Geometry LearnLab course description

The Geometry LearnLab course is described here.

Algebra & Geometry LearnLab Course Committee

The Math Course Committee meets monthly and is led by Albert Corbett (corbett@andrew.cmu.edu).

Teachers (and perhaps researchers) can find answers to questions on the FAQ for teachers.

Geometry Learnlab Studies

• Contiguous Representations for Robust Learning (Aleven & Butcher)
• Mapping Visual and Verbal Information: Integrated Hints in Geometry (Aleven & Butcher)
  • Training Geometry Concepts with Visual and Verbal Sources (Burchfield, Aleven, & Butcher)
• Visual Feature Focus in Geometry: Instructional Support for Visual Coordination During Learning (Butcher & Aleven)
• Using Elaborated Explanations to Support Geometry Learning (Aleven & Butcher)
• Hints during tutored problem solving – the effect of fewer hint levels with greater conceptual content (Aleven & Roll)
• Does learning from worked-out examples improve tutored problem solving? (Renkl, Aleven & Salden)
• Tutoring a meta-cognitive skill: Help-seeking (Roll, Aleven & McLaren)
• What is difficult about composite problems? (Kao, Roll)
• Using learning curves to optimize problem assignment (Cen & Koedinger)
• Geometry Greatest Hits (Aleven, Baker, Butcher, & Salden)

These studies are also organized within research clusters that address common issues across a variety of academic content domains: Coordinative Learning, Interactive Communication, and Refinement and Fluency.
