Word Importer and Edit-In-Place Study Word Importer and Edit-In-Place are intended for users without XML knowledge to create a module in Connexions with ease. However, it is not known whether these tools are actually easy for users. Therefore, user testing has been carried out. New prototypes of Word Importers are being developed. Details |

Computer Menu Design Comparison |
|
 |
This research project investigated the tradeoff between space and usability in menu design. Two experiments were conducted to compare cascading menus and panel menus, which show all submenu items simultaneously in a two-dimensional panel. Both experiments found that panel menus performed faster than cascading menus and that panel menus were preferred to cascading menus when more realistic menu items were used.

This project was done at ETS, Princeton, NJ. It involved the design of a prototype of anassessment-based learning environment. The learning environment provides a variety of adaptive features. At the macro-adaptive level it adapts to students’ ages, native languages, culturalbackground and initial choice of difficulty levels. At the micro-adaptive level it integrates a Bayesian student model that is used to provide adaptive sequencing and feedback according to students' knowledge level and performance across items.
