The objective of the Leonardo project is to investigate technology-rich elementary science education with a focus on interactive scientific modeling and representational reasoning.

Research & Development Thrusts

  • Developing CyberPads, intelligent virtual science notebooks with sketch-based multimodal interfaces
  • Developing PadMates, CyberPad-embedded intelligent virtual assistants to support interactive scientific modeling
  • Evaluating the synergistic impact of intelligent virtual science notebooks and intelligent virtual assistants on elementary science learning

Demonstrated Efficacy and Results

  • Significant learning gains on students’ pre/post scores from Leonardo implementations of Electricity and Magnetism
  • Leonardo online teacher training successfully delivered online across multiple states
  • Extensive interviews with teachers using Leonardo find it to be of great benefit to elementary classrooms
  • Leonardo cyberlearning authoring system, Composer, developed for non-technical subject matter experts (ITS Generalized Framework for Intelligent Tutoring Systems Workshop 2014)
  • Pilot work on natural language analysis of student argumentation with Leonardo using LSA (AERA 2014, International Conference on Learning Analytics & Knowledge 2014)
  • Automated answer assessment techniques investigated for short answer textual responses (Workshop on Innovative Use of NLP for Building Educational Applications 2014)
  • “Sketch mining” techniques for automatically analyzing student visual renderings (Educational Data Mining 2014)

ComposerPageEditingAuthoring Technologies

  • Composer curriculum authoring tool facilitates authoring of curricular content by non-technical subject matter experts
  • Multiple authors can share and collaboratively develop curricular content for the CyberPad virtual science notebook
  • Agent dialogue and behavior authorable by non-technical subject matter experts
  • Web-deployed and cloud-based storage
