CATS - Computer Assessable Task System


Introduction | Goals | Overview | Publications | Prototype Software | Team


Introduction

CATS is a model of an interactive computer assessment system that allows:
  • Students to solve elaborated mathematical problems, while being given feedback on their mistakes.
  • Teachers to easily build new complex interactive problems from a pool of pre-defined modules.

    Goals

    The aim of this project is the construction of a task-based computer assessment system, that proposes problems to students, and then guides, assesses, and provides feedback, throughout the resolution process.

    The model we devised for CATS is general enough to allow both teachers and students to deal with basic as well as complex tasks while keeping a simple structure at concept level.

    Teachers using CATS contexts and tools for task construction, will be able to provide specific libraries of problems to guide his students and, eventually, to share their libraries with a community of users.

    We aim at building an open source prototype that is, on the one hand, powerful enough to allow the definition of complex tasks, and, on the other hand, light enough to be accessible to end users through a CD, or through web downloading.
