RESEARCH

Research Interests and Fields

Inquiry based and technology assisted education methods and curriculum for science learning and scientific reasoning. Assessment instruments for assessing science content knowledge and scientific reasoning skills.
Measurement and assessment methods

  • Model Analysis – multi-dimensional modeling for assessing learning.
  • Dynamic models of learning and a unified probability framework for education measurement, which integrates Model Analysis, normalized gain and IRT under a single coherent theoretical frame.
  • Development of quantitative assessment instruments and methods for assessing content knowledge, reasoning, and views and attitudes.
  • Large scale quantitative assessment and targeted comparisons.
  • International assessment data center.

Computational models of student learning processes such as neural network models
Experimental technology and methods for measuring and modeling behavioral data of student learning (e.g. automatic group dynamics analysis and eye-tracking analysis of human interactions with computer simulations).
Technologies in education (e.g. in-class polling, web based interactive learning modules, technology enhanced science inquiry, virtual reality experiments, learning games)
