
    • how to infer from the testing results
  • Bayesian Network
    • not knowing “刀”(“triangle”) likely also not knowing “召”(“right triangle”)
    • knowing “召”(“right triangle”) likely also knowing “刀”(“triangle”)
  • Usage frequency order

Learning orders

  • Concepts that should be learned first
    • the basic/root ones
    • the most used ones
    • the ones with the most outgoing links
  • Cross-layers models are more complicated, thus only results on within-layer learning are presented today

Modeling the learning process

  • To check or even find optimal learning orders
  • To show that the advanced knowledge generators help to learn more efficiently
    • As a diffusion process over the multilayer network of knowledge
    • With additional models of adaptive learning cost

Identifying big ideas/concepts

  • A big concept is a concept that, once understood, can help to learn many other concepts
  • Ideally advanced knowledge generators(AKG) are exactly so
    • Can we verify this using the multilayer network model of knowledge?
    • How to relate AKG to the previously vaguely proposed big concepts

Identifying big ideas/concepts

  • A big concept can be
    • the basic/root concepts
    • the concepts with more offsprings
    • the concepts with more in-coming links
    • the concepts with more outgoing links
    • the most influential ones defined via PageRank-like algorithms

Big elementary school math concepts

Experiments to check the validity of the above answers

  • Test of the diagnostic testing algorithms
  • Lab and neuroscience studies, and later classroom studies on
    • meaningful v.s. rote learning, with/without advanced knowledge generators
    • with/without the recommended learning orders
  • Correlation between creativity and meaningful learning toward advanced knowledge generators

Summary

  • Multilayer network: A mathematical model of knowledge and education
  • Typical questions of education become math problems
  • (We are good at) Solving them, and checking the validity of those solutions experimentally
  • Implementing the system in school learning and enterprise learning, and for other disciplines

Meaningful learning over human knowledge highway

  • All levels of knowledge in all disciplines and their connections are represented as a concept map
  • Wiki page on each concept, including an explanation in text, figures, and video
  • Example of the creation and creative usage of the concepts
  • Learning and testing algorithms behind it

Meaningful learning over human knowledge highway

  • Learning towards the advanced knowledge generators, meaningfully
  • Learning to become whatever you would like to become, without the limit of disciplines and fixed paths
  • Cultivated, protected, and encouraged to be creative, to go beyond
  • Maybe even creating new advanced knowledge generators

Take-home message

  • This is the way
    • to go beyond AI with unlimited factual and procedural knowledge
    • let the network-based education revolution begin
    • let us contribute to the development of Educational System Science
  • Let us make a difference, together
  • Let us be movers
