decide on location of equation in 'Sandwiches' and 'Molecules' screen #7

Closed pixelzoom closed 9 years ago

pixelzoom commented 9 years ago

As of 1.0.0-dev.2 ... The position of the equation in the 'Sandwiches' and 'Molecules' screens is controlled via the 'equation' parameter, which puts the equation at the 'top' (default) or 'bottom' of the screen. There is a tiny bit of logic involved in supporting this (see RPALBaseView), but it would be good to decide on one approach and remove the unused code and query parameter.

This is a design issue which will be finalized after interviews.

Decision: Equation at the top

Rationale: Equation at the bottom results in substantially more occlusion of the equation during interviews and absolutely no students drawing connections between the equation coefficients and the molecules. Equation at the top tends to result in students actively referring to the equation in the first two screens (with both gestures and through the patterns of use that suggest they are connecting the equation to the number of molecules they add to the reaction boxes).

Done, closing.
