### 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)
- 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.
