Embodied Design

Proportions

The extended version of the embodied design for proportions is implemented as a touch-screen application (Figure 1), where students can learn interactively how to solve a simple proportion problem such as 2:4 = 4:? (Figure 1). See the Instruction.
We have conducted eye-tracking studies with over a 100 students in primary and vocational schools (age 9-12), and recorded the hand movement, gaze behavior and thinking aloud conversation of the students.

 
Figure 1. Sample screenshots from enacting the proportion app. The task is to move two cursors orthogonal directions in an interactive task and try to get a green feedback on the screen. The green feedback occurs only if one puts his/her fingers at locations that have the same pre-set proportional distance from a base point (for example 1:4)

We study how the app can stimulate and support proportional learning. For example, how does the addition of geometrical shapes and lines (slopes) alter the way students act, perceive and reason? (Figure 2). The long-term goal of this project is to explore how mathematics education can benefit from embodied cognition research so that students can ultimately develop a better grip on mathematics.
